Apart from meeting daily protein requirements, an even distribution of protein consumption is proposed instrumental to optimizing protein muscle synthesis and preserving muscle mass. We assessed whether a high frequency protein-rich meal service for three weeks contributes to an even daily protein distribution and a higher muscle function in pre-operative patients. This study was a post-hoc analysis of a randomized controlled trial (RCT) in 102 patients. The intervention comprised six protein-rich dishes per day. Daily protein distribution was evaluated by a three-day food diary and muscle function by handgrip strength before and after the intervention. Protein intake was significantly higher in the intervention group at the in-between meals in the morning (7 ± 2 grams (g) vs. 2 ± 3 g, < 0.05) and afternoon (8 ± 3 g vs. 2 ± 3 g, < 0.05). Participants who consumed 20 g protein for at least two meals had a significantly higher handgrip strength compared to participants who did not. A high frequency protein-rich meal service is an effective strategy to optimize an even protein distribution across meals throughout the day. Home-delivered meal services can be optimized by offering more protein-rich options such as dairy or protein supplementation at breakfast, lunch and prior to sleep for a better protein distribution.
除了满足日常蛋白质需求外，建议均匀分配蛋白质摄入，以优化蛋白质肌肉合成和维持肌肉量。我们评估了高蛋白餐服务持续三周是否有助于均匀分配每日蛋白质，并提高术前患者的肌肉功能。本研究是一项 102 例患者的随机对照试验（RCT）的事后分析。干预措施包括每天六份富含蛋白质的菜肴。通过三天的食物日记评估每日蛋白质分布，通过干预前后握力评估肌肉功能。干预组在早餐和下午的加餐中蛋白质摄入量明显更高（7 ± 2 克（g）vs. 2 ± 3 g，< 0.05）和下午（8 ± 3 g vs. 2 ± 3 g，< 0.05）。与未摄入 20 克蛋白质至少两餐的参与者相比，摄入 20 克蛋白质至少两餐的参与者握力明显更高。高频率富含蛋白质的膳食服务是优化全天各餐中均匀蛋白质分布的有效策略。通过在早餐、午餐和睡前提供更多富含蛋白质的选择，如乳制品或蛋白质补充剂，可以优化家庭送餐服务，以实现更好的蛋白质分布。
