Abstract

Context Controversy exists regarding the association between fruit and vegetable consumption and all-cause and cause-specific mortality among individuals with type 2 diabetes (T2D). Objective This study aims to inform dietary recommendations and add to the body of evidence by providing a thorough investigation of the association between the consumption of fruits and vegetables and the mortality risk in patients with T2D. The literature on this association was evaluated by a comprehensive systematic review and meta-analysis. Data Sources PubMed, Scopus, and Web of Science were searched up to 29 June 2024. Data Extraction Prospective cohort studies involving participants with diabetes aged over 18 years reporting risk estimates for the association between total fruit and vegetable intake and all-cause or cause-specific mortality (including cardiovascular disease [CVD], coronary heart disease, and stroke) were included. Data Analysis A random-effects approach was applied for combining risk estimates, and dose-response relationships were assessed using restricted cubic splines. Overall, 9 studies with 75082 participants and 7590 deaths were included. Compared with the lowest intake, the highest fruit intake was associated with a decreased risk of all-cause (hazard ratio [HR]: 0.82; 95% CI: 0.75, 0.90; n = 6) and CVD (HR: 0.90; 95% CI: 0.84, 0.97; n = 4) mortality. The highest vegetable intake was also related to reduced all-cause (HR: 0.85; 95% CI: 0.73, 0.98; n = 6) and CVD (HR: 0.97; 95% CI: 0.94, 0.99; n = 2) mortality risk. An additional 200 g/day of fruit and vegetable consumption was associated with a 26% and 14% lower risk of all-cause mortality. Conclusion This meta-analysis indicates an inverse association between fruit and vegetable intake and mortality from all causes and CVD in T2D patients. © 2025 Elsevier B.V., All rights reserved.
