LOW CARB & WHOLE-GRAIN BREADS: Lower-carb breads and tortillas can be a great source of fiber; look for those with at least 4 grams of fiber per serving. Look for 100 percent whole-grain bread (the term “multigrain" doesn't ensure it is all whole grain; check the ingredient list). Spread your toast with two tablespoons of a natural peanut butter for another 1.9 grams of fiber.
