学校沙拉吧被广泛推广，作为一种手段，以提高遵守国家学校午餐计划（NSLP）的营养任务。然而，目前尚不清楚如何沙拉吧或水果和蔬菜（F&V）的摄入量与NSLP内的能量摄入量有关，或者F& V是否取代了其他来源的能量。这种关系对于了解来自少数民族背景的儿童尤其重要，因为他们面临肥胖和粮食不安全的高风险，并且最有可能受到学校食品政策的影响，因为他们依赖学校膳食。这项研究的目的是评估学校沙拉吧和F&V摄入量是否与午餐能量摄入量降低有关。在弗吉尼亚州的小学有和没有沙拉吧，和F&V能源和其他能源之间的关联，能量摄入进行了检查。在匹配的学校对中进行了横断面盘子浪费评估（3个有沙拉吧，3个没有沙拉吧; N = 1，102名学生; >90%黑人和拉丁裔; 100%免费餐）。两级分层模型评估组之间的差异，能量摄入量和能量的比例，从每餐组成部分。平均午餐总能量摄入量为304 ± 157千卡（沙拉吧）; 269 ± 152千卡（无沙拉吧）。沙拉吧学校的学生从蔬菜中消耗更多的能量（+11千卡; P < .001）。能量摄入模式不一致的对。F&V能量与非F &V能量无关（F = 1.04，P = .31）。研究结果并不表明沙拉吧与较低的能量摄入有关。关于F&V替代其他午餐热量的证据不一致。需要进一步研究F&V，沙拉吧和能量摄入。
School salad bars are widely promoted as a means to increase adherence to National School Lunch Program (NSLP) nutrition mandates. Yet it is unknown how salad bars or fruit and vegetable (F&V) intake relates to energy intake within the NSLP, or if F&Vs displace energy from other sources. This relation is particularly important to understand among children from minoritized backgrounds, who are at high risk of obesity and food insecurity, and the most likely to be impacted by school food policies, given their reliance on school meals. This study purpose was to evaluate if school salad bars and F&V intake are associated with lower lunch energy intake. Energy intake in Virginia elementary schools with and without salad bars, and associations between F&V energy and other energy sources, were examined. Cross-sectional plate waste assessments were conducted in matched school pairs (3 with, 3 without salad bars; N = 1,102 students; >90% Black and Latinx; 100% free meals). Two-level hierarchical models assessed group differences in energy intake and the proportion of energy from each meal component. Mean total lunch energy intake was 304 ± 157 kcal (salad bar); 269 ± 152 kcal (no salad bar). Students in salad bar schools consumed more energy from vegetables (+11 kcal; P < .001). Energy intake patterns were inconsistent across pairs. F&V energy was not associated with non-F&V energy (F = 1.04, P = .31). Findings do not suggest that salad bars were associated with lower energy intake. Evidence was inconsistent regarding F&V displacement of other lunch calories. Further research regarding F&V, salad bars, and energy intake is needed.
