Regular nut consumption is associated with reduced CVD risk. Insight into nut consumption patterns provides important information to help design strategies to encourage intake. The present study aimed to describe nut consumption in terms of the percentage of consumers, mean grams eaten among the population and nut consumers, and to identify the predictors of nut consumption. Data from the 24 h dietary recalls of the 2008/09 New Zealand Adult Nutrition Survey (n 4721) were used to measure nut consumption. On the recall day, the percentages of consumers of whole nuts, nut butters and nuts from hidden sources were 6.9% (n 240), 7.2% (n 346) and 19.2% (n 732), respectively (28.9% (n 1167) combined (total)). The mean grams consumed by the population were relatively low for whole nuts (2.8 g/d), nut butters (0.9 g/d), nuts from hidden sources (1.5 g/d) and total nuts (5.2 g/d). Among consumers, the mean daily grams of whole nuts, nut butters, nuts from hidden sources and total nuts eaten were 40.3, 12.9, 7.8 and 17.9 g/d, respectively. Those aged 15-18 years had the lowest whole nut consumption, but had the highest nut butter consumption. The consumption of total nuts was positively associated with education and socio-economic status, while whole nut consumption was inversely associated with BMI. In conclusion, the low percentage of nut consumers is of concern and new strategies to increase nut consumption are required. Future public health initiatives should be mindful of these patterns and predictors. In particular, different forms of nuts may appeal to different age and socio-economic groups.
经常食用坚果与降低心血管疾病风险相关。了解坚果消费模式可为制定鼓励摄入的策略提供重要信息。本研究旨在从消费者比例、人群及坚果消费者的平均食用克数方面描述坚果消费情况,并确定坚果消费的预测因素。采用2008/09年新西兰成人营养调查(n = 4721)24小时饮食回顾的数据来衡量坚果消费情况。在回顾日,食用全坚果、坚果酱和隐藏来源坚果的消费者比例分别为6.9%(n = 240)、7.2%(n = 346)和19.2%(n = 732)(总计28.9%(n = 1167))。人群食用全坚果(2.8克/天)、坚果酱(0.9克/天)、隐藏来源坚果(1.5克/天)和总坚果(5.2克/天)的平均克数相对较低。在消费者中,全坚果、坚果酱、隐藏来源坚果和总坚果的平均每日食用克数分别为40.3、12.9、7.8和17.9克/天。15 - 18岁人群的全坚果消费量最低,但坚果酱消费量最高。总坚果消费与教育程度和社会经济地位呈正相关,而全坚果消费与体重指数呈负相关。总之,坚果消费者比例较低令人担忧,需要采取新策略来增加坚果消费。未来的公共卫生举措应关注这些模式和预测因素。特别是,不同形式的坚果可能对不同年龄和社会经济群体有吸引力。
