This study will investigate the effect of a 12 week intervention with a portfolio of 7 food products and 7 comparator products for their effect on glycated hemoglobin, blood lipids, blood vessel function and metabolic parameters in persons with prediabetes. Prediabetes precedes the manifestation of type 2 diabetes and is therefore an appropriate target for dietary interventions. It is also associated with increased cardiovascular disease (CVD) risk because of the presence of abdominal obesity, elevated LDL-cholesterol and reduced vascular function. CVD risk will be assessed based on the profile of lipids and other factors in the blood as well using specialized equipment for non-invasive monitoring of blood vessel function.
