老年性耳聋的患病率在65岁以上的人中高达30-50％。究其原因,与耳部微血管退化、耳蜗病变以及全身机能退化密切相关。有关专家指出,如果能尽早注意饮食调节,可以有效地预防老年性耳聋的发生。医学专家研究发现,补充铁质可以扩张微血管,软化红血球,保证耳部血液供应,能有效防止听力减退。又因耳蜗内锌含量大大高于其他器官,而人进入老年后耳蜗内锌含量会明显降低而导致听力减退,故须补锌。含锌丰富的食物有大豆及豆制品、鱼类、萝卜及海产品等。另外,美国学者研究发现,补充维生素D可防耳聋。
The prevalence of senile dementia is as high as 30-50% in people over the age of 65. The reason, and ear microvascular degeneration, cochlear lesions and systemic function is closely related to degeneration. Experts pointed out that if we can pay attention to diet regulation as soon as possible, can effectively prevent the occurrence of senile deafness. Medical experts found that iron supplementation can dilate microvessels, soften red blood cells, ensure the ear blood supply, can effectively prevent hearing loss. Because of zinc content in the cochlea is much higher than other organs, and people into the elderly after the zinc content in the cochlea will be significantly reduced leading to hearing loss, it is necessary to zinc. Zinc-rich foods are soybeans and soy products, fish, radish and seafood. In addition, the United States scholars found that vitamin D supplementation can prevent deafness.
