目的：探讨特定健康知识和口味对甘蓝类蔬菜（西兰花、红甘蓝和绿甘蓝、西兰花、花椰菜、抱子甘蓝）接受度的相对重要性。设计:在一份成年人样本中，所有报告中高体力活动（作为健康行为的标志/控制）和报告低蔬菜摄入量（= 3份/天）的成年人中，一半蔬菜摄入量低的人（Li组）和一半蔬菜摄入量高的人（Hi组）获得了癌症保护信息，而另一半没有（Ln和Hn组），在快乐（9分）之前。对6种芸苔菜样品进行了味觉感知和风味影响反应（100毫米尺度）。此外，还测量了对健康、快乐和奖励食品的态度、社会人口统计学、在不久的将来消费蔬菜的意图以及对健康信息的回忆。研究对象：年龄在18-55岁的成年男女共200人。地点：澳大利亚阿德莱德中心位置测试。结果：Li、Hi信息组报告了特异性的防癌信息知识，与Ln、Hn组相比，差异有统计学意义（P < 0.000）。信息独立地影响了对球芽甘蓝（最不受欢迎的）的反应。多变量回归分析发现，感官知觉倾向于预测食用芸苔类蔬菜的喜好和意向。例如，西兰花的苦味（β = -0.38）、风味（β = 0.31）、甜味（β = 0.17）和女性性别（β = 0.19）可以预测其享乐性（调整R-2 = 0.37），而苦味（β = -0.38）、风味（β = 0.24）、女性性别（β = 0.20）和蔬菜摄入量（β = 0.14）可以预测其消费意愿（调整R-2 = 0.20） （P < 0.05）。结论：为了提高芸苔类蔬菜的受欢迎程度，解决味道维度（同时保留健康化合物）可能比宣传健康信息更重要。
Objective: To investigate the relative importance of specific health knowledge and taste on acceptance of Brassica vegetables (broccoli, red and green cabbages, broccolini, cauliflower, Brussels sprouts).Design: In a sample of adults all reporting medium-high physical activity (as a marker/control of health behaviour) and reporting either low (= 3 portions/d) vegetable intake, half of those with low vegetable consumption (Li group) and half of those with high vegetable consumption (Hi group) received cancer protection information, while the other half did not (Ln and Hn groups), before hedonic (9-point), perceived taste and flavour impact responses (100 mm scales) to samples of six Brassica vegetables were elicited. Additionally, attitudes towards foods for health, pleasure and reward, sociodemographics, intentions to consume the vegetables in the near future and recall of health information were also measured.Subjects: Adult males and females (n 200) aged 18-55 years.Setting: Central location testing, Adelaide, Australia.Results: Information groups Li and Hi reported specific cancer protection information knowledge, in contrast to Ln and Hn groups (P < 0.000). Information independently influenced responses to (the least liked) Brussels sprouts only. Multivariate regression analysis found sensory perception tended to predict liking and intentions to consume Brassica vegetables. For example, broccoli hedonics (adjusted R-2 = 0.37) were predicted (P < 0.05) by bitterness (beta = -0.38), flavour (beta = 0.31), sweetness (beta = 0.17) and female gender (beta = 0.19) and intentions to consume (adjusted R-2 = 0.20) were predicted (P < 0.05) by bitterness (beta = -0.38), flavour (beta = 0.24), female gender (beta = 0.20) and vegetable intake (beta = 0.14).Conclusions: Addressing taste dimensions (while retaining healthy compounds) may be more important than promoting health information in order to increase the popularity of Brassica vegetables.
