Food allergies. What is his symptoms? Make sure it is not food intolerance especially spicy food which often causes stomach upset or worsening or his reflux symptoms. There are currently no treatment for food allergies except in some centers where studies are being done. However for food intolerance symptoms, he can get mediations to improve his symptoms depending what it is.
