All of the reports support the role for fiber-rich foods and dietary fiber (DF) as an important part of a healthy diet. All of the five identified Nordic papers found protective associations between high intake of DF and health outcomes; lower risk of cardiovascular disease, type 2 diabetes, colorectal and breast cancer.

None of the reports and few of the Nordic papers found clear evidence for the Glycemix Index (GI) in the prevention of risk factors or diseases in healthy populations, although association was found in subgroups, e.g., overweight and obese individuals and suggestive for prevention of type 2 diabetes.

It was concluded that DF is associated with decreased risk of different chronic diseases and metabolic conditions. There is not enough evidence that choosing foods with low GI will decrease the risk of chronic diseases in the population overall.

However, there is suggestive evidence that ranking food based on their GI might be of use for overweight and obese individuals. Issues regarding methodology, validity and practicality of the GI remain to be clarified.
