Seniors who consume optimal amounts of vitamin C also have the best hearing, according to a study from Yonsei University College of Medicine in Seoul, South Korea. Hearing tests were compared to vitamin intakes in 1,910 participants in the 2011 Korea National Health and Nutrition Examination Survey. Results showed that seniors who consumed the most vitamin C also performed the best on hearing tests. As dietary supplement use of vitamin C increased so did hearing scores at all frequencies. Optimal intakes of vitamins A, B2, and niacin also appeared to improve hearing in seniors, while vitamin D had an inverse relationship to hearing ability. The researchers conclude that, “…we should consider proper diet counseling to prevent hearing decline.”
