A study estimates that 14.1 million people suffered from type 2 diabetes due to poor diet in 2018.
The analysis, conducted between 1990 and 2018, looked globally at what were the nutritional factors that caused type 2 diabetes on such a large scale.
The findings are based on a research model of dietary intake in 184 countries by researchers from the Friedman School of Nutrition Science and Policies at Tufts University in the US.
Scientists said that out of 11 nutritional factors in the study, three factors were found to have contributed to the increase in the rate of type 2 diabetes globally. These factors included inadequate use of fortified grains such as barley and proven wheat, excessive use of shredded rice and wheat, and excessive use of processed meat.
According to the results of the study, drinking fruit juice and insufficient consumption of low-starch vegetables, nuts or seeds had very little effect on new cases of the disease.
"The results suggest that poor quality carbohydrates are the main cause of dietary diabetes globally," said study senior author Daryush Muzaffareen.
He said that the results have identified areas where domestic and foreign attention will have to be paid to improving the diet and reducing the burden of diabetes.
