    I suspect you're probably right. I'm still waiting to hear from a local and well known scientist whom I e-mailed and asked to weigh in on the debate, but he's away on vacation until September. In the meantime, I don't think Mercola's name adds anything to the argument:

  3. It's true you can't put too much on this study, I just read the summary and from that it seemed like a narrow view. And you do have to look at the preponderance of evidence and take into account the many other egg studies. I used to read Mercola but he mixes his personal unproven view point as facts. And he's a little nutty also.

    Eggs, Too, May Provoke Bacteria to Raise Heart Risk

    By GINA KOLATA


    For the second time in a matter of weeks, a group of researchers reported a link between the food people eat and bacteria in the intestines that can increase the risk of heart attacks.

    Two weeks ago, the investigators reported that carnitine, a compound found in red meat, can increase heart disease risk because of the actions of intestinal bacteria. This time they reported that the same thing happens with lecithin, which is abundant in egg yolks.

    The lecithin study, published Wednesday in The New England Journal of Medicine, is part of a growing appreciation of the role the body’s bacteria play in health and disease. With heart disease, investigators have long focused on the role of diet and heart disease, but expanding the scrutiny to bacteria adds a new dimension.

    “Heart disease perhaps involves microbes in our gut,” said the study’s lead researcher, Dr. Stanley Hazen, chairman of the department of cellular and molecular medicine at the Cleveland Clinic Lerner Research Institute.

    In the case of eggs, the chain of events starts when the body digests lecithin, breaking it into its constituent parts, including the chemical choline. Intestinal bacteria metabolize choline and release a substance that the liver converts to a chemical known as TMAO, for trimethylamine N-oxide. High levels of TMAO in the blood are linked to increased risk of heart attack and stroke.

    To show the effect of eggs on TMAO, Dr. Hazen asked volunteers to eat two hard-boiled eggs. They ended up with more TMAO in their blood. But if they first took an antibiotic to wipe out intestinal bacteria, eggs did not have that effect.

    To see the effects of TMAO on cardiovascular risk, the investigators studied 4,000 people who had been seen at the Cleveland Clinic. The more TMAO in their blood, the more likely they were to have a heart attack or stroke in the ensuing three years.

    Carnitine — the red meat chemical — and lecithin are chemically related, Dr. Hazen said. As with lecithin, when carnitine is digested, choline is released and can be acted on by intestinal bacteria.

    The results of the new studies, though, do not directly prove that reducing TMAO protects against heart disease. That would require large studies following people who lowered their TMAO levels, which should be possible with a vegetarian or high-fiber diet.

    Dr. Hazen said that people who are worried about heart attacks may want to consider reducing lecithin and choline in their diet, which would require eating less of foods high in fat and cholesterol. Dr. Hazen said it also may be wise to avoid supplements or vitamins with added choline.

    In an accompanying editorial, Dr. Joseph Loscalzo of Brigham and Women’s Hospital in Boston suggested that in the future there may be other ways to reduce blood levels of TMAO. People might take probiotics to help grow bacteria that do not lead to an increase in TMAO. Or perhaps drugs could squelch the synthesis of TMAO. Those probiotics and drugs, though, do not yet exist, and even the specific bacteria responsible for the increase in TMAO are not yet identified.

    egg is a new fresh life.

    so its gotta be baaaaad.
    now, pharma pills! folks, its the real deal. extremely heathly. you have to visit your MD and inject radiation therapy so you could live up to 55, which is 5 years more than in dark ages = progress.

    and don't forget sun is extremely harmful to humans. you should work at least from 9 to 6 in corporate office and on weekends visit your church, shopping mall or restaurant where you can eat some healthy vegetable oil and diet coke.

    remember, government want all the good for you, little sheeople...

  7. I guess you didn't find the article interesting or thought provoking.

  8. Don't know about eggs in particular, but fatty foods have been demonized for no apparent reason. Fatty foods are the same foods that produce TMAO, but there's no increase in heart disease in large-scale studies.

    "If saturated fat doesn't adversely affect cardiovascular health, what does? Sorry, Nabisco: We should be giving a closer look to foods with a high glycemic index—a measure that reflects a food's influence on blood sugar levels, based on how quickly it is digested and absorbed. Typically, that means carbohydrates like cereal, bread, chips, and cookies.

    Will this new research on fat and carbs will be reflected in the 2010 Dietary Guidelines? According to Meir Stampfer, a Harvard professor of nutrition and epidemiology who worked on the 2000 guidelines, scientists on this year's committee know perfectly well what the evidence says. But few researchers want to shake the status quo or risk confusing the public. Robert Post, deputy director of the U.S. Department of Agriculture Center for Nutrition Policy and Promotion, admits that when it comes to nutritional recommendations, "simple messages, few messages, targeted messages, are very important." Ultimately, then, policymakers have to choose between keeping the message consistent and actually getting it right."

  10. The same foods that are high in saturated fats are high in carnitine (meat, eggs, etc). If this new theory is true, the same people that are eating saturated fats are eating high amounts of carnitine and they should be getting heart disease at a higher rate -- but they're not.
