what is the best treatment for allergy?

Many people believe they're allergic to specific foods. But true food allergies aren't nearly as common as you might think. About 1 percent of adults and 5 percent of children actually have a true food allergy — an adverse reaction to a food that is triggered by the immune system. Far more people have a food intolerance, an unpleasant reaction to food that doesn't involve the immune system

well yeah prevention is the most logical thing to do ..than cure...however if you really cant do such things then go to the doctor right away to be treated immediately..
