Are Your Cosmetics Safe?

11. June 2014 Dawn D (0)

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.

Keeping Up with the Kids

5. June 2014 Amber B (0)

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!

4 Tips to Boost Kids Veggie Intake

3. June 2014 Lisa G (0)

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.

When is the Best Time of Day to Workout?

2. June 2014 Amber B (0)

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.

What is Cureality all about?

27. May 2014 William Davis (1)

“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.

How Can I Lose Weight Eating Fat?

26. May 2014 Lisa G Carbohydrates, Lipids, Nutrition (0)

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.

Drowning in a Sea of "Endocrine Disrupter Toxins"

20. May 2014 Chris K Drug advertising (1)

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.

Italian Food the Cureality Way

19. May 2014 Lisa G (0)

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?

Traveling, while being wheat-free and dairy-free. Can it be done?

16. May 2014 Dawn D Dairy products, Wheat-free (0)

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~

Kitchen sink approach for Lp(a)

29. August 2008 William Davis (12)

Lipoprotein(a), Lp(a), can be a tough nut to crack.

Having struggled and wrestled with this genetic pattern for the last 12 years or so in hundreds of patients, I have gained great respect for this difficult to control pattern.

I regard lipoprotein(a) as the number one most aggressive cause for heart disease and coronary plaque known. It can account for heart attacks in men in their 40s, women in their 50s. It can cause heart disease and heart attacks in even the ultra-fit like marathon runners. It accounts for both excessive coronary risk and misleading cholesterol values in slender, healthy-appearing people.

Niacin is the number one treatment choice for Lp(a), followed by testosterone for men, estrogens (preferably human, not horse or other non-human mammal) for women. I then often resort to DHEA, along with adjunctive nutritional agents like raw almonds, ground flaxseed, and others.

Our most recent addition to the Lp(a) treatment list is high-dose fish oil, which appears to exert a significant effect in about 40% of people with Lp(a).

Even with this multi-agent approach, not everybody gains control over Lp(a).

That makes me wonder if someone has Lp(a) at a substantial level of, say, 200 nmol/L or 70 mg/dl (values can differ tremendously, depending on the method of measurement), should we throw everything but the kitchen sink at Lp(a) from the start? Right now, by adding an agent one at a time, it often takes two years to gain control over Lp(a) (if we are going to get it at all).

While many people might find this unpalatable and overwhelming from the starting gate of their program, I do believe it may be a strategy we should consider adopting for full and more immediate plaque control in the Track Your Plaque program. Something to chew on.

Clearly, we need better answers for Lp(a). A "kitchen sink," full-frontal assault might be a way to gain faster control, though not necessarily a superior approach with regards to efficacy and potency.

There are a number of unique, potentially effective therapies for Lp(a) that are worth examining. Given the difficulty of performing clinical trials with non-drug agents (largely a lack of financial support, since nobody gets a financial return with non-patent-protectable agents), I am anxious to put these potential treatments to a test in the Track Your Plaque program Virtual Clinical Trail (VCT). The VCT gives us a quick and relatively easy method to test various potential treatments, with feedback generated in months, rather than years.

Any suggestions on promising agents to test? Of course, they must be widely available nutritional agents, not drugs.

Making Dr. Friedewald an honest man

28. August 2008 William Davis (3)

Colleen started with the usual discrepancy between conventional calculated LDL cholesterol of 121 mg/dl and the far more accurate LDL particle number (NMR) of 1927 nmol/L.

Those of you following this conversation or our many conversations on the Track Your Plaque Forum know that a useful and highly reliable rule-of-thumb for converting NMR LDL particle number to LDL is to drop the last digit: 1927 nmol/L becomes 192 mg/dl. (This is, admitttedly, arrived at empirically, not by design. However, it has held up through thousands of NMR analyses and plays out reasonably when you compare distributions of Friedewald LDL and LDL particle number on a population basis.)

In other words, by this simple manipulation, Colleen's Friedewald calculated LDL is off by 58%. This is very common, a phenomenon I witness several times every day.

By LDL particle size, 75% of all Colleen's LDL particle were abnormally small (small LDL particle number 1440 nmol/L). This is a moderately severe small LDL tendency.

So we took all the steps for reduction of small LDL/LDL, including elimination of wheat and cornstarch, exercise, weight loss (which happens inevitably when wheat and cornstarch are eliminated), fish oil, vitamin D, etc.

Another NMR lipoprotein panel showed an LDL particle number of 882 nmol/L and a Friedewald calculated LDL of 87 mg/dl. Using our rule-of-thumb, LDL by particle number is virtually the same as the calculated LDL. This time, small LDL numbered only 237 nmol/L, or 26.8% of the total, a marked reduction.

Isn't that interesting? As small LDL is corrected, the crude Friedwald calculated LDL approximates the more accurate LDL particle number.

It assumes that accuracy of the Friedewald calculation may be more likely to occur as LDL size approaches normal. However, when LDL size is abnormally small--a condition shared by at least 70% of people with coronary heart disease--then the Friedewald LDL becomes increasingly inaccurate.

The opposite can also happen: When all or nearly all LDL particles are large, Friedewald calculated LDL can markedly overestimate LDL particle number. Yesterday, for instance, a patient had a Friedewald calculated LDL of 183 mg/dl, but an NMR particle number of 1110 nmol/L--drop the zero . . . LDL 110 mg/dl. This woman was advised to take a statin drug by her primary care physician, based on the Friedewald LDL. Instead, she proved to have a far lower LDL. She would not have benefitted from taking a statin drug.

As I've warned many times before: Beware the Friedewald calculated LDL.

Some basic vitamin D issues

24. August 2008 William Davis (7)

The last post on vitamin D raised a number of basic questions among readers. So let me discuss some of these questions one by one. All of them raise important issues surrounding the practical aspects of managing vitamin D in your health.

Anne said:

I think it is important to stress that vitamin D supplementation needs to be continued long term.

I have met too many people who have been prescribed 50,000 IU of D2 for 8-12 weeks and then told to stop because their 23(OH)D went over 30ng/ml. I know one person who's doctor stopped and started the D2 3 times.

Thanks for pointing that out, Anne. Excellent point. I also see doctors do this with statin drugs: start it, check a LDL level which is lower, then think that you're done and stop the drug. What the heck are they thinking?

If vitamin D is not being produced by sun exposure and not obtainable through diet, continued supplementation is necessary, essentially for life.

Twinb asked:

How often you think Vit. D levels should be tested after the initial test is done, especially if the levels are drastically low?

We have used every 6 months in the office. Ideally, levels are in mid-summer and mid- to-late winter in order to gauge the extremes of your seasonal fluctuations. While most adults over 40 fail to fluctuate more than 10 ng/ml in the Wisconsin climate (and this summer, after an initial rainy season early, has been flawlessly bright and sunny, in the high-70s and 80s every single day for months), an occasional person fluctuates more widely. The only way to judge is to check a blood level.

Rich said:

Vitamin D dosage effects appear to be quite idiosyncratic.

Yes, indeed it is. Despite using crude rules-of-thumb, like taking 1000 units of vitamin D per 10 ng/ml desired (a rule I learned from Dr. John Cannell, which he offered fully aware of its inaccuracy), many people will surprise you and have levels that make no sense. Testing is crucial to know your vitamin D level.

Richard asked: Where do we get enough vitamin D wihout worring about laboratory tests?

Well, the entire point of the post was that you absolutely, positively cannot just take vitamin D blindly at any dose and hope that your level is ideal, no more than you can blindly take a dose of thyroid and know you have achieved normal thyroid levels. In my view, vitamin D blood levels are an absolute.

Another simple issue: Don't be afraid of vitamin D. It is, in all practicality, no more dangerous than getting a dark tan. (But, as many of you realize, getting a tan is no assurance of raising vitamin D if you are over 40 years old.)

Wouldn't it be great if someone developed a do-it-yourself-at-home skin test for vitamin D? I know of no effort to develop this, but it would be a huge advantage for all of us.

“How much vitamin D should I take?”

22. August 2008 William Davis (17)

It’s probably the number one most common question I get today:

“How much vitamin D should I take?”

Like asking for investing advice, there are no shortage of people willing to provide answers, most of them plain wrong.

The media are quick to offer advice like “Take the recommended daily allowance of 400 units per day,” or “Some experts say that intake of vitamin D should be higher, as high as 2000 units per day.” Or “Be sure to get your 15 minutes of midday sun.”

Utter nonsense.

The Food and Nutrition Board of the Institute of Medicine has been struggling with this question, also. They have an impossible job: Draft broad pronouncements on requirements for various nutrients by recommending Recommended Daily Allowances (RDA) for all Americans. The Food and Nutrition Board has tried to factor in individual variation by breaking vitamin D requirements down by age and sex, but what amounts to a one-size-fits-nearly-all approach.

Much of the uncertainty over dosing stems from the fact that vitamin D should not be called a “vitamin.” Vitamins are nutrients obtained from foods. But, outside of oily fish, you'll find very little naturally-occurring vitamin D in food. (Even in fish, there is generally no more than 400 units per 4 oz. serving.) Sure, there’s 20 units in an egg yolk and you can activate the vitamin D in a shiitake mushroom by exposing it to ultraviolet radiation. Dairy products like milk (usually) contain vitamin D because the USDA mandates it. But food sources hardly help at all unless you’re an infant or small child.

It all makes sense when vitamin D is viewed as a hormone, a steroid hormone, not a vitamin. Vitamin-no, steroid hormone-D exerts potent effects in tiny quantities with hormone-like action in cells, including activation of nuclear receptors.

It is the only hormone that is meant to be activated by sun exposure of the skin, not obtained through diet. But the ability to activate D is lost by the majority of us by age 40 and even a dark tan is no assurance that sufficient skin prohormone D activation has taken place.

As with any other hormone, such as thyroid, parathyroid, or growth hormones, dose needs to be individualized.

Imagine you developed a severely low thyroid condition that resulted in 30 lbs of weight gain, lose your hair, legs swell, and heart disease explodes. Would you accept that you should take the same dose of thyroid hormone as every other man or woman your age, regardless of your body size, proportion of body fat, metabolism, genetics, race, dietary habits, and other factors that influence thyroid hormone levels? Of course you wouldn’t.

Then why would anyone insist that vitamin D be applied in a one-size-fits-all fashion? (There’s another world in which a one-size-fits-all approach to hormone replacement has been widely applied, that of female estrogen replacement. In conventional practice, there’s no effort to identify need, estrogen-progesterone interactions, nor assess the adequacy of dose, not to mention the perverse non-human preparation used.)

With thyroid hormone, ideal replacement dose of hormone ranges widely from one person to another. Some people require 25 mcg per day of T4; others require 800% greater doses. Many require T3, but not everybody.

Likewise, vitamin D requirements can range widely. I have used anywhere from 1000 units per day, all the way up to 16,000 units per day before desirable blood levels were achieved.

Vitamin D dose needs to be individualized. Factors that influence vitamin D need include body size and percent body fat (both of which increase need substantially); sex (males require, on average, 1000 units per day more than females); age (older need more); skin color (darker-skinned races require more, fairer-skinned races less); and other factors that remain ill-defined.

But these are “rules” often broken. My office experience with vitamin D now numbers nearly 1000 patients. The average female dose is 4000-5000 units per day, average male dose 6000 units per day to achieve a blood level of 60-70 ng/ml, though there are frequent exceptions. I’ve had 98 lb women who require 12,000 units, 300 lb men who require 1000 units, 21-year olds who require 10,000 units. (Of course, this is a Wisconsin experience. However, regional differences in dosing needs diminish as we age, since less and less vitamin D activation occurs.)

Let me reiterate: Steroid hormone-vitamin D dose needs to be individualized.

There’s only one way to individualize your need for vitamin D and thereby determine your dose: Measure a blood level.

Nobody can gauge your vitamin D need by looking at you, by your skin color, size, or other simple measurement like weight or body fat. A vitamin D blood level needs to be measured specifically-period.

Unfortunately, many people balk at this, claiming either that it’s too much bother or that their doctor refused to measure it.

I would rank normalizing steroid hormone-vitamin D as among the most important things you can do for your health. It should never be too much bother. And if your doctor refuses to at least discuss why he/she won’t measure it, then it’s time for a new doctor.

If you’re worried about adding to rising healthcare costs by adding yet another blood test, think of the money saved by sparing you from a future of cancer, heart disease, osteoporosis, diabetes, etc. The cost of a vitamin D blood test is relatively trivial (around $40-50, a fraction of the cost of a one month supply of a drug for diabetes.)

So how much vitamin D should you take? Enough to raise your blood level of 25-hydroxy vitamin D to normal. (We aim for a normal level of 60-70 ng/ml.)

You probably don't take enough fish oil

20. August 2008 William Davis (17)

The results of the recent Heart Scan Blog survey in response to the question: MY DAILY DOSE OF EPA + DHA FROM FISH OIL IS revealed:

Zero--I don't take any
17 (7%) of respondents

Less than 1000 mg per day
24 (10%) of respondents

1000-2000 mg per day
91 (38%) of respondents

2000-3000 mg per day
44 (18%) of respondents

3000-4000 mg per day
40 (16%) of respondents

More than 4000 mg per day
20 (8%) of respondents

Based on the above results, I would say that only a minority of respondents are taking an ideal dose of omega-3 fatty acids. Nearly all of us should consider taking more.

Benefits of omega-3 fatty acids (EPA + DHA) from fish oil begin around a dose of 840 mg per day, according to the GISSI Prevenzione Trial of 1999, an 11,000-participant trial. This dose also corresponds to a quantity of omega-3s that have been shown to raise EPA + DHA blood levels and thereby reduce the notoriously high AA:EPA ratio of Americans.

But what dose is sufficient? What dose is ideal?

Well, the answer to a great degree depends on what you are taking the fish oil for. If being taken to reduce triglycerides and triglyceride-containing lipoproteins, like VLDL and the after-eating (postprandial) IDL, then a higher dose will be necessary. (Triglyceride reduction for the genetically-determined very high triglyceride level of familial hypertriglyceridemia is the FDA-approved indication for prescription Lovaza.)

If you are taking fish oil for treatment of ADHD, depression, or bipolar illness, very high doses are often necessary.

But how about maximal reduction of cardiovascular risk and for control or reversal of atherosclerotic plaque?

This conversation is still evolving. But we can learn some important lessons from three populations of the world that are vigorous consumers of fish:

--The Inuits (aka Eskimos) of Greenland and northern Canada
--The Japanese
--The Bantus of Tanzania who live along Nyasa Lake

All three indigenous populations have several-fold greater intakes of fish and omega-3 fatty acids, have higher blood levels of omega-3 fatty acids, and have enjoyed reduced cardiovascular events, reduced atherosclerotic plaque, or improvement in various surrogates of cardiovascular risk (e.g., Lp(a)).

The most recent addition to this conversation is the ERA JUMP Study, discussed in a previous Heart Scan Blog post. In ERA JUMP, despite being heavy smokers and having other markers for greater risk for heart disease, Japanese men living in Japan had markedly less carotid and coronary plaque, as compared to Caucasian men living in PIttsburgh or Hawaiian men of Japanese descent. The difference appeared to be attributable to serum levels of omega-3 fatty acids.

I believe that the trend is here is to increase the amount of omega-3 fatty acids that most of us take. In the Track Your Plaque program, we have been advocating a rock-bottom starting dose of EPA + DHA of 1200 mg per day. However, I believe that this is due for a change.

We will be increasing the minimum dose for plaque regression and control. Please attend our Webinar this evening for a full, in-depth discussion of the rationale behind this important change.

As always, let me remind you that I am not selling, nor ever have sold, fish oil supplements. If I advocate a specific dose, a higher dose, I do so based on my interpretation of the data and experience with patients, not because I am interested in selling brand X of fish oil.

Vitamin D and HDL

19. August 2008 William Davis (23)

Despite the paucity of scientific documentation of this phenomenon, I am continuing to witness extraordinary increases in HDL cholesterol levels with vitamin D supplementation.

I've touched on the interaction of vitamin D supplementation with HDL in The Heart Scan Blog previously:

Vitamin D: Treatment for metabolic syndrome?

HDL for Dummies

At first, I thought it was attributable to other factors. In real life, most people don't modify one factor at a time. They reduce
processed carbohydrates/eliminate wheat and cornstarch, lose weight, add or increase omega-3 fatty acids from fish oil, begin niacin, increase exercise and physical activity. All these efforts also impact on HDL.

Among the many things I do, I consult on complex lipid (cholesterol) disorders (complex hyperlipidemias) in my office. A substantial number of these people carry a diagnosis of hypoalphalipoproteinemia, a mouthful that simply means these people are unable to manufacture much apoprotein A1, the principal protein of HDL cholesterol particles. As a result, people with hypoalphalipoproteinemia have HDL cholesterol levels in the neighborhood of 20-30 mg/dl--very low. They are also at high risk for heart disease and stroke.

Encourage these people to exercise, attain ideal weight, eliminate wheat and cornstarch: HDL increases 5 mg/dl or so.

Add niacin, HDL increases another 5-10 mg/dl.

Perhaps we're now sitting somewhere around an HDL of 35-40 mg/dl--better, but hardly great.

Add vitamin D to achieve our target serum level . . . HDL jumps to 50, 60, 70, even 90 mg/dl.

The first few times this occurred, I thought it was an error or fluke. But now that I've witnessed this effect many dozens of time, I am convinced that it is real. Just today, I saw a 40-year old man whose starting HDL was 25 mg/dl increase to 87 mg/dl.

Responses like this are supposed to be impossible. Before vitamin D, I had never witnessed increases of this magnitude.

Not all therapies for raising HDL raise the important large (also known as HDL2b) fraction. With lipoprotein analyses, it appears that is principally the large fraction of HDL that rises with vitamin D supplementation.

Why? How?

That I can't tell you. But for those of you struggling with low HDL cholesterols despite your best efforts, vitamin D can make a world of difference.

An interesting corollary: If super-high HDL cholesterols are associated with extreme longevity, as they are with centenarians, does raising HDL to extraordinary levels with vitamin D lead to longer, healthier life, all the way up to age 110 years?

Again, no answers, but an interesting thought. And one I'd bet on. (And I'm not selling vitamin D.)

Weight loss and blood pressure

15. August 2008 William Davis (6)

Here's another thought with regards to time issues with weight loss: reductions in blood pressure (BP).

The previous post talked about how triglycerides initially go up, sometimes way up, when weight drops, only to be followed months later by substantial drops. HDL initially drops in response to the triglyceride fluctuations, only to be followed by a rise.

Blood pressure also shows a curious pattern that is largely dependent on age.

Say someone in their 20s or 30s, for instance, loses 30 lbs (through elimination of wheat and cornstarch, say). BP usually drops within a few weeks, perhaps a month or two at most.

How about someone in their 70s? Say a substantial amount of weight is lost, say 50 lbs over 6 months. BP does indeed drop, but it may require 6 months or longer after weight plateaus for the full effects of BP-reduction to be fully expressed. But it will eventually drop.

Why the age-dependent difference?

It relates to the capacity of arteries to remain flexible and distensible. Over the years, cross-linking of collagen (a structural protein), glycation (glucose molecules attaching to proteins), loss of endothelial responsiveness to generate artery-dilating substances like nitric oxide, and arterial atherosclerotic plaque all all up to making older arteries less able to "relax" and BP to drop.

But given time and the proper effort, BP will eventually drop. Awareness of this time effect can help most people decide better when medications are necessary or if weight loss alone is sufficient to reach BP goals.

"I lost 30 lbs and my triglycerides went . . . up?"

13. August 2008 William Davis (6)

Brad needed to lose weight.

At 6 ft tall, he began the program at 291 lbs, easily 80 lbs overweight. He wore virtually all of it in his belly.

He had laboratory numbers to match: HDL 33 mg/dl, triglycerides 225 mg/dl, LDL (calculated) 144 mg/dl, blood sugar 122 mg/dl (fasting--clearly "pre-diabetic"), c-reactive protein 3.0 mg/dl. Among his lipoprotein abnormalities: small LDL representing 80% of all LDL (no surprise).

Readers of The Heart Scan Blog know that these are the patterns of the carbohydrate-indulgent. I asked Brad to eliminate all wheat flour products, all foods made with cornstarch, and follow a diet rich in healthy oils, raw nuts, vegetables, and lean meats.

Brad returned for a discussion about follow-up basic lipids (cholesterol) values four months later--31 lbs lighter, most of it clearly lost from his abdomen. He claimed he felt more energetic and clear-headed than he had in years.

His lipid panel: HDL 34 mg/dl, LDL 122 mg/dl, triglycerides 295 mg/dl. Brad's smile dissolved. "How could that happen? You said losing weight would make my HDL go up and my triglycerides go down!"

Yes, I had said that. But I was oversimplifying.

The truth is that, when there is weight loss, especially profound weight loss like Brad experienced eliminating wheat and cornstarch products, there is mobilization of fat stores. Fat is stored energy. Energy is stored as . . . triglycerides.

So when there is substantial weight loss, there is a flood of triglycerides in the blood, and triglyceride levels in the midst of weight loss can commonly jump up, not uncommonly to the 200-300+ mg/dl range. When triglycerides go up, there is also a drop in HDL (triglycerides interact with HDL particles, modify their structure and make them more readily destroyed, thereby dropping blood levels). Occasionally, substantial weight loss like Brad experienced will drop HDL really low, as low as the 20's.

Once weight stabilizes, this effect can last up to 2 months before correcting. Only then will triglycerides drop and HDL rise. The rise in HDL occurs even more slowly, requiring several more months to plateau.

In other words, weight loss like Brad's causes triglycerides to increase and HDL to decrease, to be followed later by a drop in triglycerides and a rise in HDL.

I know of no way to block this phenomenon. And perhaps we shouldn't, since this is how fat stores are mobilized and "burned off." Fish oil does blunt the triglyceride rise (perhaps through activation of lipoprotein lipase, an enzyme responsible for clearance of triglycerides), but doesn't eliminate it.

I call these changes "transitional" changes in lipids.

Patience pays. A few more months from now, Brad's numbers will be much happier, as will Brad.

Divorce court for the doctor-patient relationship?

10. August 2008 William Davis (4)

The doctor-patient relationship has gone sour.

This probably comes as no surprise to most of you, particularly if you've been following conversations here in The Heart Scan Blog:

Who is your doctor? discussing the emergence of the physician-as-hospital-employee phenomenon that causes your doctor to become the de facto portal (seller?) of hospital services to you, a model fraught with conflicts of interest.

Exploitation of trust, my observation that the enormous gap in heart disease prevention between the woefully ignorant (by necessity) level of sophistication of the primary care physician and the procedure-obsessed cardiologist leads to an exploitation of humans-for-heart-procedures because of the failure to institute genuine preventive efforts.

Bait and switch , a description of how a minor test or symptom can reap a bonanza of medical testing; a $20 "screening" test yields $10's of thousands in hospital procedures. If it were entirely due to the imprecision of medical testing and detection of disease, that might be forgivable. But it often is not: It has become utterly distorted by the profit model.

Lest you think that I am a kook ranting off in some backwoods corner (Milwaukee), here are the comments of New York Times' Health Editor Tara Parker-Pope in a series called Doctor and Patient, Now at Odds:

Lately I've been hearing a lot from patients who are frustrated, angry, and distrustful of doctors. Their feelings speak to a growing disconnect between doctors and patients and worries that drug companies, insurance rules, and hospital cost-cutting are influencing the care and advice that doctors provide.

Research shows that even among patients who like their personal physicians, there is a simmering distrust of the medical system and the doctors who work inside it.

(There's also a series of candid video interviews with people who echo these sentiments.)

There are a number of reasons for this increasing "disconnect," some of them articulated by Ms. Parker-Pope, others detailed in my blog posts.

The solutions, however, will not be found by advancing technology: the newest robotic surgery, a better defibrillator, a new statin drug, the next best chemotherapeutic agent. It will not be found by adding a new wing to the hospital. It will not be found by the reorganization of healthcare delivery achieved by converting primary care and specialty practice into an arm of hospital care. It will not be improved by employing "hospitalists." It will not emerge from legislation controlling insurance company practices. It certainly will not come from increasing marketing dollars spent by drug companies (who make $4 for every $1 spent on direct-to-consumer marketing).

The solutions will come from shifting the idea of care from a paternalistic, "I'm the doctor and I'll tell you what to do" approach, to the doctor-as-advocate-and-supporter of the patient. The physician should act as someone with a particular sort of expertise that can advise a patient.

But a caveat: The patient MUST be informed.

Proper information will not originate with the doctor. It will originate with internet-based information portals and tools that help you understand the issues, often with far greater depth than your doctor could ever provide. The physician needs to accept this role, one of advocate, adviser, but not of being in charge, not of viewing the patient as profit-center, not as an opponent in a power struggle.

Sadly, the last few years in online information portals has been dominated by the drug company-dominated websites like WebMD, nothing more than a deliverer of the conventional wisdom with nothing whatsoever aimed towards empowering patients in a self-directed healthcare model.

Some people call the emerging new empowered and information-armed patient Medicine 2.0. Unfortunately, Medicine 2.0 will first benefit the intellectual upper crust of Americans, the web-savvy and motivated to engage in health issues. But, give it 10 years, and we will witness the effects on an unprecedented broad scale. Part of the Information Age is acceleration of information dissemination. Imagine your children, facile with a computer mouse, posting comments on FaceBook, doing homework with Google and Wikipedia, now turning their attentions to health.

It will be a startling change.

In the meantime, be wary. Be empowered. Think increasingly about self-direction in your health.

In a comment to the Bait and switch post, Jennytoo offered an insightful response:

You are getting to the essence of the problem, and it's not just cardiology that is rife with what is, at bottom, malpractice.

There is little incentive for the profession as a whole to know anything about or promote prevention, and many incentives from hospitals, drug and insurance companies to stick with the status quo or to change it in their corporate favor. The formulaic, conventional statements purporting to be guidelines for prevention that are put out by various interest groups and in such publications as hospital-sponsored newsletters ("eat a 'balanced diet', avoid stress, etc.") are useless sops to the concept of prevention.

It is, and I fear is going to remain, up to motivated individuals, both physicians and patients, to reshape the system, and it's going to be a long frustrating struggle.

It's my personal conviction that if just 4 things were promoted to the public, and people actually practiced them, we could change the health profiles of the majority of people in this country for the better within two years or less. They are:

(1) education on and promotion of a true low-carbohydrate, whole foods, diet,
(2) measurement and supplementation of Vitamin D3,
(3) supplementation with DHA/EPA (found in Fish Oils), and
(4) measurement and supplementation of intracellular magnesium.

I am not a health professional, and others may want to add to this list, but I don't think any strong case can be made against any of the items. The wonderful and hopeful thing is that each of us can implement them ON OUR OWN, and thereby take charge of our own well-being. (The Life Extension Foundation is one organization which provides access to lab tests you can request on your own.)

If you have a physician who is willing and capable of being your partner, you are richly blessed, and that is the ideal we all should hope for. But in the more likely event that you do not have such a physician, and if your physician demonstrates little potential for becoming one, think about firing the one you have and finding another.

Sometimes we are forced by circumstances, particularly urgent ones, to deal with physicians who are not ideal, but the main impetus for change will come from us, the patients, and the expectations we communicate to our individual doctors. In the meantime, we can be self-reliant in our own prevention practices.

Wow. A woman after my own heart.

How much fish oil is enough?

9. August 2008 William Davis (7)

This post just furthers this line of thinking out loud: How much fish oil is "enough"?

Observations over the last 30 years followed this path: If a little bit of omega-3 fatty acids from fish are beneficial in reducing cardiovascular events, and a moderate intake is even better, is even more better? When have we reached a plateau? When do adverse effects outweigh the benefits?

Some insight can be gained through studies that examined blood levels of omega-3s. Let's take a look at some data from 2002, a comparison of men dying from heart disease vs. controls in the Physicians' Health Study, Blood Levels of Long-Chain n–3 Fatty Acids and the Risk of Sudden Death.

This is a table that shows the blood levels of various fatty acids Group with sudden death vs Control Group:

Several observations jump out:

--The total omega-3 blood content differed significantly, 4.82 vs 5.24% ("Total long-chain n-3 polyunsaturated")
--Total omega-6 content did not differ
--Arachidonic acid (AA) content did not differ
--Linolenic acid content did not differ (i.e., plant sourced omega-3)

The fact that neither omega-6 nor arachidonic acid content differed counters the argument that Simopoulos has made that the omega-6 to omega-3 ratio (intake, not blood levels) is what counts. It also argues against the EPA to AA ratio (and similar manipulations) that some have argued is important. In this study, only the omega-3 level itself made a difference; no ratio was necessary to distinguish sudden death victims vs controls.

Further, quartiles of omega-3 blood levels showed graded reductions of risk:

An omega-3 blood level of 6.87% conferred greatest risk reduction. Depending on the model of statistical analysis, risk reductions of up to 81-90% were observed. Wow.

Taken at face value, this study would argue that:

--An omega-3 fatty acid blood level of 6.87% (or greater?) is ideal
--The omega-3 fatty acid blood level stands alone as a predictor without resorting to any further manipulation of numbers, such as relating EPA and/or DHA to AA levels.

Of course, this is just one study, though an important one. It is also not a study based on any intervention, just an observational effort. But it does add to our understanding.

We will develop these issues further in our upcoming Track Your Plaque Webinar on Wednesday, August 20th, 2008.

Fat Head, Wheat belly, and the Adventures of Ancel Keys

14. March 2010 William Davis (22)

Here's another great clip from Tom Naughton's documentary, Fat Head, describing the colossal mistakes made in "official" dietary advice, starting with the blunders of Dr. Ancel Keyes :

I'd be crying if Tom Naughton didn't make me laugh so hard.

Fat Head: Tom Naughton's manifesto for low-carb eating

12. March 2010 William Davis (16)

I just got back from Jimmy Moore's low-carb cruise to the Bahamas.

Among the many interesting people I met on the cruise was the creator of the documentary film, Fat Head, Tom Naughton.

Tom brings both creative insights into low-carbohydrate eating as well as humor. Low-carb eating can be a pretty contentious issue, but Tom made it fun. He will make you laugh about many of the odd notions we have about diet.

Among the best parts of Fat Head is Tom's portrayal of the effects of carbohydrates on insulin and fat metabolism:

Fat Head joins the ranks of films like Food, Inc, that make nutrition information entertaining. For anyone interested in a unvarnished look at diet, weight loss, along with a few laughs along the way, Tom Naughton's Fat Head is worth viewing.

Oatmeal: Good or bad?

11. March 2010 William Davis (67)

You've heard it before: oatmeal reduces cholesterol. Oatmeal producers have obtained permission from the FDA to use a cholesterol-reducing claim. The American Heart Association provides a (paid) endorsement of Quaker Oats.

I've lost count of the times I've asked someone whether they ate a healthy breakfast and the answer was "Sure. I had oatmeal."

Is this true? Is oatmeal heart healthy because it reduces LDL cholesterol?

I don't think so. Try this: Have a serving of slow-cooked (e.g., steel-cut, Irish, etc.) oatmeal. Most people will consume oatmeal with skim or 1% milk and some dried or fresh fruit. Wait an hour, then check your blood sugar.

If you are not diabetic and have a fasting blood sugar in the "normal" range (<100 mg/dl), you will typically have a 1-hour blood glucose of 150-180 mg/dl--very high. If you have mildly increased fasting blood sugars between 100 and 126 mg/dl, postprandial (after-eating) blood sugars will easily exceed 180 mg/dl. If you have diabetes, hold onto your hat because, even if you take medications, blood sugar one hour after oatmeal will usually be between 200 and 300 mg/dl.

This is because oatmeal is converted rapidly to sugar, and a lot of it. Even if you were to repeat the experiment with no dried or fresh fruit, you will still witness high blood sugars in these ranges. Do like some people and pile on the raisins, dried cranberries, or brown sugar, and you will see blood sugars go even higher.

Blood sugars this high, experienced repetitively, will damage the delicate insulin-producing beta cells of your pancreas (glucose toxicity). It also glycates proteins of the eyes and vascular walls. The blood glucose effects of oatmeal really don't differ much from a large Snickers bar or bowl of jelly beans.

If you are like most people, you too will show high blood sugars after oatmeal. It's easy to find out . . . check your postprandial blood sugar.

In past, I recommended oat products, specifically oat bran, to reduce LDL, especially small LDL. I've changed my mind: I now no longer recommend any oat product due to its blood sugar-increasing effects.

Better choices: eggs, ground flaxseed as a hot cereal, cheese (the one dairy product that does not excessively trigger insulin), raw nuts, salads, leftovers from last evening's dinner.

Mustard: Super health food?

6. March 2010 William Davis (32)

Could mustard--yes, the yellow condiment you smear on hot dogs--be a super heart healthy food in disguise?

Consider that mustard contains:

Vinegar

Turmeric

No appreciable sugar

The vinegar slows gastric emptying, resulting in slower absorption of any carbohydrates and a reduced glucose area-under-the-curve. Of the little fats contained (about 3 grams per 1/4 cup), most are desirable monounsaturates. Mustards are relatively rich in selenium, with 20 mcg per 1/4 cup, helpful for protection against cancer and thyroid disease, and magnesium, 31 mg per 1/4 cup.

Turmeric is added to most mustards. One of the constituents of turmeric, curcumin, the substance that confers the bright yellow color, has been a focus of interest for its anti-inflammatory effects. Curcumin has been documented to reduce activity of the inflammatory enzymes cyclooxygenase-2 (COX-2), lipoxygenase, and reduce activity of inflammatory signal molecules, tumor necrosis factor-alpha (TNF-a), interleukin (IL)-1,2,6,8, and 12, and monocyte chemoattractant protein (MCP). Curcumin also has been shown to reduce LDL oxidation, a potentially important step in atherosclerotic plaque formation. Turmeric is used as a tea by Okinawans. (Hmmmm . . . )

Turmeric content of mustard can vary, of course. Likewise, sugar content. Look for mustards that are not sweetened, so avoid honey mustard in particular. Look for hot, brown, horseradish, Dijon, etc. If there is a downside to mustard, it's sodium content, though the 709 mg per 1/4 cup should only be a problem for those who are sodium-sensitive (African Americans, in particular).

So perhaps mustard isn't exactly a super health food. But it may have some bona fide health effects and should be used generously especially if you are concerned about blood sugar and inflammatory phenomena.

Exercise and blood sugar

5. March 2010 William Davis (30)

There is no doubt that exercise yields benefits across a spectrum of health: reduced blood pressure, reduced inflammation, reduced blood coagulation, better weight control, stronger bones, less depression, reduced risk for heart attack.

Exercise also influences blood sugar. Diabetics understand this best: Exercise reduces blood sugar 20, 30, 50 or more milligrams. A starting blood sugar, for instance, of 160 mg/dl can be reduced to 80 mg/dl by jogging or riding a bicycle. (I recently had brunch at an Indian restaurant with my family. Blood sugar one-hour postprandial: 134 mg/dl. I was sleepy and foggy. I got on my stationary bike and pedalled at a moderate clip for 60 minutes. Blood sugar: 90 mg/dl.)

Could the reduction of blood sugar with exercise be THE reason that exercise and physical activity provide such substantial benefits?

Think about it. Reduced blood sugar:

1) Reduces risk for future cardiovascular events.
2) Reduces glycation of proteins, i.e., reduced glucose binding to proteins like the ones in artery walls and the lenses of your eyes.
3) Reduces blood coagulation
4) Reduces endothelial dysfunction (abnormal artery constriction that leads to atherosclerosis)

This might explain why it doesn't require high levels of aerobic activity to derive benefit from exercise, since even modest efforts (e.g., a 15-minute walk after eating) reduce blood sugar substantially.

The incredible 33-year, 18,000-participant Whitehall study tells us that a postprandial (after-eating) blood sugar of an impossibly-difficult 83 mg/dl is required to erase the excess cardiovascular risk of blood sugar. Could this simply be telling us that physical activity or exercise is required to suppress blood sugars to these low levels?

It makes me wonder if an index of the adequacy of exercise is your post-exercise blood glucose.

The most important weight loss tool

4. March 2010 William Davis (15)

Question: What is the most effective tool available to help you lose weight?

A pedometer (walk 10,000 steps, etc.)?

A treadmill?

A bicycle?

No. None of the above.

The most important tool you can use to achieve weight loss is your glucose monitor:

Timing of blood sugars

3. March 2010 William Davis (5)

Because different foods generate different blood sugar (glucose) responses, the timing of your blood sugar is an important factor to consider.

This question has come up a number of times. Commenters have asked whether the one-hour postprandial glucose is timed with the start of the meal or the conclusion of the meal.

In my view, if we simply ignored all aspects of meal composition, then blood glucose should be obtained one hour after the conclusion of a meal. This is because most mixed meals (i.e., mixed in composition among proteins, fats, and carbohydrates) yield peak blood glucose levels at 60-90 minutes after consumption. Timing blood glucose to 60 minutes after the conclusion of a meal puts the sample right about at the peak.

But this is an oversimplification. For instance, here is the blood glucose behavior after so-called "complex" carbohydrates wheat bread, rye bread, rye made with beta glucan, and whole wheat pasta (50 grams carbohydrates each) in slender, healthy volunteers, mean age 29 years:

From Juntunen et al 2002

Note that blood glucose peaks at 35 minutes postprandial. (To convert glucose in mmol/L to mg/dl, multiple by 18. Thus, whole wheat bread increased blood glucose from 94 mg/dl to 122 mg/dl. Also note the lower peak glucose for pasta, but sustained higher glucose levels hours later.)

In another study, older (mean age 64 years), overweight (BMI 27.9) females with diabetes were given 50 grams carbohydrate, 50 grams carbohydrate with olive oil, or 50 grams carbohydrate with butter:

From Thomsen et al 2003. Control meal of soup plus 50 g carbohydrates ( {blacktriangledown}

), the control meal plus 80 g olive oil ( {circ}

), and the control meal plus 100 g butter (•).

In this experience, note that postprandial glucose peaks 60-120 minutes after the meals (consumed within 10 minutes), delayed more when either oil is included. Blood glucose started at 144 mg/dl and peaked as high as 230 mg/dl with carbohydrates only; peaks were reduced (along with AUC) when oil was included. (Note the differential effect, olive oil vs. butter.)

These two sets of observations give you a range of blood glucose behavior. One side lesson: Carbohydrates should never consumed by themselves, else you will pay with a high blood sugar (not to mention the hypoglycemic response later for many).

Psssst . . . There's sugar in there

1. March 2010 William Davis (13)

You non-diabetics who check your postprandial blood sugars already know: There are hidden sources of sugar in so many foods.

By now, everybody should know that foods like breakfast cereals, breads, bagels, pretzels, and crackers cause blood sugar to skyrocket after you eat them. But sometimes you eat something you thought was safe only to find you're showing blood sugars of 120, 130, 150+ mg/dl.

Where can you find such "stealth" sources of sugars that can screw up your postprandial blood sugars, small LDL, inflammation, blood pressure, and cause you to grow visceral fat? Here's a few:

Balsamic vinaigrette
Many commercially-prepared balsamic vinaigrettes, especially the "light" varieties, have 3 or more grams carbohydrates per tablespoon. Generous use of a sugar-added vinaigrette can therefore provide 12+ grams carbs. (Some, like Emeril's and Wish Bone, also contain high-fructose corn syrup.)

Hamburgers
I learned this lesson the hard way by taking my blood sugar after having a hamburger, turkey burger, or vegetarian burger (without bun): blood sugar would go way up. The effect is due to bread crumbs added to the meat or soy.

Tomato soup
If it were just tomatoes, it would still be somewhat high in sugars. But commercially-prepared tomato soup often contains added high-fructose corn syrup, sucrose, and wheat flour, bringing sugar totals to 12 to 20+ grams per half-cup. A typical 2-cup bowl of tomato soup can have upwards of 80 grams of sugar.

Granola
Sure, granola contains a lot of fiber. But most granolas come packed with sugars in various forms. One cup of Kellogg's Low-fat Granola with Raisins contains an incredible 72 grams (net) carbohydrates, of which 25 grams are sugar.

Given modern appetites and serving sizes, you can see that it is very easy to get carried away and, before you know it, get exposed to extraordinary amounts of sugar and carbohydrates eating foods you thought were healthy.

And don't be fooled by claims of "natural" sugar. Sugar is sugar--Just check your blood sugar and you'll see. So raw cane sugar, beet sugar, and brown sugar have the same impact as white table sugar. Honey, maple syrup, and agave? They're worse (due to fructose).

How low should blood sugar be?

What should your blood sugar (glucose) be after eating?

Take a look at the data from the Whitehall study reported in 2006. The Whitehall Study stands apart from other studies in that it was very large (over 18,000 participants) who were observed for an unusually long time (33 years). All participants were administered a 50 gram glucose "challenge" at the start with glucose levels checked after the glucose challenge.

Here's what they found:
