Green coffee bean extract in AGF Factor I

Track Your Plaque's new and proprietary formulation, AGF Factor I, is designed to to support a program to achieve low levels of endogenous glycation.

Endogenous glycation, discussed at length in a recent Track Your Plaque Special Report, makes LDL particles (especially small LDL particles) more prone to oxidation and thereby more atherogenic, i.e., more likely to contribute to atherosclerotic plaque. Endogenous glycation also exerts unhealthy effects on long-lived proteins in the body, such as the proteins in the lenses of your eyes (cataracts), the lining of arteries (hypertension), and the cartilage cells of joints (brittle cartilage and arthritis).

Endogenous glycation is reduced by slashing carbohydrates in the diet, especially the most offensive carbohydrates of all, the amylopectin A of wheat, sucrose, high-fructose corn syrup and other fructose sources. Endogenous glycation can also be blocked by using blockers of the glycation reaction, such as benfotiamine (lipid-soluble thiamine), pyridoxal-5'-phosphate (a form of vitamin B6 with greater glycation blocking effect), and chlorogenic acid from green coffee beans, all components of AGF Factor I, which also contains Portulaca oleracea (Portusana), or purslane, for reduction of glucose.

Green coffee bean extract, and thereby chlorogenic acid, is receiving increased attention, most recently due to a study demonstrating substantial weight loss with 750-1050 mg green coffee bean extract, providing approximately 325-500 mg chlorogenic acid per day. Participants lost 15.4 pounds over 8 weeks at the higher dose (500 mg chlorogenic acid per day), while participants lost 8.8 pounds over 8 weeks at the lower dose (325 mg chlorogenic acid per day).

AGF Factor I was not formulated for weight loss but, taken twice or three times per day, does indeed mimic the dose of chlorogenic acid from green coffee bean extract used in the weight loss study. If you wish to take advantage of this application of chlorogenic acid/green coffee bean extract, while also maximizing protection from endogenous glycation, our AGF Factor I is one excellent choice to do so.

Lessons learned from the 2012 Low-carb Cruise

I just returned from Jimmy Moore's Low-carb Cruise, a 7-day excursion to Jamaica, Grand Cayman Island, and Cozumel aboard the Carnival Magic. During our 7 wonderful days, a number of authors and experts spoke, each offering their unique perspective on the low-carb world. The focus was the science, experience, and practical application of low-carbohydrate diets.

The event kicked off with a roast by Tom Naughton of Fat Head fame, who entertained with his insightful low-carb humor and predictions of my demise at the hands of Monsanto!

Among the most important lessons provided:

Dr. Andreas Eenfeldt of the Diet Doctor blog discussed how Sweden is leading the world as the nation with the most vigorous low-carbohydrate following, witnessing incredible weight loss and reversal of carbohydrate-related diseases way ahead of the U.S. experience. I spent several hours with Dr. Eenfeldt who, besides being an engaging speaker, is a new father and an all-around gentleman. At 6 ft, 7 inches, he also towered high above all of us.

Dr. Eric Westman of Duke University and author of The New Atkins for a New You, debunked low-carbohydrate myths, such as "low-carb diets are high-protein diets that make your kidneys explode."

Dr. John Briffa, creator of the popular blog, Dr. John Briffa: A Good Look at Good Health, and author of the wonderfully straightforward primer to low-carbohydrate eating, Escape the Diet Trap, stressed the importance of never allowing hunger to rule behavior. Dr. Briffa's serious writing tone conceals an incredible charm and wit that took me by surprise, having spent several thoroughly engaging hours over breakfast, lunch, and dinner with him over the week.

Fred Hahn, exercise expert, founder of Serious Strength and author of Slow Burn Fitness Revolution and Strong Kids, Healthy Kids, debunked a number of trendy exercise methods, boiling many of the purported benefits of exercise down to that of increased strength.

Dr. Chris Masterjohn of The Daily Lipid and supporter of the Weston A. Price Foundation program, provided a comprehensive overview of the data that fails to link saturated fat with heart disease. He also helped me understand the analytical techniques used in studies of advanced glycation end-products.

Denise Minger, brilliant young usurper of China Study dogma and blogger at Raw Foods SOS, proved an engaging speaker and a truly real person (since some critics of her analyses have actually questioned whether there was even such a person!). She also proved every bit as likable as she seems in her captivating blog discussions.

Dr. Jeff Volek, prolific researcher from University of Connecticut, author of over 200 studies validating low-carbohydrate diet effects, and author of the recently released book with Dr. Stephen Phinney, The Art and Science of Low Carbohydrate Living, debunked myths behind carbohydrate dependence and "loading" by athletes. He also talked about how assessing blood ketones may be the gold standard method to ensure low-grade ketosis on a long-term low-carb effort.

Over a bottle of wine, Jimmy Moore and I reminisced over how his modest start with no experience in blogging or media has now ballooned to an audience of over 100,000 readers/viewers.

All in all, Jimmy's Low-carb Cruise experience was worth every minute, with many wonderful lessons and memories!

Chili Sesame Crackers

Looking for something hot and crunchy?

These chili sesame crackers are perfect for dipping into hummus or salsa. As written, the recipe yields a moderately spicy cracker that you can modify readily by increasing or decreasing quantities of cayenne pepper and Tabasco sauce.

This recipe uses sesame seeds as the "flour." Either brown sesame seeds or the lighter version work, though the lighter seeds yield a slightly less bitter flavor with the spices.

For ease of baking, a shallow baking pan measuring 11 x 17 inches works best, as it allows the batter to fill the pan and spread to a cracker thickness. With a smaller pan, you may have to bake in two batches.

Makes approximately 30 chips

2 cups raw sesame seeds
1 cup shredded Parmesan cheese
2 tablespoons extra-virgin olive oil
1 tablespoon chili powder
½ teaspoon cayenne pepper
2 teaspoons onion powder
1 teaspoon garlic powder
1 teaspoon dry mustard
1 teaspoon sea salt
1 teaspoon Tabasco sauce
1¼ cups water

Preheat oven to 350º F.

In food chopper or food processor, grind 1¼ cups sesame seeds to fine meal. Remove and place in large bowl.

Place shredded Parmesan cheese in food chopper or food processor and pulse briefly until reduced to granular consistency. Add to sesame seed meal and mix. Stir in olive oil.

Add remaining (unground) sesame seeds, chili powder, cayenne pepper, onion and garlic powder, mustard, sea salt and mix thoroughly. Add Tabasco sauce and water and mix. Add additional water, if necessary, one tablespoon at a time, to obtain a consistency similar to pancake batter.

Pour mixture into baking pan and smooth to fill pan and obtain a thickness of a cracker. If too thick, remove some batter and re-smooth. Optionally, roll a clean cylindrical glass or bottle over top to smooth and yield a consistent thickness.

Bake for 30 minutes or until edges browned and center firm. If a dry, extra crunchy cracker is designed, bake an additional 10-15 minutes at 250 degrees F.

Remove and allow to cool. Cut with pizza cutter to desired size.

Opiate of the masses

Although it is a central premise of the whole Wheat Belly argument and the starting strategy in the New Track Your Plaque Diet, I fear that some people haven't fully gotten the message:

Modern wheat is an opiate.

And, of course, I don't mean that wheat is an opiate in the sense that you like it so much that you feel you are addicted. Wheat is truly addictive.

Wheat is addictive in the sense that it comes to dominate thoughts and behaviors. Wheat is addictive in the sense that, if you don't have any for several hours, you start to get nervous, foggy, tremulous, and start desperately seeking out another "hit" of crackers, bagels, or bread, even if it's the few stale 3-month old crackers at the bottom of the box. Wheat is addictive in the sense that there is a distinct withdrawal syndrome characterized by overwhelming fatigue, mental "fog," inability to exercise, even depression that lasts several days, occasionally several weeks. Wheat is addictive in the sense that the withdrawal process can be provoked by administering an opiate-blocking drug such as naloxone or naltrexone.

But the "high" of wheat is not like the high of heroine, morphine, or Oxycontin. This opiate, while it binds to the opiate receptors of the brain, doesn't make us high. It makes us hungry.

This is the effect exerted by gliadin, the protein in wheat that was inadvertently altered by geneticists in the 1970s during efforts to increase yield. Just a few shifts in amino acids and gliadin in modern high-yield, semi-dwarf wheat became a potent appetite stimulant.

Wheat stimulates appetite. Wheat stimulates calorie consumption: 440 more calories per day, 365 days per year, for every man, woman, and child. (440 calories per person per day is the average.) We experience this, sense the weight gain that is coming and we push our plate away, settle for smaller portions, increase exercise more and more . . . yet continue to gain, and gain, and gain. Ask your friends and neighbors who try to include more "healthy whole grains" in their diet. They exercise, eat a "well-balanced diet" . . . yet gained 10, 20, 30, 70 pounds over the past several years. Accuse your friends of drinking too much Coca Cola by the liter bottle, or being gluttonous at the all-you-can-eat buffet and you will likely receive a black eye. Many of these people are actually trying quite hard to control impulse, appetite, portion control, and weight, but are losing the battle with this appetite-stimulating opiate in wheat.

Ignorance of the gliadin effect of wheat is responsible for the idiocy that emits from the mouths of gastroenterologists like Dr. Peter Green of Columbia University who declares:

"We tell people we don't think a gluten-free diet is a very healthy diet . . . Gluten-free substitutes for food with gluten have added fat and sugar. Celiac patients often gain weight and their cholesterol levels go up. The bulk of the world is eating wheat. The bulk of people who are eating this are doing perfectly well unless they have celiac disease."

In the simple minded thinking of the gastroenterology and celiac world, if you don't have celiac disease, you should eat all the wheat you want . . . and never mind about the appetite-stimulating effects of gliadin, not to mention the intestinal disruption and leakiness generated by wheat lectins, or the high blood sugars and insulin of the amylopectin A of wheat, or the new allergies being generated by the new alpha amylases of modern wheat.

Jelly beans and ice cream

What if I said: "Eliminate all wheat from your diet and replace it with all the jelly beans and ice cream you want."

That would be stupid, wouldn't it? Eliminate one rotten thing in diet--modern high-yield, semi-dwarf wheat products that stimulate appetite (via gliadin), send blood sugar through the roof (via amylopectin A), and disrupt the normal intestinal barriers to foreign substances (via the lectin, wheat germ agglutinin)--and replace it with something else that has its own set of problems, in this case sugary foods. How about a few other stupid replacements: Replace your drunken, foul-mouthed binges with wife beating? Replace cigarette smoking with excessive bourbon?

Sugary carbohydrate-rich foods like jelly beans and ice cream are not good for us because:

1) High blood sugar causes endogenous glycation, i.e, glucose modification of long-lived proteins in the body. Glycate the proteins in the lenses of your eyes, you get cataracts. Glycate cartilage proteins in the cartilage of your hips and knees, you get brittle cartilage that erodes and causes arthritis. Glycate structural proteins in your arteries and you get hypertension (stiff arteries) and atherosclerosis. Small LDL particles--the #1 cause of heart disease in the U.S. today--are both triggered by blood sugar rises and are 8-fold more prone to glycation (and thereby oxidation).

2) High blood sugar is inevitably accompanied by high blood insulin. Repetitive surges in insulin lead to <em>insulin resistance</em>, i.e., muscles, liver, and fat cells unresponsive to insulin. This forces your poor tired pancreas to produce even more insulin, which causes even more insulin resistance, and round and round in a vicious cycle. This leads to visceral fat accumulation (Jelly Bean Belly!), which is highly inflammatory, further worsening insulin resistance via various inflammatory mediators like tumor necrosis factor.

3) Sugary foods, i.e., sucrose- or high-fructose corn syrup-sweetened, are sources of fructose, a truly very, very bad sugar that is metabolized via a completely separate pathway from glucose. Fructose is 10-fold more likely to induce glycation of proteins than glucose. It also provokes a (delayed) rise in insulin resistance, accumulation of triglycerides, marked increase in formation of small LDL particles, and delayed postprandial (after-eating) clearance of the lipoprotein byproducts of meals, all of which leads to diabetes, hypertension, and atherosclerosis.

I think we can all agree that replacing wheat with jelly beans and ice cream is not a good solution. And, no, we shouldn't have drunken binges, wife beating, smoking or bourbon to excess. So why does the "gluten-free" community advocate replacing wheat with products made with:

rice starch, tapioca starch, potato starch, and cornstarch?

These powdered starches are among the few foods that increase blood sugar (and thereby provoke glycation and insulin) higher than even the amylopectin A of wheat! For instance, two slices of whole wheat bread typically increase blood sugar in a slender, non-diabetic person to around 170 mg/dl. Two slices of gluten-free, multigrain bread will increase blood sugar typically to 180-190 mg/dl.

The fatal flaw in thinking surrounding gluten-free junk carbohydrates is this: If a food lacks some undesirable ingredient, then it must be good. This is the same fatally flawed thinking that led people to believe, for instance, that Snack Well low-fat cookies were healthy: because they lacked fat. Or processed foods made with hydrogenated oils were healthy because they lacked saturated fat.

So gluten-free foods made with junk carbohydrates are good because they lack gluten? No. Gluten-free foods made with rice starch, tapioca starch, potato starch, and cornstarch are destructive foods that NOBODY should be eating.

This is why the recipes for muffins, cupcakes, cookies, etc. in this blog, the Track Your Plaque website, and the Track Your Plaque Cookbook are wheat- and gluten-free and free of gluten-free junk carbohydrates. And put that bottle of Jim Beam down!

Diet by LDL

Conventional notions of heart healthy diets, such as that advocated by the American Heart Association, are largely based on observations of total and LDL cholesterol.

So, cut the saturated fat in the diet, cut the overall fat content, and replace them with polyunsaturated oils like safflower, corn, and vegetable oils and increase consumption of whole grains and total and LDL cholesterol show a modest downturn. Thus, diets like the American Heart Association Total Lifestyle Change approach advocate limiting total fat to no more 25 to 35% of calories and saturated fat to no more than 7% of calories.

Orange Cream Cookies

If you loved Creamsicles as a kid, you'll love these Orange Cream Cookies. (Sorry, no photo: We ate them up before I realized we hadn't taken the photo. And, worse, we did it twice!)

Ingredients:
2 cups almond meal
2 tablespoons coconut flour
1 teaspoon baking soda
½ teaspoon sea salt
¼ cup golden raisins
½ cup chopped pecans
Sweetener equivalent to 1 cup sugar
2 tablespoons finely-grated orange rind
1 large egg
2 tablespoons coconut oil, melted
½ cup whipping cream (or coconut milk)
1 tablespoon vanilla extract

Preheat oven to 350º F.

Combine almond meal, coconut flour, baking soda, salt, raisins, pecans, sweetener and orange zest in bowl and mix.

In separate bowl, whisk egg, then add coconut oil, whipping cream, vanilla extract and mix together. Pour wet mix into dry and blend by hand thoroughly.

Spoon onto parchment paper-lined baking pan (or oiled pan) and flatten with spoon to ½-¾ inch thickness. Bake for 20-25 minutes or until toothpick withdraws dry.

Why are heart attacks still happening?

I'm a cardiologist. I see patients with heart disease in the form of coronary artery disease every day.

These are people who have undergone bypass surgery, received one or more stents or undergone other forms of angioplasty, have survived heart attacks or sudden cardiac death, or have high heart scan scores. In short, I see patients every day who are at high-risk for heart attack and death from heart disease.

But I see virtually no heart attacks. And nobody is dying from heart disease. (I'm referring to the people who follow the strategies I advocate, not the guy who thinks that smoking a pack of cigarettes a day is still okay, or the woman who thinks the diet is unnecessary because she's slender.)

Two high-profile deaths from heart attacks occurred this week:

Davy Jones--The iconic singer from the 1960s pop group, the Monkees, suffered sudden cardiac death after a large heart attack, just hours after experiencing chest pain.

Andrew Breitbart--The conservative blogger and controversy-generating media personality suffered what was believed to be sudden cardiac death while walking.

It's a darn shame and it shouldn't happen. The tools to identify the potential for heart attack are available, inexpensive, and simple. The strategies to reduce, even eliminate, risk are likewise available, inexpensive, and cultivate overall health.

The followers of the Track Your Plaque program who

1) get a heart scan that yields a coronary calcium score (for long-term tracking purposes)
2) identify the causes such as small LDL particles, lipoprotein(a), vitamin D deficiency, and thyroid dysfunction
3) correct the causes

enjoy virtual elimination of risk.

My letter to the Wall Street Journal: It's NOT just about gluten

The Wall Street Journal carried this report of a new proposed classification of the various forms of gluten sensitivity: New Guide to Who Really Shouldn't Eat Gluten

This represents progress. Progress in understanding of wheat-related illnesses, as well as progress in spreading the word that there is a lot more to wheat-intolerance than celiac disease. But, as I mention in the letter, it falls desperately short on several crucial issues.

Ms. Beck--

Thank you for writing the wonderful article on gluten sensitivity.

I'd like to bring several issues to your attention, as they are often neglected
in discussions of "gluten sensitivity":

1) The gliadin protein of wheat has been modified by geneticists through their
work to increase yield. This work, performed mostly in the 1970s, yielded a form
of gliadin that is several amino acids different, but increased the
appetite-stimulating properties of wheat. Modern wheat, a high-yield, semi-dwarf
strain (not the 4 1/2-foot tall "amber waves of grain" everyone thinks of) is
now, in effect, an appetite-stimulant that increases calorie intake 400 calories
per day. This form of gliadin is also the likely explanation for the surge in
behavioral struggles in children with autism and ADHD.
2) The amylopectin A of wheat is the underlying explanation for why two slices
of whole wheat bread raise blood sugar higher than 6 teaspoons of table sugar or
many candy bars. It is unique and highly digestible by the enzyme amylase.
Incredibly, the high glycemic index of whole wheat is simply ignored, despite
being listed at the top of all tables of glycemic index.
3) The lectins of wheat may underlie the increase in multiple autoimmune and
inflammatory diseases in Americans, especially rheumatoid arthritis and
inflammatory bowel diseases (ulcerative colitis, Crohn's).

In other words, if someone is not gluten-sensitive, they may still remain
sensitive to the many non-gluten aspects of modern high-yield semi-dwarf wheat,
such as appetite-stimulation and mental "fog," joint pains in the hands, leg
edema, or the many rashes and skin disorders. This represents one of the most
important examples of the widespread unintended effects of modern agricultural
genetics and agribusiness.

Why ATP-3 is B--- S---

Why ATP-3 is B--- S---

A Heart Scan Blog reader posted the link to this very excellent presentation by Dr. David Diamond, a neuroscientist at the University of South Florida.

ATP-3, or Adult Treatment Panel-3, is the set of cholesterol treatment guidelines as established by the National Cholesterol Education Panel, the guidelines used by practicing physicians nationwide. They are also the metric by which the "quality" of care is being judged by agencies like Medicare, health insurers, and other parties interested in policing healthcare. Dr. Diamond ably recounts how we ended up in this mess, the conflagration of "cut your fat, reduce cholesterol, and take a statin drug."

I was very impressed that, in his closing comments, he briefly discusses the pivotal role of glycation in heart disease causation. You will see in coming conversations how important an understanding of glycation is to create a healthy diet and lifestyle.

    Hi Dr. Davis.
    I’m actually both pleased and troubled with the link to Dr. Diamond’s presentation that you’ve provided.

    On the “pleased” side, Dr. Diamond’s analysis is:
    •  An excellent/very well done presentation
    •  Fact based (e.g. cites numerous studies, documented references, named experts, etc.)
    •  Spans the test of time (e.g. references from the 1800’s thru the present day)
    •  Ferrets out the major drivers of our present-day obesity epidemic & debunks other commonly held beliefs
    •  Synchs with some of the Track Your Plaque (TYP) tenants (e.g. TYP guidance on triglycerides, diet, sugars, etc.)
    •  â€œFlags” potential issues like conflict of interest which might have a tendency to creep into the science on occasion (e.g. the Keys report, the errant conclusions resulting from the NCEP report and supporting studies, etc.)

    On the “troubled” side, Dr. Diamond’s analysis seems to:
    •  Fly in the face of some of the foundational tenants of TYP
    •  His analysis/conclusions, and that of other experts he cites, is that cholesterol of any kind is NOT correlated with Coronary Heart Disease (CHD) – at least as a root cause of heart disease (see Myth #2 and Dr. Diamond’s related analysis)
    •  That LDL cholesterol – and although not stated by Dr. Diamond I’m inferring – the “sticky kind”, i.e. the small particles that actually adhere to artery walls (not the fluffy LDL particles that bounce away), are actually good!! On his “Final Issues 2” slide, and later in his related pictorial slides (entitled “What Causes Coronary Heart Disease?”), he makes reference to [LDL] cholesterol as a “Misunderstood Hero”?
    •  That small, sticky LDL particles actually help the body recover from the damage created by the real culprits… sugars that work in concert with certain bacterias to create micro-tears in our artery walls
    •  That small, sticky LDL actually results in the belt-and-suspenders, Rube-Goldberg “spackle” [which again I infer from Dr. Diamond’s presentation ultimately becomes plaque], that fixes (admittedly in a suboptimal and too-late manner) the damage already done by the artery-tearing, sugar/bacteria combo.  Plaque caused by LDL is actually the ‘finger in the dike’, last ditch effort, to fix the artery tears!  Kind of the last line of defense. [see slides on page 53 and Dr. Diamond’s related YouTube discussion.]

    As a result, just curious about your thoughts on Dr. Diamond’s hypotheses.  
    1.  Am I getting Dr. Diamond’s message(s) right?
    2.  If yes, do you concur with – or tend toward – the theory(-ies) supported by Dr. Diamond and other cited experts about the role of cholesterol in CHD?  I gather from your blog post that you sympathize with his glycation theory(-ies), but how about the rest?
    3.  If yes again, does that change some of the TYP direction?  For example, a significant part of the TYP approach is to reduce, as much as possible, small LDL particles. If LDL – and thus the resulting plaque – is indeed a suboptimal last line of defense, does reduction of LDL particles lead to a sub-optimization of the body’s last-ditch defense/“back-up plan” to deal with arterial microtears?
    4.  Also, knowing that plaque/“spackle” is admittedly a suboptimal last ditch effort, what consequence does reversing plaque ultimately have given that the real damage – the tears in the artery walls (the seemingly real CHD culprits) – has already occurred. Are we pulling the finger out of the dike… without addressing the real root cause of the problem?  â€¦and if yes, what’s the back-up plan to the body’s back-up plan? If we reduce LDL and plaque, and the arterial damage is already done due to years and years of sugar abuse, what plugs the dike then?  I’m not talking about the preventive approaches of avoiding glycation in the first place… obviously that seems to be the real, preventive answer. I’m referring to those of us – for whom preventative measures are too late because the microtears are already there – who might be already living with the consequences of years of potentially errant diet/health guidance (by Keys, NCEP, etc.) and thus “spackle” in our arteries?  If the "spackle" is removed, does the dike start leaking again?

    Although I thought I was “on the path to CHD righteousness”, I’m now confused again as a result of Dr. Diamond’s insights. Thanks for any clarifications Dr. Davis!

    Dr. Davis,
    I'm also anxious to hear what you think of the "hero" role of LDL in plaque.  I'm hoping he didn't go too far off the reservation on this point because the entire hour long presentation was so well done (comprehensive, well-explained, and credentialed) that it will be a powerful aid in spreading the word on both carbohydrates and how messed up the typical GP is with cholesterol treatment (not their fault - but the ATP-III as you say).  It was the tipping point for me.  I'm going off Lipitor now, which I"ve been on for years and will look into your TYP program to ensure I'm doing the right thing.

  • Dr. William Davis

    8/21/2011 3:27:30 PM |

    HI, Joe--

    This "hero" thing, to my knowledge, is extrapolation and supposition. It is an interesting notion. I, too, was impressed with his presentation, but I think that the "hero" thing paints LDL as an entirely innocent player and I don't believe it is. We have only to look at people with heterozygous familial hypercholesterolemia who can have heart attacks in their 30s with pure large LDL to know that there is more to LDL's behavior than a protective function.

  • Dr. William Davis

    8/21/2011 3:31:20 PM |

    Hi, G--

    By providing the link to Dr. Diamond's wonderful talk, I didn't mean to suggest that everything he says should be taken as gospel.

    Virtually everything he said up until the "spackle" I do agree with. The spackle argument is pure supposition. It makes sense, but only to a degree and ignores the quantitative (e.g., heterozygous familial hypercholesterolemia) and qualitative (small, oxidation- and glycation-prone LDL particles with unique conformations that differ from larger LDL) differences in LDL particles.

    Nonetheless, Dr. Diamond's recounting of how this mess was created was enlightening and well-presented and I still enjoyed it.

    8/21/2011 5:53:07 PM |

    Dr. Davis,

    I watched Dr. Diamond's presentation in its entirety.  I agree that he's done some great investigative medicine, especially looking into long-established research on carbohydrate intake, and, more recently, digging into questions of research funding and conflicts of interest.

    His presentation leaves me with a major question about the role of cholesterol.  Diamond claims that high cholesterol levels are not harmful, so long as they are below 300 mg/dL, and that cholesterol has a helpful role.  It is used by arteries to repair themselves after the arterial lining is torn, infected by bacteria, or otherwise damaged.  This is why, he says, we find cholesterol in atherosclerotic plaques, together with white blood cells and dead bacteria.  Yet, we know from your reports and others that an elevated LDL particle number *is* correlated with coronary events.

    What's going on here?  Is cholesterol itself harmful, or is high particle number just another symptom of high carbohydrate intake, which causes glycation and loss of elasticity in the arterial walls, leading to damage?

  • Brian

    8/21/2011 6:03:20 PM |

    I just read the other comments, so the above question has been answered.  Thanks for all the info!

  • Dr. William Davis

    8/23/2011 11:57:16 AM |

    Hi Brian--
    While I truly enjoyed Dr. Diamond's presentation, I think this particular path leads us down a dead end.

    I don't think cholesterol per se is harmful; I believe that the particles that contain, among many other things, cholesterol can be harmful, especially small, oxidation-prone, glycation-prone LDL particles. I believe it would be an incredible stretch to say that small LDL particles are somehow protective.

    I have inherited cholesterol and just learned from my health store guy that all the grains I have been eating are likely responsible for the high numbers of my small LDL(527) particles.  I thought oatmeal and other whole grains would squeege-mop the bad guys out of my system.  This news is also likely why I haven't  lost any weight (I eat lots of veggies and apples, fibrous fruits and protein.)  I do not use processed foods at all.  I walk a mile to work each day and I am still 10-20 # overweight (and yes it is right in my middle.)  My health guy is the one who directed me to this blog.  Any other information is most welcome.  I am trying to figure out what to fix everyday (supper/dinner) is the hardest.
