Tofu is a very traditional food in my country. According to legend, it was invented by Liu An, King of Huainan in the Han Dynasty. However, some people say that tofu was invented by Guan Yu and Le Yi. Many people have their own opinions on this. But it is worthy of recognition that our people love tofu very much. Due to their love for tofu, tofu has also been made into various delicacies. However, there are the following points that need to be noted:

1 .Tofu cannot be eaten at the same time as spinach and other vegetables with high oxalic acid content

Spinach is rich in nutrients and is called the "King of Vegetables". There is also a saying on the Internet: Popeye, love it. Spinach? It can be seen that spinach is very beneficial to the human body. People who eat spinach regularly are helpful to their health and body shape. Spinach contains a lot of oxalic acid, about 300 mg of oxalic acid per 100 grams of spinach, while tofu contains more calcium. If both enter the human body at the same time, they can undergo chemical changes in the human body to generate insoluble calcium oxalate. Stones in the human body are formed by the deposition of insoluble calcium salts such as calcium oxalate and calcium carbonate, so do not cook these two foods together. In mild cases, you may suffer from stomach pain, and in severe cases, you may be poisoned.

2. Although tofu is nutritious, some people are not suitable for eating it

Tofu contains a lot of purine. It should not be used by gout patients with purine metabolism disorders and patients with increased blood uric acid concentration. When eating tofu, people with weak spleen and stomach and poor digestion should also eat less tofu. Because a lot of tofu on the market today is made with gypsum added. In the past, the workmanship of brine tofu was complicated and few people made it. If you consume too much tofu, it will increase the burden on the gastrointestinal tract and the kidneys, which will impair kidney function. Further decline is detrimental to health.

3. Excessive consumption of tofu can lead to iodine deficiency

Tofu is made from soybeans. Soybean seeds contain a substance called saponin, which can not only prevent arteriosclerosis , and can also promote the excretion of iodine in the human body. Therefore, long-term excessive consumption of tofu can easily cause iodine deficiency, leading to iodine deficiency disease.

So although tofu is good, it must be eaten in moderation. It has advantages and disadvantages. ?
