A food allergy is when your body’s immune system ... other symptoms can be easily confused with those of an intolerance – such as rashes and itchy skin, diarrhoea and sickness.

Symptoms of a food allergy can vary widely. They include rashes, hives, vomiting, diarrhea, abdominal pain, and difficulty breathing. Pay attention to these symptoms after consuming certain foods.
