Pork represents a core food that provides key nutrients to the diet. Dietary guidelines recommend limiting processed meat intake because of adverse health outcomes. The aims of this study were to describe pork consumption, assess the contribution of pork to nutrient intakes, and compare anthropometric characteristics between pork consumers and nonconsumers in a survey of Australian children. We hypothesized that pork consumption will contribute to intakes of key nutrients and that the weight status of children who consume pork will be similar to nonconsumers. This study involved a secondary analysis of the 2007 Australian National Children's Nutrition and Physical Activity Survey. Pork and pork-containing dishes were identified and classified as fresh or processed pork. The contributions of pork to nutrient intakes were calculated. Weight, waist circumference, and body mass index were compared between pork consumers and nonconsumers. Data from 4487 children were available for use. Of this sample, 2245 reported consuming pork, 14% (n = 310) of whom consumed fresh pork, whereas 93% (n = 2084) consumed processed pork. All types of pork contributed to intakes of protein, niacin, and zinc. In addition, fresh pork contributed to intakes of thiamine, long-chain omega-3, phosphorous, and potassium. Total and processed pork contributed 12.2% and 13.0% of sodium, respectively. There were no significant differences between weight, waist circumference, and body mass index in consumers and nonconsumers of total, fresh, or processed pork. In a survey of Australian children, processed pork was the most frequently consumed form of pork, suggesting a deviation from dietary guidelines.
猪肉是一种核心食物,为饮食提供了关键营养。饮食指南建议限制加工肉类的摄入量,因为这会对健康产生不利影响。本研究的目的是描述猪肉的消费情况,评估猪肉对营养素摄入量的贡献,并在对澳大利亚儿童的调查中比较猪肉消费者和非消费者的人体测量特征。我们假设猪肉的消费将有助于关键营养素的摄入,并且食用猪肉的儿童的体重状况将与非消费者相似。本研究是对 2007 年澳大利亚国家儿童营养和身体活动调查的二次分析。确定并分类了新鲜或加工猪肉的猪肉和含猪肉菜肴。计算了猪肉对营养素摄入量的贡献。比较了猪肉消费者和非消费者的体重、腰围和体重指数。共有 4487 名儿童的数据可供使用。在这个样本中,有 2245 人报告食用猪肉,其中 14%(n = 310)食用新鲜猪肉,而 93%(n = 2084)食用加工猪肉。所有类型的猪肉都有助于蛋白质、烟酸和锌的摄入。此外,新鲜猪肉有助于摄入硫胺素、长链欧米伽-3、磷和钾。新鲜猪肉和加工猪肉分别提供了 12.2%和 13.0%的钠。在总猪肉、新鲜猪肉和加工猪肉的消费者和非消费者之间,体重、腰围和体重指数没有显著差异。在对澳大利亚儿童的调查中,加工猪肉是最常消费的猪肉形式,这表明人们偏离了饮食指南。
