Understanding Food Sensitivities

A food sensitivity, or a food intolerance occurs when a person has difficulty digesting a particular food. This can lead to symptoms such as intestinal gas, abdominal pain or diarrhoea. When the body is sensitive to certain foods, there are some common symptoms to be aware of. If you have one or more of these symptoms on a daily basis, then start paying attention to what you regularly eat.

A food intolerance is sometimes confused with or mislabelled as a food allergy. Food sensitivities/ intolerances involve the digestive system. Food allergies involve the immune system. With a food allergy, even a microscopic amount of the food has the potential to lead to a serious or life-threatening reaction called anaphylaxis.
