attention of a vegetable smoothie, rich in berries, fruits and
vegetables, served at the mid-morning brake. The smoothie was
designed to provide only 5% of the daily energy. The effect was
assessed by the D2-test of attention.
Participants and setting:
Pupils, aged 10 to 12 years, from twelve school classes in southern
Sweden, were invited to participate in the study. In total 250
children participated. Children suffering from serious food allergies
or food intolerance were excluded from the study.

periods of ten schooldays. The children were randomly divided
into two groups and were administered either an active smoothie
(smoothie 1; group A) or a fruit-based placebo with the same
energy content (smoothie 2; group B). After a three week washout
period, group A was administered smoothie 2 and group B,
Prior to the study, all children answered a questionnaire about their
consumption of fruit, berries and vegetables, physical activity habit
and and their perceived hunger during the school day. Age, height
