Study design: cross-over trial placebo-controlled
Sample:10 Finnish healthy habitual breakfast eaters volunteers performed work-like tasks in the lab after having a breakfast drink:
Test visit 1: high-protein drink for breakfast (HP)
Test visit 2: high-carbohydrate drink for breakfast (HC)
Test visit 3: low energy placebo drink for breakfast (control)
Although the drinks appearance, the subjects were unaware of the content.
During the work simulation compared with the control drink
- HP increased the feeling of well-being (pleased, relaxed, vigour and satisfied )
- HC reduced subjective sleepiness and can improve mood before stress onset
- HP and HC drinks significantly attenuated the heart rate increase
How do you feel at work? What do you eat for breakfast???
