  • If you have a blood borne disease such as Hepatitis or HIV, Lorisian will not test these samples.
  • If you are taking any medication such as steroids or immunosuppressants, this can affect the test – we need to know how long you have been taking the medication and at what dosage. Please click here to read more about taking steroids or immunosuppressants and our food tolerance test.

An Explanation of Food Intolerance

What is the difference between allergy and intolerance?

The term ‘food intolerance’ and ‘food allergy’ are often confused and are two very different things.

Genuine food allergy is relatively rare.  Only about 2% of the adult population are affected.  A food allergy is a swift response by the body’s immune system to a specific food.  In this type of reaction, the body’s immune system mistakes a food for an ‘invader’ which often results in a rapid allergic reaction often within minutes, but generally within a maximum of two hours.  This type of allergic reaction is commonly associated reactions to peanuts, tree nuts, milk, eggs and seafood.

Food intolerance is quite different to food allergy and whilst the symptoms can impact the person’s quality of life they are not life threatening.  Food intolerances are much more common than food allergies.

When foods and drinks are digested the proteins within them are broken down into smaller fragments for easy absorption into the body.  Larger fragments can pass through without breaking down, and sometimes the body reacts by attacking them using antibodies called Immunoglobulin G’s (IgG).

A recent study* has shown that those who eliminated trigger foods based on food-specific IgG test results had reductions in weight, body mass index, waist and hip circumference and improvements in all indicators of quality of life that were measured. The quality of life indicators included physical and emotional wellbeing, mental health, social life, pain levels and vitality.

Symptoms of food intolerance can take up to 72 hours to appear after eating the trigger food or group of foods.  On average people who suffer from food intolerances usually have between 4 and 8 trigger foods.

Many people suffer for years, having formed a coping mechanism to deal with the symptoms but being unable to enjoy a normal work and home life.  Many people don’t realise that there are easy steps to take that could resolve their condition.
