Food Intolerance

What are Food Intolerances?

food Intolerance is an adverse reaction to eating or drinking certain foods or drinks. The food or drink type that triggers these reactions, as well as the type and severity of the reaction can be wide ranging – no two people will be exactly the same. Food Intolerance is recognised by both the NHS and the World Allergy Organisation, as well as by the UK’s Food Standard Agency and the Food Industry itself.

Allergy or Intolerance - Avoid Confusion.

Food allergies are caused by your body producing IgE antibodies in response to the ingestion of a food or drink – symptoms can appear within seconds and can result in severe reactions such as a rash, itchy skin, breathing difficulties, swelling or anaphylaxis. Smartblood DOES NOT test for food allergies – if you think that you may have a food allergy you should consult your usual Doctor.

Food Intolerances tend to appear an hour or more after eating a trigger food. Smartblood defines a food intolerance as a food or drink specific IgG reaction. There are estimated to be 9 million(1) adults in the UK with a food intolerance, with symptoms such as bloating, IBS, fatigue, weight gain, migraines, brain fog or joint pain.

The gold standard of detecting food sensitivities is a tedious trial and error elimination diet which, if completed successfully, can take many months. Through offering IgG food Intolerance Testing via ELISA plate studies, we offer you a way to take control of your food intolerances sooner with the gold standard of IgG testing, a home test kit from Smartblood Laboratories.
