REGULATION OF ACCUMULATTION AND COMBUSTION OF BODY FAT BY FOOD.REGULATION OF LIPID METABOLISM BY FOOD

1)研究了维生素K_5对3T3-L1细胞前脂肪细胞生长速度和前脂肪细胞向脂肪细胞的终末分化的影响。2)研究了生姜对人体体表温度、血压和血流的影响。生姜在10min时提高了额头、手臂和颈部的表面温度。3)研究了红辣椒对人体运动过程中能量代谢的影响，发现少量摄入红辣椒能促进脂代谢，但减少儿茶酚胺的分泌。4)研究了香蕉和大米对人体脂代谢的影响。摄入碳水化合物诱导胰岛素的分泌，控制能量代谢；香蕉和大米控制胰岛素的分泌，刺激脂肪组织的脂肪代谢。

1) The effects of Vitamin K_5 on the growth rate of preadipocytes and the terminal differentiation of preadipocytes to adipocytes were investigated in 3T3-L1 celLs.The vitaminK_5 inhibited the conversion of 3T3-L1 preadipocytes to adipocytes and stimulated TG accumulation.2) The effects of ginger on body surface temperature, blood pressure and bloodstream In human were studied. Ginger raised the surface temperature of the forehead, arm and neck at 10min. after the ingestion and this effects continued more than 30min, and Ginger reduced blood pressure and decreased bloodstream.3) Effects of red pepper on the energy metabolism in human during exercise were studied.The small intake of red pepper stimulated lipid metabolism, but decreased the secretion of catecholamine.4) Effects of banana and rice on the lipid metabolism in human were investigated. Intake of carbohydrate induced the secretion of insulin , which controlled energy metabolism.Banana and rice controlled the insulin secretion and stimulated lipid metabolism from adipose tissue.
