YorkTest define Food Intolerance as a food-specific IgG reaction and have spent over 35 years researching and developing our knowledge in the field of diagnostic testing; we are leading providers of food-specific IgG antibody testing services and provide expert analysis of your unique IgG reactions to 158 food and drink ingredients.

Working alongside trained Nutritional Therapists, YorkTest have developed comprehensive programmes with individually tailored nutritional advice and support to help people balance their diets, optimizing their health and wellbeing.

According to research carried out by Allergy UK, it is thought that up to 45% of the UK population has some kind of food sensitivity or intolerance.

Whilst these reactions are not as severe as allergies, intolerance has been associated with a wide range of disruptive conditions such as migraines, slow digestion, bloating, cramps, IBS, skin issues and fatigue which can naturally impact sports performance, self-esteem, etc.

When food particles enter the bloodstream, the immune system can sometimes identify these food protein particles as “foreign” and produces IgG antibodies to “attack” the food in question. This response is your immune system’s natural defence mechanism to ward off harmful invaders in the body which can create inflammation.

This inflammation could trigger bothersome symptoms, which may persist or develop in the body if they are neglected. Imagine if you stopped brushing your teeth twice a day. The more foods and drinks you consume, the more bacteria lands on your teeth. Through this neglection, over time you may see a build-up of plaque, bad breath and discolouration which may lead to problems, such as tooth decay. Food intolerance can build up in the same way and could create further problems as the root cause hasn’t been addressed.

The results will arrive in a pack, which contains a food and drink diary, a support booklet and a food intolerance ID card (ideal for showing your waiter when dining out).

Comprehensive colour-coded results of your test within ten days. These will summarise the complete list of ingredients in three categories. If a food or drink appears in the green column, this means there is no reaction to that ingredient. Should it appear in the red or amber column, this means that a strong (red) or borderline (amber) IgG reaction has been detected.

YorkTest provide free telephone consultations with our NANP registered Nutritional Therapists as a way to optimize your diet after the sample results have been analysed. Finding your food triggers could ultimately optimise your diet and improve your general health.
