Tofu is not only natural and healthy, but it is also easy to make. It is a common dish we often eat. Tofu and all ingredients are almost "wild". However, if you want to better absorb the nutrition of tofu, you should find a good partner on the table. Soybean has the reputation of "plant meat" and it is the most excellent food for protein in plant foods. Soybeans made from soy do not have bad protein. However, the content and ratio of protein amino acids in tofu is not very reasonable and it is not particularly suitable for human digestion and absorption. Bloating, diarrhea and other symptoms. Increase the burden on the kidneys. Under normal circumstances, the plant protein that is eaten by humans is metabolized and eventually becomes nitrogenous waste, which is excreted by the kidneys. In the elderly, the ability of the kidneys to excrete waste is reduced. If you do not pay attention to your diet and eat large amounts of tofu at this time, excessive intake of plant proteins will inevitably increase the amount of nitrogen-containing waste generated in the body, increasing the burden on the kidneys and adversely affecting your health. Just like the need to supplement vitamin D at the same time to eat calcium tablets, to eat tofu to calcium, we must match some vitamin D-rich foods. Because of the absorption and utilization of calcium, vitamin D plays a very important role. Although tofu is rich in calcium, tofu has more calcium than the same amount of milk, but when eating tofu, foods rich in vitamin D content can be more effective. The egg yolk is rich in vitamin D, so the delicious and smooth egg yolk tofu is an excellent dish for calcium supplementation. Animal viscera, such as liver, blood vitamin D content is also high. Tofu not only supplements nutrition, but also has a certain therapeutic effect on preventing arteriosclerosis. This is because tofu contains a substance called saponin that prevents the production of oxidized lipids that cause arteriosclerosis. However, saponin can cause a trouble, causing abnormal iodine excretion in the body, which may lead to iodine deficiency if consumed for a long time. Therefore, when you eat tofu, add some kelp, seaweed, and other iodine-rich seafood to cook together, and you'll have the best of both worlds. Although tofu is rich in nutrients, there is a lack of dietary fiber and eating alone may cause constipation. Both vegetables and edible fungus are rich in dietary fiber, which can make up for this shortcoming of tofu. In addition, fungus and green vegetables also contain many antioxidants that can improve immunity and prevent diseases. When used with bean curd, they have better resistance to diseases. It should be noted that the content of oxalic acid in green leafy vegetables is relatively high.
