Suboptimal dietary intake is responsible for 70.3% of global incident type 2 diabetes cases, with the largest burdens driven by insufficient whole-grain intake, excess refined rice and wheat, and excess processed meat.
Focus on increasing whole grains, reducing refined grains (rice/wheat), and limiting processed meats. These three factors alone account for the majority of diet-attributable diabetes risk globally.

In 2018, suboptimal intake of these dietary factors was estimated to be attributable to 14.1 million (95% uncertainty interval (UI), 13.8–14.4 million) incident T2D cases, representing 70.3% (68.8–71.8%) of new cases globally. Largest T2D burdens were attributable to insufficient whole-grain intake (26.1% (25.0–27.1%)), excess refined rice and wheat intake (24.6% (22.3–27.2%)) and excess processed meat intake (20.3% (18.3–23.5%)).
