The present review provides an investigation into the food choice decisions made by individuals in relation to fruit and vegetable consumption. A comprehensive body of evidence now exists concerning the protective effect of fruit and vegetables against a number of diseases, particularly cardiovascular disease and certain forms of cancer. Current UK recommendations are to increase intakes of fruit and vegetables to 400 g/person per d. In the main body of the review the factors that affect food choice decisions of adults in relation to fruit and vegetable consumption are studied, following a suggested framework of food choice. Factors covered include sensory appeal, familiarity and habit, social interactions, cost, availability, time constraints, personal ideology, media and advertising and health. The content of the review shows just how complex the food choice process can be. Health promotion techniques can be better targeted towards certain groups of individuals, all holding similar sets of values, when making food choice decisions. Food choice, in relation to fruit and vegetable intake, needs to be studied in more depth, in order to provide effective nutrition education programmes, in particular the sets of priorities that different sub-groups of the population consider when making food choice decisions.
本综述对个人在水果和蔬菜消费方面的食物选择决策进行了调查。目前已有大量证据表明水果和蔬菜对多种疾病具有预防作用，尤其是心血管疾病和某些类型的癌症。英国目前的建议是将水果和蔬菜的摄入量增加到每人每天400克。在综述的主体部分，我们按照建议的食物选择框架，研究了影响成年人水果和蔬菜消费食物选择决策的因素。涵盖的因素包括感官吸引力、熟悉度和习惯、社交互动、成本、可获得性、时间限制、个人观念、媒体与广告以及健康因素。综述内容表明食物选择过程可能非常复杂。在制定食物选择决策时，健康促进技术可以更有针对性地针对某些持有相似价值观的特定人群。关于水果和蔬菜摄入量的食物选择需要更深入地研究，以便提供有效的营养教育计划，特别是不同人群亚组在做出食物选择决策时所考虑的优先事项。
