Diabetes is a chronic metabolic disease, and the occurrence of diabetes is closely related to genetics, environment, infection, and lifestyle. Drinking too much brown sugar does not necessarily lead to diabetes, but it is still not recommended to drink too much brown sugar for the following reasons: First, brown sugar is sucrose, and eating too much brown sugar can easily cause an excess of total calories. The human body’s long-term intake of total caloric excess will cause weight gain, and even obesity. Obesity is an important cause of insulin resistance, and insulin resistance is an important cause of diabetes. Second, too much brown sugar drinking is likely to increase the functional burden of the pancreatic beta cells, and even cause pancreatic beta cell hypofunction, pancreatic beta cell hypofunction is also an important cause of diabetes. Therefore, drinking too much brown sugar will not necessarily lead to diabetes, but it is easy to cause obesity, and also easy to increase the functional burden of pancreatic beta cells, so it is not recommended to drink too much brown sugar.
