Did you know that nutrition has an affect on your hearing? Studies have shown that a deficiency in nutrients, such as B12 and folic acid, can impair hearing by as much as 39%, while increasing these nutrients can protect hearing by as much as 20%. Folic acid deficiency specifically has been linked with high-frequency hearing loss. In addition to folic acid and vitamin B12, a deficiency in potassium, magnesium, and zinc and omega 3’s can also have a negative impact on your hearing. A healthy diet can also be an important source of antioxidants, which help protect against damage from oxidative stress, which can lead to cell damage.
