As people age, their hearing gradually declines, and in some cases, it may deteriorate from weakness to deafness. This is a normal physiological phenomenon. However, the onset of hearing loss is related to individual factors such as genetics, lifestyle habits, dietary preferences, and physical condition. Frequently consuming high-fat foods can often lead to premature age-related hearing loss.
The inner ear's cochlea contains numerous hair cells that detect vibrations from sound waves, enabling us to hear. These hair cells are supplied with blood by the micro-vessels branching from the brain's vertebral-basilar artery. If the blood supply is interrupted, the hair cells will die, resulting in hearing loss. The micro-vessels in the ear are very small. A long-term high-fat diet can elevate blood lipids. These lipids not only deposit on the vessel walls, narrowing the micro-vessels, but can also easily block them, leading to insufficient blood supply. This can cause microcirculation disorders, completely cutting off the blood supply and nutrition to the auditory receptors, and may also result in sudden deafness. It can also be said that hearing loss is a precursor to hyperlipoproteinemia, coronary heart disease, and arteriosclerosis in the elderly, as it can appear six months to a year before other symptoms.
To prevent the premature onset of age-related hearing loss, reducing the intake of high-fat foods should be the primary measure. The elderly should consume less fatty meat, egg yolks, and sesame seeds. Cooking should be light, using less animal oil. Instead, they can choose easily digestible fresh vegetables, lean meat, and soy products. It is also advisable to eat more fruits and to quit smoking and alcohol. Furthermore, supplementing with certain nutrients that are essential but often deficient, and beneficial for lowering blood lipids—such as omega-3 polyunsaturated fatty acids, egg yolk lecithin, and vitamins B1 and E—can also help delay age-related hearing loss.
Bolile Nutritional Granules, developed by Wanboli Company of China Agricultural University using the bioreactor technology from a national "9th Five-Year Plan" science and technology research project, has an optimized combination of the aforementioned nutrients, enhancing their biological activity. It has a high biological value and an absorption and utilization rate in the human body of over 96%. It has a significant effect on lowering blood lipids, effectively reducing triglyceride and cholesterol levels in the blood, and decreasing blood viscosity. It helps prevent and treat arteriosclerosis and coronary heart disease, delays aging, improves memory, and combats fatigue. It also plays a certain role in delaying age-related hearing loss that may be caused by high blood lipids.
