Notes on: "The Park Avenue Diet Show: Eggs-istentialism"; October 10, 2010

Misinformation and misunderstanding about eggs represent errors in thinking that confuse the American public and lead to poor nutritional recommendations. For several decades many people have been lead to believe that eggs cause hardening of the arteries, coronary artery disease, strokes and other cardiovascular abnormalities. The simplistic reason? Since eggs contain cholesterol, they are inherently unhealthy.

The truth is quite the opposite: cholesterol is not a poison but an important component of many crucial bodily hormones. Moreover, as has been determined from research on the metabolic syndrome, weight gain and high calorie diets trigger insulin resistance which in turn elevates dangerous lipoprotein levels in the bloodstream.

What do you eat for breakfast? If you check out the breakfast menu of your local fast food franchise, you will find numerous items whose caloric content may be seven to ten times more than that of a hard boiled egg. For people struggling with weight, a high protein, low calorie food is indeed the perfect choice, and that’s exactly what eggs are.

Here are several scholarly articles on the subject. Note that in no case do the researchers recommend egg-white omelets or avoiding eggs entirely.

The first article, dating from 1999, was a trailblazing study that upset the nutritional applecart. Egg consumption was found to have any impact on the risk of serious cardiovascular illnesses.

A more recent article in The American Journal of Clinical Nutrition came to the same exact conclusion. Here the blame for atherosclerotic disease is attributed to saturated fats and trans fats. The latter two are supplied in abundance in those 1,000 calorie breakfasts that many Americans unreservedly embrace.

An article in Circulation in 2008 studied the effect of egg consumption on heart failure. Once again there was no causal relationship.

Here is the most important study that we discussed this week, published in the journal Risk Analysis. Eating one egg per day is responsible for less than 1% of the risk of coronary heart disease in healthy adults. On the other hand, poor lifestyle choices (unhealthy diet, smoking, obesity, physical inactivity) contribute 30-40% of heart disease risk. The remaining 60-70% of heart disease risk is due to unavoidable factors (genetics) and potentially treatable risk factors (diabetes, high blood pressure). Next to those numbers, the 1% risk attributed to eggs seems extraordinarily small. Perhaps someone can explain why diabetes is treated so flippantly in some circles—on “diet” magazine covers that promote “healthy” chocolate cakes—yet eggs are still considered nutritional pariahs.

The larger issue, once we accept the fact that eggs have a place in virtually everyone’s diet, is: where does the average American turn when there is so much misinformation in our media-cluttered society? Unfortunately, it is up to you to refer to trusted sources of health information exclusively, no easy task. Sorting through supposedly conflicting data and controversial issues—that’s my responsibility. Your responsibility? Eat a healthy breakfast!
