The Study
Nut consumption and 5-y all-cause mortality in a Mediterranean cohort: The SUN project
This study watched a group of people for five years and noticed that those who ate more nuts tended to live longer. But it didn't make them eat nuts — they chose it themselves. So we can't say nuts made them live longer, just that the two things happened together.
Analysis score
Maximum 72 for a cohort study.
Where the score came from
Scientists followed thousands of Spanish university graduates for five years to see if eating nuts every week made them less likely to die from any cause.

Groups of people are followed over time to see who develops an outcome. Strong for identifying risk factors and associations, but cannot prove causation as firmly as RCTs.
Key takeaways
Summary
Based on the study abstract and findings.
- 1That’s like cutting your risk of dying in half just by snacking on nuts a couple times a week — even after accounting for how healthy their overall diet and lifestyle were.
- 2People who ate nuts at least twice a week were 56% less likely to die during the study than those who rarely ate nuts.
