Diabetics have to watch their carbohydrate intake, and bread is a major player in a typical American's diet. Try to find a bread with at least 5 grams of fiber AND protein per slice so that eating it is validated by the nutrients it's carrying. Also avoid preservatives as they're not healthy either.
If you want to eat healthier to help overcome your Diabetes, but you just can't stomach fish without some pops of flavor on it, try capers! They're like olives in their flavor, but smaller and zestier. You can sprinkle them on any type of fish, I like to also add some slices of Spanish onion, and they take the place of sauce.
