Nut Intolerance

A nut intolerance is very different than an allergy. In an allergy, the body’s autoimmune system’s response to substances it considers a harmful antigen. In a food allergy the body mistakes certain proteins in food as harmful and creates an inflammatory response. In a food intolerance, rather than the offensive food setting off an autoimmune response, instead it usually just disrupts or upsets the digestive tract. The common nut intolerances are peanuts and tree nuts (such as walnuts, pecans, almonds).
Signs and symptoms of a nut intolerance include: nausea, stomach pain, gas, cramps, bloating, vomiting, diarrhea, heartburn, headaches, and gastric irritability.

Increased sensitization to any nuts will occur with prolonged exposure to the particular nut generating variations of allergic reactions from mild to extreme symptoms.
