Evaluation of the amino acid composition of meat protein shows that beef is an excellent source of all of the amino acids required by man.
Beef can supply all the essential amino acids the body needs to build, maintain and repair body tissue and muscle, form hormones and enzymes and increase resistance of infection and disease.
In respect of the essential amino acids, beef would appear to have a somewhat higher content of leucine, lysine and valine than pork or lamb and a lower content of threonine.
The study also shows that amino acids in beef are not destroyed during cooking.
Beef protein in amounts as great as 55% of the diet will not raise cholesterol levels in normal men.
The real danger of high protein, high meats diet is that they are frequently accompanied by a high consumption of refined carbohydrates.
Different proteins are composed of varying concentration of different amino acids, so a blend of proteins sources, if chosen wisely, provides an even distribution and concentration of the amino acids necessary for optimal growth.
