This is reply of another postCoeliac or Celiac disease is a condition in which gluten damages the villi (tiny finger like protrusions lining the small intestine) preventing the body from absorbing parts of food that are important for staying healthy. Without healty villi, a person becomes malnourished, no matter how much food is eaten.
Gluten or alike proteins are contained in wheat, barley, spelt, rye and oats.
This is said that 7 out of 9 are not aware of the disease they are suffering from.
