An increase in the proportion of ultraprocessed foods in the diet is associated with a higher risk of all-cause mortality in middle-aged adults.
To lower your risk of early death, try to reduce the percentage of your diet that comes from ultraprocessed foods (like packaged snacks, sugary drinks, and ready meals). Even a small reduction in these items can have a measurable positive impact on your longevity.
After adjustment for a range of confounding factors, an increase in the proportion of ultraprocessed foods consumed was associated with a higher risk of all-cause mortality (HR per 10% increment, 1.14; 95% CI, 1.04-1.27; P = .008).
Why this rating
Large prospective cohort (n=44,551) with long follow-up and rigorous adjustment, but observational design prevents causal inference.
