Triglyceride and chylomicron "stacking"

10. November 2009 William Davis (24)

Continuing the comments started in Grazing is for cattle, here's an interesting study from the Oxford Center for Diabetes, Endocrinology and Metabolism.

Volunteers were fed a test meal breakfast of Rice Krispies, a banana, and a chocolate milkshake (76.4 grams carbohydrates, 51.9 grams fat, 12.2 grams protein). Lunch was served 5 hours later and consisted of a cheese sandwich and a second chocolate milkshake 43.4 grams carbohydrates, 49.6 grams fat, 24.0 grams protein). Frequent blood samples were then assessed over the day. (Don't try this at home: These are obviously very dangerous foods!)

Here's the pattern of triglycerides that was observed (1st dotted vertical line = breakfast, 2nd dotted vertical line = lunch):

Note that triglycerides only begin to decline 3-4 hours after breakfast, only to peak higher after lunch.

Here's the pattern observed for chylomicrons, the "granddaddy" of lipoproteins that derives from intestinal absorption of fatty acids:

Both graphs from Heath RB et al Am J Phyiol Endocrinol Metab 2006.

With chylomicrons, note a similar pattern to triglycerides: Chylomicrons begin to decline at 3-4 hours, only to peak higher after lunch.

This is the first study to examine the effect of sequential meals on such postprandial (after-eating) patterns. But it makes the graphic point that, if insufficient time is permitted between meals, both triglycerides and chylomicrons will "stack" themselves higher and higher. (Chylomicrons are subjected to processing by the 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.

Is shock therapy the answer to “cure” obesity?

10. August 2014 Lisa G (0)

The next obesity “fix” may be hitting the market known as "VBLOC therapy”. This implanted device delivers intermittent electrical "blocking signals" to the intra-abdominal vagus nerve. According to the manufacturer, the device "reduces sensations of hunger and produces satiety leading to weight loss.”

Seems to me like another classic case of conventional healthcare proposing surgery or medications to address the obesity epidemic. Pharmacologic treatment and bariatric surgery have been offered for years to win the battle of the bulge. As a registered dietitian, who years ago begrudgingly counseled patients prior to undergoing bariatric surgery, I have seen countless people re-gaining all (if not more) of the weight lost after the first year of surgery. Same goes for pharmalogical interventions, such as Phentermine. Sure it worked in the short-term. But in every single case, when the medication was stopped, as it is not FDA approved for long-term use, the weight came creeping back.

My take on the releasing a significant amount of weight does not require going under the knife. How about this instead? Address the cause of increase hunger and appetite. This is a crucial missing link for many undergoing surgery or using medication(s) as a “solution”. Not addressing the cause of increased hunger and ravenous eating behaviors precipitously results in rebound weight gain. Rather than sending an electrical pulse to a nerve in the stomach, maybe the FDA should consider a Cureality-based nutrition program that is wildly successful stimulating a “side effect” of weight loss. Wheat elimination offers a surgery-free option that reduces hunger and insistent drive to eat every few hours, thanks to freedom from gliadin driven appetite stimulation. Weight loss is common experience due to reduced hunger and subsequent intake. Give it a try. What else do you have to lose, but some love handles?

Are Your Beauty Products Toxic?

10. August 2014 Lisa G (0)

As a nutritionist and self-care advocate, I am very careful about what I put in my body. Health benefits experienced through proper nutrition are well understood. We avoid highly processed foods, wheat-based products, and sugary snacks because we know that are “unhealthy” for us. But what about what we put on our skin?

An important piece of the health and wellness puzzle is not only what is on the end of our fork but on our toothbrush, slapped on our bodies and rubbed into our hair. Skin is the largest organ and what we place on it on a daily basis penetrates the skin, enters the fat stores and contributes to the toxicity and adiposity of our bodies. According to the Environmental Working Group, the average woman uses 12 beauty products per day, containing about 168 ingredients. Yikes!

I’ve often held a high suspicious that endocrine disruptors such as parabens, triclosan, fragrance, and other punitive chemicals are a key suspect in the root cause of my endocrine disruption. Interestingly, scientific evidence is now emerging to support this suspicion.

A few months back, I took a look at my hair, skin, and cosmetic products. I was shocked and horrified. Parabens, an estrogen-mimicking preservative linked with endocrine disruption, was in dozens of products. It reminded me of how I felt on that day years ago when I threw out all the products in my kitchen that contained wheat. What are parabens not in? Why was it in so many products?

In our next episode of Cureality Connections we will discuss key skin and beauty product chemicals to avoid along with other steps to take to attain beauty from within.

Top 3 Strength Training Exercises for Runners

28. July 2014 Amber B (0)

First and foremost, if you’re a runner and you’re not strength training you need to start. This in and of itself could be an entire blog article. But here I go with the synopsis.

Strength training will indirectly help you run longer and faster. Strength training exercises can improve your running mechanics, so that you run more efficiently. Efficient running mechanics will lead to less wasted energy with each step and less injuries.

Think about it. You will take 80 to 90 steps per foot each minute you run. If you have muscular imbalances that lead to joint mobility or stability issues you will move through an improper range of motion with each step.

When you run for 30 minutes you take 2700 steps with each foot for a combined 5400 steps. That could be 5400 steps of feet rolling in, rounded shoulders, wasted side to side movement or just pure pain. Needless to say, when you are an endurance athlete it’s important that each step and every workout is adding to improved performance not to injury or fatigue.

The key to becoming a better runner is consistency. For most runners, injuries are the biggest disrupter of consistent training. Runners get a few good weeks or months of training, and then they are injured. That means time off, loss of motivation, and a decrease in fitness.

Strength training with proper form 2 to 3 times a week will reduce the onset of injuries and improve your running form. Here are my top 3 strength training exercises for runners.

Bulgarian Split Squat

You will need a bench, chair or stepper to perform this exercise. Start by doing this exercise with just body weight and then progress. The progression could include holding dumbbells, kettlebells or a barbell. You can also make this exercise explosive.

Place the to top of your back foot on. If you are having a hard time with balance, flex your back toes and place them on the bench.
Stand in a staggered stance about 2 to 3 feet wide. This should allow your knee to bend while keeping your knees behind your front toes.
Inhale as you begin to bend both knees.
Focus on your back knee pointing straight down toward the ground and your body weight in your front heel.
Keep your front kneecap inline with the 3rd toe of the front foot.
Exhale as you straighten both knees to come back up to standing.

Start with 10 repetitions on each leg and progress to 15.

Calf Lowers

Use a stair or a stepper to perform this exercise. Start by doing this exercise with just body weight. The progression would include holding a dumbbell in one hand.

Place the ball of your foot on the stair while holding on to the wall or railing.
Rise up on the ball of your foot as high as your heel will go. Make sure you have weight evenly distributed on all of your toes and that you are not rolling onto one side of your foot.
Slowly, lower you heel back to the starting position. Try counting 3 to 5 slow counts to ensure you really focus on lowering part of the movement.

Do 10 reputations on each foot to start. Work up to doing 20 reputations on each foot.

Band or Cable Row

How many runners do you see hunched over logging long miles. This exercise is for improved running posture, which can lead to improved respiration.

To perform this exercise, use a band or a cable. This exercise can be done with both arms or with just one arm.

Stand in a staggered stance with relaxed knees. Make sure your ribs on stacked on top of your hips to ensure good posture.
Grab the handles of the band or the cable in the thumbs up position.
Start the movement by protracting the shoulder blades.
Then bend the elbows straight back so that your biceps are close to your rib care. Keep your knuckles forward.
To release, begin to straighten your elbows and bring your shoulders back to the starting position.

Start with 10 repitions and work up to 20. To increase difficulty, use a more difficult band or more weight on the cable system.

Here’s to improving your running mechanics so that you can train more consistently. Can’t wait to hear about the PR at your next race.

How did Cureality get its start?

27. July 2014 William Davis (0)

In the Cureality program, we embrace information and strategies that empower you in health without drugs, without hospitals, without procedures. We convert your doctor from director of healthcare to your assistant in health. He or she is there when you need help, but you largely direct your own health future.

How did we gain the know-how, information, tools, even chutzpah to take on such an ambitious project?

It started around 10 years ago with the awkwardly named Track Your Plaque program. In fact, some of the current followers of the Cureality program are former Track Your Plaque members, having learned of the wonderful list of strategies that can be adopted to gain better control over, even reverse, coronary atherosclerotic plaque and risk for heart attack. They also learned that something special happens when you engage with other people with similar interests, all sharing ideas, insights, and resources to get the self-directed health job done. Over time, what started out as simply a source of better information for coronary health evolved into a self-directed coronary disease management program. We never set out to create something as wildly ambitious as a do-it-yourself-at-home coronary disease risk management program, but that is how it inadvertently turned out.

How we went from Information Provider to Health Empowerment Program

So we never intended to take on something so seemingly impossible as managing coronary risk on your own. But, because we armed people with such empowering, profound insights into better ways to manage their heart disease risk beyond “don’t smoke, cut saturated fat, be active, and take a statin drug”—the typical advice offered by doctors—they returned after an interaction with their doctors disappointed: doctors often declared such strategies unnecessary, or the doctor didn’t understand them—even when there were clear-cut clinical data already available to support their use. In other words, the patients—everyday people, not experts—knew more than their doctors.

This flip-flop in the balance of knowledge made for some very interesting stories, like “Harold” (not his real name) who, having survived a heart attack and received a stent, was told by his doctor to cut his fat intake, eat more whole grains, exercise, take aspirin and a beta blocker drug, and reduce his cholesterol values with a statin drug. Upon learning all the additional information from the Track Your Plaque program, Harold returned to his doctor and asked “I’m not so ready to just go along with this idea of ‘reducing cholesterol’ to address heart disease risk. Because my goal is to gain as much control over coronary disease as possible, maybe even reverse it, I’d like to address some additional issues that I believe may be important. I’d like to have my advanced lipoproteins drawn to measure the proportion of small LDL particles I have, whether I have lipoprotein(a), an omega-3 fatty acid index and 25-hydroxy vitamin D level, and a thyroid assessment. Oh, and I believe I should also have an assessment of my inflammation status, perhaps a c-reactive protein and phospholipase A2, and my blood sugar status measured with a fasting glucose, insulin, and hemoglobin A1c.” Harold’s doctor was dumbfounded and speechless. Rather than reveal his ignorance, his doctor advised Harold that none of that was necessary, sending him on his way and telling him that he was fine.

But this left Harold with a sour taste in his mouth, having engaged in many online discussions with people who had followed conventional advice that resulted in more heart attack, more heart procedures—the conventional answers simply did not work. He also discussed his situation with people who had successfully obtained the additional information he sought, added it to their program and enjoyed dramatically improved health, including freedom from more heart attacks, heart symptoms, and heart procedures, as well as improved overall health. So Harold found an easy way to obtain the testing on his own. Within a couple of weeks, he returned to his online community and shared all his information. Within moments, he was provided useful discussion to help him understand the values, all leading to changes in nutrition, nutritional supplement choices, how and where to get the simple tools necessary, such as iodine and vitamin D supplements. He even entered his data, choosing which values he was willing to share with others, which remained private, allowing him to compare his own follow-up values several months later. Engaged in this process, self-directed but collaborative, he witnessed marked transformations in his health. Not only did he never again—over several years—ever re-develop heart symptoms nor require any more trips back to the cath lab, he lost weight, reversed a pre-diabetic sugar profile, improved his cholesterol values without drugs, got rid of the acid reflux symptoms he endured for many years, dropped his blood pressure to normal, enjoyed better mood, energy, and sleep. Slender, healthier, all accomplished without his doctor.

Harold returned to his doctor for a routine follow-up. Slender, energetic, without complaints, on no drugs except the aspirin for his stent, the basic laboratory assessment his doctor ordered in front of him, his doctor admitted,” Well, I don’t know how you’re doing it, but these values look like a 20-year old substituted his blood for yours. They’re unbelievable. What drugs are you taking to do this?” “No drugs,” Harold replied, “I’m following a program to reverse heart disease, but it means doing some things that are different from conventional solutions.” His doctor closed their meeting with the signature response of doctors nationwide: “Well, I don’t understand what you are doing, but just keep doing it.”

Yes, Harold knew more about how to control heart disease than his doctor, more than his cardiologist. The cardiologist knew how to insert a stent or defibrillator. But deliver information that empowered Harold in all aspects of health from head to toe, while also dramatically reducing, perhaps eliminating, his coronary disease risk? As you now know, that is not what conventional healthcare does, nor is it interested in doing so, as it would relinquish control and threaten to cut off this hugely profitable revenue stream that drives “healthcare.”

Having managed to inadvertently create a self-directed coronary risk management program with such spectacular results and in probably one of the most difficult areas of all—heart disease—it became clear that a similar approach could be even more easily applied to many other areas of health, such as weight loss, bone health, cholesterol and blood pressure issues, diabetes and pre-diabetes, hormonal health, autoimmune conditions, and others. You can do it when empowered by safe, effective information, and supported by a community of sharing and collaboration. We don’t fire our doctors; they are there when we need them when, for instance, we get injured or catch pneumonia, or as an occasional resource. But doctors should no longer be able to get away with neglect, misinformation, or blindly directing you to the next revenue-generating procedure because you are empowered by the information and support you receive in Cureality.

As we get more effective in delivering this information and new tools to you, just imagine what we can accomplish in this new age of information and self-empowerment. The future for us is bright with ambitions for better interactive tools with Cureality expert staff, better ways to crowd source health answers, provide more engaging community conversation, all while the health insights that help accomplish our self-directed health goals get better and better. Each person that joins Cureality helps make this service more effective because your wisdom, insights, and experience are added to the collective knowledge. We are more powerful together than we are as individuals.

Sit Less and Move More.

21. July 2014 Amber B (0)

We sit way too much. Many of us have desk jobs where we sit for 8 to 9 hours a day. After we leave the office, we sit in our car to run errands. We follow that by sitting down to eat dinner. Our day ends by sitting on the couch to unwind by watching some television.

Many of us will be sitting a good 12 to 15 hours each and every day. Unfortunately the research shows that long hours of sitting can lead to obesity, heart disease, diabetes, and even early death. Don’t be fooled that your workout is enough movement. You can still be active and sedentary.

How can you add more movement to your day? First, think about all the times you find yourself sitting during the day. Then come up with a creative way that you can get out of the seat and move your feet.

Here are a couple of examples:

Instead of driving everywhere, jump on your bike. The picture above is of the bike I use to go to work or run errands. Bike riding is great exercise, greener transportation and a great stress relief.

We spend a lot of time at work sitting in front of the computer or the phone. Prop your laptop on a bookshelf to create a standing workstation. You can also purchase a sit-stand workstation you can adjust throughout the day. Get a headset and stand during phone calls.

Walk during your lunch break. Walk to the coffee shop, the mailbox, and the dry cleaners. Get your errands done on foot or just enjoy a stroll outside.

Take a movement break every hour. Do some desk push-ups, squats or walk the stairs. Need to communicate with a coworker? Don't email, walk over and talk to them.

Human beings are meant to move, not sit in chairs all day. I want to challenge you to incorporate more movement into your day. I'd love to read your comments how you move more and sit less.

Have You Had Your Prebiotics Today?

11. July 2014 Lisa G (0)

Prebiotics and resistant starch may be the missing link to your digestive health. Indigestible fibers that allow healthy bowel flora to proliferate and thrive are often called prebiotics. They are also known as resistant starches, because they are resistant to human digestion. I recently had a client call the addition of resistance starch to her diet, “the missing link my body needed”.

A starch that resists digestion and reaches the large intestine becomes food for the healthy bacteria in the large intestine. These bacteria can break down and “feed on” the resistant starch thus providing the friendly bacteria with the fuel they need to survive.

Imbalance of the quantity and type of bacteria species present in the gut contributes to gastrointestinal illness, blood sugar imbalance, obesity, mood disorders, and immune system challenges.

Green unripe bananas and plantains are one of best sources for prebiotic fiber content with 27 to 30 grams of fiber in one medium banana. Green bananas are essentially inedible. They are most easily incorporated into diet by blending into a smoothie.

One mistake frequently made incorporating prebiotic fibers from bananas is consuming bananas that are too ripe. Once the banana ripens the resistant starch is degraded and become a digestible starch. Thus, no longer a good prebiotic fiber source. In fact, the riper the banana becomes the higher the glycemic (blood sugar) response.

It can be difficult to find bananas that are very green. I made several trips to my local grocery store to find these bowel flora champions. I find it helpful to ask the produce clerk to take a look at the shipment that just arrived, noting the day the shipment arrives, for the best chance to gobble up these green beauties.

In an effort to keep green bananas green I tried a few strategies. One that sounded promising was wrapping the end of the banana to prevent the ethylene gas, which ripens the fruit, from dissipating. You can see from the image this clearly did not work. After a mere two days the green bananas were no longer green. What I found works best is placing the green bananas in the fridge. This halts the ripening process. The skin of the banana will turn brown, which is normal, but the fruit inside is still good. I’ve kept bananas in my fridge for up to 8 days and they hold up well other than the brownish black discoloring that develops on the skin. The banana will be firm and require a knife to cut the skin off the banana.

If you’d like to learn more about prebiotics and strategies to support resolution of common gastrointestinal complaints read the recently release Cureality Guide to Healthy Bowel Flora by Dr. Davis. This guide is one of the many valuable resources available exclusively to Cureality.com members.

Something is Better Than Nothing

2. July 2014 Amber B (0)

This past weekend I attended a fitness conference with an amazing lineup of presenters. Even after 11 years in the fitness industry, I love attending these events. I’m a lifetime student always learning more and honing my craft.

I went to a presentation by Al Vermeil about joint mobility, not knowing anything about him. To my surprise, Al was the strength and conditioning coach for the Chicago Bulls and the San Francisco 49ers the years these teams won championships in their respective sports. That’s a pretty impressive resume.

Al was a great presenter, full of fun and practical advice. During his presentation, Al said the following statement:

“Every time you miss a workout, the next one is easier to miss.”

This statement really hit home because I’ve seen this time and time again working in the fitness industry and in my own life. One workout is missed, then an entire week of workouts are missed, then it’s been an entire month of never setting foot back into the gym.

It’s easy to get thrown off your workout routine when life gets busy and days get long. So what do you do? Do you just trash your workout plan?

The all or nothing attitude is common when it comes to making health changes. Either you’re following your plan 100% or you not. I’m here to tell you that doing something is better than nothing. Doing part of your workout or a mini workout is better than missing an entire workout.

The other day I had the choice to do something or nothing. I had a full day of work meetings, video, and family commitments. Here is what happened. I did shorter variation of my joint mobility routine. I followed that with a quick kettlebell circuit of 25 kettlebell swings, 12 kettlebell overhead presses, and 12 kettlebell goblet squats. I did three rounds of this circuit. That’s it! The following day, I got back to my regular exercise routine.

Be consistent with movement and you’ll always see improvements. That’s the magic of exercise. You'll get better if you just do it.

What’s the Problem with My “Healthy” Bowl of Oatmeal?

26. June 2014 Lisa G Nutrition, Oatmeal (0)

Food manufacturers have clever ways to market foods to us. Unfortunately, many foods that have a reputation for being healthy are no more than junk food disguised as a healthy food choice. I commonly see people under the influence of a “health halo” effect. This is due to strategic marketing efforts. People overestimate the nutritional value of a food that is labeled “good for you” or they underestimate the negative impact of a food because it contains a healthful ingredient, like flaxseed or fiber. In fact, a recent study from the University of Houston found that terms on food labels such as antioxidants, all-natural, and gluten-free often are used to give an otherwise standard food a "healthy" halo, and influence consumption from the well- intended consumer.

Case in point-- oatmeal. We’ve all heard about the cholesterol lower benefits from soluble fiber contained in oatmeal. It’s blasted all over packages with a paid endorsement from The American Heart Association. However, that’s not the whole story. Most people enjoy a cup of oatmeal with one to two tablespoons of added sugar and fruit such as a ripe, yellow banana. In other words, let’s enjoy a bowl of “send my blood sugar through the roof” high glycemic oatmeal. The glycemic index of oatmeal is 55, and instant oatmeal is 83. Top that with more table sugar, glycemic index 58-65 and better yet top that with a high glycemic, ripe banana with a GI of 62.

Preparing one packet of regular instant oatmeal with one tablespoon of sugar and a medium ripe banana five days per week would result in the sugar equivalent of more than 5 1/2 cups of sugar per month!

Furthermore, the story many Americans are missing is all of that sugar intake, from their so-called “healthy” bowl of oatmeal, actually raises small-dense LDL cholesterol particles, increases blood sugar and contributes to insulin resistance, faulty gut flora, and belly fat.

How do we improve upon our bowl of oatmeal? Enjoy a bowl of hot coconut flaxseed cereal, eggs any variety of ways, or last night’s leftover salmon and vegetables.

The Cureality program provides tools, guidance, and support that does not follow the party line but rather offers nutrition solutions that address the underlying causes for proliferation of many chronic diseases.

Power in Numbers

25. June 2014 William Davis (0)

In his book, The Wisdom of Crowds, author James Surowiecki begins with the story of an ox judging competition in which 800 people—not ox experts nor breeders, just ordinary people attending a county fair—were asked to guess the weight of the ox. The competition was conducted by a scientist, Francis Galton, who held a low opinion of the intelligence of the average person, remarking that “the stupidity and wrong-headedness of many men and women being so great as to be scarcely credible.” He hoped to prove, by examining the various guesses, that the average person had no idea of how to judge the real answer. After all participants casted their written votes, Galton tallied up the total and averaged the result: 1,197 pounds—just one pound off from the real weight of 1,198 pounds. Few individuals actually guessed the correct weight themselves but, when the opinions of many were combined, the result was near-perfect.

Crowds can also be a source of irrational behavior, panic, and stampede. Witness any modern football or soccer game, for instance, in which fights break out over an issue as minor as a disputed call or a heckle. Or go back through history to the countless events when mass hysteria ruled, such as the Salem Witch Trials or Orson Welles’ War of the Worlds radio broadcast.

Let’s put aside examples of mass emotional chaos of the sort that causes crowds to stampede store doors on Black Friday. Let’s focus instead on conscious, considered, thoughtful opinions. We all accept that there are as many opinions on issues as there are people, not uncommonly with widely divergent views. But can we, as Galton’s famous experiment did, combine the opinions of many and come away with some fruitful insight—the correct answer? Just as the people participating in Galton’s experiment were not experts, so Cureality participants—a crowd-sourced collection of opinions—are not experts. If we were to poll everyone to identify their area of expertise or experience, it would likely include finance, the retail industry, raising children, or teaching—but not health. Yes, we have experts curating the direction of content, but we also crowd-source collective opinion.

Right now, Cureality is based on existing science, the philosophy of self-directed health, combined with guidance and community to help the participant along in the sometimes complex world of health questions. But as our processes and procedures improve, can we—like Galton’s ox weight guessers—come away with coalescent wisdom, answers to our health questions, near-perfect solutions to health conditions that have eluded the “experts” for centuries?

I think that we can. No, I know that we can. We enter a new age in information and harness the power of the crowd-sourcing of solutions, even when no single individual has the complete answer herself.

Use This Trick to Boost Exercise Motivation

23. June 2014 Amber B (0)

Are you been struggling to get your workouts in?

Do you belong to a gym and find that you're not going?

Do you have exercise equipment sitting in your basement collecting dust because you find that you just can’t get yourself down there?

If you answered, “yes” to any of these questions you are not alone. Many people struggle with finding the motivation to exercise.

The problem here is that you have head trash going on. Head trash is that voice inside your head coming up with a million excuses that inhibit you from carving out a bit of time to take care of yourself.

Head trash will tell you that you’re too tired, even though a workout would give you a boost of energy.

Head trash will tell you that you’re too busy, even though you just spent a half hour on Facebook.

Head trash is barking at you to take care of others, even thought you know your health is important for you well being.

Head trash is a real conflict that can get in the way of our health and fitness goals. We start an exercise program with the intentions of a long-term commitment. But after the initial excitement wears off, we find our workouts occurring less frequently. Head trash begins to take over and soon we find ourselves not exercising at all.

Here is my secret for winning the battle over the head trash that keeps getting in way of your workouts. Tell yourself that you are only going to exercise for 10 minutes and evaluate if you want to continue. If you're truly too tired you can stop after 10 minutes. If you're truly too busy you can stop and move onto a task that needs your attention.

Making this deal with your mind that you are only going to exercise for 10 minutes seems reasonable. The head trash will become quite because your mind is convinced it has an out within 10 minutes.

I've used this 10-minute trick myself. I grind through the first few minutes, but then the magic happens. Once you hit the 10-minute mark your body takes over. Exercise feels amazing and your body is energized and enjoying the movement. You have tricked your mind to get over the hurdle of starting and now you’re in the exercise groove.

Try the 10-minute trick next time your head trash is getting in the way of your workout. You'll be amazed how your workout consistency improves.
