What is a food allergy?

  • What is the difference between food allergy and food intolerance? Thank you.

  • Answer:

    an allergy is where your body produces too much histamine, where an intolerance is something in the food that upsets your digestive system. Allergies can be severe and in some cases cause anaphylactic reactions, but an intolerance will normally just be unpleasant and result in an upset stomach, stomach cramps, diarrhea, and occasionally vomiting. A person with an intolerance only has to avoid a certain trigger but somebody with an allergy needs to spend time meticulously reading food labels to double check it might not contain traces of their allergen.

Because each person's genetics are unique, some chemicals that are harmless to most people can be deadly poisonous to certain people. The body has an immune system response to poisons which include producing a lot of histamine which restricts the airway as well as does other things to prevent more poison from entering the body. When the body's immune system response is activated by a chemical, then the body is allergic to that chemical. So a food allergy is a food that is poisonous and that sets off an immune system response. A food intolerance on the other hand, is a poisonous food that does not set off an immune system response. Food intolerance can result in headaches, lowered I.Q., clinical depression, irritable bowel, Crohns syndrome, paralysis, runny stool, gas, etc. Mixing Aspirin with alcohol has a similar effect. Don't do it; it can be deadly. Chocolate is poisonous to dogs. Dogs have a food intolerance to chocolate. Too much will surely kill them. But they are not allergic to it.
