What’s the difference between an allergy and intolerance?

People often get confused between a food allergy and a food intolerance. A food allergy is different from food intolerance. A true food allergy causes an immune system reaction that affects numerous organs in the body. It can cause a range of symptoms. In some cases, an allergic food reaction can be severe or life-threatening. In contrast, food intolerance symptoms are generally less serious and often limited to digestive problems and can change depending on diet and lifestyle.
