This study examined the serving size and energy content per serving of Australian packaged snack foods and confectionery products. Nutrition Information Panel data for 23 sub-categories of packaged snack foods (n = 3481) were extracted from The George Institute for Global Health's 2013 branded food composition database. Variations in serving size and energy content per serving were examined. Energy contents per serving were compared to recommendations in the Australian Dietary Guidelines. Serving sizes varied within and between snack food categories. Mean energy content per serving varied from 320 kJ to 899 kJ. More energy per serving than the recommended 600 kJ was displayed by 22% (n = 539) of snack foods classified in the Australian Dietary Guidelines as discretionary foods. The recommendation for energy content per serving was exceeded in 60% (n = 635) of snack foods from the Five Food Groups. Only 37% (n = 377) of confectionery products displayed the industry-agreed serving size of 25 g. Energy content per serving of many packaged snack foods do not align with the Australian Dietary Guidelines and the industry agreed serving size has not been taken up widely within the confectionery category. Given the inconsistencies in serving sizes, featuring serving size in front-of-pack information may hinder the objective of a clear and simple nutrition message. Messaging to help consumers make healthier choices should consider the variation in serving sizes on packaged snack foods.
本研究调查了澳大利亚包装零食和糖果产品的份量和每份的能量含量。从乔治全球健康研究所 2013 年的品牌食品成分数据库中提取了 23 个包装零食亚类（n=3481）的营养信息面板数据。研究检查了份量和每份能量含量的变化。将每份的能量含量与澳大利亚膳食指南的建议进行了比较。零食类别内和类别之间的份量大小存在差异。每份的平均能量含量从 320kJ 到 899kJ 不等。在被澳大利亚膳食指南归类为随意食品的 22%（n=539）的零食中，有 22%（n=539）显示每份的能量含量超过了推荐的 600kJ。在来自五个食物组的 60%（n=635）的零食中，超过了推荐的每份能量含量。只有 37%（n=377）的糖果产品显示出行业协议的 25g 份量。许多包装零食的每份能量含量与澳大利亚膳食指南不符，并且行业协议的份量大小在糖果类别中并未得到广泛采用。鉴于份量大小的不一致性，在包装食品的正面信息中突出份量可能会阻碍清晰简洁的营养信息传递的目标。为帮助消费者做出更健康的选择而传递的信息应考虑包装零食份量大小的变化。
