10 Signs of Food Sensitivity

10. Headaches

Another common sign of food sensitivity is a headache. There are many reasons behind this. First, inflammation can trigger pain in the muscles, causing a headache. Other symptoms of food sensitivity, like diarrhea, also have the potential to trigger headaches by causing dehydration. Finally, the same withdrawal-like symptoms that cause brain fog and confusion can lead to head pain. If you notice that you frequently get headaches after eating large quantities of a certain food, you should resolve to eliminate it from your diet. Food sensitivities to things like alcohol, chocolate, and gluten can even trigger debilitating migraine headaches that may require emergency care.
