The Claim
Higher consumption of nuts, defined as three or more servings per week (each serving 28 grams), is associated with a 29% lower risk of all-cause mortality in adults aged 40 and older.
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.
Adults aged 40 and older who eat at least three servings of nuts per week have a 29% lower risk of dying from any cause compared to those who eat fewer servings.
See the scientific wording
Higher consumption of nuts, particularly three or more servings per week (each serving 28 grams), is associated with a 29% lower risk of all-cause mortality in adults aged 40 and older, as observed in a large prospective cohort study of 50,045 individuals in northeastern Iran, even after adjusting for age, sex, smoking, alcohol, opium use, wealth, BMI, and dietary factors, suggesting a consistent link between nut intake and longevity in diverse populations.
Eating nuts regularly lowers harmful inflammation and damage from free radicals in the body, which keeps blood vessels healthy and improves how the body uses sugar and fats, reducing the chance of fatal diseases like heart attacks and strokes.
What the research says
1 studyStudy: Nut consumption and total and cause-specific mortality: results from the Golestan Cohort Study.
People who ate at least three handfuls of nuts every week were 29% less likely to die during the study, even when scientists accounted for other health habits like smoking or weight. This suggests eating nuts regularly may help people live longer.
