The Study
Nut consumption and risk of cardiovascular disease events and all-cause mortality: A systematic review and dose-response meta-analysis of prospective cohort studies.
This study combines results from many big health studies that followed people over time. It shows that people who eat more nuts tend to have fewer heart problems and live longer, but it can't prove that nuts are the reason why.
