Regulatory changes in Canada will require food labels to have a benchmark [% Daily Value, %DV] for total sugars, based on 100 g/day, while US labels will require a %DV for added sugars, based on 50 g/day. The objective of this study was to compare two labelling policies, a total sugars DV (100 g/day) and a free sugars DV (50 g/day) on food labels. This cross-sectional analysis of the Food Label Information Program database focussed on top sources of total sugars intake in Canada (n = 6924 foods). Products were categorized as "less healthy" using two sets of criteria: a) free sugars levels exceeding the WHO guidelines (≥10% energy from free sugars); and b) exceeding healthfulness cut-offs of the Food Standards Australia New Zealand Nutrient Profiling Scoring Criterion (FSANZ-NPSC). The proportion of "less healthy" products with ≥15%DV (defined as "a lot" of sugars i.e. high in sugars, based on Health Canada's %DV labelling footnote and educational message for dietary guidance) were compared for each sugar labelling scenario. The free sugars DV showed better alignment with both methods for assessing "healthfulness" than the total sugars DV. The free sugars DV identified a greater proportion of "less healthy" foods with ≥15%DV, based on both the FSANZ-NPSC (70% vs. 45%, p < .0001) and WHO guidelines (82% vs. 55%, p < .0001); particularly in sweet baked goods, sugars and preserves, chocolate bars, confectionery, and frozen desserts categories. Compared to total sugars DV labelling, using a free sugars DV identified more "less healthy" foods. Findings support the adoption of free sugars labelling.
加拿大的法规变化将要求食品标签标明基于每日100克摄入量的总糖基准[每日营养素参考值百分比，%DV]，而美国标签则要求标明基于每日50克摄入量的添加糖%DV。本研究的目的是比较食品标签上的两种标签政策，即总糖DV（每日100克）和游离糖DV（每日50克）。这项对食品标签信息计划数据库的横断面分析聚焦于加拿大总糖摄入量的主要来源（n = 6924种食品）。使用两组标准将产品归类为 “不太健康”：a）游离糖水平超过世界卫生组织指南（游离糖提供的能量≥10%）；b）超过澳大利亚新西兰食品标准局营养成分剖析评分标准（FSANZ-NPSC）的健康度临界值。针对每种糖标签方案，比较了游离糖含量≥15%DV（根据加拿大卫生部的%DV标签脚注和饮食指导教育信息，定义为 “大量” 糖，即含糖量高）的 “不太健康” 产品的比例。与总糖DV相比，游离糖DV在评估 “健康度” 的两种方法上都表现出更好的一致性。基于FSANZ-NPSC（70% 对45%，p <.0001）和世界卫生组织指南（82% 对55%，p <.0001），游离糖DV识别出更高比例的游离糖含量≥15%DV的 “不太健康” 食品；特别是在甜烘焙食品、糖类和蜜饯、巧克力棒、糖果及冷冻甜点类别中。与总糖DV标签相比，使用游离糖DV能识别出更多 “不太健康” 的食品。研究结果支持采用游离糖标签。
