Background: Chilli-pepper (CP) is well known for its anti-inflammatory, antioxidant, anticancer, and blood glucose regulation effects. However, the impact of CP on all-cause and cardiovascular mortality is not clear. Methods: A comprehensive search was performed using Ovid, Cochrane, Medline, Embase, and Scopus. We screened the studies from inception till January 16, 2020, and reported the outcomes of our interest after consumption of CP (Figure1a). The inclusion criteria were: all observational and randomized controlled trials reporting the outcomes of interest, and pediatric, animal studies, letters/case reports, reviews, abstracts, and book chapters were excluded. All-cause mortality was studied as the primary endpoint. Cardiovascular, cerebrovascular, and cancer-related deaths were studied as secondary outcomes. Results: From 4729 studies screened, four studies including 570,762 subjects met the inclusion criteria. Random-effects pooled analysis showed that there was a 25% reduction in the relative risk of all-cause mortality for regular CP consumers, compared to non-consumers (relative risk (RR): 0.75; 95% confidence intervals (CI): 0.64-0.88, p = 0.0004, Figure1b). Furthermore, there were a 26% and 23% reduction in the RR of death due to cardiovascular causes (RR: 0.74; 95% CI: 0.62-0.88, p=0.0006, Figure1c) and cancer (RR: 0.77; 95% CI: 0.71-0.84, p=0.0001, Figure 1d), respectively. However, there were no statistically significant differences in cerebrovascular accidents (RR: 0.76; 95% CI: 0.36-1.60, p=0.47).Conclusion: In a contemporary meta-analysis of 570,762 subjects, regular CP consumption was associated with a significant reduction in all-cause, cardiovascular, and cancer-related mortalities. Future studies are needed to better understand the potential mechanisms of the mortality benefits of CP consumption.
