Granola is not that bad but it’s no breakfast of champions. One cup contains 28 grams of fat and 560 calories before you add milk.
When it’s made with real ingredients it can be quite healthy, but let’s be real here. Most food manufacturers mass produce this stuff and they often cut corners to reduce production cost. So they alter them in a way that it isn’t healthy any more. You’ll find that most granola bars contain nuts and oats but with lots of sugar and oil added to them. And the way it’s packaged just encourages overconsumption.
