Most of the conditions above can be associated with a particular food or drink you consume. Getting better is simply a matter of identifying and avoiding foods that make you feel unwell. ​ Food sensitivity testing is key to getting your life back and enjoying the everyday things people take for granted... Absence of an enzyme needed to fully digest a food. Lactose intolerance is a common example. ​ Irritable bowel syndrome. This chronic condition can cause cramping, constipation and diarrhoea. ​ Sensitivity to food additives. For example, sulfites used to preserve dried fruit, canned goods and wine can trigger asthma attacks in sensitive people. ​ Recurring stress or psychological factors. Sometimes the mere thought of a food may make you sick. The reason is not fully understood. ​ Celiac disease. Celiac disease has some features of a true food allergy because it involves the immune system. However, symptoms are mostly gastrointestinal, and people with celiac disease are not at risk of anaphylaxis. This chronic digestive condition is triggered by eating gluten, a protein found in wheat and other grains.
