Vic there is no cure for diabetes. There are ways of improving control and making diabetes better but there is no cure. If I eat grapes or drink grape juice it raise my blood sugar and I have to take insulin to compensate. Grapes are not one of the best choices of fruit for diabetics. I eat them sparingly. You can find so called "cures" frequently. Peolpe make lots of money off these fake cures and then magically disappear, never to be heard of again. They take their money and run. There is someone posting on this site now that he has a couple of cures for diabetes. Don't believe him.
