See the scientific wording

Consuming nuts at least twice per week is associated with a 56% lower risk of all-cause mortality.

Why this might work

Eating nuts regularly lowers inflammation in the body and makes blood vessels work better, which prevents damage to organs and reduces the chance of dying from any cause.
