That Just Might Be A Good Egg

LOS ANGELES - In June, the consumer group Center for Science in the Public Interest blew its top -- excoriating egg companies in a news release for adding omega-3 fatty acids to their eggs (via nutrients added to the hens' feed) then trumpeting the eggs' nutritional fabulousness. An egg contains just more than 200 milligrams of dietary cholesterol, above the dietary limit set by the American Heart Assn. for people at increased risk of heart disease.

Good egg, or bad egg?

The center was angered because at least some of the egg companies add a flaxseed-derived omega-3 called AHA to the feed. This, although an omega-3, is only inefficiently converted to the DHA and EPA omega-3s that help the heart. The group was equally outraged at the idea that eggs, with all their cholesterol, would be considered a healthful delivery system.

But, in fact, they may just be.

The main dietary culprit in raising cholesterol is not the cholesterol we eat, says Dr. Joseph Keenan, a professor of medicine and cholesterol researcher at the University of Minnesota. A diet high in saturated fats has a far greater effect on the bad, or LDL, cholesterol in our bloodstream. That's partly because our bodies use only 25% of the cholesterol we eat but 75% of cholesterol in the bloodstream.

Some researchers say that the confusion over blood cholesterol and dietary cholesterol may have resulted in the egg getting a far worse reputation than it deserves. Eggs, they note, are inexpensive, full of protein and contain high levels of lutein and zeaxanthin, which may protect against blindness from macular degeneration.

A recent issue of Nutrition Source, a consumer bulletin published by the Harvard School of Public Health, ticked off a few more egg attributes, including the vitamins B12 and D, riboflavin and folate, which may help lower the risk of heart disease.
