Protein has the highest content in the brain. Brain cells need a lot of protein to supplement and update during metabolism. Experiments show that eating different contents of protein food has a significant effect on brain activity. Increasing the content of protein in food can enhance the excitability and inhibition of cerebral cortex, and the synthetic acid in protein can also eliminate the toxicity of ammonia produced by brain cells in metabolism, thus protecting the brain.
Food suitable for mental workers:
1. Foods rich in carbohydrates: such as rice, flour, millet, corn, red dates, longan and honey.
2. Foods rich in high-quality protein, such as eggs, milk, fish, poultry, lean meat and soybeans.
3. Foods rich in unsaturated fatty acids: such as vegetable oil, sunflower seeds, pumpkin seeds, peanuts, watermelon seeds, walnuts, fish and shrimp.
4. Foods rich in cephalin: such as pig brain, sheep brain and chicken brain. Foods rich in lecithin mainly exist in egg yolk, duck egg yolk, quail egg yolk, soybean and its products.
5. Foods rich in vitamin A: such as animal liver, milk, eggs and carrots, leeks, kelp and fungus.
6. Foods rich in B vitamins: cereals, beans, peanuts, walnuts, sesame seeds, mushrooms, vegetables, eggs, milk, lean pork, viscera, yeast, eels, etc.
7. Foods rich in vitamin C: fresh dates, kiwis, oranges, lemons, grapefruit, cauliflower, green leafy vegetables, peppers, tomatoes, etc.
The lipids needed by the human brain are mainly cephalin and lecithin (which contain unsaturated fatty acids). They have the function of nourishing the brain, making people full of energy, enhancing the endurance of work and study, and have a good effect on neurasthenia. In addition, scientists have found that when people engage in high-intensity mental work for a long time, the body may have lipid metabolism disorder, which will increase the serum cholesterol content and cause hyperlipidemia and obesity. Nerve activity will also increase the body's demand for vitamin C, nicotinic acid, B vitamins and vitamins. In a word, the nutrition of mental workers should focus on supplementing the energy of brain tissue activities, phospholipids or unsaturated fatty acids that constitute brain cells, protein, vitamin A and trace elements that participate in regulating the excitement or inhibition of brain cells. For mental workers with less auxiliary activities, especially those over middle age, due to their low intake of heat energy, special attention should be paid to ensuring adequate intake of high-quality protein and vitamins, reducing the intake of pure sugar and pure fat food, increasing the intake of vegetables and fruits, and scientifically arranging three meals a day.
