Food intolerance refers to difficulty digesting certain foods and can cause many different types of reactions in the body.
Foods most commonly associated with food intolerance include dairy products, gluten-containing grains, and foods that cause gas formation in the intestines, such as beans and cabbage.
Finding out which foods are causing your symptoms can be easy for some people and incredibly difficult for others, depending on what your symptoms are; how quickly symptoms appear after consuming a food and what food (or food) is causing the problem.
