Eat more foods rich in iron: iron deficiency can easily harden red blood cells and reduce the ability to transport oxygen. Insufficient nutrition supply in the ear will damage the function of hearing cells and lead to hearing loss. Iron supplementation can effectively prevent and delay the occurrence of tinnitus and deafness in the elderly. According to the iron demand standards of different age groups in China, the daily iron intake of people over 45 years old, regardless of gender, should be no less than 12 mg. Porphyra contains more iron per hundred grams, including shrimp skin 16.5 mg, jellyfish skin 17.6 mg, black sesame seed 26.3 mg, day lily 12.6 mg, auricularia auricula1.9 mg and amaranth/kloc-0.

Supplementing foods rich in zinc: The synthesis of zinc, nucleic acid and protein is closely related to the metabolism of carbohydrates and vitamin A, and the content of zinc in blood and myocardium of patients with hypertension and atherosclerosis decreases. Pregnant women are short of zinc, and the fetus may have congenital malformation of the central nervous system. Studies have shown that 1/3 of the elderly with tinnitus and deafness have different degrees of zinc deficiency. Adults can maintain a balance by taking15mg of zinc every day. The foods containing the most zinc are oysters, liver, coarse grains, dried beans, nuts, eggs, meat and fish, and the zinc content in milk is much less than that in meat.

Eat more vegetables and hard nuts rich in vitamins C and E: Vitamins C and E can improve the function of superoxide dismutase, improve the utilization rate of oxygen, improve peripheral blood flow and protect the inner ear. Fresh green leafy vegetables contain more vitamin C, while black sesame, vegetable oil, walnut and peanut contain more vitamin E. ..

Appropriate intake of foods containing more vitamin D: Vitamin D can promote the absorption and utilization of calcium. A survey in the United States found that people with senile deafness have symptoms of low blood calcium, which is related to vitamin D deficiency. Animal liver, eggs, mushrooms, tremella and so on contain more vitamin D.

Eat more foods that can promote blood circulation: promoting blood circulation and removing blood stasis can dilate blood vessels, improve blood viscosity, and help maintain the normal microcirculation of small blood vessels in the ear. You can often eat black fungus, leek, red wine, yellow wine and so on.

In addition, we should also pay attention to eating less sweet, salty, cholesterol-rich and cellulose-poor foods: these foods can lead to hypertension, arteriosclerosis and diabetes, which can promote vascular diseases in the inner ear and accelerate the progress of tinnitus and deafness.
