Food Intolerance

Food intolerances are often confused with allergies, but have different causes and symptoms. Unlike food allergies, which are caused by the body producing antibodies as part of an (IgE) immune response, food intolerance can be attributed to the lack of certain enzymes in the gut as well as an immune (IgG) response to specific proteins in food.

About Food Intolerance

Unlike true allergies which can provoke a strong, reliable reaction, the symptoms of food intolerances vary and can be quite general. Common symptoms include digestive discomfort, bloating, diahhorea, constipation and fatigue. The onset of symptoms can often occur several hours after having eaten the particular food, meaning that diagnosis is difficult; it is hard to identify which part of a meal has caused the reaction.

Our food intolerance tests are identifying those foods which cause an IgG response in the body. An IgG respnse is an immune response to the proteins in foods. It occurs when proteins in food escape the gut (due to leaky gut) and enter the bloodstream where they are attacked by the body's antibodies. This causes inflammation to occur which can cause a number of symptoms from headaches, to jont pain to gastro-intestinal discomfort. See Symptoms for a comprehensive list of symptoms. 

Our tests identify those foods to which you have a strong reaction (reaction foods) and those where the reaction is borderline. You may or may not benefit from eliminating borderline foods from your diet, whereas eliminating reaction foods is often beneficial. 

Why have a Food Intolerance Screen?

Our Food Intolerance test allow you to accurately pinpoint whether a food or drink you consume is causing your symptoms so that you can modify your diet accordingly. You may just 'suffer in silence' with unpleasant symptoms through not knowing exactly what it is that is causing your discomfort; having an intolerance test gives you information you can act upon to improve your symptoms.
