To assess the Na content reported on the labels of processed foods sold in Brazil that are usually consumed as snacks by children and adolescents.
Cross-sectional study that assessed Na content and serving size reporting on processed food labels.
A supermarket that is part of a large chain in Brazil.
All foods available for sale at the study's location and reported in the literature as snacks present in the diets of Brazilian children and adolescents.
Of the 2945 processed foods, 87 % complied with the reference serving sizes, although variability in reporting was observed in most of the food subgroups. In addition, 21 % of the processed foods had high Na levels (>600 mg/100 g) and 35 % had medium Na levels (>120 and ≤600 mg/100 g). The meats, oils, fats and seeds groups as well as the prepared dishes had higher percentages of foods classified as high Na (81 %, 58 % and 53 %, respectively).
Most of the processed foods had high or medium Na content. We emphasize the importance of revising Brazilian nutrition labelling legislation to standardize reference serving sizes to avoid variation. Besides, we point out the potential for reducing Na levels in most processed foods, as evidenced by the variability in Na content within subgroups. Finally, we have identified the need to develop a method to classify Na levels in processed foods with specific parameters for children and adolescents.
评估在巴西销售的通常被儿童和青少年当作零食食用的加工食品标签上标注的钠含量。
一项横断面研究，评估加工食品标签上的钠含量及食用份量标注情况。
巴西一家大型连锁超市中的一家分店。
研究地点在售的所有食品，以及文献中报道的巴西儿童和青少年饮食中作为零食的食品。
在2945种加工食品中，87%符合参考食用份量标准，不过在大多数食品亚组中都观察到了标注的差异。此外，21%的加工食品钠含量高（>600毫克/100克），35%的加工食品钠含量中等（>120且≤600毫克/100克）。肉类、油类、脂肪和种子类食品以及预制菜肴中被归类为高钠食品的比例更高（分别为81%、58%和53%）。
大多数加工食品钠含量高或中等。我们强调修订巴西营养标签法规以规范参考食用份量从而避免差异的重要性。此外，我们指出大多数加工食品有降低钠含量的潜力，亚组内钠含量的差异就证明了这一点。最后，我们确定需要制定一种方法，用针对儿童和青少年的特定参数对加工食品中的钠含量进行分类。
