Research suggests that eating a balanced and healthy diet is associated with lower risks of hearing loss. In addition to this, healthy dietary patterns also protect from cardiovascular diseases, inflammation, hypertension, diabetes, gastrointestinal problems and so on.
Hearing loss becomes more probable with age. There are a number of reasons for hearing loss. It can be due to some changes and damages to nerve going to the ear. Hearing loss can also be because of some disease or treatments harmful to the ear. High volume sounds are another well-known reason for hearing loss.
Researchers from Brigham and Women’s Hospital carried out this research. NIH’s Institute on Deafness and Other Communication Disorders and the National Cancer Institute supports this research. This research appears in the Journal of Nutrition.
Examining the effect of diet on hearing loss
Scientists studied the probability if diet also affects hearing. They examined questionnaires from seventy-one thousand women who took part in the research from 1991 to 2013. Researchers included the women who were 27 to 44 at the start of the study.
They selected non-Hispanic white women for the study. Researchers after every four years, through email, asked these women some questions about their dietary patterns. They also asked these women whether they observed any changes in their hearing as well.
The researchers also analyzed these answers to score the credibility of some known dietary patterns. They analyzed Alternate Mediterranean Diet (AMED), Dietary Approaches to Stop Hypertension (DASH) and the 2010 Alternative Healthy Eating Patterns (AHEI-2010).
They studied AMED diet consisting of grains, legumes, fish, vegetables, nuts, fruits, olive oil and consuming a small quantity of alcohol. Researchers analyzed the effects of DASH diet consisting fish, vegetables, fruits, lean meat and low amount of sodium intake. Furthermore, they also studied AHEI-2010 made up of fruits, vegetables, low sodium, whole grains and animal fats.
The good diet reduces the risk of hearing loss
Scientists found that out of seventy-one thousand women who took part in the study, 2306 women developed mild to severe hearing loss. Scientists found women consuming AMED and DASH diet or diet related to them had a 30% lower risk of hearing problems.
They also found that women with diet least related to DASH and AMED had more chances of hearing loss. They discovered women who didn’t follow these diet patterns were more prone to smoke and susceptible to high blood pressure. Scientists found many differences between the two groups and the latter was also less active and susceptible to other diseases.
The future insight
Scientists observed that following a healthy eating pattern throughout life reduces the risk of hearing loss. They observed that in addition to beneficial effects on hearing, eating well has many other significant effects on overall health.
