Over 45% of the population react adversely to foods that they eat, which whilst not life threatening, can have a massive impact on someone’s quality of work and home life.

The way that food can affect our everyday life is often difficult to explain and it is common for people to try and eliminate foods from their diet to help themselves feel better. Often they don’t know which foods to try and eliminate and have to guess. Many people don’t know that identifying food intolerances† can be an important element of optimising health and wellbeing.

Lorisian, has over 30 years’ experience, specialising in laboratory tests that measure food triggers (food-specific IgG antibodies).  Our results offer a fast track or starting point for an elimination diet.  The tests are aimed at those that may have food intolerances†, and those who want to optimise their diets by avoiding any foods that they are reacting to.  Our aim is to promote wellbeing within the pressures of a modern lifestyle. There are 3 testing options available with reactions to 75, 100 or 150 different food ingredients tested.

† Food intolerance is a condition with a range of symptoms including gut symptoms, bloating, headaches, migraines, low mood, fatigue, weight gain and skin problems. These symptoms must always be checked out by a Medical Professional. If you have clients that have seen a Medical Professional but have not been given a diagnosis for their symptoms then they may be suffering from food intolerance.

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.

Functional Testing Prices

Functional Testing is a way to “see” inside your body. If we need to dive in deeper into your health concerns I will recommend testing. It takes all the guess work out. e.g. Stool analysis is the Gold Standard at looking at the health of your gut. It looks at how well you digest proteins, fats and carbohydrates and  the types of bacterias, yeasts and parasites that are potentially upsetting the natural balance. (prices subject to change)
