The bread aisle isn’t as visually stimulating as, say, a sorority house, but it has about as many options. The first thing to look for is the term “whole wheat,” which means the bread hasn’t lost anything to refinement. (If you check the label, the first item on the list of ingredients will be whole wheat flour. Breads labeled simply “wheat bread” are usually made with about 75 percent white flour and 25 percent whole wheat flour.) Whole wheat breads are darker in color and contain a good amount of slow-digesting, belly-filling fiber.
