Nerve is like an elastic rubber band, which can be stretched and shortened at will under control. However, if the rubber band is stretched continuously, it will lose its elasticity and will never stretch or shrink again. Therefore, all kinds of discomfort caused by nerve failure should also start with regulating nerves. Specifically, it is to cultivate spirit around all aspects of daily life. It is very necessary for neurasthenia patients to pay attention to supplementing nutrients necessary for the brain through diet conditioning. Patients with neurasthenia should pay special attention to the following foods with nutritional value to the brain in diet conditioning. [Dietary principles] 1. Eat more foods rich in lipids. Lecithin in lipids can soften the membrane of brain cells, which is beneficial to the connection between cells, enhance memory and improve brain function, and has a good effect on neurasthenia. 2. Eat a high-protein diet. Protein is the basis of the exciting and inhibiting process of brain nerve cells. People's feelings, memories, language and actions are all related to the exciting and inhibiting process of brain nerve cells. 3. Eat foods rich in sugar. Sugar is decomposed into glucose in the body, which is the main energy source of brain cells. 4. Eat foods containing B vitamins, E vitamins and P vitamins. [beneficial food] 1. Foods rich in lipids: such as liver, fish, egg yolk, butter, soybean, corn, sheep brain, pig brain, sesame oil, peanuts, walnuts, etc. 2. Foods rich in protein: such as lean pork, mutton, beef, milk, chickens and ducks, fish, eggs and bean products. 3. Foods rich in sugar: such as white sugar, brown sugar, honey, sugarcane, radish, rice, flour, sweet potato, jujube, beet, fruit, etc. 4. Yeast, beans, peanuts, wheat, germ, brown rice, oats, millet, sweet potato, cottonseed oil, Chinese cabbage and seaweed should also be taken in moderation.
