Benefits of eating fish regularly:
1 Eating fish will make people smart. Fish is rich in DHA, which mainly exists in brain, retina and nerve. DHA can not only maintain the normal function of human retina, but also benefit the development of human intelligence system. Long-term follow-up study found that the gray matter volume of hippocampus, anterior cuneiform lobe, posterior cingulate gyrus and orbitofrontal cortex increased significantly in elderly people with normal cognitive function who enjoyed fried fish or grilled fish every week.
2. Eating fish contributes to human development. Fish is rich in protein, and the content of protein in every 500g of fish is equivalent to the content of protein in 600g of eggs or 850g of pork.
Rich protein is the carrier of human life, which has the functions of balancing nutrition, regulating water balance in the body, improving immunity and so on, and can effectively help the growth and development of infants, children and adolescents. This is also one of the reasons why we eat fish when we are sick or have a wound, because fish can also help the wound to recover and heal.
3. Eating fish often can lower cholesterol. Most of the fats contained in fish are unsaturated fatty acids, which are easily digested and absorbed by human body. The digested and absorbed fatty acids can combine with blood cholesterol in the blood, taking cholesterol away from blood vessels, thus reducing the cholesterol content in the body and being beneficial to health.
4, eating fish has a good effect of lowering blood fat. Eating fish often can reduce blood fat. Medical experiments have proved that under the same blood lipid level, people who eat fish after a period of time can continuously lower their blood lipid levels compared with those who don't eat fish often, and the difference between them is 40%.
