Four perfect nutrients for eating tofu: 1. Adding kelp and laver can supplement iodine. Tofu can not only supplement nutrition, but also has a certain therapeutic effect on preventing arteriosclerosis. This is because tofu contains a substance called saponin, which can prevent the production of oxidized lipids that cause arteriosclerosis. But saponin will bring a trouble: it will cause iodine excretion in the body, and long-term consumption may lead to iodine deficiency. Therefore, when eating tofu, add some iodine-rich seafood such as kelp and laver to cook together, and you will have the best of both worlds. 2, add egg yolk, blood tofu, calcium supplements. Just like eating calcium tablets and supplementing vitamin D, tofu should also supplement some foods rich in vitamin D, because vitamin D plays a very important role in the absorption and utilization of calcium. Although the calcium content of tofu is very rich, the calcium in north tofu is more than the same amount of milk, but when eating tofu, it can be more synergistic with foods rich in vitamin D. Egg yolk is rich in vitamin D, so delicious and tender egg yolk tofu is an excellent dish for calcium supplementation. The content of vitamin D in animal viscera such as liver and blood is also high, so it is also very ideal to make white tofu and blood tofu into "red and white tofu". In addition, the internal organs of animals such as chicken gizzards and pig livers also have a good effect on increasing the calcium absorption of tofu. 3, with some meat, protein is easy to absorb. Soybean has the reputation of "plant meat" and is the best food in protein. Tofu made from soybeans is certainly not bad in protein. However, the content and proportion of protein amino acids in tofu is not very reasonable, and it is not particularly suitable for human digestion and absorption. Therefore, if you add some very high-quality food from protein while eating tofu, it can play a complementary role with tofu as protein, so that the protein of tofu can be better absorbed and utilized by the human body. And these high-quality protein foods are meat and eggs. Therefore, tofu mixed with minced meat and preserved eggs can make the protein of tofu better absorbed. 4. Put more vegetables and fungus to prevent diseases. Although tofu is rich in nutrition, it lacks dietary fiber. Eating tofu alone may cause constipation. Vegetables and fungus are rich in dietary fiber, which can just make up for this shortcoming of tofu. In addition, auricularia auricula and green vegetables also contain many antioxidant components, which can improve immunity and prevent diseases. Eat with tofu, they have stronger disease resistance. It should be noted that spinach, amaranth and other green leafy vegetables have high oxalic acid content, so they should be cooked with tofu first to avoid affecting the absorption of calcium in tofu.
