Are Your Cosmetics Safe?

11. junio 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. junio 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. junio 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. junio 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. mayo 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. mayo 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. mayo 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 som enzyme, lipoprotein lipase, to form highly atherogenic, or plaque-causing, chylomicron remnants.)

While not examined in this study, my bet is that "grazing," i.e., eating small meals or snacks frequently, is an extreme instance of triglyceride, chylomicron, and chylomicron remnant stacking. That can only lead to one thing: accelerated heart and vascular plaque.

What is a healthy vitamin D blood level?

9. November 2009 William Davis (32)

When measuring blood levels of vitamin D (as 25-hydroxy vitamin D), what constitutes a desirable level?

There's no study that directly examines this question, no study that enrolled thousands of people and assigned a placebo group and groups receiving escalating doses of vitamin D and/or achieved higher levels of vitamin D, then observed for development of cancer, diabetes, depression, heart disease, multiple sclerosis, osteoporosis, osteoarthritis, etc. Such a study would requires many thousands of participants (particularly to observe cancer and multiple sclerosis incidence), many years of observation, and many tens of millions of dollars. Nope, only a drug company could afford such costs.

So we have to piece together various observations and extrapolate what we believe to be the ideal level of vitamin D. Epidemiologic observations in several cancers (breast, colon, prostate, and bladder) suggest that a 25-hydroxy vitamin D level of 30 ng/ml or higher is desirable (with less cancer incidence above this level). Other data suggest a level of 52 ng/ml or greater is desirable. Unfortunately, much cancer research looked at intake of vitamin D from food and supplement sources, rather than actual blood levels. We also have to factor in the great individual variation in vitamin D metabolism, with a single dose yielding variable blood levels (as much as a 10-fold difference). There's also the variation introduced by vitamin D-receptor variation (genetic polymorphisms).

A new study using vitamin D administration helps chart the desirable levels of vitamin D.

Vitamin D supplementation reduces insulin resistance in South Asian women living in New Zealand who are insulin resistant and vitamin D deficient - a randomised, placebo-controlled trial.

In this New Zealand study, 42 women (23 to 68 years old) were given 4000 units vitamin D, 39 women given placebo. Median 25-hydroxy vitamin D levels increased from 21 nmol/L (8.4 ng/ml) to 75 nmol/L (30 ng/ml). Both HOMA (a measure of insulin sensitivity) and fasting insulin levels improved, with greatest improvement seen at 25-hydroxy vitamin D levels of 80-119 nmol/L (32-47.6 ng/ml) or greater.

We also know that a vacation on a Caribbean beach in a bathing suit will increase vitamin D blood levels to the 80-110 ng/ml range without ill-effect (at least in young people who maintain the capacity to activate vitamin D in the skin, a phenomenon that declines as we age).

So do we really know the truly ideal level of vitamin D to achieve? I believe that, given the above observations, it is reasonable to extrapolate that the ideal vitamin D blood level likely lies somewhere above 50 ng/ml. We also know that vitamin D toxicity (i.e., hypercalcemia) is virtually unheard of until vitamin D blood levels approach 150 ng/ml, and even then is inconsistent. The health benefits of vitamin D supplementation are so tremendous, that I am not willing to wait for the prospective data to explore this question fully. For now, I aim for a blood level of vitamin D of 60-70 ng/ml (150-175 nmol/L).

Grazing is for cattle

5. November 2009 William Davis (17)

Many dietitians and nutritionists advise many people today to "graze," i.e., to eat small snacks every couple of hours. They argue that it blocks the drop in insulin and blood sugar that can trigger greater appetite and claim it can facilitate weight loss.

This is an absurd notion. Humans are not meant to graze. Humans are meant to find a wild boar or other animal, kill it, gorge on the meat, organs, and fat, then revert to berries, roots, leaves, and other foraged foods until the next kill. A human living in the wild does not have a cupboard or refrigerator full of ready-to-eat snacks to graze on.

The several hours after a meal is the most dangerous for creating coronary atherosclerotic plaque, i.e., the post-prandial period. In other words, eat dinner and, for the next 6-12 hours, your intestinal tract degrades the food; food byproducts are absorbed into the blood or lymph system. The blood is literally flooded with the byproducts of your meal.

Postprandial abnormalities are emerging to be a potent, and much underappreciated, means of causing heart disease and atherosclerosis in other vascular territories (especially carotid arteries and thoracic aorta).

Not eating--i.e., the fasting state--for extended periods is good for you. Encouraging people to graze amplifies atherosclerotic risk, since it creates an abnormal prolonged postprandial state.

The disastrous results of a low-fat diet

4. November 2009 William Davis (16)

Rob was never that committed to following the program in the first place.

I met Rob because of a modest heart scan score and consultation for a cholesterol abnormality. Rob had been cycled through all the statin agents by his primary care physician, all of which resulted in terrible muscle aches that he found intolerable.

I started out, as usual, characterizing his cholesterol abnormality with lipoprotein testing (NMR):

LDL particle number 1489 nmol/L
LDL cholesterol (Friedewald calculation) 143 mg/dl
Small LDL 52% of total LDL
HDL 50 mg/dl
Triglycerides 82 mg/dl

(LDL particle number is the emerging gold standard for LDL quantification, superior to calculated or Friedewald LDL cholesterol for prediction of cardiovascular events.)

Rob is a busy guy. After only a couple of brief visits, life and work got in the way and Rob let his attentions drift away from heart health. Since the information I provided made little impact on his thinking, he reverted to the low-fat diet his primary care doctor had originally prescribed and that he read about in magazines and food packages. He also ran out of the basic supplements I had advised, including fish oil and vitamin D, and just never restarted them.

A couple of years passed and Rob decided that just poking around on his own might not cut it. So he came back to the office. We repeated his NMR lipoprotein analysis:

LDL particle number 2699 nmol/L
LDL cholesterol (Friedewald calculation) 229 mg/dl
Small LDL 81% of total LDL
HDL 53 mg/dl
Triglycerides 78 mg/dl

Two years of a low-fat diet had caused Rob's LDL particle number to skyrocket by 81%, nearly all due to an explosion of small LDL. Recall that small LDL is more susceptible to oxidation, more inflammation-provoking, more adhesive--the form of LDL particles most likely to cause heart disease.

Also, note that, despite the enormous increase in small LDL, HDL and triglycerides remained favorable. This counters the popular rule-of-thumb offered by some that small LDL is not present when HDL is "normal."

Low-fat diets as commonly practiced are enormously destructive. In Rob's case, a low-fat diet caused both calculated Friedewald LDL as well as LDL particle number to increase dramatically. In many other people, low-fat diets increase calculated Friedewald LDL modestly or not at all, but cause the more accurate LDL particle number to increase significantly, all due to small LDL.

I'm happy to say that, once Rob witnessed how far wrong he could go on the wrong program, he's back on Track. (Sorry, pun intended.) He has resumed his supplements and eliminated the food triggers of small LDL--wheat, cornstarch, and sugars.

Dr. David Grimes reminds us of vitamin D

3. November 2009 William Davis (13)

In response to the Heart Scan Blog post, Fish oil makes you happy: Psychological distress and omega-3 index, Dr. David Grimes offered the following argument.

Dr. Grimes is a physician in northwest England at the Blackburn Royal Infirmary, Lancashire. He is author of the wonderfully cheeky 2006 Lancet editorial, Are statins analogues of vitamin D?, questioning whether the benefits of statin drugs simply work by way of increased vitamin D blood levels.

There is a fashionable interest in Omega-3 fatty acids, and these become equated with fish oil.

But fish oil is much more. Plankton synthesise the related squalene (shark oil) which, in turn, is converted into 7-dehydrocholesterol (7-DHC). The sun now comes into play and it converts 7-DHC into vitamin D (a physico-chemical process).

Small fish eat plankton, large fish eat small fish, and we eat large fish. So vitamin D passes through the food chain.

This has been a vital source of vitamin D for the the Inuits and also for the Scots and other dwellers of northwest Europe. (Edinburgh is on the same latitude as Hudson Bay and Alaska, further north than anywhere in China). In these locations there is not adequate sunlight energy to guarantee synthesis of adequate amounts of vitamin D, again by the action of sunlight on 7-DHC in the skin.

When the Scots moved from coastal fishing villages to industrial cities such as Glasgow, they became seriously deficient in vitamin D, and so the emergence of rickets. This was followed by a variety of other diseases resulting from vitamin D deficiency: tuberculosis, dental decay, coronary heart disease, and even multiple sclerosis and depression (the Glasgow syndrome).

And so it was with the Inuits. When their diet changed from fish for breakfast, fish for lunch, fish for dinner, they became deficient of vitamin D and they developed diseases characteristic of industrial cities, where there is indoor work for long hours, indoor activities, and atmospheric pollution.

It is the vitamin D component of fish and fish oils that is important.

I recently saw an elderly lady from Bangladesh living in northwest England. I would have expected her to have a very low blood level of vitamin D, as her exposure to the sun was minimal. However the blood level was 47ng/ml, not 4 as expected. She eats oily fish from Bangladesh every day, showing its value as a source of vitamin D with subsequent good health. I expect her blood levels of omega-3 fatty acids would also be high.

But it is unfashionable vitamin D that is important, not fashionable omega-3.

David Grimes
www.vitamindandcholesterol.com

Excellent point. The health effects of omega-3 and vitamin D are intimately intertwined when examining populations that consume fish.

In this study of Inuits, it is indeed impossible to dissect out how much psychological distress was due to reduced vitamin D, how much due to reduced omega-3s. My bet is that it's both. Thankfully, we also have data examining the use of pure omega-3 fatty acids in capsule (not intact fish) form, including studies like GISSI Prevenzione.

Nonetheless, Dr. Grimes reminds us that both vitamin D and omega-3 fatty acids from fish oil play crucial roles in mental health and other aspects of health, and that it's the combination that may account for the extravagant health effects previously ascribed only to omega-3s.

Why does fish oil reduce triglycerides?

2. November 2009 William Davis (9)

Beyond its ability to slash risk for cardiovascular events, omega-3 fatty acids from fish oil also reduce triglycerides.

There's no remaining question that omega-3s do this quite effectively. After all, the FDA approved prescription fish oil, Lovaza, to treat a condition called familial hypertriglyceridemia, an inherited condition in which very high triglycerides in the 100s or 1000s of milligrams typically develop.

The omega-3 fraction of fatty acids are unique for their triglyceride-reducing property. No other fraction of fatty acids, such as omega-6 or saturated, can match the triglyceride-reducing effect of omega-3s.

But why does fish oil reduce triglycerides?

First of all, what are triglycerides? As their name suggests, triglycerides consist of three ("tri-") fatty acids lined up along a glycerol (sugar) "backbone." Triglycerides are the form in which most fatty acids occur in the bloodstream, liver, and other organs. (Fatty acids, like omega-3, omega-6, mono- or polyunsaturated, or saturated, rarely occur as free fatty acids unbound to glycerol.) In various lipoproteins in the blood, like LDL, VLDL, and HDL, fatty acids occur as triglycerides.

Of all lipoproteins, chylomicrons (the large particle formed through intestinal absorption of fatty acids and transported to the liver via the lymph system) and VLDL (very low-density lipoprotein, very low-density because they are mostly fat and little protein) particles are richest in triglycerides. Thus, we would expect that omega-3s exert their triglyceride-reducing effect via reductions in either chylomicrons or VLDL.

Indeed, that seems to be the case. The emerging evidence suggests that omega-3 fatty acids from fish oil reduce triglycerides through:

--Reduced VLDL production by the liver (Harris 1989)
--Accelerating chylomicron and VLDL elimination from the blood
--Activation of peroxisome proliferator-activated receptor gamma (PPAR-gamma)--Omega-3s ramp up the cellular equipment used to convert fatty acids to energy (oxidation) (Gani 2008)

Combine omega-3 fatty acids from fish oil with wheat elimination and you have an extremely potent means of reducing triglycerides. Read a previous Heart Scan Blog post here to read how a patient reduced triglycerides 93.5% from 3100 mg/dl to 210 mg/dl in just a few weeks using fish oil and wheat elimination.

Fish oil makes you happy: Psychological distress and omega-3 index

30. October 2009 William Davis (24)

For another perspective on omega-3 blood levels, here's an interesting study in northern Quebec Inuits.

Traditionally, Inuits consumed large quantities of omega-3-rich seal, fish, caribou, and whale, even eating the fat. However, like the rest of the world, modern Inuits have increased consumption of store-bought foods, largely processed carbohydrates. Along with this trend has emerged more heart disease, diabetes, and depression.

A group from Laval University and University of Guelph, both in Canada, examined the relationship of plasma EPA + DHA levels and measures of psychological distress. This group had previously shown that Inuits older than 50 years had twice the plasma omega-3 levels (11.5%) compared to those younger than 50 years (6.5%), reflecting the shift away from the traditional diet.

Psychological distress was measured with The Psychological Distress Index Santé-Québec Survey (PDISQS-14): the higher the score, the greater the psychological distress. (In the graphs, tertile 1 is least distressed; tertile 5 is most distressed. Sorry about the small chart graphic--click on the graphic to make it bigger.)

From Lucas M et al 2009 (http://www.nutrasource.ca/NDI/Assets/Articles/Plasma%20omega-3%20and%20psychological%20distress%20among%20Nunavik%20Inuit.pdf)

"Our main finding was that women in the second and third tertiles of EPA+DHA concentrations in plasma PLs [phospholipids] had a 3 times lower risk of having a high-level PD [psychological distress] score than women in the lowest tertile."

While the relationship is stronger for women, you can see that, the higher the EPA + DHA plasma level, the lower the likelihood of psychological distress. Interestingly, the tertile with the greatest distress and lowest EPA + DHA levels had a plasma level of 7.0-7.5%--far higher than average Americans.

(Plasma levels of EPA + DHA were used in this study, which tend to reflect more recent omega-3 intake than the more stable and slower-to-change RBC Omega-3 Index that we use. Plasma levels also tend to run about 10-20% lower than RBC levels.)

Of course, there's more to psychological distress than omega-3 blood levels. After all, eating fish or taking fish oil capsules won't make money worries go away or heal an unhappy marriage. But it is one variable that can be easily and safely remedied.

Hospitals are a hell of a place to get sick

29. October 2009 William Davis (19)

I answered a page from a hospital nurse recently one evening while having dinner with the family.

RN: "This is Lonnie. I'm a nurse at _____ Hospital. I've got one of your patients here, Mrs. Carole Simpson. She's here for a knee replacement with Dr. Johnson. She says she's taking 12,000 units of vitamin D every day. That can't be right! So I'm calling to verify."

WD: "That's right. We gauge patients' vitamin D needs by blood levels of vitamin D. Carole has had perfect levels of vitamin D on that dose."

RN: "The pharmacist says he can replace it with a 50,000 unit tablet."

WD: "Well, go ahead while Carole's in the hospital. I'll just put her back on the real stuff when she leaves."

RN: "But the pharmacist says this is better and she won't have to take so many capsules. She takes six 2,000 unit capsules a day."

WD: "The 50,000 units you and the pharmacist are talking about is vitamin D2, or ergocalciferol, a non-human form. Carole is taking vitamin D3, or cholecalciferol, the human form. The last time I checked, Carole was human."

RN: (Long pause.) Can we just give her the 50,000 unit tablet?

WD: "Yes, you can. But you actually don't need to. In fact, it probably won't hurt anything to just hold the vitamin D altogether for the 3 days she's in the hospital, since the half-life of vitamin D is about 8 weeks. Her blood level will barely change by just holding it for 3 days, then resuming when she's discharged."

RN: (Another long pause.) Uh, okay. Can we just give her the 50,000 units?"

WD: "Yes, you can. No harm will be done. It's simply a less effective form. To be honest, once Carole leaves the hospital, I will just put her back on the vitamin D that she was taking."

RN: "Dr. Johnson was worried that it might make her bleed during surgery. Shouldn't we just stop it?"

WD: "No. Vitamin D has no effect on blood coagulation. So there's no concern about perioperative bleeding."

RN: "The pharmacist said the 50,000 unit tablet was better, also, because it's the prescription form, not an over-the-counter form."

WD: "I can only tell you that Carole has had perfect blood levels on the over-the-counter preparation she was taking. It works just fine."

RN: "Okay. I guess we''ll just give her the 50,000 unit tablet."

From the alarm it raises trying to administer nutritional supplements in a hospital, you'd think that Osama Bin Laden had been spotted on the premises.

I laugh about this every time it happens: A patient gets hospitalized for whatever reason and the hospital staff see the supplement list with vitamin D, fish oil at high doses, iodine, etc. and they panic. They tell the patient about bleeding, cancer, and death, issue stern warnings about how unreliable and dangerous nutritional supplements can be.

My view is the exact opposite: Nutritional supplements are a wonderful, incredibly varied, and effective array of substances that, when used properly, can provide all manner of benefits. While there are selected instances in which nutritional supplements do, indeed, have interactions with treatments provided in hospitals (e.g., Valerian root and general anesthesia), the vast majority of supplements have none.

Does fish oil cause blood thinning?

27. October 2009 William Davis (20)

Omega-3 fatty acids from fish oil have the capacity to "thin the blood." In reality, omega-3s exert a mild platelet-blocking effect (platelet activation and "clumping" are part of clot formation), while also inhibiting arachidonic acid formation and thromboxane.

But can fish oil cause excessive bleeding?

This question comes up frequently in the office, particularly when my colleagues see the doses of fish oil we use for cardiovascular protection. "Why so much fish oil? That's too much blood thinning!"

The most recent addition to the conversation comes from a Philadelphia experience reported in the American Journal of Cardiology:

Comparison of bleeding complications with omega-3 fatty acids + aspirin + clopidogrel--versus--aspirin + clopidogrel in patients with cardiovascular disease.(Watson et al; Am J Cardiol 2009 Oct 15;104(8):1052-4).

All 364 subjects in the study took aspirin and Plavix (a platelet-inhibiting drug), mostly for coronary disease. Mean dose aspirin = 161 mg/day; mean dose Plavix = 75 mg/day. 182 of the subjects were also taking fish oil, mean dose 3000 mg with unspecified omega-3 content.

During nearly 3 years of observation, there was no excess of bleeding events in the group taking fish oil. (In fact, the group not taking fish oil had more bleeding events, though the difference fell short of achieving statistical significance.) Thus, 3000 mg per day of fish oil appeared to exert no observable increase in risk for bleeding. This is consistent with several other studies, including that including Coumadin (warfarin), with no increased bleeding risk when fish oil is added.

Rather than causing blood thinning, I prefer to think that omega-3 fatty acids from fish oil restore protection from abnormal clotting. Taking omega-3 fatty acids from fish oil simply restores a normal level of omega-3 fatty acids in the blood sufficient to strike a healthy balance between blood "thinning" and healthy blood clotting.

Heart Scan Blog readers take impressive doses of omega-3s

24. October 2009 William Davis (28)

Here are the results from the latest Heart Scan Blog poll:

What is your dose of omega-3 fatty acids, EPA + DHA, from fish oil? (Add up the total content of EPA + DHA per capsules; multiply times number of capsules.)

The 479 respondents answered:

Less than 1000 mg per day
65 (13%)

1000-1999 mg per day
145 (30%)

2000-2999 mg per day
98 (20%)

3000-3999 mg per day
79 (16%)

4000-4999 mg per day
33 (6%)

5000-5999 mg per day
14 (2%)

6000 mg per day or more
45 (9%)

The poll did not discriminate between who has heart disease, who does not; who is taking omega-3 fatty acids for high triglycerides or for reduction of lipoprotein(a) (which requires high doses), or other indications. So variation is to be expected.

We can say that nearly all respondents are likely receiving sufficient omega-3s to impact cardiovascular risk, since the benefits begin just by consuming fish twice per month. I am especially impressed at the proportion of respondents (53%) who take at least 2000 mg per day of EPA + DHA. It's clear that people are really embracing the notion that omega-3 fatty acids pack a real wallop of health benefits.

Because different people in different situations and lipid/lipoprotein patterns have different omega-3 needs, there is really no "right" or "wrong" dose of omega-3 fatty acids.

However, there are several factors that enter into knowing your ideal omega-3 intake:

--Higher triglycerides require higher doses
--Lipoprotein(a) can respond to higher doses
--Having coronary or carotid plaque means you desire a "therapeutic" dose of omega-3s, not just a "preventive" dose

Time is a factor, also: The longer you take omega-3s, the higher your blood levels go. You can accelerate the replacement of non-omega-3s with higher doses of omega-3s.

But too much is not good either. Some participants in Track Your Plaque, for instance, have experimented with very high doses of EPA + DHA in the 9000-10,000 per day range and witnessed dramatic increases in LDL.

Much of the uncertainty about dosing will also be cleared up as we get more experience with the Omega-3 RBC Index, i.e, the proportion of fatty acids in red blood cells that are omega-3s. We are currently aiming for an Omega-3 Index of 10%, given the heart attack reductions observed at this level.
