There is no such thing as “the best food for desensitization”. Foods do not help desensitize. The best way to desensitize is to avoid allergens. Foods do not cure or prevent disease, and many foods are actually allergens themselves. Common allergens include: dairy, eggs, soy, fish, seafood, nuts, peanut products, and more. All foods containing heterogeneous proteins can be allergic, but the probability of allergy varies from one group of people to another. The best way to desensitize is to avoid the allergen. Allergen avoidance needs to be continued for 3-6 months. If symptoms improve significantly, children over one year of age can be retested for allergens, and if the results are favorable, they can be monitored by a physician and ingested in small amounts to observe the reaction. Allergies are a highly prevalent group of illnesses. When they occur, seek medical attention and treat them aggressively under a doctor’s supervision.
