Allergy and Food Sensitivity
It is natural for an allergy to be confused with food intolerance, although the two are poles apart right from the chemical intricacies that set them apart to the reactions that they invoke respectively in the body.
A food allergy is when certain proteins in the meal act as allergens that bind to the IgE antibodies, triggering sneezing, coughing, and the typical allergy response.
On the other hand, an intolerance does not involve the IgE-mediated response but rather a different mechanism of action. It can be caused by the inability of the body to absorb carbohydrates, certain chemicals in the food due to the absence of an enzyme that is usually involved in the absorption of these.
Another reason for food intolerances is when the intestinal permeability is affected due to some reason. In simple terms, the chemical composition of the food irritates the digestive system, causing symptoms such as gas, nausea, severe pain in the stomach, and even diarrhoea.
