Global Burden of Disease Study 2019 — Diet as the leading risk factor
In plain English
The IHME Global Burden of Disease project quantifies how much of global mortality is attributable to each modifiable risk. In the 2019 cycle, dietary risks — low whole grains, low fruit, low vegetables, low nuts/seeds, high sodium, high processed meat — rank as the single largest cause of premature death worldwide, ahead of tobacco.
Why it matters
Diet is the leading risk factor for premature death worldwide.

Caveats
GBD is a modelled synthesis, not a primary study. Diet-attributable estimates rely on counterfactual exposure assumptions that have been debated.
