T78: Adverse effects, not elsewhere classified

T78.1: Other adverse food reactions, not elsewhere classified

There are various reasons why a food is intolerable. For example, you may have an allergic reaction to the food. With an allergy, the immune system overreacts to certain substances. Such substances may be harmless substances in the environment, drugs or certain chemicals, for example. You may get heart palpitations or the skin on your face might suddenly get red and warm. There may also be other symptoms when one is intolerant to a food.
