Eating plenty of vegetables and fruits on a daily basis is the foundation of a healthy diet. This study investigated patterns in Canadians' vegetable and fruit consumption in 2015 and compared these with 2004 data.
The 2015 Canadian Community Health Survey (CCHS) - Nutrition and the 2004 CCHS - Nutrition (Cycle 2.2) provided nationally representative 24-hour dietary recall data on Canadians' vegetable and fruit intakes. The frequency of consumption and the average quantity of daily intake for total vegetables, fruits and subgroups were calculated overall and by age and sex group for each survey year. The National Cancer Institute's methodology was used to assess the distribution of usual total vegetable and fruit intake and how it relates to recommendations in the 2007 Canada's Food Guide.
Overall, Canadians reported consuming fewer total servings of vegetables and fruits in 2015 (4.5 average daily servings) than in 2004 (5.3 average daily servings). Lower total fruit intakes were explained by significantly lower intakes of fruit juice across nearly all age and sex groups, resulting in a decline of 0.3 average total daily fruit servings in the overall population. Lower vegetable consumption was largely driven by lower intakes of potatoes and, to a lesser extent, lettuce. Intakes of whole fruits and other vegetables remained largely unchanged. In both years, the majority of Canadians did not usually consume the number of total vegetable and fruit servings recommended for their age and sex group in the 2007 Canada's Food Guide.
Canadians reported consuming fewer vegetables and fruits in 2015 compared with 2004. This was largely driven by substantially lower consumption of fruit juice and, to a lesser extent, potatoes. These findings can serve as valuable baseline data to assess any changes in patterns of vegetable and fruit consumption in Canada.
每天食用大量蔬菜和水果是健康饮食的基础。本研究调查了2015年加拿大人蔬菜和水果的消费模式,并将其与2004年的数据进行比较。
2015年加拿大社区健康调查(CCHS)-营养部分以及2004年CCHS-营养部分(第2.2周期)提供了关于加拿大人蔬菜和水果摄入量的具有全国代表性的24小时饮食回忆数据。计算了每次调查年份总体以及按年龄和性别分组的蔬菜、水果及亚组的消费频率和每日平均摄入量。采用美国国家癌症研究所的方法来评估通常的蔬菜和水果总摄入量的分布情况以及它与《2007年加拿大食物指南》中的建议之间的关系。
总体而言,加拿大人报告2015年蔬菜和水果的总食用份数(平均每日4.5份)少于2004年(平均每日5.3份)。几乎所有年龄和性别组的果汁摄入量显著降低,导致总体人群每日水果总食用份数平均下降0.3份,从而解释了水果总摄入量较低的原因。蔬菜消费量较低主要是由于土豆摄入量减少,生菜摄入量减少的程度较小。完整水果和其他蔬菜的摄入量基本保持不变。在这两年中,大多数加拿大人通常并未达到《2007年加拿大食物指南》中针对其年龄和性别组建议摄入的蔬菜和水果总份数。
加拿大人报告2015年与2004年相比蔬菜和水果的消费量减少。这主要是由于果汁消费量大幅下降,土豆消费量下降的程度较小。这些发现可作为评估加拿大蔬菜和水果消费模式变化的宝贵基线数据。
