Really, the best way to get your carbs is from vegetables, fruit and beans. The OmniHeart study found that diets rich in veggies, fruits and low-fat dairy foods and low in sat fat, salt and sugar lowered blood pressure and LDL (the "bad" cholesterol). But each person in this study had only 4-5 servings of grains for a 2,000 calorie/day diet. That's NOT much bread, my friends. And sometimes, you just want to sandwich something.
Try thin, whole grain rolls like Pepperidge Farm Deli Flats or Arnold or Oroweat Sandwich Thins - they have 100 calories per bun and will let you stretch your whole grains budget further every day.
