When protein is overdosed, urinary calcium excretion will increase, thus increasing the risk of kidney calculi. When people eat too much fish and meat, but too little staple food and vegetables, it is easy to cause the problems of too little calcium, potassium and magnesium and too high sulfur and phosphorus in the diet, which leads to the increase of urinary calcium excretion and bone calcium dissolution.
In addition, at present, many women who love beauty take collagen beauty products in addition to three meals. Glycine and hydroxyproline rich in collagen may form oxalic acid after entering the human body. Excessive use will increase the oxalic acid content in urine, thus increasing the risk of kidney calculi. Another group of people who may have problems is the fitness group, and taking a lot of high-protein health care products or foods such as protein powder and egg white after muscle training has similar dangers.
Extended data:
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.
American scientists issued a statement saying that excessive intake of protein will increase the risk of cancer, such as rectal cancer, pancreatic cancer, renal cancer and breast cancer. Eating too much animal protein, such as eggs, milk and meat, can also induce heart disease. Patients with gout and liver and kidney failure should also limit the intake of protein.
Collagen is not a high-quality protein, and its nutritional value as protein is very low. The nutritional value of protein is mainly determined by its amino acid composition. There are twenty kinds of amino acids, eight of which are essential, and 12 can be transformed from other amino acids. Collagen contains a large number of non-essential amino acids, but the content of essential amino acids is relatively low, and it does not contain essential tryptophan at all. Therefore, as the source of protein, its contribution rate to the human body is actually very low. If it is the only source of protein in the diet, no matter how much you eat, it can't meet the needs of the human body.
