Tofu is a national dish of our country and is recognized as a good health care product. Because tofu is the best source of plant protein, it has the reputation of plant meat. It is worth noting that eating tofu should pay attention to scientific collocation in order to exert the greatest health care effect. The following small series will tell you several excellent collocation methods: Tofu with fish: Tofu contains protein lacking methionine and lysine, and tofu and fish are eaten together, which complement each other and have higher nutritional value. Tofu has a high calcium content, while fish is rich in vitamin D. When they are eaten together, the absorption rate of calcium can be improved many times. Therefore, it is especially suitable for middle-aged and elderly people, teenagers and pregnant women. Kelp tofu: Although saponin in tofu can promote fat metabolism and prevent arteriosclerosis, it is easy to cause iodine deficiency in human body. Kelp is rich in iodine, so it is very reasonable to use kelp as tofu. Radish tofu: Tofu is a plant protein. Eating too much will lead to indigestion. White radish can promote digestion. If mixed with tofu, it will be beneficial to the absorption of tofu. Tofu is rich in calcium, and white radish does not contain oxalic acid, which will not hinder the absorption of calcium. In addition, tofu with high nutrition is rich in protein, but it lacks a kind of methionine necessary for human body. If cooking alone, the utilization rate of protein is very low. If tofu is mixed with meat and eggs, the nutritional utilization rate of protein in tofu can be improved. Tofu is good in all aspects, but it is also taboo to eat. Tofu contains saponins, which can prevent atherosclerosis and promote the excretion of iodine in the body. Eating a lot of tofu for a long time is easy to cause iodine deficiency. In addition, eating too much tofu is easy to cause indigestion, and each meal should be around100g.
