When we take in extra isolated protein our body does not assimilate all of it. Many protein chains do not get broken down and become harmful free radicals. During the breaking down process the nitrogen becomes ammonia which the body has to dispose of. Too much protein makes the body toxic with ammonia. Our bodies make protein when it is needed from amino acids. Our body makes 11 of these amino acids which are called non essential. The other nine amino acids which are essential are derived from plants. Protein from animals is acidic and harder to digest. This makes for inflammation causing stress on the kidneys and liver.
