A food intolerance is a bad reaction to a food, but without involving the immune system.

Food intolerance is an adverse reaction to a particular food or ingredient, which occurs every time the food is eaten. Food intolerance is when the body is unable to deal with a certain foodstuff, usually because it doesn’t produce enough of the chemical or enzyme needed to properly digest that particular food. One of the most common intolerances is to cow’s milk, which contains a certain type of sugar called lactose.

“Frustrated parents, along with irritated children, presenting with itchy, red, bleeding, and puss-filled skin sores are cases we see all too often at The Liosbaun Clinic,” according to Yvonne O' Shaughnessy, nutritionist and leading food intolerance specialist at the clinic. “The occurrence of eczema in children is far more prevalent nowadays, and I see it being related mainly to diet but also other environmental factors a lot of the time.”

A food allergy happens almost immediately, usually within one hour. This reaction is very evident.

What is the difference between food allergy and food intolerance and how do you know if you have either or both? Food/chemical/environmental allergy occurs in response to exposure to a substance which the immune system perceives as a threat. The immune system responds with an over reaction in an attempt to detoxify the offending substance to protect the body. Symptoms tend to be instant and can vary from mild discomfort to anaphylactic and life threatening. Intolerance on the other hand occurs in response to the accumulation of toxins and indigestible food substances which settle in layers on the small intestine wall and accumulate in the organs and tissues of the body. Symptoms tend to be chronic, ongoing and recurring. Intolerance affects a larger number of people than allergy.
