Allergens come in many forms. Through the air, by physical contact, or in the foods we eat.
Common allergens include mold and pollen from grasses, ragweed and trees.
Although 25 percent of people think they’re allergic to certain foods, studies show that about only 6 percent of children and 2 percent of adults have a food allergy.
What’s the difference between food allergy and food intolerance?
A true food allergy is a reaction triggered by the immune system (the part of your body that fights infection). Far more people simply have a food intolerance, which is unpleasant symptoms triggered by food (but does not involve the immune system).
