Explainer Ultra-processed food was tied to a 19 percent higher risk of heart death in a 25-year study

Those who ate the most ultra-processed food were more likely to die of cardiovascular disease, and the extra risk held even after accounting for sugar, salt and overall diet quality. Because it observed eating habits rather than assigning them, it shows a link, not proof.
