The Claim
Higher walnut consumption is associated with a 14% reduction in total mortality per 0.5 serving (28 g) increase per day in U.S. adults aged 60 and older, and those consuming five or more servings per week have a 14% lower risk of total mortality compared to non-consumers.
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.
In U.S. adults aged 60 and older, eating more walnuts is linked to a lower risk of death from any cause. Each additional half-serving per day is associated with a 14% lower risk, and those eating five or more servings per week have a 14% lower risk than those who do not eat walnuts.

Eating walnuts delivers a type of fat called alpha-linolenic acid into the body, which changes the balance of fats in the blood and helps blood vessels relax and function better. This reduces the buildup of plaque in arteries and lowers the chance of heart attacks and strokes, which leads to people living longer.
What the research says
1 studyPeople who ate walnuts at least five times a week lived longer and were less likely to die from any cause than those who didn’t eat walnuts—even when accounting for other healthy habits.
