Food allergies can result in life-threatening reactions and diminish quality of life. In the last several decades, the prevalence of food allergies has increased.

Treatment of food allergy involves strict avoidance of the trigger food.
Medications, such as epineprine, manage symptoms of disease, but currently, there is no cure for food allergy. OIT and herbal formula trials are ongoing but there is no conclusive evidence of sustained benefit yet.
