Impact of a wholegrain breakfast cereal meal on blood glucose level, mood and affect

Following either consumption of breakfast or no food, university students undertook a morning of sustained cognitive activity during which they completed self-ratings of mood and affect. In the Breakfast group, blood glucose levels increased and there were also significant effects on self-ratings of alertness, contentedness and satiety. No such effects were observed in the No Breakfast group. Taken together, these findings demonstrate the importance of breakfast consumption for maintaining blood glucose level, mood and affect during the course of a morning of cognitive activity.
