The Study
Consumption of nuts and risk of total and cause-specific mortality over 15 years.
This study watched a group of older adults for 15 years to see who lived longer and whether eating more nuts was linked to living longer. It found people who ate more nuts tended to live longer, especially from heart problems, but it can't prove the nuts were the reason.

Quality score
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.

People who eat nuts have a lower rate of death from any cause compared to those who do not eat nuts.
If you're an adult and eat nuts at least seven times a week, you might be less likely to die from any cause over time — about 20% less likely, according to this claim.
If you're 49 or older and eat more nuts—especially compared to people who eat very few—you might live longer. One study found that people who ate a moderate amount had about a 24% lower chance of dying over 15 years.
If you're 49 or older, eating a moderate amount of nuts—more than very little but not the most—might help you live longer by lowering your chances of dying from heart disease.
Eating more nuts may help older women live longer — especially by lowering their chances of dying from heart disease or stroke over the next 15 years.
