The ultimate effect of regular and diet carbonated soft drinks on energy intakes depends on possible relations with other dietary components. With this motivation, this study compared grocery purchase patterns of regular and diet soft drink consumers using a large sample of US single-person households. We tested for differences in food-spending shares allocated to 43 food categories chosen mainly for their desirable/undesirable nutritional properties. We also investigated whether differences in purchased quantity of diet soft drinks are associated with differences in purchases of other food categories. We found a large number of significant differences, virtually all showing that more diet soda prone consumers make better nutrition choices, particularly regarding energy content. The study suggests that use of diet soft drinks does not lead to compensation by increased use of high-energy foods.
常规碳酸软饮料和低糖碳酸软饮料对能量摄入的最终影响取决于它们与其他饮食成分之间可能存在的关系。出于这个动机，本研究使用美国大量单人家庭样本，比较了常规软饮料消费者和低糖软饮料消费者的食品购买模式。我们测试了分配给43种主要因其营养特性优劣而选择的食品类别的食品支出份额差异。我们还调查了低糖软饮料购买量的差异是否与其他食品类别的购买差异相关。我们发现了大量显著差异，几乎所有差异都表明，更倾向于饮用低糖汽水的消费者做出了更好的营养选择，尤其是在能量含量方面。该研究表明，饮用低糖软饮料不会导致通过增加高能量食品的摄入量来进行补偿。
