Food Intolerance
According to the American Academy of Allergy, Asthma & Immunology, food intolerance is defined as difficulty digesting a particular food, which may result in symptoms such as abdominal cramps, bloating, and gas.
Food intolerance differs from a food allergy, with the latter involving an immune response and potentially more serious reactions. If you would like to learn more about the differences between these two conditions, read our article on food intolerance vs. food allergy. (Insert link)
One of the most common food intolerances is lactose intolerance, which we discuss in greater detail in our dedicated article. (Insert link)
Causes of Food Intolerance
There are several possible causes of food intolerance, including:
Enzyme Deficiency
Many nutrients are broken down by specific enzymes produced by the digestive system. When the body does not produce enough of a particular enzyme, it may struggle to properly digest certain foods. This can lead to digestive symptoms such as bloating, abdominal discomfort, and diarrhea.
Lactose intolerance, for example, occurs when the body produces insufficient amounts of the enzyme lactase, which is needed to digest lactose found in dairy products.
Naturally Occurring Compounds in Foods
Some foods contain naturally occurring substances that may irritate the digestive tract or be difficult for certain individuals to tolerate. This can contribute to symptoms such as nausea, bloating, diarrhea, or abdominal pain.
In some cases, improper preparation or cooking of foods can increase the likelihood of digestive discomfort.
Histamine Intolerance
Histamine intolerance occurs when the body has difficulty breaking down histamine from foods. Histamine rich foods may trigger symptoms such as headaches, skin flushing, hives, digestive discomfort, or nasal congestion in sensitive individuals.

Sensitivity to Food Additives
Some individuals may experience symptoms after consuming certain food additives, including preservatives, artificial colorings, flavor enhancers, or sweeteners. These reactions can vary from person to person and may affect digestion or general well being.
Identifying Food Intolerances
The most effective way to manage food intolerance is to identify the specific foods or substances triggering symptoms. This often involves a combination of symptom tracking, dietary adjustments, elimination diets, and testing when appropriate.
Understanding your individual triggers can help you make informed dietary choices and reduce unwanted symptoms while maintaining a balanced and varied diet.
