The reason why blood sugar levels in normal individuals remain within a normal range is due to the regulation by sufficient insulin. In individuals with diabetes, there is a relative or absolute deficiency of insulin, which impairs the regulation of sugar, leading to elevated blood sugar. Therefore, the statement that developing diabetes is caused by consuming too much sugar is not accurate. However, it is advisable for individuals with diabetes to avoid sugar. Currently, the onset of diabetes is believed to be associated with multiple factors, including genetics, environment, and immunity. According to literature reports, a high-carbohydrate diet is not significantly linked to the development of diabetes, and the incidence of diabetes in individuals on a high-carbohydrate diet is not higher than in those on a high-protein diet. However, excessive consumption of simple sugars, such as white sugar, can lead to obesity, which may trigger diabetes.
