Some people have mild reactions to food that are not as severe as allergic reactions but can still cause pain or discomfort. These symptoms are collectively called ‘Food Intolerances’. They can appear in the skin (e.g. rashes, itchiness, eczema, hives or swelling), the gut (e.g. pain, wind, bloating, diarrhoea, constipation, reflux or nausea), the airways (e.g. asthma like symptoms, nasal congestion, shortness of breath), the central nervous system (headaches, migraines or painful joints) or can be a general feeling of being unwell.
