需要采取有效的策略来根据健康建议增加蔬菜摄入量。先前的研究表明，增加食物种类会导致消费量增加，但尚未对这种促进蔬菜摄入量的策略进行研究。这项交叉研究于 2008 年和 2009 年进行，测试了半个盘子里装满各种蔬菜是否会影响蔬菜消耗和膳食能量摄入。 66 名成年人（34 名女性，32 名男性）每周一次，连续 4 周，随意食用一顿意大利面和煮熟的蔬菜。膳食中提供的蔬菜类型各不相同：三餐中提供 600 克的单一蔬菜（西兰花、胡萝卜或豌豆），而一顿饭中三种蔬菜中的每一种并排提供 200 克。使用具有重复测量的混合线性模型来分析数据。在这项研究中，提供多种蔬菜可以增加膳食中的蔬菜摄入量（P
Effective strategies are needed to increase vegetable intake in accordance with health recommendations. Previous research has shown that increasing the variety of foods leads to increased consumption, yet this strategy has not been investigated for promoting vegetable intake. This crossover study, conducted in 2008 and 2009, tested whether filling half the plate with a variety of vegetables influences vegetable consumption and meal energy intake. Once a week for 4 weeks, a meal of pasta and cooked vegetables was consumed ad libitum by 66 adults (34 women, 32 men). The meals were varied in the type of vegetables offered: at three meals 600 g of a single vegetable was served (broccoli, carrots, or snap peas) and at one meal 200 g of each of the three vegetables was served side by side. Data were analyzed using a mixed linear model with repeated measures. In this study, serving a variety of vegetables increased vegetable intake at the meal (P
