People with diabetes may need to count carbs when they are planning their meals. The American Diabetes Association suggests that diabetics choose fresh fruits, 100 percent fruit juice or dried fruits to incorporate into their meal plans. Approximately 2 tablespoons of dried fruits like raisins can contain 15 grams of carbs. People with diabetes can eat many fruits, but they should also be aware of the glycemic index, or GI, associated with them. For example, melons, pineapples and certain dried fruits have a medium value for the GI.
