The researchers conclude that the threshold for gluten in the diets of those with celiac disease can safely be set at 100 ppm. Even those in the study who consumed flour at the high end--300g per day with a gluten level of 100 ppm--only consumed 30mg of gluten per day. The researchers determined that this level was safe when correlated to their histology in both clinical and challenge studies. Last, this level can be achieved by the food industry, will not make the diet too cumbersome, and will have the additional benefit of encouraging additional food companies to get into the gluten-free food market.
