Eggs represent one of the least expensive forms of high-quality protein and one important source of vitamins B12 and E, riboflavin, folacin, iron, and phosphous. (I currently pay about 2¢ for 1g of protein from egg white--that's $1.51 per 18-pack of eggs.) This collective attribute set makes it one of nature's near-perfect foods. It does have one drawback however: The yolk contains 233 mg of
dietary cholesterol.
When the world began to be more cholesterol-conscious, egg consumption dropped dramatically. In recent years, however, research has shown that saturated fat has a greater effect on
blood cholesterol levels than dietary cholesterol does. A single large chicken yolk offers only 1.5 grams of saturated fat (by comparison a quarter-pound hamburger patty with an ounce of cheese contains about 6.0 grams of saturated fat).
What is cholesterol?
Cholesterol is a fat-like substance found in every living cell in the body. It is made in necessary amounts by the body and is stored in the body (especially concentrated in the liver, kidney, adrenal glands and the brain). Your body produces all the cholesterol it needs. Most of the cholesterol found in the blood and tissues come from this internal synthesis.
Generally the body compensates for changes dietary cholesterol by 1) synthesizing smaller amounts in the liver, 2) by excreting more, or 3) by absorbing less dietary cholesterol.
Additional studies on the connection between dietary and blood cholesterol indicate that only some people are sensitive to dietary cholesterol (that is, their bodies don't properly adjust for increases in dietery cholesterol). For others, blood cholesterol level appears to be much less affected by dietary intake.
