■乳糜泻是在遗传易感个体中由麸质暴露引发的慢性自身免疫性疾病。其管理需要终身摄入无麸质(GF)饮食。小麦,黑麦和大麦在GF饮食中被淘汰,饮食的营养充足性受到质疑。在挪威,谷物和面包构成了饮食的关键作用,是纤维摄入的主要来源。因此,麸质限制可能对营养充足性提供重要影响,尤其是与乳糜泻患者的纤维摄入量有关。
■该研究的目的是调查GF产品的营养质量和价格,并与挪威市场上的含麸质产品进行比较。
■将423种独特的GF产品的大量营养素含量与337当量的面筋进行了比较。所有产品都是从杂货店和基于网络的商店中选择的,目的是包括尽可能多的GF产品。通过Wilcoxon符号秩检验,将11种不同食品类别中列出的大量营养素含量和价格与含麸质的对应物进行了比较。
■GF产品含有较少的蛋白质和纤维,和更高的饱和脂肪含量,与含麸质产品相比,碳水化合物和盐。两组之间的脂肪总量没有差异。在几种食物类别中发现了类似的模式。与GF产品相比,更多的含麸质产品符合“高纤维”(纤维>6g/100g)的营养要求。GF产品的价格更高;比含有麸质的产品贵46%-443%。
■GF产品与同等含麸质产品相比,营养较少,价格较高。知道不健康的饮食是发展非传染性疾病的最重要危险因素,GF饮食的营养质量需要解决,应该提高。
UNASSIGNED: Celiac disease is a chronic autoimmune disease triggered by gluten exposure in genetically predisposed individuals. A life-long intake of a gluten-free (GF) diet is required for its management. Wheat, rye and barley are eliminated in a GF diet and the nutritional adequacy of the diet has been questioned. In Norway, cereals and bread constitute a key role of the diet and are the main source of
fiber intake. Gluten restrictions may therefore offer important implications for nutrient adequacy especially linked to
fiber intake in people with celiac disease.
UNASSIGNED: The aim of the study was to investigate the nutritional quality and price of GF products and compare with gluten-containing counterparts available at instead of in the Norwegian market.
UNASSIGNED: The macronutrient content of 423 unique GF products were compared with 337 equivalents with gluten. All products were selected from grocery stores and web-based shops, with the aim of including as many GF products as possible. Listed macronutrients content and price in 11 different food categories were compared to gluten-containing counterparts with Wilcoxon signed rank test.
UNASSIGNED: The GF products contained less protein and
fiber, and higher content of saturated fat, carbohydrate and salt compared to the gluten-containing products. The total amount of fat was not different between the groups. A similar pattern was found within several of the food categories. More gluten-containing products met the nutrition claim \"high in
fiber\" (
fiber > 6 g/100 g) compared to the GF products. The price of the GF products was higher; ranging from 46%-443% more expensive than the gluten-containing products.
UNASSIGNED: GF products are less nutritious and have a higher price compared to equivalent gluten-containing products. Knowing that an unhealthy diet is the most important risk factor for developing non-communicable diseases, the nutritional quality of a GF diet needs to be addressed and should be improved.
