What is food intolerance?
 
Food intolerance is di erent from allergies. An allergy sees the body trigger IgE antibodies immediately upon consuming a particular food. Allergies can cause serious symptoms, like di culty breathing, an itchy rash or swelling, even anaphylactic shock.
 
With a food intolerance, the body creates a di erent type of antibodies, namely IgG rather than IgE. These antibodies cause slower, more subtle reactions to the foodstu , with symptoms not appearing until two to three days after eating.
 
Food intolerance can be divided into two basic types. Food poisoning, a toxic reaction. The other type of intolerance is a non-toxic reaction. This occurs when the body has di culty digesting the nutrients, leading to abnormal symptoms in the gastrointestinal system.

Along with hereditary conditions, there can be many causes of food intolerance. Symptoms can include an infirm gastrointestinal immune system, an ine cient digestive system, problems with absorption, and an imbalance of microorganisms in the intestine.
