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.
