Effects of consumption of snacks on simulated driving

The present study investigated the effects of snacks on simulated driving for 24 volunteers who carried out a driving task three times. On each occasion a presnack baseline of 1 hr. of driving was taken. The snack conditions were (a) no snack (b) a 65 g-filled chocolate bar, and (c) an equicaloric snack of cheese and biscuits. Following the snack the volunteers then carried out another hour of driving. Analysis showed that following consumption of the chocolate the volunteers drove more carefully and hit the side of the track less often.
