Corn chips contain 10 grams of fat per serving, which may not fit with certain goals. A 1-ounce portion contains 15 grams of carbohydrate and very little protein. As a diabetic, you need a good helping of protein with every meal and snack. If you pay attention to portion sizes and add some protein to this snack, you can usually enjoy it in moderation. Most of time, aim to consume healthier snacks such as fruit, nuts and low-fat yogurt.
