Some individuals have an autoimmune condition called Celiac Disease (CD). This is a genetic disease where gluten, when it is digested, causes the person's immune system to attack the inner-lining of the small-intestine. When this inner-lining, or the villi are damaged, individuals have a harder time absorbing important nutrients such as vitamins, minerals, and macronutrients. This autoimmune disease can have devastating effects including gastrointestinal distress, osteoporosis, certain types of cancers, and mineral and vitamin deficiencies. Symptoms of CD can range from diarrhea, abdominal pain, and headaches to vomiting, weight loss, and behavioral problems when exposed to gluten-containing foods.
