The 10 Most Common Food Intolerances

Along with food allergies, food intolerances are a type of food hypersensitivity. Though some symptoms are quite similar, the two conditions are not the same. People with food intolerance often experience problems after several hours of eating. In some cases, they would be delayed up to 2 days, making it hard to pinpoint the culprit. Common symptoms include rashes, bloating, diarrhea, nausea, fatigue, headaches, runny nose, abdominal pain, or skin flushing. Below are the 10 most common food intolerances that you should know.


Gluten is a general term for proteins in triticale, rye, barley, and wheat. Some conditions are associated with this element, including wheat allergy, non-celiac gluten sensitivity, and celiac disease. Celiac disease occurs when the immune system mistakenly attacks your small intestine and does harm to the digestive system. Non-celiac gluten sensitivity is a mild type of gluten intolerance. Typical symptoms include headaches, constipation, diarrhea, abdominal pain, bloating, anemia, anxiety, depression, skin rash, joint pain, or fatigue. These problems can be managed by following a gluten-free diet, which should be free from cereals, pasta, bread, crackers, baked goods, or beer.[1]
