    Could a smoothie, rich in nutrients and bioactive substances, improve school performance?2015In: Annals of Nutrition and Metabolism, ISSN 0250-6807, E-ISSN 1421-9697, Vol. 67, no Suppl. 1, p. 212-, article id 149/1319Article in journal (Refereed)
    Abstract [en]

    Introduction: Fruits and vegetables contain vitamins, minerals and other bioactive substances, which are important for intellectual performance. In a previous study it was shown that approximately two third of the pupils were hungry the last lesson before lunch. The average fruit and vegetable intake at lunch was much lower than the recommendations.

    Objectives: The purpose of this pilot study was to investigate effect on attention and school performance of a vegetable smoothie, rich in berries, fruits and vegetables, served at the mid-morning brake.

    Method / Design: In total 250 Swedish children aged 10-12 years participated. The study was designed as a cross-over trial with two 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). Both smoothies were designed to provide 5% of the daily energy. After a three week wash-out period, group A was administered smoothie 2 and group B, smoothie 1. Statistical tests were performed using SPSS package, version 22.0, using Independent-Samples T test. Analysis included processing speed (PTO), concentration performance (CP) and percentages of error (Ep) as assessed by the D2-test

    Results: Preliminary analyses indicate that PTO and CP increased during the intervention period, whilst Ep decreased, for both groups. The effect was stronger in the group drinking the active smoothie, than in the group drinking the placebo. The effect might partly be caused by the addition of water and energy

    Conclusions: Attention, and thereby also school performance, may be improved by mid-morning consumption of a smoothie containing water, energy and preferably nutrients and other bioactive substances.

    Effect on attention of a vegetable smoothie, rich in berries, fruits

    and vegetables, served at the school mid-morning brake. Viktoria

    Ohlsson. Kristianstad University

    Purpose:

    The purpose of this pilot study was to investigate effect on

    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.

    Data collection:

    The study was designed as a cross-over trial with two 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,

    smoothie 1.

    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

    and weight was also recorded.

    Data analysis:

    Analysis of the data focused on concentration performance as

    assessed by the D2-test.

    Methodological considerations in a pilot study on the effects of a berry enriched smoothie on children’s performance in school2017In: Food & Nutrition Research, Vol. 61, no 1Article in journal (Refereed)
    Abstract [en]

    Berries contain bioactive compounds that may affect children’s cognitive function positively, while hunger and thirst during lessons before lunch affect academic performance negatively. This pilot study addresses methodological challenges in studying if a berry smoothie, offered to schoolchildren as a mid-morning beverage, affects academic performance.

    The objective was to investigate if a cross-over design can be used to study these effects in a school setting.

    Therefore, in order to investigate assay sensitivity, 236 Swedish children aged 10–12 years were administered either a berry smoothie (active) or a fruit-based control beverage after their mid-morning break. Both beverages provided 5% of child daily energy intake. In total, 91% of participants completed the study. Academic performance was assessed using the d2 test of attention. Statistical analyses were performed using the Wilcoxon signed rank test in StatXact v 10.3.

    The results showed that the children consumed less of the active berry smoothie than the control (154 g vs. 246 g). Both beverages increased attention span and concentration significantly (p = 0.000). However, as there was no significant difference (p = 0.938) in the magnitude of this effect between the active and control beverages, the assay sensitivity of the study design was not proven. The effect of the beverages on academic performance was attributed the supplementation of water and energy.

    Despite careful design, the active smoothie was less accepted than the control. This could be explained by un-familiar sensory characteristics and peer influence, stressing the importance of sensory similarity and challenges to perform a study in school settings. The employed cross-over design did not reveal any effects of bioactive compound consumption on academic performance. In future studies, the experimental set up should be modified or replaced by e.g. the parallel study design, in order to provide conclusive results.
