For a period of time, eggs were considered a big no-no, according to doctors. That's because just two eggs contained enough cholesterol to put you over your daily recommended value. So then it was advised that you could cut out some of your cholesterol by removing all of the yolk and using just the whites.
More and more research shows that eating an egg or two a day will not raise your cholesterol levels, as once previously believed. Go figure! Also, most of the protein and all the good nutrients are found in the yolk of an egg. I still suggest to my clients to mix it up. For an individual who is going to to have four eggs...I will suggest that they have 2 eggs with yolk and 2 eggs with no yolk. Much of this research shows what has been learned is that most blood cholesterol is made by the body from dietary fat, not dietary cholesterol.
Take advantage of eggs and their powerful makeup of protein. The protein found in eggs has the highest "biological value" of protein--a measure of how well it supports your body's protein need--of any food. In other words, the protein in eggs is more effective in building muscle than protein from other sources, even milk and beef. Eggs also contain Vitamin B12 which is necessary for fat breakdown.
