果糖的吸收代谢以及与健康的关系
果糖是一种单糖,由于其甜度大于葡萄糖和蔗糖,近年来高果糖浓度的果葡糖浆被广泛用于食品工业中。因此,近年来果糖对人体健康的影响备受关注。本研究总结了果糖的主要食物来源、吸收和代谢,与相关疾病之间的关系,以及推荐摄入量。果糖和葡萄糖不同,它的主要代谢器官是肝,除部分代谢为葡萄糖外,主要代谢为脂肪酸,后者进一步合成甘油三酯。肝中甘油三酯沉积会增加脂肪肝的发病风险和胰岛素抵抗,其余甘油三酯可被转运至其他组织器官,增加胰岛素抵抗、肥胖和心血管系统疾病的发病风险。世界卫生组织建议在整个生命历程中减少游离糖摄入量,成人和儿童游离糖摄入量应减至摄入总能量的10%以内。如能进一步将其降至低于摄入总能量的5%,则...

| Summary: | 果糖是一种单糖,由于其甜度大于葡萄糖和蔗糖,近年来高果糖浓度的果葡糖浆被广泛用于食品工业中。因此,近年来果糖对人体健康的影响备受关注。本研究总结了果糖的主要食物来源、吸收和代谢,与相关疾病之间的关系,以及推荐摄入量。果糖和葡萄糖不同,它的主要代谢器官是肝,除部分代谢为葡萄糖外,主要代谢为脂肪酸,后者进一步合成甘油三酯。肝中甘油三酯沉积会增加脂肪肝的发病风险和胰岛素抵抗,其余甘油三酯可被转运至其他组织器官,增加胰岛素抵抗、肥胖和心血管系统疾病的发病风险。世界卫生组织建议在整个生命历程中减少游离糖摄入量,成人和儿童游离糖摄入量应减至摄入总能量的10%以内。如能进一步将其降至低于摄入总能量的5%,则对健康有更多益处。 |

| Bibliography: | 33-1247/S fructose; insulin resistance; hypertension CAI Wenwen, LI Duo （Department of Food Science ＆ Nutrition, Zhejiang University, Hangzhou 310058, China ） Fructose is a monosaccharide,which is greatly sweeter than glucose and sucrose.In recent years,high fructose corn syrup has been widely used in beverages and food industry globally.However,the effect of fructose on human health has received much attention in current years.In this review,we mainly discussed the food source,absorption and metabolism of fructose,relationship between fructose and metabolic disorders,and recommendation intake of total sugar.Crystalline fructose is dried,ground,and highly pure.Fructose is found in most fruits and vegetables either as a monosaccharide or as a unit of sucrose.The ratio of fructose to glucose in most natural food is approximately 1∶1.Fructose has the lowest glycemic index of all natural sugars.High-fructose corn syrup（HFCS）is a mixture of fructose and glucose,which is widely used in food industry,added into soft dr |
