Granola bars
Although rich in nutrients, some granola bars are also rich in added sugar. According to the Nutrient Database, most popular bars contain from 15 to 30 g of sugar per serving. On the other hand, if chosen properly, snack bars are a perfect way to kill hunger and avoid overeating since they are pre-proportioned and contain a lot of vital nutrients. A perfect bar should have at least 3 g of fiber, 5 g of protein, and less than 10 g of sugar.
