Blood glucose is not created just by sweets—all foods create it. Proteins create glucose, fats create glucose, vegetables create glucose, fruits create glucose, fruit juices create glucose, starchy foods create glucose, and of course, sweets create glucose. The key to losing weight is to consume less of the foods (including drinks) that produce large amounts of glucose and replace them with foods and beverages that create smaller amounts of glucose and go into the bloodstream more slowly.
