News - Antioxidants reduce hearing loss risk

By Nutri People

New research from scientists at the University of Sydney reports that vitamins A and E may significantly reduce the risk of hearing loss. The findings, published in the Journal of Nutrition, Health & Aging, show that people with the highest average intakes of vitamin A and vitamin E had significantly lower risks of hearing loss compared to people with the lowest average intakes.

The researchers, led by Professor Paul Mitchell, unearthed these findings when they analysed food frequency data from 2,956 people participating in the Blue Mountains Hearing Study. The results showed that, over five years of study, people with the highest average intakes of vitamin A had a 47% reduced risk of moderate or greater hearing loss, while increasing dietary vitamin E intakes were linked with a 14% reduction in hearing loss.

Commenting on the mechanism, the authors of the study note that reactive oxygen species may damage the inner portion of the ear associated with hearing, and therefore, antioxidants may counter this damage and reduce age-related hearing loss. They are now calling for further research to confirm their findings.
