Worst Granola: Nature's Path Pumpkin Flax Plus Granola. This USDA Organic cereal isn't all bad—pumpkin and flax seeds pack 5 g of fiber and 6 g of protein as well as 450 mg of omega-3 fatty acids per ¾-cup serving. But at 260 calories, 10 g of fat (1.6 g saturated), and 10 g of sugar, it's far from the best choice to start your day.
