It is essential to check the nutritional value of crackers to ensure that they are suitable for diabetes prevention and management. Every serving of crackers should be less than 200 calories, contain less sodium, carbohydrates less than 25g, and at least 1g fibre per 15g carb. Since whole grain crackers fit into these nutritional values, they are the best crackers for diabetes. In addition, you can look for gluten-free, less salty, oatmeal or other whole-grain crackers to munch on.
