Dairy Products
For some individuals, dairy products can be a major headache trigger. This is often due to lactose intolerance or sensitivity to casein, a protein found in milk and other dairy products. Headaches caused by dairy consumption are usually accompanied by other digestive symptoms, such as bloating or gas.
Gluten-Containing Foods
Gluten is a protein found in wheat, barley, and rye, and is a common trigger for headaches in individuals with gluten sensitivity or celiac disease. Headaches caused by gluten consumption are usually accompanied by other gastrointestinal symptoms, such as abdominal pain or Diarrhea.
Citrus Fruits and Aged Cheeses
While citrus fruits and aged cheeses are generally healthy and delicious, they can be problematic for some individuals who suffer from headaches. These foods contain a compound called tyramine, which has been linked to migraines and cluster headaches.
