Egg Food Facts
There are three grades for eggs: U.S. Grade AA, U.S. Grade A, U.S. Grade B. All egg cartons that are marked "A" or "AA" are not officially graded. Egg cartons must have the USDA grade shield to have been officially graded.
The difference in the quality of eggs can be determined by the amount of spread when they are broken. U.S. Grade AA eggs will have a small spread, be thick, very white and have a firm high yolk. U.S. Grade A eggs will have more spread with a less thick white. U.S. Grade B eggs will have a wide spread, little thick white and probably a flat enlarged looking yolk. U.S. Grade C eggs have an even wider spread with a thin watery white.
Studies have shown that egg yolks have less cholesterol than previously thought. They have been revised from 250mg to 200mg.
