A FOOD INTOLERANCE OR ALLERGY

For some people, certain foods can lead to food-hypersensitivity. ‘These reactions either involve the immune system, which is a “food allergy”, or in cases where it doesn’t, it’s called a “food intolerance”,’ explains Dr Emma Williams, Waitrose & Partners health manager.

SORT IT Food allergy: Immediate reactions usually take place within two hours of eating, with the development of symptoms like an itchy rash, swelling and, in some cases, vomiting and diarrhoea. ‘These can lead to serious problems, seek urgent medical advice,’ says Dr Williams. Food intolerance: Symptoms, such as bloating or tummy pain, often come on several hours after eating. Keeping a food diary will help you to identify possible triggers. Try eliminating certain foods for two to six weeks to see whether things improve.
