2026 Study: Poor Diet Linked to 4 Million Heart Disease Deaths Annually
Global, regional and national burden of ischemic heart disease attributable to suboptimal diet, 1990–2023: a Global Burden of Disease study GBD 2023 IHD & Dietary Risk Factors Collaborators Nature Medicine ( 2026 ) Cite this article 1654 Accesses 130 Altmetric Metrics details Abstract Ischemic heart disease (IHD) remains a leading cause of death worldwide, with dietary risks being its most significant modifiable factor. Here, using the Global Burden of Diseases, Injuries and Risk Factors Study 2023, we estimated the mortality and disability-adjusted life years from diet-related IHD across 204 countries. In 2023, a suboptimal diet was responsible for 4.06 million (95% uncertainty interval (UI) 0.74–6.22) IHD deaths and 96.84 million (18.82–142.52) IHD disability-adjusted life years. The global age-standardized death rate of IHD attributable to suboptimal diet decreased by 43.92% (95% UI 34.44–53.23) per 100,000 population from 1990 to 2023. Among dietary fact...
