In plain English

Women aged middle-aged and older who eat nuts or peanut butter once to four times per week have a lower risk of dying from any cause compared to those who eat them less often.

See the scientific wording

Higher consumption of nuts and peanut butter, specifically once per week or 1–4 times per week, is associated with a 11–19% lower risk of death from all causes in middle-aged and older women, suggesting a potential protective effect of nut intake on overall mortality.

Why this might work

Eating nuts and peanut butter introduces antioxidants into the body, which neutralize harmful molecules that damage cells and blood vessels. This reduces inflammation in artery walls, prevents plaque buildup, and keeps blood vessels functioning properly, leading to fewer heart-related deaths and longer life.
