Frequently Asked Questions

What is the difference between food allergy and food intolerance?

Up to 45% of the population suffer from intolerances which, whilst not life threatening, can have a negative impact on many aspects of daily life.

Doing an food intolerance test takes the guesswork out of what is causing those irritating symptoms. The personalized OptiWay report that you receive with your ideal food choices neatly categorized into red (to avoid), yellow (to eat in moderation) and green (to eat liberally) will help you to optimise your eating plan and eliminate the foods that your body does not enjoy. This way, you can ensure that you diet works for you and not against you.

This can also help to improve your overall fitness performance by providing your body with the nutrients and foods that it really needs.

It can be stressful to constantly experience symptoms after eating, not knowing the cause. It is not good for your mental wellbeing to fear developing these symptoms every time you sit down for a meal.

The OptiWay test will help reduce this stress by empowering you to make the appropriate changes to your diet and live your healthiest life. The OptiWay test is accurate and fast. Depending on when your sample is received, results are made available within a short period of time, personalized to you. You will find out exactly where the problem lies, and how to avoid it.

Planning what you eat can go a long way to ensuring your future healthy lifestyle.

I have been avoiding a food for several months/years; will this affect my test results?

The IgG food intolerance test is based on your immune system producing antibodies in response to you eating certain foods. If you have been avoiding a particular food, your body may be producing insufficient antibodies to be detected by the test. You may therefore show a negative response. To ensure a reliable result, you should include that food in your diet daily for at least 6 weeks before testing. However, if you know that the food concerned causes you extreme symptoms do not reintroduce that food at all.

What does U/ml mean?

U/ml stands for Units per millilitre and is a measure of concentration. All positive results on the Food Intolerance Test report are expressed in U/ml to show the concentration of IgG antibodies in the blood.

Do I need to visit a nutritionist to discuss these results?

Once you have received your results, we advise you to see nutritional therapist registered with the British Association of Applied Nutrition and Nutritional Therapy (www.bant.org.uk), who will advise you how to eliminate foods from your diet and which foods you should substitute to ensure you are eating a healthy, balanced diet. They may also offer support and encouragement with regular progress checks, as it can be quite a daunting task sticking to a new diet on your own.
