Clinical Trial Summary

High intake of dietary fiber provides health benefits and reduces the risk of developing cardio-metabolic diseases, such as type 2 diabetes (T2D) and cardiovascular disease (CVD). The intake of fiber is below the recommendations worldwide. In Norway, bread and cereals represent a major source of fiber. A low fiber intake is evident for people with celiac disease due to the removal of wheat, rye and barley from the diet. We therefore need to increase our knowledge in relation to fiber-rich food that will be tolerated also by people with celiac disease. The aim of the study is to investigate the effect of fiber rich gluten free products on blood glucose levels compared to benchmark gluten free products.
