The first time I met someone with celiac disease (sensitivity to gluten in wheat, barley, etc.) I was amazed with the change in their health, including their dental health, when they were diagnosed and began to follow a gluten free diet. Many people are also sensitive to the proteins in dairy products, which can cause chronic inflammation and headaches. According to the Food Allergy Initiative (http://www.faiusa.org), dairy allergy is the most common allergy found in infants and children and can continue to cause problems for some adults. If you have run out of ideas to improve your health, consider researching the concept of a food elimination diet. With a food elimination diet, you pick a food or food component and eliminate that food from your diet for a period of time. Your doctor or dietician can help you plan your diet to make sure you are getting the appropriate nutrients.
