Addictive Foods

25. June 2007 William Davis (3)

Kraft Foods, Inc. is manufacturer of Kool Aid, Oscar Mayer, Kraft Macaroni and Cheese, Velveeta, Honey Maid Grahams, and hundreds of other processed food products. Post cereals also falls under the umbrella of Kraft with products like Raisin Bran, Post Toasties, and Fruity Pebbles. Annual revenues in 2006 for Kraft: $34.4 billion. A big operation with enormous influence over our eating habits.

Nabisco is manufacturer of Oreos, Ritz Crackers, Chips Ahoy and many others. Like Kraft/Post, it is also a big player.

While Nabisco was owned for several years by tobacco giant RJ Reynolds, in 2000 it was acquired by Philip Morris, another big tobacco manufacturer.

More recently in Spring, 2007, Philip Morris (now called Altria--you'd change your name, too, if it was synonymous with dirt) spun off its Kraft subsidiary for a big profit. However, the management structures remain intertwined.

In other words, despite the shuffling of shares, the two industries, big tobacco and big food, are in many respects one and the same.

Is it any surprise that the same industry that made billions of dollars pushing addictive nicotine products responsible for the deaths of hundreds of thousands of people is now intimately involved with addictive products produced and marketed by the processed food industry?

If you believe that food manufacturers are innocently and honestly conducting their businesses, simply think back to the testimony provided in front of Congress during the tobacco industry hearings. Broad deception, concealed truths, and outright lies were commonplace. There was no conscience involved. This was about money--and lots of it.

Why should the processed food industry, intimate with the tobacco industry, be any different?

If you want control over heart disease and your heart scan score, buy produce and buy local. Spend your time in the produce aisle, not the cereal or chip aisle. Unprocessed food, unadorned by bright labels, cartoon animals, American Heart Association endorsements, that's what we should seek.

Heart Scan Curiosities #7

25. June 2007 William Davis (1)

Here's a situation that crops up once in a while, occurring in perhaps 2% of heart scans.

The white within the circled area represents calcium, and thereby atherosclerotic plaque, situated immediately at the "mouth", or opening, of the the right coronary artery. What is somewhat unusual is that this plaque is not principally coronary, but aortic. That is, the plaque is mostly situated in the large vessel called the aorta. The three coronary arteries arise from the aorta.

In this instance, the aortic plaque involves the mouth of the right coronary artery. (In views not shown, the plaque also extends into the artery as well.) I call this a "double whammy" because the same plaque can post risk for heart attack and stroke.

Generally, aortic plaques pose risk for stroke. When aortic plaque fragments, little bits and pieces can travel upward to the brain and block an artery, thus a stroke.

In the coronaries, disrupted ("ruptured") plaques don't generally shower debris, but permit blood clot formation, resulting in heart attack.

This plaque, however, poses the theoretical risk of both heart attack and stroke because of its strategic location.

Should a plaque like this be handled any differently? I don't think so. But it does provide another reason to take atherosclerotic plaque in any artery seriously.

The nutrition counterculture

23. June 2007 William Davis (2)

When we look back over our American nutritional history over the last 50 years, it's hard not to come to the conclusion that much of the innovation in nutrition did not come from official agencies like the Food and Nutrition Board of the Institute of Medicine, the National Academy of Sciences, the FDA, the USDA, or the AMA.

Instead, it came from the popular culture. It came from bold, extravagant claims made by maverick figures like Ancel Keys, Nathan Pritikin, Dean Ornish, and Robert Atkins. Of course, some ideas have now fallen by the wayside, dismissed in a broad American "experiment" as ineffective, impractical, or kooky. But it permitted experimentation on an extraordinary scale with millions of people following a particular strategy at a time.

The advice of the official agencies tended to be reactionary. When nutritional deficiencies (remember those?) of the early 1900s were prevalent, they issued advice on food choices to help alleviate deficiencies. When deficiency transformed into excess after World War II, "smart" food choices from food groups and "sensible eating" became the theme.

Unfortunately, the advice was always adulterated by the enormous influence of various special interests, anxious to protect their national franchise. Powerful groups like the meat industry, wheat producers, and the dairy industry all made sure they had a big hand in crafting and influencing what was told to the American people.

The result: the advice offered by official groups has always represented the compromise of what some agency wished to convey to the people and the very powerful input of industry. What if the government decided to advise us what automobile to buy? Imagine the uproar in the auto industry when Washington tells us to buy Toyota for fuel economy and reliability. How long would that advice last?

That's why almost no knowledgeable adult follows the advice of the USDA, the National Academy of Sciences, or the Food Pyramid. I believe that we all intuitively recognize that the advice is watered-down, sometimes silly, sometimes downright unhealthy.

Nonetheless, the national experiment in diet that has taken place since 1950 has led to a collective wisdom of what is good and what is bad. The most productive conversations on nutrition therefore take place outside of the USDA and Washington. It occurs, instead, in places like bookstores, websites, and the media. Of course, there's lots of misinformation and profiteering in these sectors, as well. But like the enormous force unleashed by the collective wisdom of those contributing to the Wikipedia phemonenon, we've zig-zagged to something closer to the truth than ever uttered by an official agency.

Prescription vitamin D

23. June 2007 William Davis (32)

Niacin:

Over-the-counter: $2-5 per month
Prescription: $120 per month

Fish oil:

Over-the-counter: $3-6 per month
Prescription: $120 per month

Vitamin D:

Over-the-counter: $2 per month
Prescription: $70 per month

With vitamin D in particular, the prescription form is vastly inferior to the over-the-counter preparation. This is because the prescription form is ergocalciferol, or vitamin D2, not the effective human form, vitamin D3 or cholecalciferol.

When you're exposed to sun, what form of vitamin D is activated in the skin? It's all vitamin D3, no vitamin D2 whatsoever. Vitamin D3 is also far more effective than D2. People taking D3 (as long as it's oil-based) easily obtain healthy levels of vitamin D in the blood. People taking 50,000 units per day of D2 (the recommended quantity) remain miserably deficient, with minor increases in vitamin D blood levels. In short, D2 barely works at all. D3 works easily and effectively.

Moreover, D2 is the plant-based form. It is a form not found naturally in humans. D3 is the mammalian form, the same found in humans that exerts all its biologic benefits.

Then why is the prescription form of vitamin D2 (brand names Driscol and Calciferol) more expensive?

It's the same old pharmaceutical industry scam: Look for something patent protectable, regardless of whether it's superior to the non-patent protectable product, then sell it for exagerated profits. Though it is inferior and the science and clinical experience prove that it's inferior, you can still fool lots of people, including prescribing physicians. So what if you only make $50 or $100 million?

Don't fall for it. Prescription doesn't necessarily mean superior. In fact, the prescription form may be significantly inferior, as with vitamin D2. But the pharmaceutical industry carries such power and persuasion, who's going to know?

Nutrition activist Mike Adams

20. June 2007 William Davis (1)

I borrowed the above comic from the website of nutritionist, more properly nutrition activist and author, Mike Adams. His website, www.newstarget.com, was a pleasant surprise.

I was actually looking for some thoughts on pharmaceutical advertising and its pervasive and destructive effects and came across one of Adam's reports, Pharmaceutical television advertising is a grand hoax at http://www.newstarget.com/021526.html. The piece is a rant against the pharmaceutical industry's constant bombardment of the media, who have also been co-opted into their service, enticed by the enormous advertising revenues the drug industry brings.

But I was surprised to find an insightful, informative website on health issues, particularly healthy eating that rejects the manufactured food industry's intensive effort to persuade us to eat their products. While I don't agree with everything Adams has to say, his website provides some great food for thought. He also provides lots of downloadable information.

There's also some great laughs at his poke at the pharmaceutical industry with his Disease Mongering Engine at http://www.newstarget.com/disease-mongering-engine.asp, in which you get to create your own diseases. I got a real kick out of this.

CT scans and radiation exposure

19. June 2007 William Davis (8)

The NY Times ran an article called

With Rise in Radiation Exposure, Experts Urge Caution on Tests at

http://www.nytimes.com/2007/06/19/health/19cons.html?_r=1&adxnnl=1&oref=slogin&adxnnlx=1182254102-vQpytpx6W/Z9gvAaNPDZvA

“This is an absolutely sentinel event, a wake-up call,” said Dr. Fred A. Mettler Jr., principal investigator for the study, by the National Council on Radiation Protection. “Medical exposure now dwarfs that of all other sources.”

Where do CT heart scans fall?

Let's first take a look at exposure measured for different sorts of tests:

Typical effective radiation dose values

Computed tomography Milliseverts (mSv)

Head CT 1 – 2 mSv
Pelvis CT 3 – 4 mSv
Chest CT 5 – 7 mSv
Abdomen CT 5 – 7 mSv
Abdomen/pelvis CT 8 – 11 mSv
Coronary CT angiography 5 – 12 mSv

Non-CT Milliseverts (mSv)

Hand radiograph Less than 0.1 mSv
Chest radiograph Less than 0.1 mSv
Mammogram 0.3 – 0.6 mSv
Barium enema exam 3 – 6 mSv
Coronary angiogram 5 – 10 mSv
Sestamibi myocardial perfusion (per injection) 6 – 9 mSv
Thallium myocardial perfusion (per injection) 26 – 35 mSv

Source: Cynthia H. McCullough, Ph.D., Mayo Clinic, Rochester, MN

If you have a heart scan on an EBT device, then your exposure is 0.5-0.6 mSv, roughly the same as a mammogram or several standard chest x-rays.

A heart scan on a 16- or 64-slice multidetector device, your exposure is around 1.0-2.0 mSv, about the same as 2-3 mammograms, though dose can vary with this technology depending on how it is performed (gated to the EKG, device settings, etc.)

CT coronary angiography presents a different story. This is where radiation really escalates and puts the radiation exposure issue in the spotlight. As Dr. Cynthia McCullough's chart shows above, the radiation exposure with CT coronary angiograms is 5-12 mSv, the equivalent of 100 chest x-rays or 20 mammograms. Now that's a problem.

The exposure is about the same for a pelvic or abdominal CT. The problem is that some centers are using CT coronary angiograms as screening procedures and even advocating their use annually. This is where the alarm needs to be sounded. These tests, as wonderful as the information and image quality can be, are not screening tests. Just like a pelvic CT, they are diagnostic tests done for legimate medical questions. They are not screening tests to be applied broadly and used year after year.

Always be mindful of your radiation exposure, as the NY Times article rightly advises. However, don't be so frightened that you are kept from obtaining truly useful information from, for instance, a CT heart scan (not angiography) at a modest radiation cost.

Detail on radiation exposure with CT coronary angiograms on multidetector devices can be found at Hausleiter J, Meyer T, Hadamitzyky M et al. Radiation Dose Estimates From Cardiac Multislice Computed Tomography in Daily Practice: Impact of Different Scanning Protocols on Effective Dose Estimates. Circulation 2006;113:1305-1310, one of several studies on this issue.

Mediterranean diet vs. American Heart Association Diet

18. June 2007 William Davis (4)

In 1994, the Lyon Heart Study demonstrated a 50-70% reduction in coronary events in participants who followed a diet rich in vegetables, olive oil, fish, nuts, red wine, and enjoyed meals as a family activity. Various other studies have documented similar phenomena with less metabolic syndrome, better lipid patterns, less obesity with the Mediterranean lifestyle.

There are two fundamental differences between the Mediterranean diet and the diet advocated by the American Heart Association (AHA) for people with heart disease: the Mediterranean diet uses olive oil more liberally, such that fat calories can reach 40% of total; and, unlike the AHA diet, processed foods are not a part of the Mediterranean diet. Greeks, for instance, are far less likely to eat Count Chocula cereal for breakfast, or snack on Healthy Choice Premium Caramel Swirl Sandwich (ice cream sandwiches) or Malt-O-Meal Honey Nut Scooters. All three of these foods on listed on the AHA Heart-Check Mark heart-healthy program.

In other words, remove all the processed foods, and the AHA diet pretty closely resembles the Mediterranean diet. There are differences but they tend to be relatively small. If the only major difference is the presence of processed foods, wouldn't you therefore expect the AHA to embrace the Mediterranean diet?

Here's what their official stand on the Mediterranean diet states:

Does a Mediterranean-style diet follow American Heart Association dietary recommendations?

Mediterranean-style diets are often close to our dietary recommendations, but they don’t follow them exactly. In general, the diets of Mediterranean peoples contain a relatively high percentage of calories from fat. This is thought to contribute to the increasing obesity in these countries, which is becoming a concern.

The AHA is actually lukewarm towards the diet that was the first to show a dramatic decrease in heart attack and death. Why?

The answer is obvious, once cast in this light. To wholeheartedly endorse the Mediterranean diet might be seen as an indirect rejection of American processed foods. You know, the foods that have caused an extraordinary and unprecedented epidemic of obesity in the U.S., the foods that are manufactured by ConAgra, General Mills, Kelloggs--all also major financial contributors to the AHA, according to the AHA Annual Report.

I tell my patients: If you want heart disease, follow the American Heart Association diet. In my view, it is a diet founded on politics and money, not on health. How else could Cocoa Puffs be regarded as heart healthy?

Track Your Plaque in 50,000 BC

16. June 2007 William Davis (3)

Imagine we could send you back in a time machine to 50,000 BC.

However, our agreement: no modern tools or equipment. Just your brain, hands, and legs. And your landing spot will be tropical or semi-tropical, the same climate that humans spent much of their evolutionary time in.

Not only might you rub elbows with contemporaries like homo erectus and neanderthalensis, you'd also have to fend for your life and survival.

To eat, you will have to chase and kill wild game, all with your bare hands or crude tools crafted from sticks and stones. You will have to learn what wild berries, roots, and plants are edible and distingusih them from those that make you retch, make your bowels run, or kill you. You won't be able to cultivate grain, at least for a good long time, since you don't have a community that makes such an undertaking easier.

Instead, you are constantly on the run, from the moment you awake until you finally settle back as the sun sets, hopefully with a full stomach, but often empty and growling, anticipating the hunt and forage of tomorrow.

You are outdoors all day, except for the period when you hide in your cave or self-made shelter. You wear what little clothing you can make yourself from your kills, a skin or two. Your skin becomes a dark brown, a 5 foot 10 inch male will weigh 140 lbs, a 5 foot 5 inch woman 95 lbs. There are obvious downsides: your teeth will rot, you will be prone to infections, and predators view you as fair game.

But the result will be that many chronic diseases of modern life will no longer be worries for you. Heart disease? Highly unlikely. Do you need vitamin D? No, because you are outdoors virtually all day with most of your body surface area exposed to sun. Omega-3 fatty acids? You get those from the wild game you eat, since they have higher omega-3 content feeding in the wild, not eating corn like modern livestock. Since your body fat is minimal, just enough for survival, you don't need niacin.

In other words, many of the strategies of the Track Your Plaque program are modern necessities, responses to the "deficiencies" of modern life. Of course, I don't really have a time machine. I also doubt that you wish to hunt wild game every day, forage for plants and roots, run nearly-naked in the sun. You probably also have become accustomed to brushing your teeth and not viewing every animal as a potential threat to your life.

Nonetheless, I find this an interesting exercise for understanding the role of all the tools we use in the Track Your Plaque program for plaque control.

When pessimism wins

15. June 2007 William Davis (3)

When I first met Hank, I immediately sensed it: anger, hostility, fear. His heart scan score of 685 just made it worse.

He didn't want to be there talking to me. His wife was giving him a hard time. Work was a constant source of irritation. The receptionist at the front desk screwed up his paperwork. Our office charges were too much.

In short, Hank was a pessimist. A bad one.

All the nutrition information out there is bunk. Only he knew how he should eat right. It's stupid to take a lot of fish oil. "You want me to grow gills?"

Among the parameters we use in the Track Your Plaque program is blood pressure during exercise, which provides a surrogate measure of blood pressure during emotional stress, anxiety, etc. "No, I don't need that. I already exercise." No amount of justification could change his mind. "A guy at work had a stress test. They said everything was fine, then Bang! He drops dead. What good is that?"

Hank did go along with a few pieces of advice.

A repeat heart scan 12 months after the first: 870, a 27% per year rate of increase. That's about what would happen if Hank had done nothing, had taken no action to try and stop or reduce his heart scan score.

I don't know if Hank will ever succeed in dropping his score. In fact, I suspect that he will fail, meaning that plaque will grow and he will eventually, perhaps in a year, two or three, require several stents, heart bypass, or have a heart attack. In other words, Hank's pessimism is a self-fulfilling phenomenon: If he believes he will fail, he will. If he believes the world is a rotten place, it is.

Is it possible to "cure" someone like Hank of his deeply-rooted pessimistic attitudes? I don't know of any easy solutions for someone with attitudes as deeply-ingrained as Hank's. (See my prior post, "Cure for pessimism?" at http://heartscanblog.blogspot.com/2007_05_01_archive.html.)

I believe it does help to make someone aware of their attitudes and that it does indeed exert ill health-effects--if they will believe it. But this is a very tough nut to crack.

Bad news on CoQ10?

13. June 2007 William Davis (8)

A review of the effects of Coenzyme Q10 (CoQ10) on the muscle aches and weakness (myopathy) of statin drug therapy was just published in the Journal of the American College of Cardiology.

(Marcoff L, Thompson PD. The role of coenzyme Q10 in statin-associated myopathy. J Amer Coll Cardiol 2007;49(23):2231-2237.)

This is not a study, but a review of the existing scientific and clinical data available on this topic. The study authors conclude with a lukewarm statement:

". . .there is insufficient evidence to prove the etiologic [causal] role of CoQ10 deficiency in statin-associated myopathy and that large, well-designed clinical trials are required to address this issue. The routine use of CoQ10 cannot be recommended in statin-treated patients. Nevertheless, there are no known risks to this supplement and there is some anecdotal and preliminary trial evidence of its effectiveness. Consequently, CoQ10 can be tested in patients requiring statin treatment, who develop statin myalgia, and who cannot besatisfactorily treated with other agents. Some patients may respond, if only via placebo effect."

Should the media get hold of this report, be prepared for the usual "Nutritional supplement no help for drug toxicity" headlines, or "Yet another nutritional supplement shows no benefit" with parallels drawn to vitamin C or E.

There are several issue that need to be factored into the discussion:

1) This is not a study, just a review. Thus, any biases of the authors are more likely to exert themselves.

2) The understanding of CoQ10 absorption among different preparations may be an issue. I just received a mailing from Life Extension that made extravagant claims about the superior absorption of ubiquinol, to be distinguished from ubiquinone, the more common form. They claim that eight-fold increased absorption and blood levels of CoQ10 are achievable with ubiquinol. Unfortunately, virtually all the supportive data are unpublished, proprietary observations, i.e., generated by companies who make or sell it. This is as reliable as drug manufacturers who publish glowing reports on their own drugs--perhaps it's true, but it requires unbiased corroboration.

3) Despite the lack of a large, well-funded clinical trial (all are small), the issue continues to live and breathe because of the powerful anecdotal experience.

In our experience, CoQ10 does work. It doesn't work all of the time, perhaps just 80-90% of the time. It does generally require higher doses (100 mg per day, occasionally more). It very clearly must be an oil-based gelcap (just like vitamin D) to work; capsules containing powder do not work.

It's difficult to doubt when someone starts a statin drug, develops the muscle aches and weakness, begins CoQ10 and obtains distinct relief, stops CoQ10 and aches and weakness return, then only to go away again with resumption of CoQ10 . I've seen this countless times.

We do need better information on CoQ10. There's no doubt about it. For people who obtain benefit from statin therapy, I think CoQ10 remains a useful solution. A better solution would be to get rid of the offending drug. But that's not always possible--e.g., LDL cholesterol 190 mg/dl despite the best diet and "adjunctive" food effort. Then CoQ10 can be very useful.

Here's Margaret putting the einkorn grain into the electric grinder.

We tried to grind the grain by hand with mortar and pestle, but this proved far more laborious than I anticipated. After about 15 minutes of grinding, this is what I got:

Barely 2 tablespoons. That's when Margaret fired up the electric grinder. (I can't imagine having to grind up enough flour by hand for an entire family. Perhaps that's why ancient cultures were thin despite eating wheat. They were just exhausted!)

We added water, salt, and yeast, then put the mix into an electric breadmaker to knead the dough and keep it warm.

We let the dough rise for 90 minutes, much longer than conventional dough. The einkorn dough "rose" very little. Margaret tells me that most dough made with conventional flour rises to double its size. The einkorn dough increased no more than 20-30%.

The einkorn dough also distinctly smelled like peanut butter.

After rising, we baked the dough at 350 degrees F for 30 minutes. This is the final product.

Because I want to gauge health effects, not taste, the bread we made had no added sugar or anything else to modify taste or physiologic effect.

On first tasting, the einkorn bread is mildly nutty and heavy. It had an unusual sour or astringent taste at the end, but overall tasted quite good.

Next: What happens when we eat it? I'm going to give the einkorn bread (I've got to make some more) to people who experience acute reactions to conventional wheat and see if the einkorn does the same. I will also assess blood sugar effects since, after all, hybridizations or no, it is still a carbohydrate.

Margaret Pfeiffer's book is available on Amazon:

Ezekiel said what?

10. June 2010 William Davis (24)

Some people are reluctant to give up wheat because it is talked about in the Bible. But the wheat of the Bible is not the same as the wheat of today. (See In search of wheat and Emmer, einkorn and agribusiness.) Comparing einkorn to modern wheat, for example, means a difference of chromosome number (14 chromosomes in einkorn vs. 42 chromosomes in modern strains of Triticum aestivum), thousands of genes, and differing gluten content and structure.

How about Ezekiel bread, the sprouted wheat bread that is purported to be based on a "recipe" articulated in the Bible?

Despite the claims of lower glycemic index, we've had bad experiences with this product, with triggering of high blood sugars, small LDL, and triglycerides not much different from conventional bread.

David Rostollan of Health for Life sent me this interesting perspective on Ezekiel bread from an article he wrote about wheat and the Bible. David argues that the entire concept of Ezekiel bread is based on a flawed interpretation.

"I Want to Eat the Food in the Bible."

Are you sure about that?

Some people, still wanting to be faithful to the Bible, will discard the "no grain/wheat" message on the basis of biblical example. After all, God told Ezekiel to make bread, he gave the Israelites "bread from heaven," and then Jesus (who is called the "Bread of Life"!) multiplied bread, and even instituted the New Covenant with what? Bread and wine! If you're going to live the Bible, it seems that bread and/or wheat is going to play a part.

But this is unnecessary. Sure, the Bible can and does tell us how to live, but this doesn't mean that everything in the Bible is meant to be copied verbatim. Applying the Bible to our lives requires wisdom, not a Xerox machine.

The Bible was written in a historical context, and the setting happened to be an agricultural one. Because of this, the language used to describe blessing spoke of things like fields full of grain, or barns overflowing with wheat. Had the Bible been written in the context of a hunter-gatherer culture, the language describing blessing probably would have been about the abundance of wild game, or baskets full of vegetables. Whatever is most valuable in your time and in your culture is a blessing. God accommodated His message to the culture as it existed at the time. This is done throughout Scripture.

There is a danger, then, in merely copying what the Bible says, instead of extracting the principles by which to live. Take the above example of Ezekiel, for instance. There's a whole product line in health food stores called "Ezekiel Bread" that supposedly copies the recipe given in Ezekiel 4:9. This is from the website:

"Inspired by the Holy Scripture verse Ezekiel 4:9., 'Take also unto thee Wheat, and Barley, and beans, and lentils, and millet, and Spelt, and put them in one vessel, and make bread of it...'"

Believing that this "recipe" has some kind of special power just because it's in the Bible is ridiculous. How ridiculous is it? I'll tell you in a moment, but first let me say that this is why it's so important not to confuse descriptives with prescriptives. Is the Bible telling a story, or is it telling us to do something? We would be well-advised not to confuse the two.

In the case of the Ezekiel Bread, what is going on in the passage? There's a siege going on, with impending famine, and Ezekiel is consigned to eating what was considered back then to be some of the worst possible food. It was basically animal chow. But that's not the worst thing going on in this passage. Apparently, when the makers of Ezekiel Bread were gleaning their inspiration for the perfect recipe, they stopped short
of verse 12:

"And thou shalt eat it as barley cakes, and thou shalt bake it with dung that cometh out of man, in their sight."

Um...what? Well, there was a good reason for this. God was judging His people, and by polluting this really bad bread with dung (which was a violation of Mosaic law; Lev. 5:3), He was saying that they were no different from the unclean Gentiles.

So why would we take this story and extrapolate a bread recipe from it? Beats me. If you were going to be consistent, though, here's what you'd have to end up with:

Let that be a lesson to you. We don't just go and do everything that we see in the Bible.

Low-carb gynecologist

6. June 2010 William Davis (36)

I met infertility specialist, Dr. Michael Fox, on Jimmy Moore's low-carb cruise just this past March.

Dr. Fox is quiet and unassuming, but had incredible things to say about his experience with carbohydrate restriction in female infertility and pregnancy. While readers of The Heart Scan Blog already know that I advocate a diet free of wheat, cornstarch, and sugar for heart health and correction of multiple lipoprotein abnormalities, it was fascinating to hear how a similar approach seems to yield extraordinary benefits in this entirely unrelated area of female health. Obviously, female infertility and pregnancy are unrelated to heart health, but the extraordinary benefits witnessed by Dr. Fox in this area suggest that some fundamental lessons in human physiology can be learned. The results are so incredible that we are all sure to hear more about this approach as experience grows.

So I tracked Dr. Fox down in his busy Jacksonville, Florida practice to fill us in on some details.

WD: Dr. Fox, could you tell us something about yourself and what led you to use carbohydrate restriction in your female patients?

MF: I have been in practice as a reproductive endocrinologist for 15 years. During that time, I have seen our specialty move from a broad based practice of reproductive endocrinology to a narrow IVF [in vitro fertilization] focus, with patients being pushed through IVF in a cookie-cutter fashion without any emphasis on non-medical therapy.

Our focus has been to remain as a broad practice where we individualize care and attempt in every case to achieve pregnancy short of IVF. Five years ago, this continued quest for better care led us into the insulin resistance, low-carbohydrate metabolic world that has transformed our practice, although our practice offers all aspects of reproductive endocrinology including sub-specialized minimally invasive surgery, and all available infertility options.

WD: I have been intrigued by your comments about improved fertility with the low-carb diet. Could you elaborate on this?

MF: Yes, five years ago, as more information regarding Polycystic Ovarian Disease or Syndrome (PCOD/S) and its relationship to insulin resistance (high insulin levels) was emerging, we had a simple realization. As we've known for some time, insulin stimulates excess male hormone levels in the ovary, which disrupts ovulation and fertility. Then our job was to lower or virtually eliminate high insulin levels. Again, in simple fashion, we looked at physiology and realized that insulin is released only in response to dietary carbohydrates. Thus, elimination of carbohydrates should resolve the problem. This, in fact, is the effect that we have seen.

In our previous approaches to PCOD, we utilized oral ovulation medicines generating pregnancy rates in the 40% range overall. Now, with the nutritional approach, for those patients that follow our recommendations, our pregnancy rates are over 90%! This has dramatically reduced the need for in vitro fertilization in these patients.

To extend this idea further, we first started with relative low-carbohydrate diets, such as the South Beach diet, but quickly realized this didn't produce a metabolic effect. Over time, it has borne out that only the very low-carbohydrate diet (VLCD) approach produces significant metabolic change. Our impression then was that the current U.S. nutritional exposure probably increases insulin levels and that this has a detrimental effect on fertility.

To counter this effect, we now recommend the VLCD to all fertility patients and their spouses. The pregnancy rates do seem much better overall, as well as seeing a reduction in miscarriage rates. For the first time at our national meeting last year, there were three articles that showed improved pregnancy rates in patients without PCOD or insulin resistance in IVF when Glucophage was used. This drug decreases insulin. This supports the idea that our entire population is subjected to fertility-reducing high-carbohydrate diet.

WD: Do you see any other changes in these patients on the diet?

MF: Yes. All metabolic parameters, as well as many common complaints, improve. Cholesterol and triglyceride levels improve, while "good" HDL cholesterol levels increase. Weight drops at a pace of 12 lbs per month very steadily and we have many many patients who have experienced 50lb wt loss. Blood pressure decreases steadily in these patients and we are often able to get them off of cholesterol and blood pressure medicines. Common symptoms such as anxiety, sleep disturbances, decreased energy, migraine headaches and depression all dramatically improve. Again we can often get patients off depression and migraine suppression medications. So this approach helps in a multitude of areas.
