Fresh pears offer dietary fiber, much of it in the form of Pectin. A pear weighing 166 grams provides 2.32 grams of crude fiber, and 4 grams of dietary fiber, of which 41% is pectin. Fiber contains no calories, and is a necessary element of a healthy diet, helping to sustain blood sugar levels and promoting regularity. High fiber diets may also help reduce the risk of colon cancer and can help reduce serum cholesterol. Pears are a good source of natural fiber.
