In order to contribute to the recovery of neurasthenia patients, we believe that along with psychotherapy and medication, the diet and nutrition of patients should not be neglected. From what is known so far, the brain needs nutrients such as vitamins, calcium, phosphorus, potassium, magnesium and trace elements, in addition to lipids, proteins, sugars, oxygen and water. Therefore, patients with neurasthenia should pay special attention to the following foods that have nutritional value for the brain in terms of dietary therapy. 1, rich in lipid food: such as liver, fish, egg yolk, butter, soybeans, corn, sheep brain, pig brain, sesame oil, peanuts and walnuts, etc.. Lipids are important substances that make up brain tissue and are richer than other organs in the body, with lecithin being the most abundant. Take a lot of lecithin, can make the brain cell membranes become soft, and therefore conducive to the connection between the cells, can enhance memory, improve brain function, neurasthenia has a better effect. 2, protein-rich food: such as lean pork, mutton, beef, milk, chicken, duck, fish, eggs and soy products. Brain cells 35% by protein, in terms of its brain function, protein is the basis of the excitation and inhibition process of nerve cells in the brain, human sensory, memory, language, movement, etc. and the excitation and inhibition of nerve cells in the brain. 3, food rich in sugar: such as white sugar, brown sugar, honey, sugar cane, radish, rice, flour, sweet potatoes, dates, beets and fruits. Sugar is broken down into glucose in the body in order to pass the blood-brain barrier and be used by brain cells, which is the only source of energy for brain cells. 4, rich in vitamin B, vitamin PP (niacin and nicotinamide) and vitamin E food: such as yeast, liver, beans, peanuts, wheat, germ, brown rice, oats, corn, millet, sweet potatoes, cottonseed oil, cabbage and seaweed, etc.. Because vitamin B and vitamin PP is a coenzyme of the metabolism of the nervous system, it has a catalytic effect, which can strengthen the function of brain cells and promote the metabolic process of sugar and protein, thus promoting the excitation and inhibition of brain cells. Vitamin E is a powerful antioxidant that protects lecithin, an important component that makes up brain cells, from oxidative failure. However, it should be noted that vitamin E cannot be eaten with iron-containing foods such as celery, purple cabbage, spinach, liver and shellfish, otherwise it will fail. 5, rich in vitamin C food: general fruits and vegetables are rich in vitamin C. Some people say that vitamin C is the brain’s lubricant, because it is the brain to carry out the metabolic necessary substances. 6, rich in trace elements of food: such as animal liver, kidneys and oysters, coarse grains, soy products, fish, spinach, cabbage, etc.. American scholars Gossard has pointed out that students with good academic performance, the content of zinc and copper in their hair are higher, while the content of iodine, lead and pickaxe is lower. Canadian scholars have also reported similarly, they in children with mental deficiencies in the food mix of various trace elements content, and combined with behavioral treatment, after 2 years basically turned to normal.
