Ultra-Processed Foods Linked to Higher Risk of Heart Disease and Early Death
A new European Heart Journal consensus statement links high consumption of ultra‑processed foods (UPFs) to significantly higher risks of heart disease and cardiovascular death. The analysis of existing studies finds up to a 19% increase in heart disease, 13% higher atrial fibrillation risk, and a 65% rise in cardiovascular mortality for the heaviest UPF eaters. UPFs now supply over half of daily calories in the UK and the Netherlands, yet most dietary guidelines still ignore processing levels. The authors urge doctors to discuss UPF intake with patients and call for clearer labeling and policy action.
