Young Brunette Girl With Blue Eyes Reveals On A Wheat Field

Health concerns
Roughly 1% of Indian populations has coeliac (also written as celiac) disease—a condition that is caused by an adverse immune system reaction to gliadin, a gluten protein found in wheat (and similar proteins of the tribe Triticeae which includes other species such as barley and rye). Upon exposure to gliadin, the enzyme tissue transglutaminase modifies the protein, and the immune system cross-reacts with the bowel tissue, causing an inflammatory reaction. That leads to flattening of the lining of the small intestine, which interferes with the absorption of nutrients. The only effective treatment is a lifelong gluten-free diet.
The estimate for people in the United States is between 0.5 and 1.0 percent of the population.
While the disease is caused by a reaction to wheat proteins, it is not the same as wheat allergy.
