According to the American Academy of Allergy Asthma & Immunology, food intolerance is defined as having difficulties digesting a certain food element that may cause symptoms, such as abdominal cramps, bloating, and gas.
A food intolerance is different from a food allergy, with the latter being more serious. If you want to learn more about the difference between the two conditions, check out this article (insert link of intolerance vs sensitivity article).
The most common food intolerance is lactose intolerance, which we have covered in greater detail in our other article (insert link of lactose intolerance article).
Causes of food intolerance
There are many causes of food intolerance, including:
Enzyme deficiency
Most macronutrients are metabolized by specific enzymes secreted by the stomach, liver, and pancreas. When one of these enzymes is deficient, the body is no longer able to digest that food element. As a result, symptoms of indigestion occur.
Food toxins
Some foods are rich in chemical substances that irritate the intestinal lining, leading to symptoms of diarrhea, nausea, and vomiting.
This is often the result of undercooking our food. For instance, beans are a rich source of chemicals known as aflatoxins, which can cause serious digestive symptoms.
Histamine intolerance
Histamine intolerance is the result of consuming foods rich in histamine; this process could lead to symptoms similar to food intolerance, including hives, skin rash, and indigestion.

Treatment options
The only viable treatment option for food intolerance is to identify the exact element that’s causing your symptoms. This could be done via allergic testing at a clinic or from the comfort of your home.
