What are the main dietary factors contributing to the rise in global type 2 diabetes cases according to recent research?

### Key Dietary Factors in Rising Type 2 Diabetes Cases A recent study published in Nature Medicine has identified three major dietary factors contributing to the global increase in type 2 diabetes cases: 1. **Insufficient Intake of Whole Grains**: Whole grains are essential for maintaining stable blood sugar levels and providing essential nutrients. A lack of whole grains in the diet has been linked to an increased risk of type 2 diabetes. 2. **Excess Consumption of Refined Rice and Wheat**: Refined grains, such as white rice and white bread, have been stripped of their fiber and nutrients, leading to rapid spikes in blood sugar levels. Overconsumption of these refined grains is a significant factor in the rise of type 2 diabetes. 3. **Overconsumption of Processed Meat**: Processed meats, such as sausages, bacon, and deli meats, are high in unhealthy fats and preservatives. Regular consumption of processed meats has been associated with an increased risk of type 2 diabetes. The study found that poor diet contributed to over 14.1 million cases of type 2 diabetes in 2018, representing more than 70% of new diagnoses globally. The research highlighted that eating too many unhealthy foods was a more significant driver of type 2 diabetes than not eating enough wholesome foods. This trend was particularly noticeable among men, younger adults, and urban residents. Researchers used data from the Global Dietary Database and a computer model to analyze dietary intake in 184 nations from 1990 to 2018. They also examined demographics, estimates of type 2 diabetes incidence, and data on food choices and health from other studies. The findings suggest that poor carbohydrate quality is a leading driver of diet-attributable type 2 diabetes globally. The study emphasizes the need for national and global efforts to improve nutrition and reduce the burden of diabetes. Regions with the highest proportion of new cases included central and eastern Europe, central Asia, Latin America, and the Caribbean, while South Asia had the lowest proportion. More cases were found in men than women and in urban areas compared to rural areas.
