What causes a food intolerance and how is it different from a food allergy?

Food intolerance symptoms are varied and can be very disruptive to a person’s life. They may occur when you experience a food-specific IgG reaction, which has been described as an ‘intolerance’ to a particular food or drink. The body can produce a range of inflammatory responses if it incorrectly identifies the ingredient as a threat.

The effects of a food intolerance are very different to an allergic reaction, which is an immediate reaction experienced by those suffering with food allergies. Unlike allergic reactions, the immune responses associated with a food intolerance are thought to be delayed for up to 72 hours.

Why get tested for food intolerance?

Understanding your own personal food and drink intolerances, and the effects they could have on your health and wellbeing, is important to ensure you make the best possible choices for your diet.
