Eggs contain all of the eight essential amino acids (the
type that your body cannot make from other substances) and
very high levels of total amino acids - especially important
sulfur-containing aminos. Eggs are also readily digested
and absorbed. As a lactose-free protein source, eggs are
often more tolerable to people who have trouble with dairy
foods. For these and other reasons, eggs have been a staple
of bodybuilders diets since the beginnning of the sport.
