4. Oatmeal
This might be considered by some to be one of the most boring foods on the planet. Oatmeal is something that most of us have been familiar with as a breakfast staple since childhood, and it really is pretty bland-tasting unless you dress it up a bit with things like sugar, honey, raisins, berries, nuts or cinnamon. The right addition to your oatmeal can make a world of difference when it comes to shoveling it down and just 3.5 ounces of oatmeal contains as much as 10 grams of fiber.
