What Is The Difference Between A Food Allergy And Intolerance?
Food intolerances are different from food allergies in the sense that the symptoms and mechanisms by which the two occur are unique. While a food allergy triggers the immune system and causes a typical reaction that would occur if the body encountered a pathogen or dust or pollen, a food intolerance triggers the digestive system. Food allergies can be severe or often even life-threatening while intolerances are milder, although notorious in their own way.
Another difference between allergies and intolerances is the amount of trigger needed to offset a reaction. While allergic reactions are seen even in cases that a person is mildly exposed to the allergen or microscopic amounts of it, someone with food intolerance can afford to eat a little of the food without experiencing any major symptoms.
