Food intolerances to certain foods occur due to a number of reasons which invariably relate to gut issues. There could be a number of different causes but the root cause can often be traced back to the use of antibiotics or perhaps a past illness. Food intolerances are commonly confused with food allergies, however, there is a key difference between the two.
A food allergy is a response by the body’s immune system which has mistakenly diagnosed a harmless protein or food as a threat – this response can trigger severe symptoms and usually happens very quickly, in the worst-case scenario, they can be life-threatening.
Food intolerance still involves the immune system but is not usually life-threatening – unlike a food allergy. Symptoms are usually gradual, appearing steadily after a few hours up to days later after eating a certain food or foods. The range from heart burn to brain fog, dry or watery eyes, muscle aches and joint pains and common skin conditions.
