How healthy is granola bar?

Is granola bar healthy? It can fit a healthy diet in small amounts. Granola bar scores 17/100 on the HowHealthyIs Score: 100 g provides 471 kcal, 97 mg magnesium and 10 g protein. Hard granola bars contain oats but are usually bound with sugar and oil, so they are closer to a cookie than a bowl of oats. Source: USDA FoodData Central.
