The Claim

Among Korean adults aged 40–79, consuming two or more servings of nuts per week (30 grams) is associated with a 12% lower risk of all-cause mortality over a median follow-up of 12.3 years, after adjustment for age, sex, BMI, income, education, smoking, alcohol, physical activity, and chronic disease history.

In plain English

Korean adults aged 40–79 who eat at least two servings of nuts per week have a 12% lower risk of dying from any cause over 12.3 years compared to those who eat fewer servings, after accounting for lifestyle and health factors.

See the scientific wording

Among Korean adults aged 40–79, consuming two or more servings of nuts per week (30 grams) is associated with a 12% lower risk of all-cause mortality over a median follow-up of 12.3 years, after adjusting for age, sex, BMI, income, education, smoking, alcohol, physical activity, and chronic disease history, suggesting that regular nut intake may contribute to longer life expectancy in this population.

Why this might work

Eating nuts lowers bad cholesterol and blood pressure by changing how the liver handles fats and by feeding good gut bacteria that produce beneficial compounds. Nuts also make you feel full longer, so you eat fewer calories and gain less weight. This reduces fat buildup, high blood pressure, and diabetes, which lowers the chance of dying from heart disease, stroke, or other illnesses.
