PURPOSE
A national survey of adult Canadians (n = 1,544) was recently undertaken (1997-1998) to monitor whether changes in dietary intake have occurred since the last Canadian dietary survey, conducted a generation ago (1970).
METHODS
Individuals from randomly selected households from a stratified sample of 80 enumeration areas from five regions of Canada were interviewed by a dietitian at home for a 24-hour dietary recall and food frequency questionnaire.
RESULTS
The mean dietary % energy from protein (16-18%), carbohydrate (50-56%) and fat (29-31%) was close to recommended levels in the different age-sex groups. Fat intake was reduced from previous surveys. Intakes of dairy products and fruits and vegetables are lower than recommended. Nutrient values at the 25th percentile of the nutrient distribution, were below recommended levels for calcium, folate, iron and zinc among women.
CONCLUSION
Despite the growing problem of obesity, Canadians are eating less fat than a generation ago but intake of certain nutrients are still suboptimal.
目的
最近（1997 - 1998年）对1544名成年加拿大人进行了一项全国性调查，以监测自上一次加拿大饮食调查（在一代人之前，即1970年进行）以来饮食摄入量是否发生了变化。
方法
从加拿大五个地区80个普查区的分层样本中随机抽取家庭的个体，由营养师在家中进行访谈，采用24小时饮食回顾法和食物频率问卷。
结果
不同年龄 - 性别组中，蛋白质（16 - 18%）、碳水化合物（50 - 56%）和脂肪（29 - 31%）提供的膳食能量百分比均值接近推荐水平。脂肪摄入量较之前的调查有所减少。乳制品以及水果和蔬菜的摄入量低于推荐水平。在营养素分布的第25百分位数处，女性的钙、叶酸、铁和锌的营养素值低于推荐水平。
结论
尽管肥胖问题日益严重，但加拿大人摄入的脂肪比一代人之前减少了，但某些营养素的摄入量仍不理想。
