Tofu has a high content of protein, which is comparable to high-quality animal protein such as eggs and milk in quality. Soybean protein can completely meet the needs of human body for various essential amino acids, and has the function of reducing the cholesterol content in blood. As long as you consume more than 25g of soy protein every day (equivalent to half a piece of tofu), you can reduce the cholesterol content in your blood and effectively prevent cardiovascular diseases. The main nutrition of tofu and soybean milk is no less than milk. The concentration of protein and calcium in tofu is even higher than that in milk, and the iron content is more than 10 ~ 20 times of that in milk. In particular, the absorption rate of calcium and iron in tofu is high, and soybean protein can reduce the excretion of calcium. Therefore, soybean food is a kind of health food, which has the functions of supplementing calcium and preventing osteoporosis, but it is much cheaper than milk. In addition, compared with eating meat and drinking milk, the cholesterol content of bean products such as tofu and soybean milk is almost zero, so many nutritionists call bean products the best healthy food with good quality and low price. Enzymatic hydrolysis of soybean protein can produce peptides with antioxidant, blood pressure lowering and immunity improving effects. Soybean peptide has the functions of lowering blood sugar, lowering blood pressure and preventing arteriosclerosis. For example, fermented soybean and fermented bean curd contain functional soybean peptides with high activity. For your health, please eat more than half a piece of tofu every day.
