Nut consumption is associated with a range of health benefits. The current study aimed to examine nut consumption in the 2011-2012 National Nutrition and Physical Activity Survey (NNPAS) and to investigate associations between nut intake, nutrient intake and anthropometric and blood pressure measurements.
Secondary analysis of the 2011-2012 NNPAS. Usual consumption of nuts in the 2011-2012 NNPAS was determined, and nut consumption was compared with population recommendations of 30 g nuts per day. The relationship between nut consumption and intakes of key nutrients, anthropometric outcomes (weight, BMI and waist circumference) and blood pressure was examined using linear regression for participants aged over 18 years.
Australia.
Australians (2 years and older, n 12 153) participating in the representative 2011-2012 NNPAS.
Mean nut intake was 4·61 (95 % CI: 4·36, 4·86) g/d, with only 5·6 % of nut consumers consuming 30 g of nuts per day. Nut consumption was associated with significantly greater intakes of fibre, vitamin E, Fe, Mg and P. There was no association between nut consumption and body weight, BMI, waist circumference, or blood pressure.
Exploration of nut consumption in a representative sample of Australians identified that nut intake does not meet recommendations. Higher nut consumption was not adversely associated with higher body weight, aligning with the current evidence base. Given the current levels of nut consumption in Australia, strategies to increase nut intake to recommended levels are required.
坚果的摄入与多种健康益处相关。本研究旨在调查 2011-2012 年全国营养与身体活动调查（NNPAS）中的坚果摄入量，并探讨坚果摄入量与营养素摄入以及人体测量和血压测量指标之间的关联。
对 2011-2012 年 NNPAS 的二次分析。在 2011-2012 年 NNPAS 中确定坚果的日常摄入量，并将坚果摄入量与每日 30 克坚果的人群推荐摄入量进行比较。对于年龄在 18 岁及以上的参与者，采用线性回归方法研究坚果摄入量与关键营养素摄入、人体测量学指标（体重、BMI 和腰围）和血压之间的关系。
澳大利亚。
参与具有代表性的 2011-2012 年 NNPAS 的澳大利亚人（2 岁及以上，n 12 153）。
平均坚果摄入量为 4.61（95 % CI：4.36，4.86）g/d，只有 5.6 %的坚果消费者每天摄入 30 克坚果。坚果摄入量与膳食纤维、维生素 E、Fe、Mg 和 P 的摄入量显著增加相关。坚果摄入量与体重、BMI、腰围或血压之间没有关联。
对澳大利亚有代表性的样本中坚果摄入量的探索表明，坚果摄入量未达到推荐水平。较高的坚果摄入量与较高的体重没有不良关联，这与当前的证据基础一致。鉴于澳大利亚目前的坚果摄入量水平，需要采取策略来增加坚果摄入量至推荐水平。
