The food containing more protein is beans, among which soybean has the most content, broad bean is in the middle, followed by mung bean. Science shows that drinking 200ml of soybean milk can get about 8.8g of protein, which is higher than some milk and milk powder on the market, but the price is relatively low. Eating beans in moderation can effectively supplement the daily protein. As a by-product of soybean milk, tofu also contains more protein. There is a popular saying that "it is better to eat meat than tofu", because tofu contains more protein, even more than pork, and contains almost no fat, which is especially suitable for ladies who love beauty.
