DiscussionFollowing the delivery of a nutrition-focused intervention to older adults attending senior centers, those within the intervention group consumed significantly more of the fruits and vegetables offered in their congregate lunch meal from pre- to post-intervention. Additionally, the intervention group had a significant increase in phytochemical knowledge, and it was more likely to self-report participation in positive behaviors associated with fruit and vegetable consumption compared to the control group. Moreover, this was the first study to calculate an average meal PI score based on a particular AAA’s lunch menu. This study was also first to determine an average meal PI score based on participants’ intake of their congregate lunch meal as assessed by plate-waste measurements.Increasing the consumption of a variety of fruits and vegetables has been shown to provide many favorable health benefits among older adults including the potential of delaying or improving the management of chronic diseases (Murphy et al., 2012). The phytochemicals found in fruits and vegetables are believed to have a role in providing these positive health effects. In the current pilot study, the health benefits of various phytochemicals were emphasized in nutrition lessons and the educational tools by associating the primary phytochemicals found within each color category with their related health benefits.
