For example, you are hungry and looking for a snack. Two options are the donuts someone brought to work or an apple you brought from home. The apple has around 80 calories and lots of vitamins, fiber and phytochemicals. The donut has about 200 calories. It does not have many nutrients or fiber. The donut will not keep you feeling full because it has only about one gram of fiber. The apple will keep you feeling full longer as it has more grams of fiber.
