豆类(干豆、豌豆、扁豆)是营养密集的食物，在加拿大的《食物指南》中被推荐为蔬菜或肉类和替代食物类别中的好选择。为了研究加拿大成年人(19岁)食用豆类食品的患病率及其对营养摄入量的影响，我们分析了2004年加拿大社区健康调查第2.2周期的横断面数据(N 20156)。参与者被分为非消费者和脉搏摄入量的四分位数。以文化背景、性别、年龄和经济状况为协变量，采用样本权重法和Logistic回归分析探讨营养素摄入量与脉搏摄入量之间的关系。在任何一天，13%的加拿大人都会消费豆类，这是亚洲人口中消费量最高的。最高四分位数的消费者的脉搏摄入量为294(SE 40)g/d，与非消费者相比，这些人的碳水化合物、纤维和蛋白质的摄入量更高。此外，与非消费者相比，豆类消费者的微量营养素摄入量增加，导致低于硫胺素、维生素B-6、叶酸、铁、镁、磷和锌的估计平均需要量的人数较少。尽管豆类中钠的含量普遍较低，但豆类消费者对钠的摄入量也较高。在豆类消费者的高四分位数中，水果和蔬菜的摄入量是一分位数较高的。这些数据表明，豆类消费支持饮食建议，即豆类应包括在健康饮食中。进一步的研究将有必要阐明豆类消费者钠含量增加的来源，这样增加豆类摄入量的饮食建议将使他们的营养益处最大化。
Pulses (dry beans, peas, lentils) are nutrient-dense foods that are recommended as good choices in either the vegetable or meat and alternative food groups in Canada's Food Guide. To examine the prevalence and the effect of pulse consumption on nutrient intake in Canadian adults (>= 19 years), we analysed cross-sectional data (n 20 156) from the 2004 Canadian Community Health Survey, Cycle 2.2. Participants were divided into non-consumers and quartiles of pulse intake. Sample weights were applied and logistic regression analysis was used to explore the association of nutrient intakes and pulse consumption, with cultural background, sex, age and economic status included as covariates. On any given day, 13% of Canadians consume pulses, with the highest consumption in the Asian population. The pulse intake of consumers in the highest quartile was 294 (SE 40) g/d and, compared with non-consumers, these individuals had higher intakes of carbohydrate, fibre and protein. As well, the micronutrient intake of pulse consumers was enhanced, resulting in fewer individuals who were below the estimated average requirement for thiamin, vitamin B-6, folate, Fe, Mg, P and Zn, compared with non-consumers. Although pulses are generally low in Na, its intake also was higher in pulse consumers. Among the higher quartiles of pulse consumers, fruit and vegetable intake was one serving higher. These data indicate that pulse consumption supports dietary advice that pulses be included in healthful diets. Further studies elucidating the sources of increased Na in pulse consumers will be necessary so that dietary advice to increase consumption of pulses will maximise their nutritional benefits.
