Despite considerable evidence supporting the health benefits of regular nut consumption, nut intakes remain lower than recommended among many populations. Understanding how the general population perceives nuts could inform strategies to promote regular nut consumption and increase intakes among the general public.
Cross-sectional study. Participants were invited to complete a questionnaire which included information on nut consumption and knowledge and perceptions of nuts.
The study was set in New Zealand (NZ).
Participants (n 1600), aged 18 years or over, were randomly selected from the NZ electoral roll.
A total of 710 participants completed the questionnaire (response rate 44 %). More than half of the respondents believed that nuts are healthy, filling, high in protein and high in fat. The most common reason cited by consumers for eating nuts was taste (86 % for nuts, 85 % for nut butters), while dental issues was the most frequent reason for avoidance. About 40 % of respondents were not aware of the effects of nut consumption on lowering blood cholesterol and CVD risk.
Despite overall basic knowledge of the nutritional value of nuts, a substantial proportion of the general population was unaware of the cardioprotective effects of nuts. The present study identified common motivations for eating and avoiding nuts, as well as perceptions of nuts which could affect intake. These should guide the content and direction of public health messages to increase regular nut consumption. The public's knowledge gaps should also be addressed.
尽管有大量证据表明经常食用坚果有益健康，但在许多人群中，坚果的摄入量仍低于建议量。了解一般人群如何看待坚果，可以为促进人们经常食用坚果和增加普通公众摄入量的策略提供信息。
横断面研究。邀请参与者完成一份问卷，其中包括关于坚果消费以及对坚果的知识和看法的信息。
该研究在新西兰（NZ）进行。
年龄在 18 岁或以上的受试者从 NZ 选民名单中随机抽取，共 1600 名。
共有 710 名参与者完成了问卷（应答率 44%）。超过一半的受访者认为坚果是健康的、有饱腹感的、富含蛋白质和脂肪。消费者食用坚果的最常见原因是味道（坚果为 86%，坚果酱为 85%），而避免食用坚果的最常见原因是牙齿问题。约 40%的受访者不知道食用坚果对降低血液胆固醇和 CVD 风险的影响。
尽管人们对坚果的营养价值有总体上的基本认识，但相当一部分普通人群并不知道坚果对心脏有保护作用。本研究确定了食用和避免食用坚果的常见动机，以及可能影响摄入量的坚果看法。这些应该指导公共卫生信息的内容和方向，以增加人们经常食用坚果。还应解决公众的知识差距。
