* Presenting author
Considering growing cities and portable audio devices, increasingly people have deviations in the threshold of hearing. Thus, hearing loss is a point of concern in modern society, being one of the most common causes of disability. Furthermore, it may cause social isolation, dependence, cognitive impairment among several other undesired effects that certainly limits the quality of life of individuals. The prevalent origin of hearing loss is sensorineural, caused by irreversible loss of hearing cells (hair cells in the organ of Corti and/or spiral ganglion neurons). Sensorineural hearing loss has a multifactorial etiology including genetic and environmental factors such as exposure to high levels of noise, pathologies, ototoxic substances, nutritional deficiencies and aging. Some recent studies have been shown a correlation between hearing loss and certain nutrients (such as folic acid and omega-3 fatty acids). This work focuses on the nutritional aspects detected in hearing loss studied thus far, and suggests that an adequate diet on specific nutrients may increase prevention of hearing loss.
