Short answer: Yes. Given how much of the population’s calories come from ultra‑processed foods (UPFs) and the consistency of links to major diseases, high UPF intake is best treated as a public‑health hazard, even as scientists continue to refine definitions and causal mechanisms. In the U.S., UPFs supply roughly 55–60% of daily calories and have increased over time, so even modest per‑person risk
