People may have a reaction to peanuts that isn't caused by an allergy. Peanut allergy is the immune system's negative reaction to peanut protein. Peanut intolerance is different because it involves a reaction of the digestive system rather than the immune system. Symptoms of intolerance are usually just mildly uncomfortable and may include indigestion or heartburn. People who are peanut intolerant are usually able to eat small amounts of peanut without too much of a reaction. People with peanut allergy, on the other hand, may experience severe symptoms after being exposed to the tiniest amount of peanut.
