What is Food Intolerance?
Food intolerance is much more common than food allergy. The onset of symptoms is usually slower and may be delayed by many hours after eating the offending food. The symptoms may also last for several hours, even into the next day and sometimes longer. Intolerance to several foods or a group of foods is not uncommon, and it can be much more difficult to decide whether food intolerance is the cause of chronic illness, and which foods or substances may be responsible.
With a food allergy, the patient cannot usually tolerate even a small amount of the offending food without suffering symptoms, as it only takes a tiny amount to trigger a response from the immune system, but with food intolerance some sufferers can tolerate a reasonable amount of the food, but if they eat too much (or too often) they get symptoms because their body cannot tolerate unlimited amounts.
What are the symptoms?
The symptoms caused by food intolerance are varied. They can include general symptoms such as fatigue, joint pains, dark circles under the eyes, night sweats, gastrointestinal symptoms such as diarrhoea and vomiting, bloating, irritable bowel, skin symptoms such as rashes, eczema, and other chronic conditions.
