    Diacylglycerol (DAG) is a unique fat that shows unexpected health benefits such as a reduction of body fat in spite of the energy value equivalent to that of the corresponding triacylglycerol. This effect can at least in part be attributed to its absorption characteristics, but the working mechanism is not fully disclosed yet. In addition, when plant sterols were dissolved in DAG, there is a marked stimulation of their hypocholesterolemic activity. Thus, a sophisticated dietary application of DAG may reduce the risk of life style-related disease, a serious social problem nationwide.

  • Physiological Effects and Safety of Plant Sterols

    A lot of basic and clinical researchers with plant sterols have been conducted after the discovery of lowering effect of blood cholesterol by plant sterols in the 1950s. Based on these abundant research results, the foods added plant sterols have been commercially developed in Japan and Western countries. Various results on the physiological effects and safety of plant sterols have been reported, meanwhile the reports on a different interpretation from the past recognition have also appeared recently. The latest knowledge of physiological effects and safety of plant sterols were summarized in this review.

  • Nutritional Studies on Medium-Chain Fatty Acid
    From the Recent Research
    Toshiaki AOYAMA
    2003 Volume 3 Issue 8 Pages 403-410,386

    Medium-chain fatty acids (MCFA), differing from long-chain fatty acids (LCFA) in ordinary oils and fats, are absorbed into portal vein and directly transported to the liver for rapid oxidation. Therefore, MCFA lead to higher diet-induced thermogenesis. MCFA hardly raise postprandial plasma triglyceride. MCFA have been confirmed to be safe under normal conditions. Recently, long-term clinical trials have demonstrated that medium-chain triacylglycerols (MCT) and medium and long-chain triacylglycerols (MLCT) result in less body fat. Despite a relatively low proportion of MCFA, MLCT are effective for reducing body fat, and available for multi purpose edible oils.
