  text: '<jats:title>Abstract</jats:title><jats:p>Studies about effects of school
    lunch on children’s cognition are rare; two previous studies (CogniDo, CogniDo
    PLUS) generally found no negative effects of lunch on children’s cognitive performance
    at the end of lunch break (i.e. 45 min after finishing lunch), but suggested potential
    beneficial effects for single parameters. Therefore, the present study investigated
    the hypothesis of potential positive effects of school lunch on cognitive performance
    at early afternoon (90 min after finishing lunch). A randomised, cross-over intervention
    trial was conducted at a comprehensive school with fifth and sixth grade students.
    Participants were randomised into two groups: On day 1, group 1 did not eat lunch,
    whereas group 2 received lunch <jats:italic>ad libitum</jats:italic>. On day 2
    (1 week later), group 2 did not eat lunch and group 1 received lunch <jats:italic>ad
    libitum</jats:italic>. The cognitive parameters task switching, working memory
    updating and alertness were tested using a computerised test battery 90 min after
    finishing the meal. Of the 204 recruited children, fifty were excluded because
    of deviations from the study protocol or absence on one of the 2 test days, which
    resulted in 154 participants. Data showed no significant effects of lunch on task
    switching, working memory updating and alertness (<jats:italic>P</jats:italic>
    values between 0·07 and 0·79). The present study suggests that school lunch does
    not seem to have beneficial effects on children’s cognitive functions regarding
    the conducted tests at early afternoon. Together with our previous studies, we
    conclude that school lunch in general has no negative effects on cognitive performance
    in children. However, beneficial effects seem to be restricted to a relatively
    short time period after eating lunch.</jats:p>'
