The Claim
Consuming walnuts at least five times per week is associated with an increase in life expectancy at age 60 of approximately 1.3 years in women and 1.26 years in men compared to non-consumers among older U.S. adults.
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 U.S. adults who eat walnuts at least five times a week live about 1.3 years longer past age 60 if they are women, and 1.26 years longer if they are men, compared to those who do not eat walnuts.
See the scientific wording
Consuming walnuts at least five times per week is associated with a gain of approximately 1.3 years in life expectancy at age 60 in women and 1.26 years in men, compared to non-consumers, suggesting a meaningful impact on longevity in older U.S. adults.
Eating walnuts regularly delivers a plant-based omega-3 fat called ALA into the body. This fat gets used to make signaling molecules that lower bad cholesterol, raise good cholesterol, and help blood vessels relax and function better. These changes reduce the buildup of plaque in arteries and prevent heart attacks and strokes, which allows people to live longer after age 60.
What the research says
1 studyPeople who ate walnuts five or more times a week lived about 1.3 years longer after age 60 than those who never ate walnuts, based on a long study of tens of thousands of older adults.
