d-Allulose (d-psicose) is a rare sugar, that contains no calories and exhibits 70% relative sweetness when compared with sucrose. Recently, several studies have demonstrated the anti-obesity effect of d-allulose, mediated by suppressing lipogenesis and increasing energy expenditure. Medium-chain triacylglycerols (MCTs) are lipids formed by 3 medium-chain fatty acids (MCFAs) with 6–12 carbon atoms attached to glycerol. MCTs have been expensively studied to reduce body fat accumulation in rats and humans. The anti-obesity effect of MCTs was not confirmed depending on the nutritional conditions because MCT might promote lipogenesis. In the present study, we examined the effects of simultaneous intake of diets containing low (5%) or high (13%) MCTs, with or without 5% d-allulose, on body fat accumulation in rats (Experiment 1). Furthermore, we assessed the interaction between 5% MCT and 5% d-allulose in the diet (Experiment 2). In Experiment 1, intra-abdominal adipose tissue weight was significantly greater in the high MCT diet groups than in the commercial diet (control) group. d-Allulose significantly decreased weights of intra-abdominal adipose tissue, carcass fat, and total body fat, however, these weights increased as the amount of MCT added increased. In Experiment 2, d-allulose significantly decreased almost all body fat indicators, and these values were not influenced by the presence or absence of MCT addition. The antiobesity effect of d-allulose was observed with or without dietary MCT, and no synergistic effect was detected between d-allulose and MCT. These results suggest that d-allulose is a beneficial food ingredient in diets aimed at reducing body fat accumulation. However, further research is required on the synergistic effects between d-allulose and MCTs.

高等教育のアウトカム重視傾向の高まりから、汎用的能力獲得における正課外の学習活動が果たす役割に注目が集まっている。そこで本研究では、ラーニングコモンズの活動に焦点をあて、学生スタッフの社会人基礎力1)への影響を検討することを目的とした。研究1では、学生スタッフの社会人基礎力に与える影響のうち、課外活動経験に注目し、学生スタッフ46名の社会人基礎力得点と、①アルバイト、②サークル活動(部活動を含む)、③教職課程履修、④SA経験、⑤一人暮らし経験の5つの課外活動経験の有無との関連を検討した結果、すべての項目に関して有意差は認められなかった。研究2では、学生スタッフ44名を対象にラーニングコモンズでの活動に関するアンケート調査を事前・事後の2回に分けて実施した。その結果、向上させたい力として【発信力】【働きかけ力】【主体性】を重要視する学生が多く、対人関係における社会的成長および人格的成長への志向性が確認できた。以上のことから、ラーニングコモンズにおける正課外活動実践は、社会人基礎力の発揮・向上の場となり得ることが示唆された。

This clinical study was conducted to investigate the safety and effect of D-psicose on postprandial blood glucose levels in adult men and women, including borderline diabetes patients. A randomized double-blind placebo-controlled crossover experiment of single ingestion was conducted on 26 subjects who consumed zero or 5 g of D-psicose in tea with a standard meal. The blood glucose levels at fasting and 30, 60, 90, and 120 min after the meal were compared. The blood glucose level was significantly lower 30 and 60 min after the meal with D-psicose (p<0.01, p<0.05), and a significant decrease was also shown in the area under the curve (p<0.01). The results suggest that D-psicose had an effect to suppress the postprandial blood glucose elevation mainly in borderline diabetes cases. A randomized double-blind placebo-controlled parallel-group experiment of long-term ingestion was conducted on 17 normal subjects who took 5 g of D-psicose or D-glucose with meals three times a day for 12 continuous weeks. Neither any abnormal effects nor clinical problems caused by the continuous ingestion of D-psicose were found.
