An elimination diet, sometimes called exclusion diet or allergy avoidance diet is a diet in which likely allergens or other foods that people may be sensitive to are avoided. This diet is used to identify those foods that an individual is sensitive to through first exclusion and then challenges. An elimination diet functions as a test and while on this diet, it is important to keep a food diary.
Nasal lavage is a method of cleansing the nasal passages. It is useful for anyone who suffers from chronic sinus infections, allergies, or hay fever. Nasal lavage flushes and cleanses the nasal passages, thus removing the source of infection. The liquid used is a mild solution of water, salt, and baking soda. The water flushes the nasal passage, the salt kills bacteria and provides some drying to help reduce the mucous membrane swelling.
