Eggs As Bad As Smoking: Really?

Written by Wellness Club on August 15, 2012 – 1:26 pm -

Sensational Headline Says Eating Eggs Is “Almost” As Dangerous As Smoking. So, What’s The Truth?


Dr. Myatt answers patient questions – with a forward by Nurse Mark


It seems that a Canadian researcher and professor at the University of Western Ontario by the name of Dr. John David Spence is once again enjoying a few minutes basking in the glow of media attention. In a press release titled “Research finds egg yolks almost as bad as smoking” which discusses a research article by Spence and co-researchers Jenkins and Davignon titled “Egg yolk consumption and carotid plaque” the doctor continues his long-standing crusade against cholesterol, eggs, and egg yolks in particular with a retrospective study that asked participants to remember how many eggs they ate and how many cigarettes they smoked in past years.

It is no surprise that the press worldwide has seized upon this rather dramatic headline and parroted it in sensational article after sensational article, panicking their readers and leading a number of our HealthBeat News readers to write us to ask for the truth.

One of those who wrote is a university professor, scientist, and doctor who is also a patient of Dr. Myatt. Since his diet is now The Myatt Diet and liberally includes eggs he was concerned that there might be any basis to this research.

Here is Dr. Myatt’s answer to Dr. Keith:


Let’s look at this “study.” It wasn’t an intervention study, it was a retrospective, “questionnaire” study.

That means it is in the same category as “The Rooster Crowing Brings the Sun Up.” Please read here to remind yourself how this works. This is an excellent article if I do say so myself.

Secondly, other variables were not examined. Do egg yolks really cause atherosclerosis in people consuming a low-carb diet? We don’t know if the remainder of diet composition makes a difference because that wasn’t looked at. Even the authors of the paper you cite state, “this hypothesis should be tested in a prospective study with more detailed information about diet, and other possible confounders such as exercise and waist circumference,” meaning other variables can cloud the issue.

I submit to you that the remainder of the diet makes a HUGE difference as to whether or not egg yolks or other cholesterol-containing foods have a deleterious effect.

Fats and cholesterol are not problem foods. They only become so when the diet is high in carbs. It is actually the carbs that are inflammatory and atherogenic. (1-4)

There’s been a lot of wrong things said about fats including saturated fats.

The “dietary cholesterol causes high cholesterol” debate is in serious question because the data which “support” this position are inconclusive, spotty and with much conflicting evidence. Read “Saturated Fats: Another Big Fat Lie” to learn more.

Finally, and not least of all, I have been using a low-carb diet with patients for 23 years now, which has given me the opportunity to observe how health changes including cardio risk factors, diabetes and even cancer. These things always get better when the diet is followed correctly. (Some people claim they are following the diet but an examination of a diet diary can reveal that they are cheating enough so as to be “not doing it”.)

Remember, for any question, you will find published studies on both sides of an issue. There is almost never “black and white” in medicine or in anything else. So one must consider the preponderance of evidence, and how well-done and interpreted the studies are, and if the researchers had any bias, etc. etc. Just because you find one contrary study about eggs does NOT a “smoking gun” make!

In case you want to see some evidence on the other side of the equation, here are just a few of the many scientific studies which show that low-carb diets –which typically include eggs “ad libitum” — prevent atherosclerosis and high-carb diets promote atherosclerosis. (see references 4-15)

And with this current defamation of eggs yolk, I must defend their honor. Egg yolks are chock-full of  “super nutrients” including:

  • lutein and zeaxanthin: two carotenoids which help protect the eyes from cataracts and macular degeneration.
  • choline: a B-vitamin-like essential nutrient needed for structural integrity, cell-signaling and acetylcholine synthesis. Choline is a major source of methyl groups which are are required for liver function, cellular replication, and detoxification reactions.
  • lecithin / phosphatidyl choline: needed for cell membrane integrity and intracellular communication
  • essential fatty acids, vitamins A, E, D, and K, calcium, iron, phosphorus, zinc, thiamin, B6, folate, B12, and panthothenic acid

Anything else I can clarify for you today? If not, go eat an egg…!!!

In Health,
Dr. Myatt
