Diabetes is caused due to the deficiency of insulin in the blood, not by eating sugar.
Diabetes is a disease in which blood glucose or blood sugar levels are too high. Glucose comes from the foods we eat. Insulin is a hormone secreted by the pancreas that helps the glucose get into cells to give them energy. There are two types of diabetes - In Type 1 diabetes, the body does not produce insulin. The immune system destroys the insulin-producing cells in the pancreas. Sugar does not cause Type 1 diabetes. This condition can be managed with the help of insulin therapy and other treatments and by living a healthy lifestyle.
In Type 2 diabetes, the body’s cells aren’t able to respond to the insulin produced by the pancreas. In later stages of the disease, the body may also not produce enough insulin. Though sugar does not directly cause Type 2 diabetes, Type 2 diabetes can be managed with a healthy diet. However, eating large amounts of added sugar may increase the risk of getting type 2 diabetes if overweight.
University of Rochester Medical Center clarifies that sugar being a cause of diabetes is a myth, and eating sugar does not cause diabetes.
A study published in the American Diabetes Association's diabetic Care journal shows that intake of total or type of sugar is not associated with the risk of developing type 2 diabetes.
Therefore sugar consumption will not directly cause either type of diabetes. However, eating too much can cause weight gain. Obesity is a risk factor for type 2 diabetes.
