How could diet affect allergic rhinitis?

One of the risk factors for developing allergic rhinitis later in life is having a food allergy during early childhood (<2 years old).^[1] It is believed that introducing foods associated with allergy (e.g., peanuts, gluten, eggs, dairy, and shellfish) to infants may reduce the risk of developing food allergies, and ergo allergic rhinitis later in life. However, the evidence surrounding early allergenic food introduction and developing allergic rhinitis is weak. Currently, there are no dietary recommendations for improving allergic rhinitis. ^[2]
