We classified a nationally representative sample of persons aged 4 years and older as high or moderate consumers of added sugars (ie, sugars added to foods by processors or consumers). Intake of added sugars was determined on the basis of grams consumed per kilogram of body weight (g/kg) and on the basis of percent of dietary energy from added sugars (% kcal). Regardless of the intake measure used, high consumers of added sugars had a significantly lower percentage of dietary energy from fat than did moderate consumers of added sugars. Persons defined by the % kcal measure as high consumers of added sugars took in lower percentages of the Recommended Dietary Allowances (RDAs) for 11 vitamins and minerals; these high consumers had body weights similar to those of their moderate counterparts. Persons defined as high consumers by the g/kg measure consumed greater percentages of the RDAs than did their moderate counterparts; these high consumers more frequently selected foods from categories likely to contain sugar-rich foods but weighed significantly less than did moderate consumers. Thus, different approaches to defining intake of added sugars revealed two patterns of high consumption of added sugars with different levels of nutritional risk. Conditions of overweight were not associated with high intake of added sugars. Educational efforts, therefore, should focus on those consumers who tend to substitute foods rich in added sugars for more nutritionally desirable foods.
我们将一个具有全国代表性的4岁及以上人群样本分为添加糖的高消费者或中度消费者(即由食品加工商或消费者添加到食品中的糖)。添加糖的摄入量是根据每千克体重摄入的克数(g/kg)以及添加糖占膳食能量的百分比(%千卡)来确定的。无论采用何种摄入量衡量标准,添加糖的高消费者从脂肪中获取的膳食能量百分比均显著低于添加糖的中度消费者。按%千卡衡量标准被定义为添加糖高消费者的人群,其11种维生素和矿物质的摄入量占推荐膳食摄入量(RDA)的百分比更低;这些高消费者的体重与中度消费者相似。按g/kg衡量标准被定义为高消费者的人群,其摄入量占RDA的百分比高于中度消费者;这些高消费者更频繁地从可能含有高糖食物的类别中选择食物,但体重明显低于中度消费者。因此,定义添加糖摄入量的不同方法揭示了两种不同营养风险水平的添加糖高消费模式。超重情况与添加糖的高摄入量无关。因此,教育工作应关注那些倾向于用富含添加糖的食物替代更具营养优势食物的消费者。
