The world according to the Wheat Foods Council and the Whole Grains Council

23. April 2010 William Davis (26)

You might get a kick out of what the Wheat Foods Council and the Whole Grains Council recommend for a sample meal plan:

Breakfast: Whole grain raisin toast
Lunch: Sandwich on whole grain
Snack: Rye bread crackers
Dinner: Whole grain pasta with your favorite sauce

Breakfast: Whole grain waffles 
Lunch: Hamburger on whole grain bun
Snack: Graham crackers
Dinner: Whole grain homemade pizza on whole grain pita crust

Remember Morgon Spurlock's documentary movie, Super Size Me? (If you haven't already seen it, Super Size Me is viewable for free on Hulu.) Spurlock conducts a self-inflicted 30-day experiment of eating at McDonald's fast food restaurants every day. In short, the results on Spurlock's weight and health are disastrous. 

How about Wheat Belly: The Movie? We would chronicle our star through a 30-day course of meals served up by the Wheat Foods and Whole Grains Councils, all featuring wonderful wheat products in every meal. We could measure blood sugar, triglycerides, LDL, small LDL, weight, etc.


Any predictions?

Why bananas increase cholesterol

21. April 2010 William Davis (0)
Anything that increases postprandial (after-eating) blood sugar will increase the number of LDL particles in the blood.

An increase in LDL particles is an important factor in causing heart disease: The greater the number of LDL particles, the more opportunity they have to interact with the walls of arteries, contributing to atherosclerosis.

Carbohydrates increase small LDL, especially if postprandial sugar is increased. Here's another way carbohydrates increase LDL particles: The duration of time LDL particles hang around in the blood stream is doubled.

When blood sugar increases, such as after the 30 grams carbohydrates in a medium-sized banana, glycation of LDL particles occurs. This means that a gglucose (sugar) molecule reacts with a lysine residue in the apoprotein B of the LDL particle. This induces a change in conformation that makes it less readily recognized by the LDL receptor. Thus, the glycated LDL particle persists for a longer period of time in the blood stream.

LDL particles are therefore cleared less efficiently, numbers of LDL particles increase.

Plant-based or animal-based?

19. April 2010 William Davis (78)
The ideal diet for heart and overall health restricts carbohydrate intake. I say this because carbohydrates:

Make you fat--Carbohydrates increase visceral fat, in particular.
Increase triglycerides
Reduce HDL
Increase small LDL particles
Increase glycation of LDL
Increase blood pressure
Increase c-reactive protein

Reducing carbohydrates reverses all the above.

But here's a common mistake many people make when following a low-carbohydrate diet: Converting to a low-carb, high-animal product diet.

It accounts for a breakfast of a 3-egg omelette with cheese and butter, 4 strips of bacon, 2 sausages, cream in coffee. Low-carb? It certainly is. But it is a purely high-animal product, no-plant-based meal.

I believe a strong argument can be made that a low-carbohydrate but plant-based diet with animal products as the side dish is a better way to go.

Consider that:

1) Animal products have little to no fiber, while plant-based products like spinach, avocado, and walnuts and other raw nuts have substantial quantities.

2) Plant products are a source of polyphenols and flavonoids--This encompasses a large universe of nutrients, from epigallocatechins in tea, polymeric procyanidins from cocoa, to hydroxytyrosol from olives, and anthocyanins from red wine and eggplant. The inflow of these beneficial compounds needs to be frequent and generous, not piddly amounts taken infrequently.

3) Vitamin C--While it's easy to obtain, the fact that you and I need to obtain vitamin C from frequent ingestion of plant sources suggests that humans were meant to eat lots of plants. While it may require a few months of deficiency before your teeth fall out, imagine what low-grade deficiency can do over a long period.

4) Vitamin K1--Rich in green vegetables, vitamin K1 is virtually absent in animal products.

5) Tocotrienols--I've been watching the data on this fascinating family of powerful oil-soluble antioxidants unfold for 20 years. Tocotrienols come only from plants. (I recently had an extended conversation with the brilliant biochemist, Dr. Barrie Tan, who is incredibly knowledgeable about tocotrienols, having developed several methods of extraction from plants, including his discovery of the highly concentrated source, annatto. Be sure to watch for future conversations about tocotrienols.)

6) Meats and dairy yield a net acid load--While plant foods are net basic. At the very least, this yields risk for osteoporosis, since acids are ultimately buffered by basic calcium salts from the bones. Tissue and blood pH is a tightly regulated system; veering off just a teensy-weensy bit from the normal pH of 7.4 to an acidic pH of, say, 7.2, leads to . . . death. In short, pH control is very important. A net acid challenge from animal products is a lot like drinking carbonated soda, a huge acid challenge that leads to osteoporosis and other health issues.

Conversely, a pure plant-based diet has its own set of problems. Eating a pure plant-based diet can lead to deficiencies of vitamin B12, omega-3 fatty acids (no, linolenic acid from flaxseed will NOT cut it), vitamin K2, carnitine, and coenzyme Q10.

So, rather than a breakfast of 3-egg omelet with bacon, sausage, cream, and cheese, how about a handful of pecans, some blueberries, and a 2-egg omelet made with basil-olive oil pesto? Or a spinach salad with walnuts, feta cheese, and lots of olive oil?

Fat is not the demon

16. April 2010 William Davis (36)
So my patient, Dane, generously volunteered to be on the Dr. Oz show, as I discussed previously.

What we didn't know, nor did the producer who contacted us mention, that Dane would be counseled by low-fat guru Dr. Dean Ornish on a strict low-fat diet. The teaser introduction essentially tells the entire story.

Ironically, that is the exact opposite of the dietary program that I advocate. I rejected the 10% fat diet long ago after I became a type II diabetic, gained 30 lbs, and suffered miserable deterioration of my cholesterol values on this diet. I also witnessed similar results in many hundreds of people, all following a strict low-fat diet. In fact, elimination of wheat--whole, white, or otherwise--along with limitation or elimination of all other grains has been among the most powerful health strategies I have ever witnessed.

I now regret having subjected my patient to this theatrical misinformation. Dane is a smart cookie--That's probably why he was not allowed more than a "yes" or "no" during Dr. Oz's monologue, else Dane might have pitched in about some ideas that would have tripped Oz and Ornish up.

In their defense, if we took 100 Americans all following a typical 21st century diet of fast food, white bread buns, Coca Cola and other soft drinks, chips, barbecue sauce, and French fries, converting to a plant-based, high-carbohydrate, grain-rich diet is indeed an improvement. People will, at first, lose weight and enjoy an initial response. (The occasional person with the Apo E4 genetic pattern, heterozygote or homozygote, may even enjoy long-term benefits, a topic for another day.)

But the majority of people, in my experience, after an initial positive response to an Ornish-like low-fat, high-carbohydrate diet will either plateau (stay overweight, have low HDL, high triglycerides, plenty of small LDL, and high blood sugars) or deteriorate, much as I did.

Thankfully, Dane has been a good sport about this, understanding that this is essentially show business. I believe he understands that the information was all well-intended and, after all, we are all working towards the same goal: reduction of heart disease risk.

By the way, regardless of which diet you follow, it is, in my view, absurd to believe that diet alone will do it. What about vitamin D normalization, thyroid normalization (thyroid disease is incredibly common), omega-3 fatty acids from fish oil, identification of hidden sources of risk (something that is unlikely in Ornish, since small LDL particles skyrocket on a low-fat diet), postprandial glucoses, etc., all the pieces we focus on to gain control over coronary plaque? Eating green peppers and barley soup alone is not going to do it.

Near-fatal brush with nattokinase

14. April 2010 William Davis (0)
Here is precisely why I have spoken out against nattokinase: People may put faith in this "supplement" when there are virtually no data to support its use in such dangerous conditions as pulmonary embolism.

Pulmonary embolism occurs when a large volume of blood clots in the veins of the pelvis, abdomen, and into the legs. A clot breaks off and lodges in the pulmonary arteries of the lungs. This can be fatal within minutes to hours, the victim struggling to breathe, since oxygen is not transferred to the blood and it causes terrible pain in the chest.

The treatments are fairly obnoxious: intravenous anticoagulants (blood thinners), followed by oral blood thinners like warfarin. While they carry risk of bleeding and other long-term risks, it's better than dying.

Would you bet that a "nutritional supplement" manufacturer's vague claims and lack of data are sufficient proof to treat a life-threatening condition? You're a fool if you are.

Anyone reading these pages knows that I am a vigorous supporter of nutritional supplements. I even consult for the nutritonal supplement industry. But I am also an advocate of TRUTH, not BS.

Here is a woman from England who inquired whether she should stop her husband's warfarin in favor of nattokinase. This is precisely the sort of thing that can happen because of the campaign of misinformation behind nattokinase.


Dr. Davis,

Thank you for your very interesting blogs, which I came across searching for natural alternative treatments to warfarin.

My husband has been following the low carb, high fat, real food regime over the past few years. He got off all the blood pressure and cholesterol drugs and never felt better. He even got his blood sugar down from a recorded high that we are aware of 13 nmol/L (234 mg/dol) to 6.1 nmol/L 109.8 mg/dl).

We were on holiday in the Caribbean. Just before our return home, we did a trip to a neighbouring island that included non-alcoholic fruit punches. They tasted great, but were very sweet. I broke my normal refusal to drink these things, but only had a couple of glasses. (After all, we were on holiday!) My husband believes he consumed around 1.5 litres of the stuff and now realises he was feeding his body a very toxic product – fructose. That night, he had an incredible toxic response and we only got him onto the plane with a visit to the hospital and a pain killer injection.

The symptoms of pulmonary embolism only showed 2 weeks later . . . and warfarin treatment was started. We would both like to use an alternative therapy if we can find someone with experience to provide the support.Do you know of any studies that support alternative options?

Do you know of any practitioners in the England who support a non-drug approach with an understanding of nutrition who we may be able to receive advice and support?

Glucophobia: The Novel

13. April 2010 William Davis (25)
Just kidding: No novel here. However, there is indeed a story to tell that should scare the pants off you.

If you haven't yet gathered that carbohydrates are a macronutrient nightmare, let me recount the list:


Carbohydrates increase small LDL particles
Or, in the cholesterol-speak most people understand, "carbohydrates increase cholesterol." It's counterintuitive, but carbohydrates increase LDL substantially, far more than any fat.


Carbohydrates increase blood sugar
Eggs don't increase blood sugar, nor do chicken, raw almonds, onions or green peppers. But a bowl of oatmeal will send your blood sugar skywards.


Carbohydrates make you fat
Carbohydrates, whether in the form of wheat flour in your whole wheat bread, sucrose in your ice cream, fructose in your "organic Agave nectar," or high-fructose corn syrup in your dill pickles. They all provoke de novo lipogenesis, or fat formation. They also stimulate insulin, the hormone of fat storage.


Carbohydrates cause glycation
High blood sugar, like the kind that develops after a bowl of oatmeal, triggers glycation, or modification of proteins by glucose (blood sugar). This is how cataracts, kidney disease, and atherosclerotic plaque develop. Small LDL is 8-fold more glycation prone than large LDL, providing a carbohydrate double-whammy.


Your glucose meter remains the single best tool to gauge the quality of your diet. Many people have horror stories of the shocking experiences they've had when they finally get around to checking their postprandial glucose.

Drama with the Dr. Oz Show

11. April 2010 William Davis (27)
A producer from the Dr. Oz show recently contacted my office. They asked whether we could supply them with a volunteer patient from either my practice or the Track Your Plaque program who would be willing to appear on the show and discuss heart disease prevention. They needed someone to commit within 24 hours.

Despite the short notice, we identified a volunteer. He flew to New York the following week where he was interviewed along with several other men and women, all of whom had heart disease (heart attacks, stents, etc.). However, as this young man is very slender and follows most of the Track Your Plaque principles (e.g., vitamin D and omega-3 fatty acid supplementation; no wheat, cornstarch, or sugars, no restriction of fat, etc.), he apparently received less attention than the overweight, I-know-nothing-about-diet interviewees.

Then there was an odd turn of events: Dr. Dean Ornish, apparently a friend of Dr. Oz, will be providing the dietary counseling. The producer had made no mention of Dr. Ornish.

Now that's an odd collision of philosophies: Our Track Your Plaque version of low-carb with the guru of low-fat, Dr. Ornish.

The following week, Dr. Ornish called me and graciously asked whether I was okay with this. I'm not sure just how much he knew about the philosophy I advocate, nor how much I have bashed his program as a destructive approach to diet, nor whether he knew that I gained 30 lbs on the Ornish diet, along with a drop in HDL to 27 mg/dl, increased triglycerides to 350 mg/dl, and type II diabetes that I've talked about on this blog and the Track Your Plaque book and website. I suspect he knew little to none of this.

Anyway, I tried to diplomatically explain that my patient's cause for coronary plaque was small LDL particles that he expressed despite his very slender build, likely from excessive carbohydrates, controlled with carbohydrate restriction. Dr. Ornish maintained his usual arguments: Grains are good, provided they are whole grains, heart disease is "reversed" with his diet program, etc. (I didn't want to challenge him in a phone call and tell him that he never actually reversed coronary plaque, but just reversed endothelial dysfunction. But, as Dr. Ornish is not a cardiologist, I wasn't sure how far his understanding of these issues went.)

We agreed to disagree. This leaves my poor patient in an odd position: Being asked by Dr. Ornish and the Dr. Oz show to follow a low-fat program for the sake of entertainment, or adhering to the advice we follow that has so far served him well, given his small LDL particle size tendencies.

We'll see where this little drama leads.

Response from Nature Made

10. April 2010 William Davis (31)
Here's the response from Nature Made when I emailed them about my concern that there appears to be no vitamin D in their vitamin D gelcaps.

It is the usually CYA corporate-speak that says nothing. The grammatical errors make it clear that this was a "canned" response.



Date: April 9, 2010
From: Marissa Reyes, Consumer Affairs Department
Subject: Reference #346236

Dear William Davis, MD:

We recently received your e-mail regarding Nature Made products. We regret to
hear that the quality standards of our company. [?]

Our company is called Pharmavite, and we manufacture Nature Made nutritional
supplements. We have been in business since 1971. We are committed to quality
control, and have very high quality standards. Our Quality Control personnel
sample and test all raw materials as they enter our plant, and again assay the
finished product, before final packaging.

Patients who come to the office do not provide me with the bottles nor lot numbers. In past, when I've gone to the trouble of doing this (with other companies, not Nature Made), it has come to nothing helpful. The information gets passed on to the company and we hear nothing and never learn if there was a problem, or receive some more corporate-speak letter saying everything was fine. This is obviously a liability-avoidance tactic: Admitting that something was wrong would open them up to legal risk. So, frankly, I can't be bothered.

So we are left with the unsatisfying experience of relying on street-level experiences.

For now, my advice: Avoid Nature Made vitamin D. Too many people have had blood tests demonstrating that they are not obtaining any vitamin D.

By the way, the Nature Made brand of fish oil is among the very few problem brands of fish oil we've encountered. Fish oil should be only mildly fish in smell and generally should not cause stomach upset and excessive belching if properly purified. Nature Made is excessively fishy when you smell it, suggesting oxidation. We've had repeated (dozens) of patients who have experienced difficulties with this brand. Rather than dealing with the frustrating gobbledy-gook of this company, just avoid their products.

What to Eat: The diet is defined by small LDL

9. April 2010 William Davis (15)
I approach diet from the perspective of small LDL particles.

Small LDL particles have exploded in frequency and severity in Americans. It is not at all uncommon to see 70% or more small LDL particles (i.e., 70% of total LDL particle number or Apo B) on lipoprotein testing. (I saw two people today who began with over 95% small LDL.)

Small LDL particles are:
--More likely to persist in the bloodstream longer than large LDL particles.
--More likely to adhere to components of atherosclerotic plaque.
--More likely to gain entry to plaque.
--More likely to be taken up by inflammatory white blood cells which, in turn, become the mast cells that fill coronary plaque.
--More likely to be oxidized.
--More likely to be glycated (8-fold more likely than large)

To add insult to injury, foods that trigger small LDL formation--i.e., carbohydrates--also cause high postprandial blood sugars. High postprandial blood sugars, in turn, glycate small LDL. That combination of events accelerates 1) plaque growth, 2) plaque instability, and 3) aging.

So carbohydrates trigger this sequence, carbohydrates of all stripes and colors. Not just "white" carbohydrates, but ALL carbohydrates. It's all a matter of degree and quantity. So, yes, even quinoa, bulghur, and sorghum trigger this process. I've only recently appreciated just how bad oats and oatmeal are in this regard--really bad.

Foods that trigger small LDL also trigger higher blood sugars; foods that trigger higher blood sugars also trigger small LDL. Small LDL and blood sugar are two different things, but they track each other very closely.

So, in the Track Your Plaque approach to diet, we craft diet based on these simple principles:

1) Eliminate wheat, cornstarch, and sugars--These are the most flagrant triggers of small LDL, blood sugar, and, therefore, LDL glycation.
2) The inclusion of other carbohydrates, such as oatmeal, quinoa, rye, etc. depends on individual sensitivity. Individual sensitivity is best gauged by assessing one-hour postprandial glucose.

Stay tuned for more in this series. Also, Track Your Plaque Members: We will be having an in-depth webinar detailing more on thees principles in the next couple of weeks.

Is it or isn't it vitamin D?

7. April 2010 William Davis (63)
Jackie takes 10,000 units of vitamin D(3) per day as a gelcap.

Her starting 25-hydroxy vitamin D blood level was 18.1 ng/ml. Severe deficiency, no surprise.

On her 10,000 units per day, Vitamin Shoppe brand, her 25-hydroxy vitamin D level was 76.2 ng/ml--perfect. It stayed in this range for about two years.

She then changed to the Nature Made brand gelcaps she picked up at Walgreen's. Repeat 25-hydroxy vitamin D level: 23 ng/ml.

This has now happened with five different people, all taking the Nature Made brand.

If you are taking this brand of vitamin D, please be on the alert. You might consider a 25-hydroxy vitamin D blood level to be sure it actually has the vitamin D it's supposed to have.

Or, change brands.
Does high cholesterol cause heart disease?

Does high cholesterol cause heart disease?

3. October 2008 William Davis (15)
How often does someone develop coronary heart disease from high cholesterol alone?

Believe drug industry propaganda and you'd think that everyone does. Physicians have bought into this concept also, driving the $27 billion annual sales in statin cholesterol drugs.

In my experience, I can count the number of people who develop coronary disease from high cholesterol alone on one hand. It happens--but rarely.

That's not to say that cholesterol is not an issue. That rant populates many of the kook websites and conversations on the internet that argue that high cholesterol is a surrogate for some other health issue, or that it is part of a medical conspiracy.

The problem with conventional measurement of cholesterol is that it ignores the particle size issue: whether particles are large or small. Small LDL are flagrant causes of coronary atherosclerotic plaque. Large LDL is a rather meager cause. Simple cholesterol measurement also ignores the presence of other factors that lead to heart disease, like lipoprotein(a) and vitamin D deficiency.

Conventional total and LDL cholesterol do not distinguish between large and small particles, nor reveal the presence of other hidden patterns. An LDL cholesterol of 150 mg/dl, for instance, may contain 100% large LDL--a relatively good situation that by itself is unlikely to cause heart disease, or it might contain 100% small LDL--a very bad situation that is likely to cause heart disease. Just knowing that LDL is 150 mg/dl tells you almost nothing. In 2008, most people have some mixture of the two, particularly with the proliferation of "healthy whole grains" in the American diet, foods that trigger formation of small LDL.

The imprecision and uncertainty of conventional total and LDL cholesterol has provided ammunition for some to discount the entire cholesterol concept. And they are right to a degree: cholesterol by itself is indeed a lousy predictor of heart disease. But small LDL is a very reliable predictor of potential for heart disease. Dismissing the entire concept because the standard measurement stinks is not right, either.

It is therefore an unfortunate oversimplification to say that high cholesterol causes heart disease or that it doesn't. It can--but not always, depending on size and other factors. In my view, it is therefore irreponsible to treat total or LDL cholesterol without knowledge of particle size. I've seen this play out many times: Someone with an LDL cholesterol of 150 mg/dl but all large still gets prescribed a statin drug by his/her doctor. Or someone with an LDL of 100 mg/dl--generally "favorable" by most standards--is not treated but it is all small and the person is truly at high risk. (Also, knowledge that all LDL particles are small does not mean that statins are the preferred agent. In my view, they are not.)

    I've had no success lowering my very high LDL(350), can't tolerate statins..supposedly have combination of large and small LDL, 20-40% blockages per cardiac cath.My HDL (80), Trig.(70)are good, but still concerned since already show athrosclerosis. I'm 55, 100 lbs., and have had high LDL since a teen. Any suggestions? Thanks!

    Isn't inflammation the root cause of atherosclerosis ? Isn't cholesterol's role in heart disease only that it happens to be used as the material, with which the body repairs the lesions caused by inflammation ?

    excellent post. 1. if statins not preferred way to go for small LDL, what is- Niacin and elimination of grains? 2. How is it possible that a VAP test showed large Pattern A(by small margin)and two years later NMR shows nearly 100% small dense Pattern B?  Is one test better than the other? 3. Do genetics overwhelmingly determine pattern size?  I have eliminated all grains,sugars, starchy veggies to see if i can get my LDL to be large and fluffy.  Thank you.

    I am an example of someone with "normal" cholesterol and CAD. I was only 54 years old when my LAD blocked. I went on to bypass as I reblocked after each stent.

    In the past few years I have been looking into many of the other factors may have contributed to my  health problems and trying to optimize my health. Yes, coromary heart disease is so much more than elevated cholesterol.

    Hi Dr Davis,

    Excellent post. The value of total cholesterol is irrelevant. While there is a VERY slightly higher cholesterol level in heart attack patients, the overlap with the normal population is such as to make total cholesterol level meaningless. Once it's meaningless and you can then look back to the initial work of Ancel Keys, who appears to have been the primary architect of the lipid hypothesis, and you can see it is based on this now clearly meaningless measurement.

    The very slight increase in TC in cardiac patients is explicable by the fact that glycation of the apoA particle inhibits its attachment to the LDL receptor. I would expect this to produce a slight rise in TC. You then have to pose the question as to which does most damage: persisting apoA containing particles due to glycation of their surface protein, or glycation of all of the body proteins by the same hyperglycaemia that affected the apo A protein. Using HbA1c as a marker of hyperglycaemia there is a reasonable correlation with CVD even within "normal" HbA1c levels in the EPIC study. Whole grains = hyperglycaemia. Hyperglycaemia = apoptosis of vascular endothelium. What more do you need for vascular damage?

    So, as the lipid hypothesis is based on TC and should have been stillborn or drowned at birth, where does particle size come in? We have the situation of good (HDL) cholesterol and bad (LDL) cholesterol to explain why TC is useless. Then we get good LDL (large fluffy) and bad LDL (small dense) to explain why total LDL (by calculation) is utterly useless too. We even now have good and bad HDL. Never mind good (small) VLDL and bad (large) VLDL to explain why some triglycerides are better/worse than others.

    Ultimately small dense LDL, large VLDL and HDL3 are strong markers of the metabolic syndrome. Hyperinsulinaemia and insulin resistance are the cornerstones of metabolic syndrome according to Reaven, who largely popularised the concept. The lipid changes are easily viewed as a consequence, not a cause, of metabolic syndrome. It is undoubtedly believable that sdLDL is stickier/more oxidisable than other lipoproteins, but that becomes unimportant if it's not there in the first place, ie no metabolic syndrome. This would, simply, explain why reducing wheat products works to reduce sdLDL, unless they are replaced by equally insulinogenic "wheat free" comparable junk foods based on non wheat sugar sources. If it turned out that purple spotted LDL, induced by eating blackberries, was stickier than sdLDL we would no doubt have a drive to eliminate blackberries or (more likely) develop a drug to remove the purple spots.

    Following your blog gives me the distinct impression that one day you really could become a cholesterol skeptic. Stranger things have happened.

    Anonymous and Steve - I stronly believe in a propper low carb (note that I say LOW carb, and not NO Carb) way of eating. I would really like to suggest some awesome reading material. It is from dr. James E Carslon who wrote the book "Genocide. How your doctors dietary ignorance will kill you!!!". In the book he explains amongst other things the actual benefits of dietary cholesterol and how a low-carb way of eating will increase the ldl-particle sizes and bring down the triglycerides and dangerous VLDL.

    From a recent personal answer I got from him, he explained to me the benefits of adding dietary cholesterol from a biochemical point of view. I hope this helps in understanding that a correct dietary change can help.

    Here is what he said :

    OK, so what are the benefits of adding cholesterol to the diet? It's not only fascinating, it'll blow your mind. When we eat cholesterol containing foods, the cholesterol in the food we consume actually binds to an enzyme called HMG CoA reductase and inhibits its function. This enzyme is what's known as the rate limiting enzyme in cholesterol biosynthesis. This means that once this enzyme does what it's supposed to do, cholesterol will be made no matter what. By inhibiting the enzyme's function, choilesterol cannot be made. So eating cholesterol actually inhibts its own production.
    But wait, it gets even better.

    The cholesterol in the foods we eat is what's referred to as fat soluble, or lipophilic (or fat loving). Since cholesterol is lipophilic, it diffuses through not only the outer cell membrane, but the cell's=2 0nucleus membrane and attaches the the DNA. Guess where it attaches to on the DNA? It attaches to the sites on DNA WHERE HMG Co A IS MADE!!!!! That's right, so not only does the cholesterol in the food we eat attache and inhibit the function of the enzyme already present to make cholesterol; the cholesterol in the foods we eat also prevents the production of the enzymes needed to make itself. In biochemical speak, this is known as negative biofeedback.

    Eat more cholesterol, make less cholesterol. By the way, the only thing I've seen in eighteen years considerably raise the good cholesterol known as the HDL, is the consumption of more cholesterol. So EAT MORE CHOLESTEROL IT"S GOOD FOR YOU!

    Inflammation is essentially the cause of heart disease isn't it?
    I'm not medically trained, but I assume small particle LDL is a signifier of crammed, broken up large particles - perhaps a long time accumulation of what was once sent to the skin hoping to be converted to D by UVB but didn't(there is a study that says British gardeners have lower cholesterol in the Summer which seems very interesting).
    The fact that statins work (albeit with alarming side effects), and that according to a Spanish study, that atorvastatin raises vitamin D some degree shows the problem isn't really cholesterol. That is erroneous cholesterol readings are the 'symptom' of either vitamin D deficiency or associated things that domino on to the ability for the heart to succomb to heart disease. As a rule I still think the general cholesterol hypothesis is a farce, not just because of the way the products are marketed but because it's only looking at one station on the tube system. 'High cholesterol causing heart disease' might be better termed as 'low vitamin D causes heart disease' because that's perhaps the root, or at least one root.

    Dr. Davis,

    First let me say a big thank you for your blog.  I follow your's, Jimmy Moore's and the Drs. Eades' blogs closely.  As a result of reading your book and blot, I just had my first heart scan at age 50, and was vert happy to hear zero calcium score.

    I do low carb nutrition (~50g/day), so my triglycerides were very low (28).  I've read that all LDL will be large with triglycerides that low (below 70).  Can you confirm that?  Would I be wasting my money on blood work to determine particle size?  HDL is 62, LDL 136.

    Simple cholesterol measurement also ignores the presence of other factors that lead to heart disease, like lipoprotein(a) and vitamin D deficiency.

    Conventional total and LDL cholesterol do not distinguish between large and small particles, nor reveal the presence of other hidden patterns. An LDL cholesterol of 150 mg/dl, for instance, may contain 100% large LDL--a relatively good situation that by itself is unlikely to cause heart disease, or it might contain 100% small LDL--a very bad situation that is likely to cause heart disease. Just knowing that LDL is 150 mg/dl tells you almost nothing. In 2008, most people have some mixture of the two, particularly with the proliferation of "healthy whole grains" in the American diet, foods that trigger formation of small LDL.

    I'm looking for heart disease info that isn't related to cholesterol OR grain intake, because my cat has it--cats are obligate carnivores, and therefore do not take in grains unless fed commercially-prepared foods.  Mine do not--I make their food from scratch, using a UC Davis vet-designed diet recipe.  Cholesterol levels aren't a concern either, although I now know to have the SIZE of cells examined, as well as vitamin D levels checked.  As for anti-inflammatories, fish oil is part of the diet recipe.

    I'm going back to the vet for more blood work (now that I have more clues).

    Statins Do Not Decrease Small, Dense Low-Density Lipoprotein
    Free full text at link.
    In an observational study, we examined the effect of statins on low-density-lipoprotein (LDL) subfractions.
    Using density-gradient ultracentrifugation, we measured small, dense LDL density in 612 patients (mean age, 61.7 ± 12.6 yr), some with and some without coronary artery disease, who were placed in a statin-treated group (n=172) or a control group (n=440) and subdivided on the basis of coronary artery disease status.
    Total cholesterol, LDL cholesterol, apolipoprotein B, and the LDL cholesterol/apolipoprotein B ratio were significantly lower in the statin group. However, the proportion of small, dense LDL was higher in the statin group (42.9% ± 9.5% vs 41.3% ± 8.5%; P=0.046) and the proportion of large, buoyant LDL was lower (23.6% ± 7.5% vs 25.4% ± 7.9%; P=0.011). In the statin group, persons without coronary artery disease had higher proportions of small, dense LDL, and persons with coronary artery disease tended to have higher proportions of small, dense LDL.
    Our study suggests that statin therapy—whether or not recipients have coronary artery disease—does not decrease the proportion of small, dense LDL among total LDL particles, but in fact increases it, while predictably reducing total LDL cholesterol, absolute amounts of small, dense LDL, and absolute amounts of large, buoyant LDL. If and when our observation proves to be reproducible in subsequent large-scale studies, it should provide new insights into small, dense LDL and its actual role in atherogenesis or the progression of atherosclerosis.

    The imprecision and uncertainty of conventional total and LDL cholesterol has provided ammunition for some to discount the entire cholesterol concept. And they are right to a degree: cholesterol by itself is indeed a lousy predictor of heart disease. But small LDL is a very reliable predictor of potential for heart disease. Dismissing the entire concept because the standard measurement stinks is not right, either.

    For years I suffered from high cholesterol and was almost permanently on statin medication. I come for a family with a strong history of heart disease and I personally believe that high cholesterol can cause heart disease. Thankfully I now have my cholesterol under control but it has been hard work, and I done it the natural way, as I suffered from the side effects statins cause.

    About eighty percent of our cholesterol is produced by the liver and the rest depends on our diet. Foods such as red meat and butter are rich in cholesterol where as those from plant origin have very little or no cholesterol at all. The control of cholesterol in our body is done by the liver. I think,more can be found out from:
