Question from The Times of India

"Is it harmful to have the yolk of egg? If I mix one yolk with the whites of five eggs in my breakfast omelets, would that be okay or am I still asking for cholesterol problems?"

- Rushad Bana

"No, consuming the yolk is not totally harmful, especially if not eaten daily. Yes, the yolk contains most of the fat (99 per cent) of the egg, but it also contains a chunk of the nutrients, including 90 per cent of the calcium, iron, Vitamin B6 + B12, zinc, and folate content. Majority of the protein (100 per cent complete in all essential amino acids) content is in the egg white, and since it has just 1 per cent of the fat; it contributes very little calories to the daily intake. Thus egg whites can be had in multiple numbers daily."

Eggs and Their Affect (or lack thereof) on your Cholesterol Levels

"Many people have heard the claims that egg yolk contains too much cholesterol, thus should not be eaten. An interesting study was done at Purdue University a number of years ago to test this. Men in one group each ate an egg a day, while men in another group were not allowed to eat eggs. Each of these groups was further subdivided such that half the men got “lots” of exercise while the other half were “couch potatoes.” The results of this experiment showed no significant difference in blood cholesterol levels between egg-eaters and non-egg-eaters while there was a very significant difference between the men who got exercise and those who didn’t."

"How much cholesterol eggs give a person depend...

...on what the hen laying the eggs eats, researchers in Israel say.

"Dr. Niva Shapira of Tel Aviv University's School of Health Professions and colleagues designed feeds that were high in antioxidants and lower in omega-6 fatty acids, based on wheat, barley and milo.

"The specialized feed was given to young hens who had not yet accumulated omega-6 fatty acids in their tissues, and the composition of their eggs was then tested. Once the desired composition of low omega-6 and high antioxidant eggs was achieved they were given to study participants, who were instructed to eat two of these special eggs daily."
