The influence of dietary vegetables and fruits on endometrial cancer risk: a meta-analysis of observational studies
A partir d'une revue systématique de la littérature publiée jusqu'en août 2021 (27 études), cette méta-analyse évalue l'association entre une consommation de fruits et de légumes et le risque de cancer de l'endomètre, en fonction de leurs composants bioactifs et de leurs micronutriments
Fruits and vegetables store many bioactive compounds and micronutrients, making their consumption ideal for maintaining good health. A previous meta-analysis in 2007 provided evidence that high vegetable and cruciferous vegetable intake might help prevent endometrial cancer (EC) development. The current study purposely explored the favorable effects of vegetables, fruits, and their other specific types using a review of the most recent papers. We conducted a systematic search through August 2021 in the PubMed and EMBASE databases on this topic, through which twenty-seven studies, consisting of 21 case-control and 6 cohort studies, were obtained. The results showed that vegetables (pooled odds ratio [OR], relative risk [RR], hazard ratio [HR] = 0.76, 95% confidence interval [CI] 0.63–0.91), cruciferous vegetables (pooled OR = 0.81, 95% CI 0.70–0.94), dark green and yellow/orange combined vegetables (pooled OR = 0.64, 95% CI 0.42–0.97), and fruits (pooled OR = 0.81, 95% CI 0.70–0.92) were strongly associated with a reduced risk of EC. These results were primarily based on studies of high quality and exhibited either by case-control only or a combination of case-control and cohort studies. Additionally, the results varied by geographic location, such as Western areas, the US, and Italy. This meta-analysis suggested that the consumption of fruits and vegetables has beneficial effects on EC risk and that specific kinds of fruits and vegetables should be recommended differently due to their outstanding bioactive components.
