1.Limit the intake of fat. A large intake of fatty foods will increase blood lipids, increase blood viscosity and cause arteriosclerosis. The inner ear is most sensitive to blood supply disorders, and when blood circulation disorders occur, it will lead to a lack of nutrition of the auditory nerve, thus producing deafness. 2. Supplement protein and vitamin-rich foods. Research by experts found that noise can increase the consumption of some amino acids and vitamins in the human body. If the human body lacks vitamin foods, the hearing cells of the inner ear, which are responsible for the hearing function, will become degenerative; therefore, we should eat more foods rich in vitamin D, iron, zinc and other elements in our daily diet. These foods include lean meat, beans, fungus, mushrooms, green leafy vegetables, radish, tomatoes, garlic, oysters, etc. 3. Eat more foods containing zinc. There are many factors that cause senile deafness, and zinc deficiency is an important reason. Foods rich in zinc include: fish, beef, pork liver, chicken, chicken liver, eggs, various seafood; apples, oranges, walnuts, cucumbers, tomatoes, cabbage, radishes, etc. 4, drink more milk. Milk contains almost all known vitamins, such as vitamin A, vitamin D, vitamin B1, vitamin B2, vitamin B6, vitamin B12, vitamin E and carotene. These vitamins are helpful in the prevention and treatment of improved blood circulation and deafness symptoms, along with the absorption and utilization of calcium. 5. Patients with senile deafness can eat more fish food appropriately. Fish is rich in unsaturated fatty acids, which can make the neutral fat and cholesterol in the form of gel free from the walls of blood vessels to avoid the production of high blood lipids, so as to achieve the purpose of prevention and treatment of senile deafness. 6, often eat soy products. The content of iron and zinc in soybeans is much higher than other foods. The human body can supplement iron to expand microvessels, soften red blood cells and ensure the blood supply to the ear, which can effectively prevent hearing loss.
