We've blogged in the past about how nutrition affects hearing, but now there's more! A study published in the May 11 issue of the Journal of Nutrition found that eating well contributes to a reduced risk of hearing loss among women. The study was conducted by Brigham and Women's Hospital in Boston and examined the relationship between hearing loss and three diets: The Alternate Mediterranean Diet (AMED), Dietary Approaches to Stop Hypertension (DASH), and the Alternative Healthy Eating Index-2010 (AHEI-2010).

Researchers followed 81,818 women for 22 years (1991-2013) and found that women who closely followed the AMED and DASH diets had about a 30 percent lower risk of moderate or worse hearing loss, compared to women who didn't follow these dietary guidelines. Additionally, a sub-cohort of 33,000 women who gave more detailed reports of hearing information as part of the study found that the amount of reduced risk of hearing loss could be greater than 30 percent and also relate to the AHEI-2010 diet.

The AMED diet features extra virgin olive oil, grains, legumes, vegetables, fruits, nuts, fish and moderate intake of alcohol. The DASH diet emphasizes fruits and vegetables, is moderate in dairy, meat, poultry and fish, and is low in fats, oils and sweets. The AHEI-2010 shares components of both of these diets. 

The authors of the study state that more research needs to be done, but that based on these findings they can conclude that, "Adherence to healthful dietary patterns is associated with lower risk of hearing loss in women, and consuming a healthy diet may be helpful in reducing the risk of acquired hearing loss."
