Thank you, Dr. Eades


Thanks to some readers of The Heart Scan Blog, I've become acquainted with Dr. Michael Eades' wonderful blog, Health and Nutrition by Dr. Michael R. Eades, MD.

Dr. Eades is co-author (with his wife, Mary Dan Eades, MD) of Protein Power

In one of his conversations, I stumbled on this exchange between Dr. Eades and one of his readers:



Reader: Regarding EBT scans, I looked up the topic on Google and read an informative 5-page article: EBT (Ultrafast CT) Scans - Godsend, or Scam? Dr. Fogoros says that false positives (where the EBT shows the presence of calcium, but the patient has little coronary artery blockage) occur about 50 percent of the time. The next step, if the EBT is positive, is to do a heart catherterization to find out whether there actually is coronary artery blockage. So the odds are that I’d have to worry!

Dr. Michael Eades: The info you got from Google is one of the reasons one shouldn’t get medical information online. As far as I’m concerned the EBT is the BEST way to determine the presence of plaque. If you have a positive calcium score, you have plaque, and there’s an end on’t (as Samuel Johnson would say). Now you may have a low calcium score for your age or you may have a calcium score that doesn’t change, which means you have stable plaque, but if you have a positive calcium score, you have some amount of plaque in your coronary arteries.

And whoever says that the next step to take if you receive a positive calcium score is a coronary artery cath is a real moron. That’s probably the last thing you would want to do if you are asymptomatic. All the cath procedure does is shows whether or not you have a blockage - you can have huge amounts of plaque (which are a disaster waiting to happen) and have a normal cardiac cath.

If you want to get a little more information on the validity of EBT than what you find on Google, take a look at Dr. Davis’ blog or get a copy of his book: Track Your Plaque. I’m not crazy about all of Dr. Davis’ dietary recommendations because he comes to diet from a different perspective than I, but the EBT info in his book is terrific.

Cheers–


Dr. Eades "gets" it. He understands that quantification of coronary plaque is a tool for prevention, not something to be subverted into the service of procedures for the financial benefit of my colleagues.

And I think that he is absolutely correct on the diet discussed in Track Your Plaque--it's due for a revision. I wrote the book in 2003, while we were still locked into the low-fat mindset. Much has changed.

Since then, our enormous experience in metabolic manipulation and lipoprotein analysis has shown that there is a far better way to correct the causes of coronary plaque and seizing hold of heart scan scores. In particular, the explosion of small LDL has prompted major changes in the diet, specifically removal of wheat and cornstarch, the foods that trigger small LDL particles.

(I am still in the midst of negotiations for release of a bigger and better Track Your Plaque II. In the meantime, Track Your Plaque Members can refer to the New Track Your Plaque Diet, Parts I, II, and III.)

    People like you and Dr. Eades have my complete respect precisely because you're not only willing but eager to adjust your advice in accordance with your understanding of the latest and best science.  Like you, Dr. Eades is constantly pointing out where he's adjusted his recommendations, whether from an earlier book or even just an earlier post.

    Contrast that behavior with the latest diet study where Bray et al attempted to pass off a diet including daily rations of bagels, pasta, and bananas as "low carb."  How sad, how grotesque authority figures are when they cling to a pretense that there is nothing for them to learn!  And they led Harvard University, the New England Journal of Medicine and most of the "health" writers in the nation right into the briar patch!

    Another thing to consider adding to the new book is something about periodontal/gingival disease which is a constant source of inflammation in the body leading to elevated CRPs.

    Dr. D., the Dr's. Eades have shaped my thinking about diet more than any other source, specifically their emphasis on carbohydrates and the  role of insulin in  disease.  I am thrilled that you admire each other, thus confirming my intuition about the worth of each of your approaches.  I also judge you and the the Eades to be of the highest caliber as debunkers. I may never meet any of you, but you are the team I regard as my primary health advisers, along with Dr. John Cannell.  May you all thrive, and may many others learn from you and thrive as well.  Though I found the Eades in the book store many years ago, I am so grateful that the Internet now provides us all with such a valuable tool to work for our own well being.  The more successful we all are  in this enterprise, the sooner our health care becomes truly our own, and the better it will be.  Onward!

    seems to me that if you are far away from TYP goals of 60/60/60 that you should through diet/nutrition supplements just work towards those goals.  Why not just get frequent NMR tests and avoid any level of radiation?

    I was born and brought up on newsgroups, used various forums and came late to the blogosphere. To you and the estimable Michael Eades I'd add Mark Sissons and Hyperlipid as must-reads. You all come at the same conclusions from different perspectives, and keep up with current work.

    Hi Dr. Davis.  
    Another blog you may want to check out is "whole health source."
    His latest post is about a recent study examining the effects of Vitamin K on heart disease.  Here's the link:

Postprandial pile-up with fructose

Postprandial pile-up with fructose

Heart disease is likely caused in the after-eating, postprandial period. That's why the practice of grazing, eating many small meals throughout the day, can potentially increase heart disease risk. Eating often can lead to the phenomenon I call triglyceride and chylomicron "stacking," or the piling up of postprandial breakdown products in the blood stream.

Different fatty acid fractions generate different postprandial patterns. But so do different sugars. Fructose, in particular, is an especially potent agent that magnifies the postprandial patterns. (See Goodbye, fructose.)

Take a look at the graphs from the exhaustive University of California study by Stanhope et al, 2009:



From Stanhope KL et al, J Clin Invest 2009. Click on image to make larger.

The left graphs show the triglyceride effects of adding glucose-sweetened drinks (not sucrose) to the study participants' diets. The right graphs show the triglyceride effects of adding fructose-sweetened drinks.

Note that fructose causes enormous "stacking" of triglycerides, meaning that postprandial chylomicrons and VLDL particles are accumulating. (This study also showed a 4-fold greater increase in abdominal fat and 45% increase in small LDL particles with fructose.)

It means that low-fat salad dressings, sodas, ketchup, spaghetti sauce, and all the other foods made with high-fructose corn syrup not only make you fat, but also magnifies the severity of postprandial lipoprotein stacking, a phenomenon that leads to more atherosclerotic plaque.

    Dr. Davis,

    Given this information. If someone has a good BMI and good overall diet without grains, how much fruit should they limit themselves to in a day. Should they only eat this fruit with a meal and not eat it alone between meals?

    Is Grazing on protein and vegetables also bad?

    Wow. I guess fructose of any source would be bad, not just HFCS but eating an apple as well? It's hard to rationalize why something that is found in nature, is a whole food, and appeals to our sense of taste, would be bad for us. Maybe the fact that the fructose in the the study was in liquid form, versus being held up in some fiber, had something to do with the results but this isn't the first time that I have read that fruit is bad for you.

  • Dr. William Davis

    Keep in mind that the design of studies like this are often meant to yield exagerrated effects for the purposes of clean observations. It does not necessarily mean that every time you eat, you get similar postprandial phenomena.

    Nonetheless, I believe there are important lessons from such studies.

    This study suggests that a rice cracker or a potato (converted directly to gluclose) might be more healthful than a piece of fruit

    I've been able to adapt relatively easily to everything in your TYP program Dr. Davis, but this one seems to be the toughest for me.

    I don't think I can eat one meal a day.  I have always been blessed with a fast metabolism and need at least 3,000 (LC) calories even on a moderately active day, or I start to lose weight, which at 5' 9" 165# @ 8% BMI, I don't want to do, and probably shouldn't.

    3,000 calories is simply too much for me to eat in one meal.  Plus, it seems so counter-intuitive to good health, like maintaining a good energy/thermogenic/glucose/insulin/nitrogen balance throughout the day.  It just seems a perfect recipe for storing fat at the expense of lean mass, which is the complete opposite of paleolithic man's highly muscular, lean composition. I don't know, maybe just I wouldn't survive well back then...

    This is an excellent point- the reverse of intermittent fasting and variation in calorific consumption. Excess macronutirent calories, in the wrong form, at frequent intervals. No surprise there are adverse implications. OB

    Re fructose from fruit vs HFCS, I don't think that there's much comparison.

    There are benefits to eating fruit (antioxidants, fiber, vitamins).  There is no benefit to consuming HFCS.

    Choose your fruits carefully and eat in moderation...

    I doubt that eating fruit is the same as eating refined fructose.  Not all fruit is high in fructose, for instance.  Also, the fiber in the fruit slows absorption, and this may give time for the fructose to be fermented by bacteria in the gut, producing, for instance, acetic acid, which may be beneficial to fat deposition patterns. (This is just a personal theory of mine.)  

    Furthermore, fruit contains vitamins, minerals, antioxidants, and flavoniods, which can benefit glucose metabolism, prevent lipid oxidization, and dampen the tide of free radicals and advanced glycation end-products (AGEs) produced by glucose and fructose metabolism.

    Those concerned with the effects of fructose from fruit should focus on eating whole fruits only (no juice), and eat mostly berries (low in fructose, high in flavonoids).

    I think it would be wise to separate the valid concerns about refined fructose from fruit.  We could be as off-base about vilifying fruit as people were about eggs.

    Just because a food contains a substance that can is harmful when it's been refined from its source doesn't mean that it has the same effect when found in a whole food.  The digestion and metabolism of whole foods is far more complex than can be understood by studying a single factor.

    If it's something humans have eaten for millennia, and it's safe to say that fruit is, I think it's probably innocent until proven guilty.  Just don't eat refined stuff (including juice), and you'll be fine.

    I am now trying to eat a diet that is very low in carbohydrates, moderate in protein, and high in fats like butter, omega-3 eggs, and cream cheese.

    This kind of diet seems to prevent the blood glucose spikes and the very unpleasant tachycardia that I get from high-carb meals.

    And it is frequent small meals that best control my blood glucose and the tachycardia.

    Pmp--

    Eating once a day was not the intended message.

    This discussion is simply part of a larger discussion on the effects of various foods on postprandial patterns. We must all eat and preferably do so 3 times a day.

    Hey, not all  spaghetti sauce has added fructose. Those made with sugar and or fructose cost more, because they are cheating on the ingredients.

    And yes, sugar is (half) fructose.

    Dr. William Davis, do we have any studies that show 3 times a day is optimal? One could hardly do a double blind study on this.

    I ate 50 grams of grapefruit (with extra fiber), with my last meal of the day and it spiked my blood sugar from 120 to 170 in 1 hr and I think I felt the beta cell damage for several hours - fruit is worse than oatmeal WITH sugar! I am pre-diabetic. I am trying to give up all bad things, but I am starving and I have to eat. I have chewing problems, so this complicates things. I tried soymilk, but it seemed to destabilize me, which is not good - I'll try it with fiber next time. I am underweight now. I am in a real bad place. I can't eat fruit anymore and even veggies give me problems. I hope I can avoid scurvy. Does anyone know if vitamin C pills truly prevent scurvy?
