Do food allergies go away?

Yes. Yes, particularly in children. Most children with allergy to milk, egg and soy outgrow their allergies by age 5-6. However, childhood peanut allergy can be lifelong. In adults it is a different story. Their allergies will be lifelong once they develop it; most commonly they develop allergies to shellfish which stays on for life.
Depends. I agree with the above answers. Most food allergies including egg, milk, soy, and wheat allergy resolve over time. However, some studies suggest that some children are outgrowing them later in childhood than previously thought. Only about 20% of children outgrow peanut allergy. Peanut, treenut, and shellfish allergy are present through adulthood and require lifelong avoidance.
Yes. Especially in kids. Food allergies to cow's milk, egg, wheat, soy, and corn that begin in infancy or early childhood usually resolve by adolescence and often by kindergarten entry. Unfortunately peanut, tree nut, and crustacean allergy is more likely to persist whether starting in childhood or adulthood. Only 20-25% of children allergic to peanut or tree nuts ever tolerate these foods in life.

Do food allergies go away if keep eating same food over and over in small amount?

Possibly. It is like desensitizing if you start very slowly with small amounts and prepress slowly . It is like allergy shots for desensitization. Read more...
Not exactly. Be careful. There are currently no fda-approved protocols for oral desensitization to any food. This is still an experimental topic and i would not suggest that you attempt such a procedure. Read more...
No. Repeatedly stimulating the immune system with small amounts of food just keeps the reactivity going, unless it's done under an allergist's supervision as a desensitization diet. Most children outgrow food allergies (except peanut and shrimp) by strictly eliminating them from the diet for 2-5 years. Adults still allergic to foods are typically stuck with their food allergies for life. Read more...
Unfortunately, no. If you have a true food allergy (not just intolerance) & you keep eating the allergenic foods, you'll stay allergic to them (the rare exception would be doing desensitization while supervised by an allergist). Kids may outgrow some of their food allergies if they avoid those foods for a few years, but most adults are stuck with their food allergies permanently.Your doctor can help you with this.

Depends. There are many types of food allergies. It would be dangerous to try giving small amounts of food if you have a classic food allergy (hives and anaphylaxis). The exception is milk and egg allergy: if you can eat "baked" milk and egg (e.g. Muffin or waffle) without a problem, this can help you tolerate regular milk and egg over time. It is best to discuss this with a trained allergy specialist. Read more...
Do not try. If this is a true food allergy you can make matters worse and not better by repeatedly challenging the body with food proteins. Protocols for food desensitization are currently being developed to be performed under the supervision of a clinician and should not be attempted until the have been approved and verified.
