Recently, with the opening of the curtain of the Beijing Winter Olympics, a wave of winter sports for the whole people has been set off. Many fitness enthusiasts like to take protein powder to increase muscle mass, but the amount of protein powder is too much, exceeding the needs of the human body, which will increase the burden on liver, kidneys and other organs, which is not good for physical health. Professor Ma Guansheng of the Department of Nutrition and Food Hygiene, Peking University Medical College, takes you to a scientific understanding of protein powder.
First, healthy people do not need to supplement protein powder as long as their diet is reasonable.
Second, high-intensity manual workers, athletes, people with weak bodies and weak digestive functions, and vegetarians can use protein powder as a nutritional supplement.
Third, both soy protein and whey protein are high-quality proteins.
Fourth, if the protein powder is consumed in excess, the excess protein is decomposed by intestinal bacteria, which may form harmful substances, produce acid, produce gas, and cause gastrointestinal discomfort.
