In a study, people with the highest
average intakes of carotenoid-rich vegetables — like sweet potatoes — and vitamin E-rich foods — like almonds — experienced a 47 percent reduced risk of moderate or greater hearing loss compared with the people who had the lowest average intakes of these nutrients.
And in another study from the same research team, people who ate a couple of servings per week of omega-3-rich fish — like salmon – experienced hearing protection as well.
After 2 years, the fish lovers had a 42 percent lower risk of developing age-related hearing loss compared with the participants who ate much less fish.
