Methods: In this descriptive and ecological study, data were obtained from the Global Burden of Disease Study, 2021. Age-standardized and sex-specific PAFs for mortality attributable to dietary risks and PAFs for mortality attributable to selected and specific dietary risks were calculated for six noncommunicable diseases worldwide for the 22-year period. The trend of PAFs over time was assessed by joinpoint regression analysis. Results: The two diseases with the highest mean PAF for mortality attributable to dietary risks were hypertensive heart disease followed by ischemic heart disease (0.63±0.01 and 0.45±0.01, respectively). The mean PAF for mortality attributable to dietary risks differed between sexes for four diseases. All six diseases had dietary risk-attributable mortality starting at a young age. Over a 22-year period, PAF for mortality attributable to dietary risks followed a significant decreasing trend for all six diseases. When the PAFs for mortality attributable to selected and specific dietary risks were examined, the majority showed a decreasing trend. Conclusion: It is essential to clarify the relationship between NCDs and dietary risks. This is because the human body is exposed to nutritional and dietary risks every day, both as individuals and as a community. https://ijph.tums.ac.ir/index.php/ijph/article/view/38935 https://ijph.tums.ac.ir/index.php/ijph/article/download/38935/8728
