When protein is overdosed, urinary calcium excretion will increase, thus increasing the risk of kidney calculi. Fitness people take a lot of high-protein health care products or foods such as protein powder and egg white after muscle training, which also has similar dangers.

Excessive intake of protein is harmful to human health. There are many decomposition products of protein in human body, among which ammonia, ketoacid and urea will have side effects on human body, which will not only increase the burden on the liver, but also easily cause indigestion, which will affect the function of liver and kidney for a long time, leading to emaciation and low immune function.

Extended data:

Protein doesn't need to add anything:

In the Reference Intake of Dietary Nutrients for China Residents, it is recommended that the daily protein intake of adults should be 65 ~ 90g, or 10% ~ 12% of total energy, which can meet the metabolic needs. In addition, protein intake varies with people's age, weight and labor intensity.

Protein is the most important nutrient for human body. It is not only the main component of human body, but also can be converted into sugar and fat to provide energy under certain conditions. The best food sources in protein are fish, meat, eggs, milk, soybeans and nuts.

Protein in food has a large molecular weight and needs to be digested into small amino acids in the small intestine before it can be absorbed into the blood and the human body.

Therefore, all protein entering the gastrointestinal tract, whether it is protein in meat, eggs and milk, or so-called health products such as protein powder (including soybean protein powder and whey protein powder), collagen, immune protein (bovine colostrum) and sea cucumber, will be digested into small molecular amino acids. Once protein is digested into amino acids, it will lose all its original activities and functions and become an out-and-out "dead substance".

Therefore, as long as people are healthy, eat a normal diet, eat a normal amount, and are not picky eaters, they can get enough protein from natural foods, eat real food as much as possible, and don't have to eat extra protein powder.

People's Network-Protein powder is not magical, and it is harmful to eat at will.
