This dietary assumption is wrong and can even be harmful, as a quick study of the facts about vegetable protein and nutrition shows. The Importance of Protein Protein is essential to human health. As suggested by the differences between our muscles and our fingernails, not all proteins are alike. This is because differing combinations of any number of 22 known amino acids may constitute a protein.
Amino acids are a fundamental part of our diet.
Non-animal foods can easily provide us with the necessary protein. Despite the claims of the meat and dairy industries, only 2.5-10 percent of the total calories consumed by the average human being needs to be in the form of protein. Eating too much protein can result in osteoporosis and kidney stones. Meat and dairy products raise the acid level in human blood, causing calcium to be excreted from the bones to restore the body's natural pH balance. This calcium depletion results in osteoporosis, or weakening of the bones.
