Age-related hearing loss is preventable

Age-related hearing loss, which affects a significant portion of the population, is commonly believed to be an inevitable consequence of growing old. However, research on rural populations in Africa and Asia has shown that maintaining a healthier lifestyle can prevent age-related hearing loss. Factors such as repeat exposure to loud noises, smoking, and ototoxic medications contribute to the premature death of sensory hair cells in the inner ear. Animal studies suggest that exposure to constant noise over 60 decibels can be harmful. Furthermore, diet plays a crucial role, as populations with healthier diets devoid of animal protein and rich in whole grains have been found to retain their hearing into old age. The Mabantra people, who follow a diet centered around whole grains and low in animal protein, demonstrate both excellent hearing and minimal risk of coronary artery disease. Atherosclerosis, clogging the small blood vessels in the inner ear, may be an underlying cause of age-related hearing loss in the rest of the world.
