A research model of dietary intake in 184 countries, developed by researchers at the Friedman School of Nutrition Science and Policy at Tufts University, estimates that poor diet contributed to over 14.1 million cases of type 2 diabetes（糖尿病） in 2018, representing over 70% of new diagnoses globally. The analysis, which looked at data from 1990 and 2018, provides valuable insight into which dietary factors are driving the burden of type 2 diabetes in the world region.
Of the 11 dietary factors considered, 3 had an outsized contribution to the rising global incidence of type 2 diabetes: insufficient intake of whole grains, excesses of refined（精制的）rice and wheat, and the overconsumption of processed meat. Factors such as drinking too much fruit juice and not eating enough non-starchy vegetables, nuts, or seeds, had less of an impact on new cases of the disease.
"Our study suggests poor carbohydrate quality is a leading driver of diet-attributable type2 diabetes globally, and with important variation by nation and over time," said senior author Dariush Mozaffarian, Jean Mayer Professor of Nutrition. "These new findings reveal critical areas for national and global focus to improve nutrition and reduce devastating burdens of diabetes."
Type 2 diabetes is characterized by the resistance of the body's cells to insulin（胰岛素）. Of the 184 countries included in the Nature Medicine study, all saw an increase in type 2 diabetes cases between 1990 and 2018, representing a growing burden on individuals, families, and healthcare systems.
The analysis revealed that poor diet is causing a larger proportion of total type 2 diabetes incidence in men versus women, in younger versus older adults, and in urban versus rural residents at the global level. Regionally, Central and Eastern Europe and Central Asia, particularly in Poland and Russia, where diets tend to be rich in red meat, processed meat, and potatoes, had the greatest number of type 2 diabetes cases linked to diet.
