The Claim
Higher consumption of nuts and peanut butter, at a frequency of once per week or 1–4 times per week, is associated with an 11–19% lower risk of death from all causes in middle-aged and older women.
What the research says
Supports is higher
Support is ahead, but a single strong opposing study can change this.
These are independent scores, not a percentage. Higher-grade studies count more, so a single strong opposing study can outweigh several weaker ones.
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.
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.
What the research says
1 studyStudy: Health benefits of nuts: potential role of antioxidants
Women who ate nuts or peanut butter at least once a week were less likely to die during the study, and those who ate them 1–4 times a week had the lowest risk — exactly what the claim says.
