DOI: https://doi.org/10.1093/ajcn/nqy339 Interpretive Summary: Technical Abstract: Fruit and vegetable (FV) consumption is vital for chronic disease prevention and overall health. There have been several school-based interventions aimed at increasing FV consumption, which achieved short-term increases in FV intake. However, long-term sustained effects on FV consumption are unknown. The purpose of this article was to assess the acceptability of the methods used for a study published in the December 2018 issue of the American Journal of Clinical Nutrition. It was the first study attempting to assess possible sustained effects of an FV intervention at 14 years post intervention; no significant effects were found on FV or unhealthy snack consumption. This article outlines the study strengths and weaknesses, which are important qualifiers to the reported results, and need to be considered for a better conceptualization and implementation of a dietary intervention study. |
