Mr. Jiang from Huai 'an, Jiangsu usually likes fitness. In order to keep fit, he often eats a lot of protein. Recently, Mr. Jiang felt unwell and went to the hospital for examination. The doctor diagnosed him as nephritis caused by protein's excessive intake. Protein is an important nutrient needed by human body, and protein is an important component of human muscles and bones. So now many fitness experts are popular to add a lot of protein to build a perfect figure, but taking too much protein will also do harm to the body.

Different people have different intake of protein. For ordinary people, protein intake of about 1 g per kilogram of body weight can meet human needs. For people who need to gain muscle, the intake of protein is about 1.5g per kilogram of body weight. Although protein is good for the human body, it must take in a proper amount of income, and protein may do harm to the human body.
