Processed food is associated with unhealthy qualities such as higher content of harmful fats, sugars and salt. The aim of our study was to compare the nutritional qualities of supermarket's own brands and regular brands of bread sold in Sweden. Additionally, we compared the nutritional qualities of gluten-free and gluten-containing bread. We collected information from the labels of 332 bread products available in the largest grocery store chains. The Australian Health Star Rating (HSR) system was used to quantify the nutritional quality of each bread product. We compared all supermarket's own brand products to regular brand products, and gluten-free to gluten-containing bread. The mean HSR for the supermarket's own brands was lower than the regular brands (3.6 vs. 3.7; = 0.046). For the regular brand products, the fibre, sugar and total fat content were greater ( < 0.001, = 0.002 and = 0.021, respectively), while less protein ( = 0.009) compared to regular bread products. Gluten-free bread had a lower HSR than gluten-containing bread (mean 3.5 vs. 3.8, respectively; < 0.001). The regular brand products were slightly healthier than the supermarket's own brands, primarily as a result of a higher fibre content. Gluten-free bread products were slightly unhealthier due to a lower protein content.
加工食品通常含有较高的有害脂肪、糖和盐，与不健康有关。我们的研究旨在比较瑞典超市自有品牌和常规品牌面包的营养品质。此外，我们还比较了无麸质和含麸质面包的营养品质。我们从最大的连锁杂货店中 332 种面包产品的标签上收集信息。我们使用澳大利亚健康星级评级（HSR）系统来量化每种面包产品的营养质量。我们将所有超市自有品牌产品与常规品牌产品进行比较，以及无麸质面包与含麸质面包进行比较。超市自有品牌的平均 HSR 低于常规品牌（3.6 对 3.7； = 0.046）。对于常规品牌产品，纤维、糖和总脂肪含量更高（<0.001， = 0.002 和 = 0.021，分别），而蛋白质含量较低（ = 0.009），与常规面包产品相比。无麸质面包的 HSR 低于含麸质面包（平均值 3.5 对 3.8； < 0.001）。常规品牌产品比超市自有品牌产品略健康，主要是由于纤维含量较高。由于蛋白质含量较低，无麸质面包产品略不健康。
