Rising hearing threshold is a relatively common type of disease that affects people who are mainly engaged in noisy jobs, but in fact, anyone can suffer from rising hearing threshold. Therefore, we should do our best to prevent it, but there are still many people who suffer from it. So, what should be done to prevent deafness with a rising hearing threshold diet? The following is a brief introduction: 1. To limit the intake of fat: a large intake of fatty foods will increase blood lipids, increase blood viscosity and cause atherosclerosis. 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, which will produce a rise in hearing threshold. Therefore, the total daily fat intake for the elderly should be controlled at approximately 40 grams, and lipid-rich foods such as various animal offal, fatty meat, cream, egg yolk, fish roe, and fried foods should be eaten sparingly. The total daily cholesterol content in food should be below 300 mg. Eat less animal fat and cholesterol-rich foods such as egg yolk, animal offal, prawns, cream, etc. Cooking methods should be stewed and boiled as much as possible, avoiding deep-frying and pan-frying. 2, more protein-rich and vitamin-rich food: research by experts found that noise can make the human body in some amino acids and vitamins (such as vitamin B1, B2, B6, etc.) consumption increased. The human body lacks vitamin food, especially when lacking vitamin D, its metabolic derivative calcitriol decreases, and the inner ear auditory cells of the hearing function will undergo degenerative lesions; at the same time, vitamin deficiency can cause an increase in red fine hardness, which is difficult to pass through the terminal microvessels, leading to a lack of oxygen and zinc in auditory cells, which is also related to the rising hearing threshold in old age. Therefore, we should eat more foods rich in vitamin D, iron, zinc and other elements in our daily diet. Such foods are mainly lean meat, beans, fungus, mushrooms, various green leafy vegetables, radish, tomatoes, garlic, oysters, etc. 3, eat more zinc-containing food: there are many factors that lead to the rise of the hearing threshold in old age, and zinc deficiency is an important reason. Zinc is one of the 14 essential trace elements in the human body, so it is called the “life element”. The amount of zinc in the cochlea is much higher than in other organs. The zinc content in the cochlea is significantly lower in elderly people over 60 years old, which affects the function of the cochlea and leads to hearing loss. Research data from British scholars show that the zinc concentration in the serum is low in 1/3 of patients with increased hearing thresholds. After 3-6 months of zinc supplementation, about 30% of the patients’ hearing improves (no interruptions in listening). 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: some people say that milk is “human nanny”, after the 60s the world’s milk production and consumption has increased dramatically. Milk is a nutritious food, but also the best longevity food for the elderly. It has a high absorption rate and high utilization rate, and is a nutritious health food that is both economical and safe. The minerals in milk are mainly alkaline elements, so milk is an alkaline food, which has the effect of regulating the acid-base balance of the body. A stable environment in the body is the basis of disease prevention and resistance, as well as anti-fatigue and delayed aging. In addition, milk contains almost all known vitamins to vitamin A, vitamin D, vitamin B1, vitamin B2, vitamin B6, vitamin B12, vitamin E and carotene. In summer, milk is especially high in vitamins A, D and B2. The absorption and utilization of these vitamins with calcium are useful in the prevention and treatment of symptoms of improved blood circulation and rising hearing threshold.
