Choose a good pot when cooking, or add more vinegar when cooking. There are also some foods that can supplement iron. Such as animal liver, duck blood, pig blood and some other meat. There are some green vegetables, black fungus, black rice and other melanin foods.

There is a misunderstanding that iron can be supplemented indirectly when cooking in an iron pan, which is made of iron, and the idea that iron can be supplemented when cooking in an iron pan has always been rooted in people's hearts. Iron pots contain iron as a mineral, and iron also exists in our bodies. So when we cook in an iron pan, iron ions will melt into food, and when people eat, they will indirectly supplement iron.

most people agree with this explanation, but in the process of scientific progress and the study of trace elements in human body, the medical profession found that the iron pot is actually a big misunderstanding. At the same time, the medical profession has also confirmed the mistakes in our daily life.

Because the iron in the wok is oxidized to trivalent iron when you cook. What the body needs is bivalent iron. Trivalent iron is not easily absorbed by the human body, and it is toxic and will cause harm to the human body. In addition to iron supplementation in iron pots, there are other misunderstandings in our daily life, such as iron supplementation in spinach, which is actually a misunderstanding. In fact, today's research shows that spinach is not rich in iron, and spinach contains oxalic acid, which easily reacts with iron to form a precipitate, so that iron cannot be used in the human body.

In order to effectively supplement iron, we must first have a specific understanding of iron diet. Heme iron mainly exists in red meat and liver of animals, and is easily absorbed by human body, and is not affected by other food components. Non-heme iron mainly exists in plants and is not easily absorbed.

For iron supplementation, we mainly use heme iron, and animal red meat and liver are the best products for iron supplementation. Natural animal meat should not be eaten more, because too much protein and fat are harmful to health.
