Blood Glucose Response
Conditions
Brief summary
The aim of this study is to investigate second meal effects of a wholegrain cereal product on blood glucose response. The wholegrain cereal product will be consumed in the evening and blood glucose analyzed after a standardized breakfast meal the following morning.
