Kellogg's Fiber Plus Cinnamon Oat Crunch
140 calories, 12g fiber, 4g protein, 9g sugar
This Cheerios-esque cereal is super-high in fiber, with a sweet cinnamon-coated crunch. The ingredient list is also surprisingly short for a mega-brand, with whole-wheat oat flour leading the list of fewer than 10 items. Kellogg's says the cereal is fortified with antioxidants, but we think you'll get more healthy micronutrients by adding some sliced fruit atop this oaty O.
