The treasure of natural soybean protein powder, imported from the United States, in which the main component soybean protein is selected from high-quality pollution-free soybean raw materials; It is refined by separation and extraction. The content of protein is as high as 85%, and the proportion of amino acids is closer to human needs. So, what is the role of soybean protein in the natural treasure soybean protein powder? The main functions of soybean protein in natural treasure soybean protein powder are: 1. For dieters who need a low-calorie diet, replacing part of protein with soy protein can not only reduce the intake of cholesterol and saturated fat, but also achieve a balanced nutritional intake. 2. Soy protein isolate is a perfect high-quality protein supplement for vegetarians and ordinary people. 3. Soy protein can prevent urinary calcium loss, promote bone health and reduce the chance of osteoporosis. 4. Studies show that the intake of 25g soy protein every day can effectively reduce the contents of total cholesterol and low-density lipoprotein cholesterol in human blood, thus reducing the risk of heart disease. Effect of soybean protein on human plasma cholesterol and its mechanism: Results: (1) Compared with the beginning of the experiment, the plasma cholesterol concentration in casein group increased significantly, but there was no significant increase in soybean protein group and casein calcium group. (2) Compared with casein group, the excretion of calcium, phosphorus and magnesium in feces of soybean protein group increased significantly; Fecal fat and bile acid excretion increased by 33.6% and 45.3% respectively. (3) Fecal bile acid excretion was positively correlated with fecal calcium, phosphorus, magnesium and fat excretion. Plasma cholesterol concentration decreased with the increase of bile acid excretion in feces. It can be seen that the mechanism of soybean protein reducing plasma cholesterol concentration may be due to the increase of bile acid excretion in feces, which leads to the increase of cholesterol synthesis in liver, thus reducing plasma cholesterol concentration.
