Eating a lot of sugar definitely does not cause diabetes, if you don't eat so much sugar that you gain weight.C. Ronald Kahn, M.D. (cont.)
And in fact, sugar to a certain extent, is okay because it stimulates the pancreas to make more insulin which actually helps control the blood sugar. And so, actually you need a certain amount of carbohydrate in your diet to have your pancreas working normally.C. Ronald Kahn, M.D. (cont.)

And I say that that's not the right focus. The focus for you should be to make sure you keep your weight down, because people who have a family history of diabetes, if they stay thin, have no more risk of diabetes than the general population.C. Ronald Kahn, M.D. (cont.)
But if they become overweight, then their risk is 10 times higher than in the general population. So you can make a difference ten fold in your risk of diabetes if you've got a family history. If you stay thin, it's good, if you gain weight it's bad.","publisher":"WebMD Video"} ]]>
