Common dietary fat and intestinal microbes linked to heart disease

A new pathway has been discovered that links a common dietary lipid and intestinal microflora with an increased risk of heart disease, according to a Cleveland Clinic study published in the latest issue of Nature.

The study shows that people who eat a diet containing a common nutrient found in animal products (such as eggs, liver and other meats, cheese and other dairy products, fish, shellfish) are not predisposed to cardiovascular disease solely on their genetic make-up, but rather, how the micro-organisms that live in our digestive tracts metabolize a specific lipid -- phosphatidylcholine (a component of lecithin). Lecithin and its metabolite, choline, are also found in many commercial baked goods, dietary supplements, and even children's vitamins.

The study examined clinical data from 1,875 patients who were referred for cardiac evaluation, as well as plasma samples from mice. When fed to mice, lecithin and choline were converted to a heart disease-forming product by the intestinal microbes, which promoted fatty plaque deposits to form within arteries (atherosclerosis); in humans, higher blood levels of choline and the heart disease forming microorganism products are strongly associated with increased cardiovascular disease risk.

"When two people both eat a similar diet but one gets heart disease and the other doesn't, we currently think the cardiac disease develops because of their genetic differences; but our studies show that is only a part of the equation," said Stanley Hazen, M.D., Ph.D., Staff in Lerner Research Institute's Department of Cell Biology and the Heart and Vascular Institute's Department of Cardiovascular Medicine and Section Head of Preventive Cardiology & Rehabilitation at Cleveland Clinic, and senior author of the study. "Actually, differences in gut flora metabolism of the diet from one person to another appear to have a big effect on whether one develops heart disease. Gut flora is a filter for our largest environmental exposure -- what we eat."

Dr. Hazen added, "Another remarkable finding is that choline -- a natural semi-essential vitamin -- when taken in excess, promoted atherosclerotic heart disease. Over the past few years we have seen a huge increase in the addition of choline into multi-vitamins -- even in those marketed to our children -- yet it is this same substance that our study shows the gut flora can convert into something that has a direct, negative impact on heart disease risk by forming an atherosclerosis-causing by-product."

In studies of more than 2,000 subjects altogether, blood levels of three metabolites of the dietary lipid lecithin were shown to strongly predict risk for cardiovascular disease: choline (a B-complex vitamin), trimethylamine N-oxide (TMAO, a product that requires gut flora to be produced and is derived from the choline group of the lipid) and betaine (a metabolite of choline).

"The studies identify TMAO as a blood test that can be used in subjects to see who is especially at risk for cardiac disease, and in need of more strict dietary intervention to lower their cardiac risk," Dr. Hazen said.

Healthy amounts of choline, betaine and TMAO are found in many fruits, vegetables and fish. These three metabolites are commonly marketed as direct-to-consumer supplements, supposedly offering increased brain health, weight loss and/or muscle growth.

These compounds also are commonly used as feed additives for cattle, poultry or fish because they may make muscle grow faster; whether muscle from such livestock have higher levels of these compounds remains unknown.

"Knowing that gut flora generates a pro-atherosclerotic metabolite from a common dietary lipid opens up new opportunities for improved diagnostics, prevention and treatment of heart disease," Dr. Hazen said. "These studies suggest we can intelligently design a heart healthy yogurt or other form of probiotic for preventing heart disease in the future. It also appears there is a need for considering the risk vs. benefits of some commonly used supplements."

I was considering using Mitolipin and or adding more Choline rich foods but I do already have severe disbiosis so not sure what to make of this.

What is the bacteria? Most heart patients have had antibiotics at some point in there life. Did this not handle that bacteria?

According to this article ...
Eggs, Too, May Provoke Bacteria to Raise Heart Risk
the specific strain is not known yet. "...the specific bacteria responsible for the increase in TMAO are not yet identified."

It's more the byproduct that is the problem. It's called trimethylamine N-oxide. And it appears it appears the effects of this can be negated with DMB a "non-toxic chemical compound called DMB that prevents gut bacteria from converting certain nutrients into a harmful chemical that negatively affects heart and brain health" Found in Olive oil and some red wine.
One way to realize this TMAO is being formed in the body is by a fishy smell.

There is something a little fishy (lol) here. It appears this Dr. Hazen (the person responsible for conducting this research) is also formulating an ultra potent Olive oil based supplement to inhibit this TMAO from being formed. The MEBO Blog: Resveratrol, DMB & Breath and Body Odor He is in business with Proctor Gamble. So that's a red flag.

Bottom line, I guess this TMAO could be considered an endotoxin. And we all know there are ways to deal with endotoxin. Including antibiotics as Tarmader mentioned.

My concern comes with supplementing additional choline and how to know how much to take.


Thank you Mito. I will consider this as I do apparently need additional choline (per diagnostic results). And with the info that adequate Vit. C (which I'm also verifiably low in) helps to prevent bleeding issues associated with aspirin (together with Vit K), which I only found out about recently, aspirin is back on the menu!

Ahh, it's always nice when you get the finely tailored product at $69.99 along with the study.

vitamin C stops bleeding from aspirin??
