Is variety more important than quantity of fruits and vegetables in relation to cardiovascular disease incidence and mortality? Results from a prospective cohort study.

We aimed to prospectively assess the association between variety and quantity of fruits and vegetables (FV) and cardiovascular diseases (CVD) incidence and mortality due to the limited evidence. Our analysis included 2,918 adults with a follow-up period of 29,559 person-years. An inverse association was detected between fruit intake and the risk of incidence and mortality from CVD. We found no association between diversity scores of fruits, vegetables, and FV with CVD risk. Subjects with high quantity-high variety, high quantity-low variety, and low quantity-high variety of fruits, vegetables, or FV exhibited no difference in CVD risk compared to the subjects with low quantity-low variety intake. Increasing the variety of FV was associated with increases in the intake of β-carotene, lycopene, lutein, vitamin C, selenium, fibre, fat, and protein after adjustment for the quantity and covariates. We detected an inverse association between fruit intake and the incidence and mortality rates of CVD.
