The Dietary Skills Prevent Presbycusis
Because of the decreasing physical functions and microcirculatory disturbance of cochlea, when people become old, the hearing ability will be gradually decreased, which is called "presbycusis". If people pay attention to the dietary arrangement in daily life, the presbycusis can be effectively alleviated and even prevented. Four dietary skills will be introduced for people to follow in daily life. First, people should reasonably control the intake amount of food to prolong the life. The experts have studied the relationship between limited diet, long life and presbycusis. According to the research result, to control the diet can probably defer the occurrence deafness. Second, people should supplement adequate iron. When people become old, the capillaries in the ears and the red cells will become hard. The hard red cells can easily block the capillaries to cause the microcirculatory disturbance, which can stop the supply of oxygen and nutrients for the hair cells and cause presbycusis. The adequate supplementation of iron can expand the capillaries, soften the red cells and maintain the normal supply of blood so as to effectively prevent the formation of decreasing hearing. Therefore, people should often eat the foods containing abundant iron, such as lean meat, animal liver and spinach. Third, people should increase the intake of the foods containing zinc and vitamin D. according to the research, the content of zinc inside the cochlea is rather high. When people become more than 60 years old, the content of zinc will be obviously decreased, which can affect the functions of cochlea and hurt the hearing. Therefore, it is necessary for people to supplement zinc. At the same time, the formation of deafness keeps a close relationship with the exceptional metabolism of vitamin D inside the human body. When vitamin D is lacked, the content of blood serum calcium inside the human body is lower than the normal level, which can cause deafness. In order to prevent the illness, people should absorb enough zinc and vitamin D in daily life. The foods like lean meat and mushroom all contain abundant nutrients. Fourth, people should decrease the blood fat in daily life. The high blood fat can affect the blood circulation and increase the peroxides in the inner ears. Therefore, it is necessary for the aged to decrease the blood fat so as to prevent the presbycusis. The blood fat can be decreased by eating the foods like onion, corn, cucumber and kelp.
