If you are reading The Cureality blog chances are you care about your health. You care about what you eat. You want to remain healthy, free of disease, feel good and possibly even want to look and feel as vibrant as you were when you were 20. Many of us think of food all day long. Many of us love to eat. We plant gardens so we know our food is free of pesticides and other toxic chemicals. Food can be a cause of disease and it can minimize our chances of disease. We try and take care of our insides but did you ever wonder what in the world you apply to your skin on a daily basis? What do these products contain and are they safe? Why are there more endocrine disorders popping up. Could it be that some of things we apply to our skin every single day may be harmful to our insides?

A portion of the skin health section of Cureality will take a look at skincare products and cosmetics. Are the products we apply to our skin gluten-free, paraben-free and free of other harsh chemicals that can cause skin irritations and possible other unwanted diseases. I came across Mirabella cosmetics and I wanted to learn more about this particular product line so I tracked down John Maly, founder and CEO of Mirabella Cosmetics. Mr. Maly was gracious enough to take time out and answer my questions.This is what Mr. Maly has to say about Mirabella:

DD: Tell us about some key features about Mirabella, gluten-free cosmetics. What made you get started in a gluten-free line?

JM: We didn't start as gluten-free. Over time we have continued to make our line more beautiful AND more healthy for women. First we began with a mineral foundation. Then as we introduced new products, we made sure they were as clean and healthy, while still being fashion forward. We saw the benefits to our clients to take out those ingredients that didn't help them look and feel their best such as glutens, parabens and talcs.

DD: Some cosmetic companies carry partially gluten-free cosmetics. Are all of Mirabella products gluten-free, paraben-free and talc-free?

JM: Everything is paraben-free and talc free. And our brand is all gluten-free except our Skin Tint Creme foundation. That is a product that women love and we just cannot make the formula without a wheat protein to perform as well...yet! We will continue to work on it!

DD: Are there other ingredients in cosmetics that women should be cautious of using if they have skin sensitivities or allergies?

JM: Some women are sensitive to fragrance as well.This is another thing that we avoid with our brand. The biggest ingredients that women find that helps with their skin health is mineral products. They are natural and very breathable on a woman's skin.

DD: I think your velvet lip pencils are by far the most extraordinary lip pencil on the market. What are some of your other standout products your customers love?

JM: Pure Press Mineral Foundation is still our #1product. But the fastest growing product is Magic Marker Eyeliner. It is easy to use, doesn't smudge and lasts all day.

DD: Anything new on the horizon for Mirabella that you can share with us?

JM: In August we launch CC crème. This product has all the good for you ingredients to help with Anti-Aging like avocado oil, argan oil and Acai (Assai) berry. Plus it is a mineral formula, gluten-free, and paraben-free. And it has an SPF of 20. One of the biggest issues that women have with aging is lips. That is why we put Litchi Chinesis Fruit Extract in our Colour Vinyl lipstick. Then in your favorite Velvet Lip Pencil, we put Pomegranate Extract, Vitamin C and E in to assist with in Anti-Aging.

DD: Is Mirabella only sold in the US or do you have international distribution as well.

JM: We are sold in Canada, Australia, Finland and Russia.

DD: Where can we purchase your cosmetics?

JM: Our products are available at www.mirabellabeauty.com and at over 1,500 of the finest salons and spas. Go to our salon locator to find a retailer near you.

When it comes to mud runs, Tough Mudder is a big deal. This event covers ten to twelve miles of muddy running interspersed with challenging obstacles. Using the word “challenging” when describing the obstacles along the course is an understatement. Obstacles include getting an electrical shock, running through ice-cold water, jumping over fire, climbing over walls, and things you’ve seen when watching American Ninja Warrior. Plus these obstacles are all done on a rugged, muddy terrain. So, maybe the word dirty-insane-challenging would be a better fit to describe the Tough Mudder.

Don’t let this description lead you to think that this is an impossible feat. The Tough Mudder website states that 1.3 million people have completed this event since it’s inauguration. If Tough Mudder is on your bucket list, know that if they can do it so can you. Here are 5 tips to get you ready to tackle the Tough Mudder.

1) Train: This tip seems obvious, but it’s not. Many people are standing at the start line hoping for the best. This strategy puts you at high risk for injury and not completing the event. You need to train anywhere from 8 to 12 weeks for the Tough Mudder. Use this guideline if you have a regular workout routine established. If you’re new to exercise or have been on a workout hiatus you may need 4 to 6 months to get ready. Carve out time in your schedule to train 3 to 5 days a week to prepare for this event. If you need some guidance, join a training program to provide a road map to Tough Mudder success.

2) Run: Tough Mudder is like a half-marathon on steroids. Running is critical component when you find that you’re traveling up to a mile between obstacles. Incorporate running intervals, hills, and fartleks into your training program. Start your training off with a new pair of running or minimalist shoes so that by the time your Tough Mudder comes around your shoes are ready to get trashed.

3) Simulate Obstacles: To feel confident at the start line of Tough Mudder, you need to practice skills that can help you with the obstacles. This will reduce your risk of obtaining any injuries during the event. Utilizing stairs, fences, playgrounds, rock climbing walls, football fields, lakes, and beaches are great places to start when looking to simulate obstacles. Check out the Tough Mudder website to see a list obstacles. Use your imagination to find ways to incorporate obstacle training in your workouts.

4) Simulate Terrain: Running covered in mud with wet shoes is much different from running on the treadmill. Running in the grass, on the sand and through the water is much different from running on asphalt. Get ready to be a little uncomfortable. Your shoes will begin to slide around on your feet and your clothes will cling to your body. Get ready to work a little harder. Your stride will be affected by the changes in terrain. Practice running on the grass, in the water, and in the sand. Make sure you get wet and run with soaked shoes and clothes. You’ll realize what shoes and clothes to wear on race day to be the most comfortable and effective.

5) Team: Teamwork is what Tough Mudder is about. Teamwork is what keeps drawing people back to the Tough Mudder venue. From the start to the finish, it’s about getting everyone across the finish line. If you’re struggling to get over a wall, a hand is there to help pull you up. When fatigue is setting in, another person is there to bring up your spirits. You’re not alone out there. At other races you find you’re left in the dust. At Tough Mudder you are overcoming challenges with your muddy buddies. Get together with friends or a training group to form a team bond that will keep you accountable with your training and support you to the finish line.

On Saturday my husband and I took our niece Anna out her annual birthday date. That date started with a trip to the Humboldt park playground. As with most kids, Anna ran straight to the spider-web jungle gym which I have to admit it looked pretty cool. Just before she began to climb up, she turned to look at me and said “Auntie Amber, climb up too!”

I was not wearing my playground apparel on Saturday. I had a cute pair of pink loafers on, skinny jeans, tank and a jean jacket. But it did look like fun so I decided to climb. No problems yet. I was good to go climbing around on the ropey, spider web apparatus. But of course, just climbing around was not enough. Anna suggested that we should race. Not just to the top, but to the top of the jungle gym over the side, across the rope bridge and down the slide. This is when my skill was put to the test.

As you could have guessed, Anna smoked me during our race. Not only that, but the jean jacket was off and I was working up a sweat. Was I getting a workout from my 9-year-old niece? I think so. But we both were having so much fun. We continued to climb up and down the fake rock wall, monkey bars and run around the playground. It was a blast.

But as I looked around the playground, I was the only adult climbing around the playground and playing. The other adults were sitting on park benches watching. One parent near by had to decline the request of a child they were with to join them on the playground equipment. I felt really good that I could be there with my niece running around, climbing and swinging.

Keeping up with our kids, grandkids, nieces and nephews is really important as we age. Otherwise we sit on the sidelines. How do you train for the playground? Get in the weight room. Lift heavy things, jump, pull yourself up, move side ways, and challenge your body to do movements beside sitting or standing. If it’s been awhile or you’re just not sure where to start then get a trainer and join some group workouts.

It’s time to get moving. Because it starts out at the playground now but soon it will be mud runs, Frisbee, triathlons and weekend football games. You need to keep up!

Vegetables are arguably the most important food group, the key to any healthy diet. They are one of the most nutrient dense food groups and serve the foundation to healthy meals and snacks. A frequent comment from people enjoying the Cureality way of eating is, “I am eating more vegetables than I ever have in my life!”

This is great because plentiful consumption is associated with decreased heart disease, reduced weight, lower blood pressure, glowing skin and decreased risk of some cancers. However, perhaps you’re reading this and feeling great that you eat your veggies but struggle to get your kids to do the same. If you are a parent, who is simply trying to provide nutritious options to your kids, give these tips a try.

1. Add cheese or butter to enhance flavor and increase the absorption of fat soluble vitamins A, D, E and K. Younger kids like to dip foods, so often pairing with a dip, such as hummus, can increase intake.

2. Try the “rule of 15” — putting a food on the table at least 15 times to see if a child will accept it. Don’t give up after a few attempts. This can indeed be frustrating, but have patience and continue to offer a small portion to expose children to veggies without forcing intake. Often parents feel like it’s their job to just make their children eat something. I suspect most children will always select apple pie over an apple. It is important to set the stage, at an early age, with what is offered. In addition, being a good food model is important. You can’t expect your child to try broccoli, if you make negative comments about its taste, texture or smell.

3. Once a food is accepted, parents should use “food bridges,” finding similarly colored or flavored foods to expand the variety of foods a child will eat. If a child likes pumpkin pie, for instance, try mashed sweet potatoes and then mashed carrots. If a child loves corn, try mixing in a few peas or carrots. Even if a child picks them out, the exposure to the new food is what counts.

4. Allow children to engage, as able. When grocery shopping or offering a snack, ask your child which option they would like to eat (e.g. ask which healthy foods they would prefer, blueberries or strawberries, cucumbers or carrots, etc.). When children are included in more food decisions it can decrease resistance. Include children in age appropriate preparation, as well, for example cutting produce, making a vegetable soup, or selecting produce at the grocery store.

There are various theories about the best time of day to workout. At the personal training studio I own, training sessions start as early as 5:45am and the latest sessions start at 8pm. We have people that get up early and get their workout done first thing in the morning. We also have other people that get it done after work to release the stress of the day.

So which group is getting the better workout?

If you’re an early bird or have too many evening commitments then a morning workout is ideal for you. Here are some benefits to training in the morning.

1. Very few things can get in the way when you workout in the morning. (Except for the snooze button.) Later in the day extra phone calls, meetings and tasks can get in the way of getting your workout done.

2. After a strength or interval training session, your metabolism is elevated for hours after your workout. Enjoy these post exercise benefits while you are awake and active instead of when you are at rest.

3. Exercise will boost your energy. Use the momentum from a morning workout to arrive at work energized, present and focused instead of feeling sluggish because you just got out of bed.

4. Exercise on an empty stomach before breakfast is a great way to burn more body fat. Upon waking, the body is in a fasted state. Without ready available glucose in the bloodstream, the body is forced to use fat as an available fuel source for the workout.

However, some of us need our sleep or need to burn off the steam of a hectic workday. Here are some of the benefits of working out in the evening.

1. Getting enough sleep is crucial for health and recovery. If you have to skimp on regular sleep to get up for an early workout, the benefits of the workout start to diminish.

2. Instead of taking that stress of work home, you hit the gym after work. Even after the worst workdays, exercise will boost your mood. Friends and family will be grateful that you get your workouts (aka therapy session) completed.

3. Often people feel stronger when they workout in the evenings. When performing strength tests people tend to lift heavier during evening workouts. This could be due to the fact that they are more awake or that they have food fuel to utilize during their exercise session.

4. Research shows that you can build more muscle with evening workouts because cortisol levels are lowest in the evening. The result of this will be a higher testosterone to cortisol ratio leading to a less catabolic workout.

So which time of day comes out on top for the best workout time? In my opinion, it’s the time that you can do consistently. It’s the time that works best with your natural energy rhythms, work schedule, and family commitments.

Experiment working out at different times to see what works best for you. When you find the right fit, schedule your workouts on your calendar to build the exercise habit.

“Looking over your medical record, Nancy, I’m a bit concerned about your risk for osteoporosis and hip fracture. It looks like your mom had a hip fracture at age 67. Is that right? ”

“Yes, she did,” Nancy responded. “And her life was never quite the same for the 15 years she lived after that.

“You’re 53 year old. Bone thinning develops over many years. Let’s get you scheduled for a bone scan.”

Two weeks later:

“Your z-score is 1.5, Nancy. This means you’ve got a mild form of osteoporosis called ‘osteopenia.’ Here: This is a prescription for alendronate, what used to be called Fosamax.”

“Aren’t there side-effects with that drug? A friend of mine said that her mom had a leg fracture from it.”

“Well, yes. All prescription drugs have potential side-effects. They’re rare, but they can happen and we can’t predict it. Besides leg fracture, there’s something called jaw osteonecrosis in which the jawbone dies and has to be surgically replaced. But would you rather run the risk of a hip fracture?”

“Before we jump to drugs, aren’t there natural things I could do first?”

(Big sigh.) “You can take calcium, but that only helps a bit. You’ve got to make a choice: Take the drug or risk a hip fracture.”

“I’m going to explore some natural remedies on my own first.”

Nancy’s dialogue with her doctor is fictional but based on similar encounters that occur thousands of times every day nationwide. Identify a problem, prescribe a drug. Natural remedies? “They don’t work.” “I don’t know anything about that.” “None of that is proven.” “I only practice evidence-based medicine.” You’ve probably heard a few of these explanations yourself if you ever question the wisdom of conventional medical care.

Each of Nancy’s fictitious interactions were no more 10 minutes long. If she is like most people, she will have one or two such interactions over the course of a year, unless she develops some acute illness. So she’s got something like 20-30 minutes per year to compress all of her “health” advice into the time allotted. 20-30 minutes per year to discuss bone health, nutrition, blood sugar issues, cholesterol issues, blood pressure, female issues, and all the other facets of health. Perhaps she has developed some chronic gastrointestinal complaints, too, and an odd rash on her elbows, maybe headaches a few times per week that she didn’t have before. Regardless, she’s going to have to make do with those few minutes, likely receiving one or more prescriptions or imaging procedures for each.

Such is the nature of modern healthcare: Provide the minimum interaction, address only a few, perhaps no more than one, problem, then prescribe a drug. This is, more often than not, wrong. Plain wrong. Tragically, awfully, unethically, unnecessarily wrong.

Let’s pick up again with Nancy. Upon learning of her osteopenia and long-term risk for hip fractures of the sort that changed her mom’s life and health irretrievably, Nancy started searching for solutions. Not only did she discover that, yes, there are indeed a number of safe and effective ways to deal with osteopenia. She also learned that such strategies have even been examined in clinical trials, some of the strategies pitted head-to-head with drugs and performed on a par, sometimes better, than prescription drugs. She also found that there are online communities that she could join and discuss her health situation with people all sharing the same health interests. During one such interaction at the start of her effort, when she was still a bit unsure and tentative, a woman she didn’t know but who shared a similar interest in restoring bone health, commented to Nancy, “Don’t sweat it, Nancy. I was in your shoes a little over a year ago. I followed a program for bone health: vitamin D, vitamin K2, magnesium, I made sure that I included leafy green vegetables at least once or twice per day, and I added strength training for a few minutes twice per week. I started with osteoporosis. My most recent bone density test showed that I reversed it completely—it’s entirely normal! So hang in there and be sure to share your questions and concerns with us here.”

THAT is what Cureality is all about. Cureality fills the gap of knowledge in health that is not being provided in a few minute-long medical interaction. Cureality reveals the astounding amount of credible, safe, scientific information that allows you to participate, sometimes take over completely, various aspects of health. You don’t have to fire your doctor; these efforts supplement the information and advice you obtain (or don’t obtain) in the doctor’s office. While critics may sometimes say that this can be dangerous or that misdiagnoses and dangerous treatments might be risked, our experience is the exact opposite: People do better by taking the reins of health themselves, choosing to use the health care system for acute or catastrophic illness—but not necessarily for health.

Our fictional woman, Nancy, returns to her doctor one year later after undergoing a repeat bone scan. The doctor opened her chart, clearly expecting to scold her for her foolhardy and careless attitude. Instead, he was speechless. After a pause, he said, “I don’t know how you did it, but your bone density is now normal, the density of a healthy 30-year old woman. Just continue doing what you’re doing.” He closed the chart and walked out.

Yes: “Just continue what you are doing”—not “Please tell me what you did so that I might learn something new,” or “Where did you learn about such strategies? I knew nothing about this!” Just “do what you’re doing.” Too often, that is the response you get that defines what modern health care has become.

You don’t want that kind of health care. Sure, it’s reassuring to know that the doctor and hospital are there in case you injure yourself or develop pneumonia. But obtain day-to-day health advice of the sort that keeps you slender, keeps blood pressure normal, maintains normal insulin and blood pressure responses, helps keep bowel health ideal, can even be used to reverse conditions such as autoimmune joint pain, diabetes, osteoporosis, or skin rashes, while costing next to nothing and yielding health care benefits for you and your family in multiple areas of health? That is the kind of health care you want.

That’s why we developed Cureality.

For new comers to the Cureality nutrition approach, this question may invariably pop up. For many years, fats and oils, whether classified as good or bad, were demonized because they contain 9 calories per gram. Meaning, they contain more than twice the 4 calories per gram of carbohydrate or protein.

So this familiar logic stated, if you eat less fat, which by default meant more carbohydrate, you would eat fewer calories and lose weight. This misguided logic was based on the assumption that caloric density was the primary reason people either gained or lost weight. The result - obesity rates have climbed and low-fat diet recommendations have proven unsuccessful in thwarting the battle of the bulge.

Why? There are a multitude of reasons, as discussed in the Cureality Diet Track. The following two explanations are important to to avoid needlessly suffering on a low-fat diet.

1) Appetite satiation is drive by insulin response, not calorie density.

Meals that trigger a substantial insulin response trigger increased appetite and fat storage. Carbohydrates, such as whole grain bread, whole wheat waffles, and fruit juice trigger insulin release. Continuous insulin provocation equates to one heck of a time trying to lose weight, as insulin is a fat-storage hormone. In comparison, oils and fats are the least insulin provoking with protein a close second. Consuming adequate fat intake is essential to quench appetite and avoid the insulin surges and crashes that are the result of eating plenty of “healthy whole grains”.

2) Modern wheat increases appetite thereby increasing intake.

Portion control becomes a major challenge because the gliadin protein in modern wheat stimulates appetite to the tune of 400 calories more per day, 365 days per year. That’s a recipe for weight gain, not loss.

The Cureality nutrition approach encourages the generous use of healthy fats and oils to support healthy weight loss and cardiovascular health. These topics are discussed in much more detail in the Cureality Member Forum.

In my previous post I spoke about the close connection between gut health and thyroid health. Of course, as someone who lives with Hashimoto’s Thyroiditis I have a keen interest in anything related to the thyroid.

Just today, I came across an article revealing the 100 most-prescribed drugs in America and was stunned at what drug topped the list with more than 23 million prescriptions in 2013 – levothyroxine – the most commonly prescribed drug for treating hypothyroidism (but not necessarily the best in my opinion).

Some observers have warned about a pending epidemic of thyroid disorders. I believe the revelation of a thyroid drug as the most prescribed drug in America suggests that this epidemic is already a “fait accompli” (that’s French for the more colloquial expression “it’s a done deal!”).

I also believe it is due, in part, to the grim observations of experts like Dr. Davis who warn that we are literally “swimming in a sea” of endocrine disruptors, toxins that disrupt our hormonal glands such as the thyroid, adrenals, pancreas, ovaries, and testes. I would go farther to say we are drowning in that sea. Here are just a few examples of how ubiquitous and pervasive these toxins are.

Bisphenol A (BPA) in plastic containers has gotten a lot of bad press recently yet it still considered by the FDA to be safe in certain applications even though it has been shown to disrupt the sex glands and bind to thyroid receptors.

Triclosan is commonly used in hand-sanitizers and similar applications. Triclosan is known to decrease circulating levels of the thyroid hormone thyroxine (T4).

Polybrominated diphenyl ether (PBDE) is common used to make flame retardant clothing. PBDEs have been shown to disrupt both estrogen and thyroid hormones. The effects of PBDE exposure both in utero and shortly after birth can persist into adulthood.

Perfluorooctanoic acid (PFOA) in Teflon coated pots and pans and even microwave popcorn bags has been detected in the blood of more than 98% of the general US population. PFOA has implicated as both a carcinogen as well as an endocrine disruptor associated with thyroid disruption.

With all these “thyro-toxins” floating about it might not seem you like have a fighting chance to achieve thyroid health. But, the first step is to educate yourself - then take action. It is the essential sequence in what I call “Informed, Self-directed, Healthcare” (ISH).

Now that you have a better understanding of how to navigate the “thryo-toxin minefield” there are also positive steps you can take to stack the odds in favor of a healthy thyroid. If you participate in the Cureality program make certain to check out the Thyroid Health Track for a powerful list of proactive steps you can take.

100% grain elimination is the theme that drives the Cureality nutrition approach. A common mistake made when eliminating grains is replacing wheat-based foods with gluten-free foods. Most gluten-free foods, as they are currently available in the supermarket, are made with rice starch, tapioca starch, cornstarch, and potato flour. These dried pulverized starches generate more insulin and blood sugar surges than wheat. Gluten-free foods made with these undesirable ingredients are free of the appetite stimulating gliadin protein and wheat germ agglutinin, a lectin protein unique to wheat that causes direct intestinal damage. However, at best they can be referred to as “less bad” or unwelcome additions to the diet. Increasing your intake of these junk carbohydrates is a recipe for weight gain, inflammation and sky high blood sugar.

When removing grains from the diet, the goal is to replace them with truly healthy alternatives that do not contribute to negative health consequences. There are several reasonable substitutions available that allow your favorite sauce and protein combos to shine in tasty pasta-like dishes. People following the Cureality nutrition approach frequently comment that they do not miss “real” pasta because of the available healthy replacements they have learned about and incorporated into their lifestyle.

Our nutritionist, Lisa G., is the champion at helping navigate this lifestyle. In this video, she demonstrates how to prepare spaghetti squash, which can be used to replace wheat-based pasta. In another video zucchini noodles are the star. Homemade meatballs, a zesty tomato sauce and zucchini “pasta” combine for a delicious meal. Who needs grains when you can enjoy meals that support increased energy and less joint pain?

Summer vacation is right around the corner. The temptation to deviate from your normal healthy eating habits may occur… but resist. So how in the world do you continue to eat The Cureality way when you're traveling internationally? Let me tell you how I do it. I would also like to add I am allergic to dairy and I avoid all wheat containing foods. This has been my way of life for years and actually is extremely simple for me to manage while away from my own kitchen.

I decided to pay Italy a visit. I knew I would be overwhelmed with wonderfully fresh smelling bakery, pasta, cheese, gelato, and pizza. All foods I either can't consume due to my dairy allergy or foods I choose to avoid because of their health effects.

I was correct in my food assessment: the grains, bakery, and gelato were in every nook and cranny I encountered. Food choices can be difficult while traveling but I ask numerous questions regarding ingredients and I am certainly not afraid to swap out french fries for grilled vegetables.

Here's what I did the first few days on vacation with my diet routine to minimize dietary booby traps:

Day 1:

Breakfast, Hmmmm….Italians like their bakery. WOW. Tough when most of the foods being served are grains and eggs with dairy mixed in. I had two hard boiled eggs, tomatoes, sausage and espresso.

Lunch: Arugula lettuce topped with a chicken breast, roasted peppers and tomatoes. A side of salmon and lots and lots of olive oil on top. Very tasty and filling with the olive oil.

Dinner: Hamburger (no bun) with tomato, mayo, lettuce topped with a mountain of sauteed spinach. Water and yes…Italian wine found it's place at the table.

Day 2:

Breakfast: I devoured two hard boiled eggs with lettuce, cucumbers, shredded carrots, tomato and pineapple slices. Two cafe Americanos and water.

Lunch: Lunch was spectacular: Beef tips, arugula, lettuce, shredded carrots, tomatoes, olive oil and raw salmon. Yes, I mixed it all together and it was fabulous. Plenty of water with the "frizzle."

Dinner: I'll be honest: I had a difficult time with this meal due to our location and choice of foods, but I managed. Another hamburger with no bun, salad with mixed vegetables, and a few potato wedges. Wine and water.

Day 3:

Breakfast: Hardboiled eggs were getting old. Nonetheless, I had two of them chopped with tomato. Deli meat--Italians love their deli meat as well. Cafe Americano and water.

Lunch: Seafood salad-shrimp, octopus and squid mixed with argulua, fresh tomatoes, cucumbers and olive oil. Water.

Dinner: One hefty salad with shrimp, pear slices, ginger, tomatoes, avocado and olive oil. Wine and water.

Day 4:
Breakfast: Scrabbled eggs/sauage and pineapple slices. Cafe Americano and plenty of water.

Lunch/Dinner: I had to combine these two meals today. I had a delicious meal of curried shrimp (I made sure there was no dairy in the curry sauce) and a very large plate of grilled vegetables. Wine and water.

My diet may not be the most lavish to some but I enjoy my choices. I'm confident I will have no troubles with the remainder of my vacation. I haven't eaten wheat for a number of years so I don't experience the craving for bakery, pasta, or pizza. Dairy, I simply have to avoid, because I truly experience ill-effects from consuming it. My experience with travel and food choices have always worked in my favor. Ask questions and resist putting on that 5-10 pounds of vacation weight.

Ciao-Ciao~

There's a $22 billion industry based on treating LDL cholesterol, a fictitious number.

LDL cholesterol is calculated from the following equation:

LDL cholesterol = Total cholesterol - HDL cholesterol - triglycerides/5

So when your doctor tells you that your LDL cholesterol is X, 99% of the time it has been calculated. This is based on the empiric calculation developed by Dr. Friedwald in the 1960s. Back then, it was a reasonable solution, just like bacon and eggs was a reasonable breakfast and a '62 Rambler was a reasonable automobile.

One of the problems with Dr. Friedewald's calculation is that the lower HDL cholesterol, the less accurate LDL cholesterol becomes. If it were just a few points, so what? But what if it were commonly 50 to 100 mg/dl inaccurate? In other words, your doctor tells you that your LDL is 120 mg/dl, but the real number is somewhere between 170 and 220 mg/dl. Does this happen?

You bet it does. In my experience, it is an everyday event. In fact, I'm actually surprised when the Friedewald calculated LDL closely approximates true LDL--it's the exception.

Dr. Friedewald would likely have explained that, when applied to a large population of, say, 10,000 people, calculated LDL is a good representation of true LDL. However, just like saying that the average weight for an American woman is 176 lbs (that's true, by the way), does that mean if you weigh 125 lbs that you are "off" by 41 lbs? No, but it shows how you cannot apply the statistical observations made in large populations to a single individual.

The lower HDL goes, the more inaccurate LDL becomes. This would be acceptable if most HDLs still permitted reasonable estimation of LDL--but it does not. LDL begins to become significantly inaccurate with HDL below 60 mg/dl.

How to get around this antiquated formula? In order of most accurate to least accurate:

--LDL particle number (NMR)--the most accurate by far.

--Apoprotein B--available in most laboratories.

--"Direct" LDL

--Non-HDL--i.e., the calculation of total cholesterol minus HDL. But it's still a calculated with built-in flaws.

--LDL by Friedewald calculation.

My personal view: you need to get an NMR if you want to know what your LDL truly is. A month of Lipitor costs around $80-120. A basic NMR costs less than $90. It's a relative bargain.

Faye was clearly frustrated.

At age 52, she was having chest pains every day. A CT heart scan showed a score of zero. A CT coronary angiogram showed no plaque whatsoever.

"Everything went downhill when my menopause started. I gained weight, I started to have chest pains, my blood pressure went up, my cholesterol shot up."

She saw three physicians, none of whom shed much light on the situation. They ran through the predictable sequence of (horse, not human) estrogens, anti-depressants, suggestions for psychological counseling.

But we checked Faye for lipoprotein(a), which she proved to have at a high level of 182 nmol/l. This explained a lot.

A curious and predictable set of phenomenon occur to females with Lp(a) proceeding through the menopause. As estrogen recedes:

--Lp(a) levels rise dramatically.

--Blood pressure goes up, sometimes creating severe hypertension by mid- to late-50s.

--Chest pain can develop, presumably due to "endothelial dysfunction" or "microvascular angina", both representing abnormal coronary artery constriction facilitated by worsening expression of Lp(a).

All too often, these phenomena get dismissed as simply part of the menopausal package, when they are, in fact, important facets of this very important genetic pattern that confers high risk for heart disease.

If any of this rings familiar for you or a loved one, think Lp(a). Though Faye hadn't yet developed any measurable coronary plaque by her CT heart scan score, it was likely on its way, given the surge in Lp(a) expression as menopause unfolded--unless its recognized and appropriate preventive action taken.

I've talked about this before, but I need to periodically remind everybody:
Vitamin D must be an oil-based capsule, a gel-cap, not a tablet.

Lisa is one of early success stories: a heart scan score of 447 in her early 40's, modest reduction of CT heart scan score three years ago.

However, Lisa had a difficult time locating oil-based vitamin D. There has, in fact, been a national run on vitamin D and I'm told that even manufacturers are scrambling to keep up with the booming demand. So, she bought tablets instead and was taking 3000 units per day.

She came in for a routine check. Lisa's 25-OH-vitamin D3: 17 ng/ml, signifying severe deficiency, the same as if she were taking nothing at all. (Recall that we aim for 50 ng/ml.)

In other words, vitamin D tablets do not work. It is shameful. I see numerous women taking calcium tablets with D--the vitamin D does not work. I've actually seen blood levels of zero on these preparations.

You may have to look, but if you want to enjoy the extraordinary benefits of vitamin D replacement, it must be an oil-based capsule. Carlson's and Vitamin Shoppe have excellent prepartions. They raise blood levels substantially and consistently, and they're inexpensive. We pay $5.99 for a bottle of 120 capsules.

What if vitamin D cost $200 rather than $2?

In other words, what if cholecalciferol, or vitamin D3, was a patent-protectable agent that would sell for an extravagant price, just like a drug?

Vitamin D would be the hot topic. There would be TV ads run during Oprah, slick magazine two-page spreads with experts touting its outsized benefits, insurance companies would battle over how much your copay should be.

The manufacturer would host large fancy symposia to educate physicians on how wonderful vitamin D is for treatment of numerous conditions, complete with dinner, a show, and gifts. They would hire expert speakers to speak, scientists to have articles ghost-written, give out knick knacks with the brand label inscribed--just like Lipitor, Actos, Vytorin, ReoPro, Plavix . . .

After all, what other "drug" substantially increases bone density (up to 20% in adult females), enhances insulin responses 30% (equivalent to the TZD drugs, Actos and Avandia), and slashes colon cancer risk?

But it's not a drug. That is both vitamin D's strength and its weakness. It's a strong point because it's natural, phenomenally helpful across a variety of conditions, and inexpensive. It is also a weakness because, at $2 a month, no one is raking in the $12 billion annually that Pfizer makes for Lipitor that allows it to fund an enormous marketing campaign.

Vitamin D is a "discovery" of huge importance for health, including making reductions of CT heart scan scores far more likely for more people. And it comes without a prescription.

Fanatic Cook has posted an excellent summary on the recent negative attention cast on garlic preparations, at least for LDL cholesterol reduction.

Go to http://fanaticcook.blogspot.com to view.

I think Fanatic Cook is right--despite the lack of LDL reducing effects, it doesn't necessarily mean no benefit whatsoever. Anti-coagulation and anti-inflammatory effects, in particular, are well proven.

I do think, however, that it argues more in favor of sticking to whole cloves, rather than supplements. The benefits are also likely small. I would view garlic as a soft advantage for your plaque control program. You can do fine without it. You might do slightly better with it.

Most hospitals maintain the "Saint _____" in their names, despite many having little or nothing to do with the church.

Out of 15 hospitals in my area, 13 are named after saints.

In my view, a more honest name would be something like "ABC Medical Enterprises, Inc." The profit motive, aggressive marketing tactics, and high CEO salaries would make better sense then. The trend to convert practicing physicians from professionals acting on behalf of patient welfare into paid employees would also be clearer.

Imagine Walmart were to change its name to "St. Mary's Emporium" Would it modify your perception of their business? I think it would. It would cause many people to believe that maybe their work was, at least in part, charitable and being done for the public welfare. But Walmart makes such pretense--they are in business for profit, just like all businesses.

It's time for the pretense to be dropped. Hospitals are cut-throat profit-seeking operations, operating under the guise of charitable, tax-free institutions. It's the farthest thing from the truth.

You can always count on Dr. John Cannell for unique perspectives on vitamin D. I reprint here his unfailingly entertaining and informative Vitamin D Newsletter on whether vitamin D replacement enhances physical performance.

The whole vitamin D "discovery" sometimes worries me. Vitamin D has proven to be an unbelievable, remarkable, dramatic boon to health, including facilitation in dropping CT heart scan scores. Yet the answer was always right in front of us. It worries me that you and I might have the answer to important questions right within our grasp all along--but don't know it. What if the same were true, say, for cancer? That is, a profound answer is right there, but our eyes just pass right over it.

Anyway, we should all keep our eyes open and perhaps you and I will continue to identify the most powerful tools available that return control over heart disease to us and take it away from the perverse, procedural hospital formula that still reigns.

If you haven't done so already, be sure to visit Dr. Cannell's website, www.vitamindcouncil.com.

Peak Athletic Performance and Vitamin D

"No way doc." I had just finished telling my patient about the benefits of vitamin D, telling him he should take 4,000 IU per day, using all the techniques I had learned in 30 years of medical practice to convince someone proper treatment is important. But, he knew the U.S. government said he only needed 200 IU per day, not 4,000. He also knew the official Upper Limit was 2,000 IU a day. "What are you trying to do doc, kill me?" I told him his 25(OH)-vitamin D blood test was low, only 13 ng/ml. He had read about that too, in a medical textbook, where it said normal levels are between 10 and 40 ng/ml. "I'm fine doc;" adding "Are you in the vitamin business?" I explained I was not; that the government used outdated values; that recent studies indicate ideal 25(OH)D levels are about 50 ng/ml; and that they indicated that he needed about 4,000 IU per day to get his level up to 50. "No thanks doc, I'm fine."

So I tried a different tact. I brought him copies of recent press articles. "Look," I said, "look at these." Science News called vitamin D the Antibiotic Vitamin. The Independent in England says vitamin D explains why people die from influenza in the winter, and not the summer. U.S. News and World Report says almost everyone needs more. Newsweek says it prevents cancer and helps fight infection. In four different recent reports, United Press International says that: it reduces falls in the elderly, many pregnant women are deficient , it reduces stress fractures, and that it helps heals wounds.

He glanced at the articles, showing a little interest in stress fractures. Then he told me what he was really thinking. "Look doc, all this stuff may be important to old guys like you. I'm 22. All I care about are girls and sports. When I get older, maybe I'll think about it. I'm too young to worry about it. I'm in great condition." I couldn't argue. He was in good health and a very good basketball player, playing several hours every day, always on indoor courts.

What could I do to open his eyes? As an African American, his risk of early death was very high, although the risk for blacks doesn't start to dramatically increase until their 40's and 50's. Like all young people, he saw himself as forever young. The U.S. government was no help, relying on a ten-year-old report from the Institute of Medicine that is full of misinformation.

I tired to tell him that the 200 IU per day the U.S. government recommends for 20-year-olds is to prevent bone disease, not to treat low vitamin D levels like his. I pointed out the U.S. government's official current Upper Limit of 2,000 IU/day is the same for a 300 pound adult as it is for a 25 pound toddler. That is, the government says it's safe for a one-year-old, 25-pound, child to take 2,000 IU per day but it's not safe for a 30-year old, 300-pound, adult to take 2,000 and one IU a day. I mean, whoever thought up these Upper Limits must have left their thinking caps at home. Nevertheless, nothing worked. My vitamin D deficient patient was not interested in taking any vitamin D.

What are young men interested in? I remembered that he had told me: "Sex and sports." Two years ago I had researched the medical literature looking for any evidence vitamin D enhanced sexual performance. Absolutely nothing. That would have been nice. Can you imagine the interest?

Then I remembered that several readers had written to ask me if vitamin D could possibly improve their athletic performance? They told me that after taking 2,000 to 5,000 IU per day for several months, they seemed just a little faster, a little stronger, maybe had a little better balance and timing. A pianist had written to tell me she even played a better piano, her fingers moved over the keys more effortlessly! Was vitamin D responsible for these subtle changes or was it a placebo effect? That is, did readers just think their athletic performance improved because they knew vitamin D was a steroid hormone precursor (hormone, from the Greek, meaning "to set in motion")?

The active form of vitamin D is a steroid (actually a seco-steroid) in the same way that testosterone is a steroid and vitamin D is a hormone in the same way that growth hormone is a hormone. Steroid hormones are substances made from cholesterol, which circulate in the body, and work at distant sites by "setting in motion" genetic protein transcription. That is, both vitamin D and testosterone regulate your genome, the stuff of life. While testosterone is a sex steroid hormone, vitamin D is a pleomorphic (multiple function) steroid hormone.

All of a sudden, it didn't seem so silly. Certainly steroids can improve athletic performance although they can be quite dangerous. In addition, few people are deficient in growth hormone or testosterone, so when athletes take sex steroids or growth hormone they are cheating, or doping. The case with vitamin D is quite different because natural vitamin D levels are about 50 ng/ml and, since almost no one has such levels, extra vitamin D is not doping, it's just good treatment. I decided to exhaustively research the medical literature on vitamin D and athletic performance. It took me over a year.

To my surprise, I discovered that there are five totally independent bodies of research that all converge on an inescapable conclusion: vitamin D will improve athletic performance in vitamin D deficient people (and that includes most people). Even more interesting is who published this literature, and when. Are you old enough to remember when the Germans and Russians won every Olympics in the 60's and 70's? Well, it turns out that the most convincing evidence that vitamin D improves athletic performance was published in old German and Russian medical literature.

With the help of my wife and mother-in-law, both of whom are Russian, and with the help of Marc Sorenson, whose book Solar Power is a must read, I finally was able to look at translations of much of the old Russian and German literature. When one combines that old literature with the modern English language literature on neuromuscular performance, the conclusion is inescapable. The readers who wrote me are right.

If you are vitamin D deficient, the medical literature indicates that the right amount of vitamin D will make you faster, stronger, improve your balance and timing, etc. How much it will improve your athletic ability depends on how deficient you are to begin with. How good an athlete you will be depends on your innate ability, training, and dedication. However, peak athletic performance also depends upon the neuromuscular cells in your body and brain having unfettered access to the steroid hormone, activated vitamin D. In addition, how much activated vitamin D is available to your brain, muscle, and nerves depends on having ideal levels of vitamin D in your blood - about 50 ng/ml, to be precise.

Why would I write about such a frivolous topic like peak athletic performance when cancer patients all across this land are dying vitamin D deficient? Like many vitamin D advocates, I have been disappointed that the medical profession and the public don't seem to care about vitamin D. Maybe people, like my young basketball player, will care if it makes better athletes. So, Hey! You jocks! Listen up! I'm talking speed, balance, choice reaction time, muscle mass, muscle strength, squats, reps, etc. Important stuff. Here's the Vitamin D Council's first ever sports quiz.

1. Vitamin D-producing UVB radiation improves athletic performance and may have been widely practiced by German and Russian Olympic athletes in the 1960's and 70's.

True. I found tantalizing evidence the Russians and especially the Germans were on to this during the 60's and 70's when those two nations took turns placing number one and number two in the Olympics every year?

For example, in 1938, Russian researchers reported that a course of ultraviolet irradiations improved speed in the 100-meter dash in college students compared to matched controls, both groups undergoing daily training. Average 100-meter dash times decreased from 13.51 seconds to 13.28 seconds in the non-irradiated controls, but from 13.63 seconds to 12.62 seconds in the irradiated students. Here we see training improved times but training and irradiation improved times much more. Obviously, irradiation or vitamin D would not render the same magnitude of improvements in world-class sprinters, but they would be happy with a few milliseconds.

Gorkin Z, Gorkin MJ, Teslenko NE. [The effect of ultraviolet irradiation upon training for 100m sprint.] The Journal of Physiology of the USSR [Fiziol, z. (RSSR)] 1938; 25: 695-701. (In Russian)

If you want to know what early German thinking was on this, read this summation of the German literature:

"It is a well-known fact that physical performance can be increased through ultra-violet irradiation. In 1927, a heated argument arose after the decision by the German Swimmers' Association to use the sunlamp as an artificial aid, constituting an athletic unfairness, doping, so to speak. In 1926, Rancken had already reported the improving effect of sunlamp irradiation on muscle work with the hand-dynamo-graph. Heib observed an improvement in swimming times after repeated irradiations. In thorough experiments, Backmund showed that a substantial increase in muscle activity happens after radiation of larger portions of the body with an artificial sunlamp; that this performance increase is not caused through local - direct or indirect - effects on the musculature, but through a general effect. This general effect, triggered by ultra-violet irradiation, is caused by a systemic effect on the nervous system." (p. 17)

Parade GW, Otto H. Die beeinflussung der leistungsfahigkeit durch Hohensonnenbestrahlung. Zeitschrift fur Klinische Medizin (Z Klin Med),1940;137:17-21 [In German]

In 1945, two Americans measured the cardiovascular fitness and muscular endurance of 11 male Illinois subjects undergoing training in an indoor physical education class, comparing them to 10 matched controls. Both groups underwent similar physical training. Treatment consisted of ultraviolet irradiation, given in the nude, up to two minutes per session, three times per week, for ten weeks in the late fall and winter. After ten weeks, the treatment group had a 19% standard score gain in cardiovascular fitness compare to a 2% improvement in the control students. To regular readers of this newsletter, it should come as no surprise that the un-irradiated control group reported twice as many viral respiratory infections as the treatment group.

Allen R, Cureton T. Effects of Ultraviolet Radiation on Physical Fitness. Arch Phys Med 1945: 10: 641-44.

In 1952, the German sports medicine researcher, Spellerberg, reported on the effects of wholesale irradiation of athletes studying and training at the Sports College of Cologne - including many elite athletes - with a "central sun lamp." He irradiated the athletes in their bathing suits, on both sides of their bodies, for up to ten minutes, twice a week, for 6 weeks. He reported a "convincing effect" on athletic performance and a 50% reduction in sports injuries. Results were particularly impressive for swimmers, soccer, handball, hockey, and tennis players, as well as for boxers and most track and field athletes. He reported that irradiation leading to burns, further irradiation of athletes having achieved peak performance, and irradiation within 24 hours of competition, all impaired athletic performance. Their results were so convincing, the Sports College of Cologne officially notified the "national German and International Olympic committee." (p. 570)

Spellerberg AE. [Increase of athletic effectiveness by systematic ultraviolet irradiation.] Strahlentherapie 1952; 88: 567-70. [In German]

In 1952, Ronge exposed 120 German schoolchildren to UV lights installed in classrooms and compared them to 120 un-irradiated control children. Over a two-year period - excluding summer vacations - he tested both groups with a series of six cardiovascular fitness tests using a bike ergometer. Un-irradiated children showed a distinct seasonality in fitness, with the highest values right after summer break and the lowest values in the spring. Treated children showed no seasonal differences in physical performance. Differences in work performance between the irradiated and un-irradiated children were most conspicuous in the spring with 56% difference between the two groups. In a final experiment, he gave 30 children in the control classrooms 6.25 mg (250,000 IU) of vitamin D as a single dose in February and found their performance had "increased considerably," one month later but did not report the actual numbers. He concluded that vitamin D, either as a supplement or induced via UV irradiation, improved physical performance.

Ronge HE. [Increase of physical effectiveness by systematic ultraviolet irradiation.] Strahlentherapie 1952; 88: 563-6. [In German]

In 1954, another researcher, at the Max-Planck Institute for Industrial Physiology in Dortmund, Germany, administered three different wavelengths of UV light over 8 weeks to university students. He found that ultraviolet light in the vitamin D-producing UVB range was consistently effective in reducing resting pulse, lowering the basal metabolic rate, and increasing athletic performance. UVA had no effect; interestingly, artificial UVC irradiation (the atmosphere normally completely filters out UVC radiation and thus it's not naturally present on earth) also gave some positive results.

Lehmann G. [Significance of certain wave lengths for increased efficacy of ultraviolet irradiation.] Strahlentherapie. 1954 Nov;95(3):447-53. [In German]

In 1956, Hettinger and Seidel irradiated seven subjects in two different experiments: athletic performance on bike-ergometers and forearm muscle strength. They found that UV radiation induced a significant improvement in both muscle strength and athletic performance.

Hettinger T, Seidl E. [Ultraviolet irradiation and trainability of musculature.] Internationale Zeitschrift für angewandte Physiologie, einschliesslich Arbeitsphysiologie 1956; 16: 177-83. [In German]

Another German researcher, at the Institute for Medical Physics and Biophysics at the University of Gottiingen, studied reaction times (the time needed to recognize a light and switch it off) during October and November in a series of controlled experiments on 16 children and an unspecified number of adults. He first controlled for practice effects (getting better by practicing) and then administered nine full-body UV radiation treatments over three weeks to the two treatment groups, using placebo radiation in the two control groups. UV radiation improved choice reaction time by 25% in children and 20% in adults while reaction time worsened in controls. The improvements in the irradiated groups peaked at the end of the three weeks of UV treatments and reverted to baseline levels three weeks later. In the two control groups, he found distinctly improved reaction times in the sunnier months.

Sigmund R. [Effect of ultraviolet rays on reaction time in man.] Strahlentherapie. 1956; 101: 623-9. [In German]

The next study threw me because it was very well conducted, meticulously designed, and completely negative. In 1963, Berven reported on the effects of ultraviolet irradiation and vitamin D supplementation in a group of 30 Stockholm schoolchildren, aged 10 -11, comparing them to appropriate controls. He found no seasonality of fitness in the control group and no effect from either irradiation or two different vitamin D supplementation protocols (1500 IU of cholecalciferol daily for two months and a single dose of 400,000 IU of ergocalciferol) on performance on a bike ergometer.

Berven H. The physical working capacity of healthy children; seasonal variations and effect of ultraviolet irradiation and vitamin-D supply. Acta paediatrica. Supplementum 1963; 148: 1-22.

However, two things were not right and got me thinking. One, Berven found no seasonality of physical fitness and was the only author who found no such seasonal variations in athletic performance. Second, he found no effect from irradiation, again, the only author. Then I realized he was working with Swedish children in the late 1950's. Supplementation of children with high doses of vitamin D - often as cod liver oil - was routine in Scandinavia in the past, particularly in children. For example, in neighboring Finland, the official recommended daily dose of vitamin D for children - including infants - was 4,000 IU per day until 1964, when authorities reduced it to 2,000 IU/day. (That's right, you read that correctly, 4,000 IU per day for infants, which is too much by the way.)

In 1975, Finnish authorities reduced it to 1,000 IU per day, and, in 1992, to 400 IU per day. I emailed Professor Elina Hypponen who confirmed that the Swedish recommendations were similar to the Finnish ones. Therefore, it seems highly unlikely that many of Berven's Swedish children, studied in 1958 and 1959, all from "families with a good standard of living," were vitamin D deficient. Therefore, this study showed that vitamin D will not improve athletic ability in vitamin D replete people. That's very important because it indicates more is not necessarily better. More is only better if you are not taking enough.

Hypponen E, et al. Intake of vitamin D and risk of type 1 diabetes: a birth-cohort study. Lancet. 2001 Nov 3;358(9292):1500-3.

In the 1960's, three American researchers conducted experiments with university students. Rosentswieg studied the effects of a single six-minute dose of UV light on each side of the trunk in 23 college women, recording changes in various tests of muscle strength at one and five hours. He found a trend towards significance after five hours in white but not African American students. In 1968, Cheatum found that a six-minute administration of UV light, on each side of the trunk, increased the speed of 15 college women in the 30-yard dash. In 1969, Rosentswieg found a six-minute dose of UV light, on each side of the trunk, finding improved performance on a bicycle ergometer in college women. However, unlike the Germans and Russians, I could find no evidence that any of these American findings interested any American professionals involved in the care or training of athletes.

2. Athletic performance peaks in the summer when vitamin D levels peak, and is at its lowest in the winter when vitamin D levels are at their lowest.

A. True
B. False

True. The studies below - all I could find in the literature - show tests of physical performance peak in the summer, when vitamin D levels peak, start to decline in early autumn, as vitamin D levels decline, and athletic performance reaches its lowest point in late winter, when vitamin D levels bottom out. However, it is reasonable to assume that any associations between athletic performance and summer season may be due to "reverse causation." That is, improved athletic performance in the summer might be secondary to increased outdoor physical and recreational activity in the warmer weather with an indoor sedentary lifestyle during the colder months. Maybe people have better athletic ability in the summer because they exercise more. If that is true - and using the same logic - athletic performance should not begin to decline until late autumn, because at most temperate latitudes early fall weather is ideal for outdoor physical activities.

However, some of the studies below controlled for seasonal variations in time spent exercising. Furthermore, besides a consistent positive association of summer season with improved athletic performance, the below studies found an abrupt - and unexplained - reduction in athletic performance beginning in the early fall - when vitamin D levels decline - but when the weather is ideal for outdoor activities.

For example, in 1956, German researchers found a distinct seasonal variation in the trainability of musculature, studying wrist flexor strength in 21 German subjects undergoing daily training. They found highly significant seasonal differences with peak performance during the later part of the summer, nadirs in the winter, and an unexplained sharp autumn decline beginning in October.

Hettinger T, Muller EA. Seasonal course of trainability of musculature. Int Z Angew Physiol. 1956;16(2):90-4.

A study of Polish pilots and crew found physical fitness and tolerance to hypoxia were highest in the late summer with an unexplained sharp decline starting in September. The authors hypothesized that seasonal variations in an unidentified hormone best explained their results.

Kwarecki K, Golec L, Klossowski M, Zuzewicz K. Circannual rhythms of physical fitness and tolerance of hypoxic hypoxia. Acta Physiol Pol. 1981 Nov-Dec;32(6):629-36.

Cumulative work ability among 1,835 mainly sedentary Norwegian men during bicycle exercise tests showed an August peak, a sharp decline starting in the autumn, and a wintertime nadir. There were no seasonal changes in body weights, as might be expected if more caloric-demanding recreational activity during the sunnier months explained their results.

Erikssen J, Rodahl K. Seasonal variation in work performance and heart rate response to exercise. A study of 1,835 middle-aged men. Eur J Appl Physiol Occup Physiol. 1979 Oct;42(2):133-40.

Koch and Raschka reviewed the mostly German literature on the seasonality of physical performance, discussing studies indicating that muscle strength and stamina peak in the late summer. The authors then attempted to control for seasonal variations in the time spent exercising by instituting a controlled yearlong training regimen, beginning in December. The training regimen consisted of at least 20 push-ups per day and 2 or 3 long-distances races per week for the entire year. They found the both the number of push-ups and muscle strength peaked in late summer followed by a rapid decline in the fall, and a nadir in the winter, despite continued training. They concluded that seasonal variations in an unidentified hormone best explained their results. In addition, by now we all know that vitamin D is a seasonal hormone, and a steroid hormone precursor to boot.

Koch H, Raschka C. Circannual period of physical performance analysed by means of standard cosinor analysis: a case report. Rom J Physiol. 2000 Jan-Dec;37(1-4):51-8.

3. Vitamin D has direct muscle-building (anabolic) effects.

A. True
B. False

True, but only in vitamin D deficient subjects. Both animal and human studies have found that vitamin D directly affects muscle. That is, vitamin D increases muscle mass.

For example, Birge and Haddad found that vitamin D caused new protein synthesis in rat muscle.

Birge SJ, Haddad JG. 25-hydroxycholecalciferol stimulation of muscle metabolism. J Clin Invest. 1975 Nov;56(5):1100-7.

What about humans? In 1981, Young performed muscle biopsies on 12 severely vitamin D deficient patients before and after vitamin D treatment. They found type-II (fast-twitch) muscle fibers were small before treatment and significantly enlarged after treatment. Sorensen performed muscle biopsies on eleven older patients with osteoporosis before and after treatment with vitamin D. The percentage and area of fast twitch fibers increased significantly after treatment, despite the lack of any physical training.

Young A, Edwards R, Jones D, Brenton D. Quadriceps muscle strength and fibre size during treatment of osteomalacia. In: Stokes IAF (ed) Mechanical factors and the skeleton. 1981. pp 137-145.

Sorensen OH, Lund B, Saltin B, Lund B, Andersen RB, Hjorth L, Melsen F, Mosekilde L. Myopathy in bone loss of ageing: improvement by treatment with 1 alpha-hydroxycholecalciferol and calcium. Clin Sci (Lond). 1979 Feb;56(2):157-61.

Sato reported that two years of treatment with 1,000 IU of vitamin D per day significantly increased muscle strength, doubled the mean diameter, and tripled the percentage of fast-twitch muscle fibers, in the functional limbs of 48 severely vitamin D deficient elderly stroke patients. The placebo control group suffered declines in muscle strength, and in the size and percentage of fast-twitch muscle fibers.

Sato Y, Iwamoto J, Kanoko T, Satoh K. Low-Dose Vitamin D Prevents Muscular Atrophy and Reduces Falls and Hip Fractures in Women after Stroke: A Randomized Controlled Trial. Cerebrovasc Dis. 2005 Jul 27;20(3):187-192 [Epub ahead of print]

These studies clearly show that vitamin D when administered to vitamin D deficient people stimulates the growth and number of those muscle fibers critical to athletic ability, type-2, or "fast twitch," muscle fibers.

4. Many studies have found direct associations between physical performance and vitamin D levels. That is, the higher your vitamin D level, the better your athletic performance.

A. True
B. False

True. I found 13 positive studies of associations between vitamin D levels and various parameters of neuromuscular performance. However, they were all in old people. Of course, old people can be athletes too. Furthermore, age differences in physiology and pharmacology are quantitative, not qualitative. That is, what is true in old people will be true in young people, although the magnitude might be different. Higher vitamin D levels are associated with a wide variety of athletic performance but appear to have the strongest associations with balance, timing, and timed tests of physical performance.

The three largest studies had more than 7,000 elderly subjects. All found evidence of a vitamin D threshold of between 30 - 50 ng/ml, above which further improvements in athletic performance were not seen. Wicherts and her colleagues found a linear correlation between vitamin D and neuromuscular performance; scores were 78% better for those with vitamin D levels greater than 30 ng/ml compared to those with levels less than10 ng/ml.

Wicherts IS, et al. Vitamin D status predicts physical performance and its decline in older persons. J Clin Endocrinol Metab. 2007 Mar 6; [Epub ahead of print]

Professor Heike Bischoff-Ferrari, now in Switzerland, did the largest study. She and her colleagues found a strong positive correlation and suggestion of a U-shaped curve with athletic performance on one test peaking with vitamin D levels of 50 ng/ml but deteriorating at higher levels. It is interesting to speculate that levels around 50 ng/ml may be optimal for athletic performance as such levels are common in humans living in a "natural" state of sun-exposure, such as lifeguards or tropical farmers.

Interestingly, all three studies that looked for an association between mental abilities and vitamin D levels found one. A fourth study, unrelated to athletic function, also found an association. The obvious explanation for these findings is that cognitively impaired patients do not go outdoors as often as higher functioning patients and thus have lower vitamin D levels. However, Dhesi found the association after excluding all but mildly demented patients, making such an explanation more difficult. Flicker and - more recently - Przybelski and Binkley, found the association after controlling for outdoor activities, raising the possibility that the association of vitamin D levels with cognitive abilities is casual. Both the vitamin D receptor and the enzyme necessary to activate vitamin D are present in a wide-variety of human brain tissue. If vitamin D deficiency impairs cognitive abilities, it is likely that such deficiencies will also impair the brain's ability to process the complex circuits needed for peak athletic performance.

There can be no doubt that higher vitamin D levels are associated with improved athletic performance in the elderly. From what we know of physiology and pharmacology, the same associations should hold true in young people, including young athletes.

5. Numerous studies have found that vitamin D improves physical performance.

A. True
B. False.

True, but, again, most all the studies are in old persons, not young ones, and none of the studies are in world-class athletes. However, there is no medical reason why vitamin D would improve the athletic performance of vitamin D deficient old people but not vitamin D deficient young ones. Eleven studies found vitamin D improved physical performance, mainly on measures of balance and reaction time. The one study of younger subjects showed dramatic physical performance effects in 55 severely vitamin D deficient women.

In summary, five converging - but totally separate - lines of scientific evidence leave little doubt that vitamin D improves athletic performance. (I actually left out a sixth line of evidence, something a little more complicated, studies of muscle strength and vitamin D receptor polymorphisms; the two studies I could find were both positive.) Anyway, the scientific evidence that UVB radiation, either from the sun or from sunbeds, will improve athletic performance is overwhelming and the mechanism is almost certainly vitamin D production. Peak athletic performance will probably occur with 25(OH)D levels of about 50 ng/ml, whether from sun, sunbeds, or supplements.

All that is missing is a big-time professional or college team identifying and then treating their elite athletes who are vitamin D deficient. Can you imagine what such performance-enhancing effects would do for basketball players, most of who are African American and who practice and play indoors all winter? Or gymnasts? Or weight lifters?

However, a word of caution. The above studies suggest that taking too much vitamin D (more than 5,000 IU per day) may actually worsen athletic performance. Take the right amount, not all you can swallow. Take enough to keep your 25(OH)D levels around 50 ng/ml, year round. Easier yet, regularly use the sun in the summer and sunbeds in the winter - with care not to burn. Once a week should be about right.

When you think about it, none of this should surprise anyone. Every body builder knows that steroid hormones can improve athletic performance, certainly increase muscle mass. Barry Bonds knows they increase timing and power. Moreover, activated vitamin D is as potent a steroid hormone as exists in the human body. However, unlike other steroids, levels of activated vitamin D in muscle and nerve tissue are primarily regulated by sun exposure. That's right, the rate-limiting step for the cellular function (autocrine) of activated vitamin D is under your control. It depends on how much you put in your both or go into the sun. It's ironic that many athletes now avoid the sun, organized baseball is even promoting sun avoidance and sunblocks. The ancient Greeks knew better; they had there elite athletes train on the beach and in the nude.

The medical literature indicates vitamin D levels of about 50 ng/ml are associated with peak athletic performance. Of course, recent studies show such levels are ideal for preventing cancer, diabetes, hypertension, influenza, multiple sclerosis, major depression, cognitive impairments, etc. But who cares about all that disease stuff old people get, we're talking about something really important: speed, balance, reaction time, muscle mass, muscle strength, squats, reps, etc. And guess who's now taking 4,000 IU/day? Yes he is, and he tells me his timing is better, he can jump a little higher, run a little faster, and the ball feels "sweeter," whatever that means.

The reason why I've been blogging lightly these past few days is because, as a favor, I'm covering the practice for some colleagues who I'm (very) loosely affiliated with. The time demands have been great.

Nonetheless, it is a good reminder to me just how far wrong conventional cardiology remains. Judging by what I see around me, there is a startling lack of restraint in proceeding to the catheterization laboratory. Curiously, the internists and family practitioners have been brainwashed into accepting this path. I suppose that all it takes is an occasional real "save" for these physicians to develop a fear of ever missing real disease.

What I'm seeing is just how many people presenting with chest pain or similar symptoms end up going to the cath lab. I would crudely estimate 80%. That is, once you make it past the emergency room, there's a four out of five chance that you'll end up with a heart catheterization to "be sure your heart is okay", "make certain you're not going to die of heart disease", "see if there's a ticking time bomb in your chest". You've heard all the clever, scary phrases that get tossed around to scare the pants off you and justify putting catheters in your groin.

Despite the fact that tools for heart disease prevention have improved dramatically, the volume of heart catheterizations continues to grow nationwide.

I find it shocking and unacceptable. We're currently working behind the scenes to help change this situation through education of the public. Persuade a $1 million a year cardiologist that he is overdoing procedures? Unlikely in my experience. Educate the public about the shocking over-reliance on high-revenue procedures? Perhaps more practical.

Garlic May Not Lower Cholesterol
Study Shows No Improvement in Cholesterol Levels From Raw Garlic or Garlic Supplements

Lots of reports continue to hit the press about a small study that hoped to determine whether garlic as whole cloves (4 to 6), an aqueous extract of garlic called Kyolic, or an oil extract called Garlicin (high in allicin), or placebo. No differences in lipid numbers including LDL cholesterol were observed.

(Full text at WebMD at http://www.webmd.com/cholesterol-management/news/20070226/garlic-may-not-lower-cholesterol?ecd=wnl_chl_030507. You may be required to log in or register.)

I believe that the researchers were sincere in their effort to follow an honest, scientfically sound clinical trial design. I'm personally not that surprised. The effect in prior studies has been modest, sometimes none. Does that mean that we should ignore the other studies that suggest there may be modest blood-thinning, anti-inflammatory, blood pressure-reducing, and cancer-preventing properties? No, it does not. Dr. Matt Budoff at UCLA even published a very small study in about 20 people that suggested a slowing of plaque growth by using Kyolic in persons tracked by CT heart scans.

Nonetheless, garlic is, at best, probably no more than a source of small benefits. The biggest fallout from this kind of report, however, is not the neutral results from garlic, but from the open door the drug companies sense when this happens.

If you read the WebMD report, you'll notice all sorts of advertisements from drug companies for statin cholesterol drugs ("Cholesterol health center"; "Understanding Cholesterol Numbers"; "There are two sources of cholesterol: food and family"), Niaspan (which I used to support but have been discouraged by the Kos companies excessively profiteering methods and recent big Wall Street sellout).

It doesn't follow. The failure of one nutritional strategy to reduce LDL does nothave to trigger a run to the drugs. Don't fall for it. Drugs have their place. So do supplements and food choices, which can be very powerful. Drug manufacturers and their marketing people salivate when something like this comes along, an open invitation to say, "If garlic doesn't work, _____ sure does."

Jason came to the office because of chest pain. At 34 years old, he works as manager of a (non-fast food) restaurant, but indulges in lots of the odds and ends. Among his indulgences: Diet Coke.

Every time he'd have a diet Coke, he'd have chest pain. Not drinking diet Coke--no chest pain. If Jason drank coffee, no chest pain. Other foods, no chest pain. Anyway, just eliminating the diet Coke seemed to do the trick. (Aspartame?)

Anyway, that's not why I tell you Jason's story. In the midst of his evaluation, an echocardiogram showed a mildly enlarged aorta, measuring 4.0 cm in diameter. So we obtained lipoproteins. Jason showed lipoprotein(a) and small LDL particles, the dreaded duo. We talked about how to correct this pattern. Among the strategies we discussed was niacin.

But what bothered me was that neither of Jason's parents had a diagnosis of heart disease. Jason had to have gotten Lp(a) from either his mother or father, since you obtain the gene from one or the other parent. You cannot acquire Lp(a). So one of Jason's parents was sitting on a genetic time bomb of unrecognized Lp(a) and hidden heart disease.

Because Jason's paternal grandfather had a heart attack at age 62, only Jason's Dad had the heart scan (though I urged both to get one). Score: 1483. Recall that heart scan scores >1000 carry a risk of death or heart attack of 25% per year if no preventive action is taken. Now, of course, we have to persuade Jason's Dad that a program of prevention--intensive prevention is in order, including a measure of Lp(a).

So that's the curious story of how Diet Coke probably saved Jason's Dad's life. The lesson is that if you or someone you know has Lp(a), think about their children as well as their parents, each of whom carry a 50% chance of having the pattern.
