Experts say that while eating too much sugar can hinder your health, especially when you do have diabetes, sugar is not a cause of diabetes.
In the article, Sugar and Diabetes, by Diabetes UK (https://www.diabetes.org.uk/guide-to-diabetes/enjoy-food/eating-with-diabetes/food-groups/sugar-and-diabetes) they state that sugar does not cause diabetes, but the answer is more complicated when we talk about type one and two of diabetes.
"We know that sugar does not cause type 1 diabetes, nor is it caused by anything else in your lifestyle. In type 1 diabetes, the insulin producing cells in your pancreas are destroyed by your immune system.
With type 2 diabetes, the answer is a little more complex. Though we know sugar doesn’t directly cause type 2 diabetes, you are more likely to get it if you are overweight. You gain weight when you take in more calories than your body needs, and sugary foods and drinks contain a lot of calories.
So you can see if too much sugar is making you put on weight, then you are increasing your risk of getting type 2 diabetes. But type 2 diabetes is complex, and sugar is unlikely to be the only reason the condition develops."
So yes, you do not directly get diabetes from sugar intake, and a great reminder to know is that we all have sugar in our bodies that are helpful and needed. We need to watch our sugar intake but know it is not a direct causation of diabetes.
