The Claim
Among older adults at high cardiovascular risk, consuming more than three servings of walnuts per week is associated with a 45% lower risk of all-cause mortality compared to those consuming fewer servings, and this association is stronger than that observed for other nuts.
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.
Older adults with high cardiovascular risk who eat more than three servings of walnuts per week have a 45% lower risk of dying from any cause compared to those who eat fewer walnuts, and this effect is stronger than the effect seen with other nuts.
See the scientific wording
Among older adults at high cardiovascular risk, consuming more than three servings of walnuts per week is associated with a 45% lower risk of all-cause mortality, which is stronger than the association observed for other nuts.
Walnuts release compounds that calm down harmful inflammation and stop damage from free radicals in the blood, which lets blood vessels work better and keeps cells from dying too soon, lowering the chance of death from any cause.
What the research says
1 studyStudy: Frequency of nut consumption and mortality risk in the PREDIMED nutrition intervention trial
In older adults at high heart disease risk, eating walnuts more than three times a week was linked to a 45% lower chance of dying from any cause — better than other nuts. The study found this directly by tracking what people ate and who died over nearly five years.
