Healthy Diets Like Mediterranean Diet Linked with Lower Risk of Hearing Loss

Conversations, TVs at normal volume, and most social activities occur at mid-range frequency of sound. Therefore, mid-range hearing loss can make it difficult to communicate in day-to-day life. In this study, researchers followed 3,135 women who were an average of 59 years old and followed them for 3 years assessing their eating habits and hearing capability. Those most closely following a Mediterranean diet, a general healthy diet (as measured by the Alternate Healthy Eating Index), or a DASH Diet (a diet for healthy blood pressure that emphasizes fruits, vegetables, whole grains, and low-fat dairy) were 23-28%, 23-28%, and 25-29% less likely, respectively, to develop mid-range hearing loss than those not following those diets. The relationship with low-frequency and high-frequency hearing loss was not statistically significant.

Following a Mediterranean-Inspired Diet Linked with 30% Lower Risk of Hearing Loss in Women

Hearing loss is the third most common health problem in the US, so scientists wonder if there might be a relationship between diet and hearing over time. To test this relationship, researchers followed more than 81,000 women for 2 decades, tracking their eating patterns and health outcomes. Those most closely following a Mediterranean-inspired diet were 30% less likely to develop hearing loss over the 20-year study than those not following a Mediterranean diet. Similarly, people whose diets closely adhered to a DASH diet or the Alternative Healthy Eating Index (both of which also prioritize vegetables, fruits, and whole grains, and limit red meat and sweets), were also less likely to develop hearing loss over time.
