Increased intakes of folate and folic acid may reduce the risk of hearing loss in men by 20 per cent, according to researchers at the 2009 American Academy of Otolaryngology-Head and Neck Surgery Foundation (AAO-HNSF) Annual Meeting. Researchers led by Boston-based Josef Shargorodsky used the most recent figures from the Health Professionals Follow-up Study cohort from years 1986 to 2004, a group consisting of 51,529 male health professionals. The study identified 3,559 cases of men with hearing loss. When the nutritional data was analyzed, men over the age of 60 with high folate intake from foods and supplements had a 20 per cent decrease in risk of developing hearing loss.
In 2007 scientists from Wageningen University reported that folic acid supplements delayed age-related hearing loss in the low frequency region in a study of 728 men and women between the ages of 50 and 70 (Annals of Internal Medicine, Vol. 146, pp. 1-9). Another study, published earlier this year indicated a role for beta carotene and vitamins C and E, and the mineral magnesium in preventing prevent both temporary and permanent hearing loss in guinea pigs and mice.
