But some things seem taboo, such as chicken feet that many people like to chew now. When I was a child, I was strictly forbidden to eat them. The older generation said that children can't write well when they eat chicken feet (chickens like to scratch the ground with their claws); Fish eggs are also among the fasting. I don't remember the specific reason.
When I grew up, I learned some scientific knowledge, and gradually realized that the original theories about eating, such as "what you eat supplements what you eat" and "shaping by shape", were mostly the dregs of culture, unreasonable and even harmful. For example, taking bone marrow and drinking bone soup can not only supplement bone and calcium, but also make people obese; There are no more substances beneficial to wisdom or appearance in pig brain and pig skin, and it is easy to suffer from hyperlipidemia if you eat too much. "Form filling" is more often just a psychological suggestion, which satisfies our appetite and makes us feel good at the same time.
Eat brain to replenish brain? The pig disagreed.
Recently, I read some articles criticizing "what you eat supplements what you eat", which is roughly the above example. However, it is not advisable to deny the traditional diet theory and sweep it into the garbage.
Because from a scientific point of view, it is not all wrong to eat what you supplement, and "enriching blood" is one of them.
Anemia is a problem for many people.
Many people suffer from anemia. According to statistics, there are about 654.38+0.5 billion people in the world, among which women and children are the most common. In 2065.438+05 alone, 54,000 people died of iron deficiency anemia, which is a huge number.
How is anemia caused? It is not that there is less blood in our body, but that the number of red blood cells in the blood has dropped greatly, which leads to the weakening of the oxygen carrying capacity of blood and the lack of oxygen supply to the brain and other organs of the body. When anemia occurs, people will feel tired, dizzy, headache, weakness, decreased exercise endurance and pale face.

There are many kinds of anemia, among which iron deficiency anemia is mainly caused by iron deficiency in human body.
You may ask, iron is the second most abundant element in the earth's crust, and it is not scarce. Why do we lack iron in our bodies?
You're right. Iron is high in nature, but not much in our body. All the iron in an adult's body usually does not exceed 5 grams, and no nail weighs. Therefore, the ancients said that "you are covered in iron and can't hit a nail" is also reasonable.
