Repeated exposure to fruit results in increased fruit intakes in older low consumers of fruit

Abstract

Recent reports suggest low fruit and vegetable intakes in older people. This study investigated the impact of two community-based repeated exposure interventions on fruit intakes in older people. Ninety-five participants (aged 65 years and over) were randomized to receive either one (E1), five (E5) or five plus (E5+) exposures to fruit over a 5 week period. Fruit exposures occurred during fruit tasting sessions (E1, E5, E5+), and through fruit provision (E5+), in community-based social group meetings. Intakes of fruit and vegetables were assessed before and after interventions. In low consumers of fruit (1 portion/day or less), fruit intakes increased significantly in the repeated exposure groups (E5, E5+), but no differences were found between E5 and E5+ groups and no change was found in the single exposure group. Similar effects were also found in fruit and vegetable intakes. Compared to single exposure, repeated exposure to fruit via fruit tasting sessions once per week for five weeks in a community setting significantly improved fruit intakes, and fruit and vegetable intakes in older low consumers of fruit, although no benefits of additional fruit provision were found. Repeated exposure was also easy to implement, low cost and enjoyable.
