What is the nutrient content of eggs?
Eggs are an excellent, inexpensive source of high-quality protein and nutrients such as Vitamin B12, riboflavin, Vitamin D, folacin, and choline. Eggs have some iron, although it may not be absorbed as readily by the body than other sources of iron (eating eggs with foods high in Vitamin C like citrus fruits, peaches, papayas, sweet red peppers, berries, broccoli, and peas can help the absorption of iron).
The nutrients of eggs are not equally distributed between the egg whites and egg yolks. While egg whites offer the highest protein concentration and some B vitamins, most of the nutrients and minerals are found in the highest level in the egg yolks. Your best bet to get the full nutritional benefits of eggs – eat whole eggs.
