Generally speaking, 0.6/kg of protein per day can satisfy the physiological needs of the body, and 30-36g of protein per day is sufficient. Protein food selection, should be fish, lean meat, chicken, milk-based, as far as possible to eat as little as possible containing plant protein substances such as peanuts, soybeans and soybean products, etc., because the plant protein contains non-essential amino acids, too much to eat in the supply of nutrients, but will aggravate the phenomenon of urinary protein.
