Scope The aim of current meta‐analysis was to investigate the relation between lycopene and risk of cardiovascular diseases (CVD). Methods and results Studies concerning about the association between lycopene and risk of CVD were searched on Pubmed, Embase, and Web of Science from inception to October 2016. A total of 14 eligible studies were identified. A significantly inverse association with a pooled risk ratio (RR) of 0.83 (95% CI: 0.76–0.90) was shown between lycopene exposure and risk of CVD. Findings were similar restricting to dietary studies (RR = 0.87, 95% CI = 0.79–0.96) and biomarker studies (RR = 0.74, 95% CI = 0. 62–0.87).Dietary lycopene intake was statistically significant for coronary heart disease (CHD) (RR: 0.87; 95% CI: 0.76–0.98) and stroke (RR: 0.83; 95% CI: 0.69–0.96).The pooled risk estimate was generally similar for lycopene biomarker concentrations, but the association was only statistically significant for stroke (RR: 0.65; 95% CI: 0.42–0.87). Subgroup analyses showed that retrospective and low quality studies were statistically significant sources of heterogeneity. Conclusion Higher lycopene exposure is inversely associated with a lower risk of CVD. Further well‐designed randomized clinical trials are required to assess the role of lycopene on CVD.
