The ear, nose, and throat are all interconnected parts of the body and control the functions of balance, smelling, speech, swallowing, and hearing. The ears are connected to the throat through a passageway called the Eustachian tubes, which balance air pressure and drain fluid internally from the ear. The nose is directly connected to the throat (referred to as the pharynx) to help with breathing. Conditions such as allergic rhinitis, tinnitus, vertigo, and throat infections can affect ear, nose, and throat health.

Anecdotally, some people have reported improvements in various conditions involving the ear, nose, and throat after dietary changes. Although there is some evidence to suggest there is an association between dietary interventions and a reduced risk of hearing problems^[1] and allergic rhinitis,^[2] further research is needed to determine specific dietary recommendations.

Notable supplements that may help with allergic rhinitis include probiotics,^[3] pelargonium sidoides, and spirulina. vitamin c,^[4] zinc,^[5] and probiotics^[6] may be helpful for treating or preventing upper respiratory infections. melatonin may provide benefits in the context of tinnitus.
