Poor Diet Linked to Heart Disease, but Australia Has Seen Improvements in the Last 30 Years
A new Nature Medicine analysis of 204 countries links suboptimal diet to over 4 million ischemic heart disease deaths and nearly 97 million disability‑adjusted life years in 2023. The study identifies low intake of whole grains, omega‑6 fatty acids, nuts and seeds, and high sodium as the leading dietary culprits. While Australasia, Western Europe and high‑income North America have cut diet‑related heart disease deaths dramatically since 1990, central sub‑Saharan Africa experienced a 21% rise. The findings underscore divergent nutritional challenges across income levels.
