The four favorite nutrients in the brain are:
1, lecithin-The human brain is composed of15 billion nerve cells. Excluding water, 43% of the dry matter is lecithin, which constitutes the cell membrane and axon myelin sheath of brain nerve cells. Lecithin is the most important basic structural substance of brain cells, so lecithin products are called "brain food".
2. DHA——DHA is a major component of the growth and maintenance of cells in the nervous system, and it is an important component of the brain and retina. It is as high as 20% in the human cerebral cortex and accounts for the largest proportion in the retina of the eyes, accounting for about 50%. Therefore, it is very important for the intellectual and visual development of the fetus. This is why pregnant women especially emphasize the need to supplement DHA.
3, healthy fat-most brain cell structures need healthy fat. The self-repair and renewal of the brain will consume a lot of omega-3 fatty acids.
4. Antioxidants-With the increase of age, free radicals flowing in the blood will decompose brain cells and eventually lead to memory loss. Antioxidants can fight the harm of free radicals, so eat more foods rich in antioxidants.
Therefore, fish is one of the first choice foods to promote intellectual development. Fish head is rich in lecithin, which is an important source of neurotransmitters in human brain. It can enhance people's memory, thinking and analytical ability, control the degeneration of brain cells and delay aging. Fish is also an excellent source of high-quality protein and calcium, especially containing a lot of unsaturated fatty acids, which is particularly important for the normal development of the brain and eyes.
