The aim of the current study was to investigate the association between diet and handgrip strength. The current study included 68,002 participants (age 63.8 ± 2.7 years, 50.3% women, 49.7% men) from UK Biobank. Diet and nutritional data (carotene, retinol, potassium, vitamin C, foliate, vitamin B12, vitamin B6, iron, vitamin E, calcium, magnesium, carbohydrates, protein, polyunsaturated fat, fat, starch and saturated fat) were collected and handgrip strength measured. Associations were compared, stratified by sex, using regression analyses, after adjustment for age, sex, month of assessment, ethnicity, deprivation index, height, comorbidities and total energy intake. The current data revealed negative associations between carbohydrate intake and handgrip strength as well as positive associations between oily fish, retinol and magnesium intake and grip strength in both sexes. In women, positive associations were observed between intake of red meat, fruit and vegetables, vitamin E, iron, vitamin B12, folate and vitamin C and hand grip strength. In men only negative associations were seen between bread and processed meat with grip strength. We have shown associations of several nutrients and food items with muscle strength and appropriately designed trials are needed to investigate whether these nutrients/food items may be beneficial in the maintenance of muscle during ageing.

本研究的目的是研究饮食与握力之间的关系。本研究包括UK Biobank的68,002名参与者（年龄63.8±2.7岁，女性50.3％，男性49.7％）。收集饮食和营养数据（胡萝卜素，视黄醇，钾，维生素C，叶酸，维生素B12，维生素B6，铁，维生素E，钙，镁，碳水化合物，蛋白质，多不饱和脂肪，脂肪，淀粉和饱和脂肪）并掌握握力测量。在对年龄，性别，评估月份，种族，贫困指数，身高，合并症和总能量摄入进行调整后，使用回归分析对协会进行了比较，并按性别进行了分层。当前数据显示碳水化合物摄入量和握力之间呈负相关，而油性鱼之间呈正相关，视黄醇和镁的摄入量和男女的握力。在女性中，红肉，水果和蔬菜，维生素E，铁，维生素B12，叶酸和维生素C的摄取与握力之间存在正相关。在男性中，只有面包和加工后的肉之间的负相关性与握力有关。我们已经显示出几种营养物质和食物与肌肉力量之间的联系，需要进行适当设计的试验来研究这些营养物质/食物在衰老过程中是否对维持肌肉有益。在男性中，只有面包和加工后的肉之间的负相关性与握力有关。我们已经显示出几种营养物质和食物与肌肉力量之间的联系，需要进行适当设计的试验来研究这些营养物质/食物在衰老过程中是否对维持肌肉有益。在男性中，只有面包和加工后的肉之间的负相关性与握力有关。我们已经显示出几种营养物质和食物与肌肉力量之间的联系，需要进行适当设计的试验来研究这些营养物质/食物在衰老过程中是否对维持肌肉有益。
