Intolerances to Caffeine and other drinks.
Intolerances to Caffeine and other drinks.
IgG sensitivities to coffee, tea and other drinks.
Caffeine is thought to be the main component of Coffee and Tea that may be responsible for a sensitivity to those drinks.
Manifesting as bloating, Irritable Bowel Syndrome (IBS), weight gain, fatigue, skin problems, migraines or joint pain, even a mild food intolerance to some drinks may have a major impact upon a person's day to day activities, and the inclusion of these foods in a western diet is so common that the actual intolerances can be difficult to find, and also to avoid successfully.

A Consultation with a Registered Nutritional Therapist.
Knowing which foods and drinks you are intolerant to is only half of the battle when it comes to improving how you feel. That is why, with every full Smartblood Programme, we include a 30 minute consultation with one of our Smartblood Nutritional Therapists, all of whom are registered with the British Association of Nutritional Therapists (BANT); between them they have helped tens of thousands of people adjust and improve their diet following a positive food intolerance test.












The Science behind the story
In a Randomised Controlled Trial Conducted by Atkinson, Sheldon, Shaath et al, a clinically significant improvement in symptomatology was observed in patients eliminating foods to which they were found to exhibit sensitivity, as identified by an ELISA test for the presence of IgG antibodies to these foods - see more details and studies on our scientific studies page.
