Both food allergies and food intolerance have common symptoms but they are both different conditions. Most physical reactions to certain foods are caused by a food intolerance and not a food allergy. The signs and symptoms of both are similar and one is often confused for the other.
Let’s first talk of food allergy. It can be explained as the reaction of the immune system to a type of food, which it sees as an invader. A food allergy triggers the immune system to react in a way that it can affect numerous organs in the body. What follows can be a whole range of symptoms. An allergic food reaction, can at times be so severe as to be life-threatening. On the other hand, food intolerance symptoms are not so serious and can often be seen in the form of limited digestive problems.
