摘　　要：近年来,与医学相关的营养与代谢的研究出现不少新的认识与新发现。本文总结了以下5个方面的新概念:供能的营养物质不仅是供能,还需注意他们对健康的影响;以构成蔗糖分子一半的果糖为例,它竟然是促成代谢综合征、心脑血管病等疾病的因素;食物纤维是极其重要不可或缺的营养素;应高度重视维护正常肠道菌群,因为它与人体的健康与多种疾病密切相关;全食物营养不仅能维持生命,还能增强体质、避免和减少疾病;植物营养素具有抗氧化、抗炎症及抗癌等作用,是全食物营养不可或缺的组成部分。人体营养与物质代谢研究的终极目标是:增强体质,预防和减少疾病,健康长寿。希望本文能够带给读者一些启发。Based on the clinical research in recent years,this article summarized a few new concepts of nutrition and metabolism.Firstly,besides the traditional calorie calculation,different dietary nutrients have different,either positive or negative,impact to health.For example,the fructose component in sucrose plays critical roles in the development of cardiometabolic syndrome and cardiovascular disease.Secondly,besides the beneficial antioxidants,anti-inflammation and anticancer effects,phytochemicals play an important and unreplaceable role in whole food nutrition.Thirdly,Food fiber plays special roles in human nutrition.Fourthly,keep the balance of gut microbiota is another key point to avoid diseases such as obesity,depression,and Parkinson’s disease.Finally,the ideal whole food nutrition should not only help to keep the human body alive but also maintain energetic and protect from different damage.
