《營養與代謝》是一本開放獲取、同行評議的在線期刊，專注于營養、運動生理學、臨床研究、代謝分子和細胞生物化學的整合。營養與代謝的研究領域包括肥胖、糖尿病、血脂、代謝綜合征和運動生理學，這些都是新陳代謝的基礎。同樣，我們也希望提交關于代謝生物化學、細胞信號、營養分子和細胞生物學、營養基因相互作用以及其他對人類營養和醫學有意義的領域的手稿。目前，但并非唯一的興趣是飲食組成的代謝作用，大量營養素的相互作用，營養物質對基因表達的影響，代謝控制和室室模型，激素的營養作用，飲食現象的基因組分析。最近的事件提供營養和新陳代謝的理由是1)肥胖流行病的認識,糖尿病、脂血和其他相關疾病,2)突然增加流行的飲食,如低碳水化合物的飲食,達到減肥目的,和3)興趣重燃中間代謝的發展伴隨著基因組和代謝分析的新工具和技術。由于這些領域的大量活動，迅速傳播新的資料顯然是有價值的。現有期刊上發表的文章討論的是營養背景下的中介代謝，而這門學科需要獨特而明確的重點。

Nutrition & Metabolism is an open access, peer-reviewed, online journal focused on the integration of nutrition, exercise physiology, clinical investigations, and molecular and cellular biochemistry of metabolism. The areas of interest of Nutrition & Metabolism encompass studies in obesity, diabetes, lipidemias, metabolic syndrome and exercise physiology that have an underlying basis in metabolism. Likewise, we seek submission of manuscripts on the biochemistry of metabolism, cell signaling, molecular and cellular biology of nutrients, nutrient gene interactions and other areas that have implications for human nutrition and medicine. Current, but not exclusive, interests are metabolic effects of diet composition, interactions of macronutrients, effect of nutrients on gene expression, metabolic control and compartment models, nutritional effect of hormones, and genomic analysis of dietary phenomena. Recent events that provide the rationale for Nutrition & Metabolism are 1) awareness of an epidemic of obesity, diabetes, lipidemias and other related diseases, 2) the sudden increase in popularity of diets, such as low carbohydrate diets, to achieve weight loss, and 3) a renewed interest in intermediary metabolism accompanied by the development of new tools and techniques for genomic and metabolic analysis. With the considerable activity shown in these areas, rapid dissemination of new information is clearly valuable. Whereas articles that appear in existing journals discuss intermediary metabolism in a nutritional context, there is a need for unique and explicit focus for this discipline.
