Proteins are made of amino acids. There are 21 amino acids, out of which 9 are essential (that which our body cannot produce and hence is obtained from diet). They are histidine, isoleucine, leucine, lycine, methionine, phenylalanine, threonine, tryptophan and valine. The others are called nonessential amino acids (that which our body can make). These are alanine, asparagine, aspartic acid and glutamic acid, arginine, cysteine, glutamine, glycine, ornithine, proline, serine and tyrosine.
Animal sources such as meat, sea food, poultry are good source of protein. Animal protein is superior to the plant protein as it is considered to be complete because it contains all the essential amino acids. However, many animal proteins are high in fat content and too much consumption of these may lead to health issues like heart disease, blood pressure issues, and even insulin resistance. Excess animal proteins can also promote the production of uric acid, which can lead to joint pain and inflammation.
