Pears have no cholesterol, sodium, or saturated fat. They offer a natural, quick source of energy, due largely to high amounts of two monosaccharides: fructose and glucose, plus Levulose, the sweetest of known natural sugars, found to a greater extent in fresh pears than in any other fruit.
A pear is a nutrient dense food, providing more nutrients per calorie, than calories per nutrient. Carbohydrates make up 98% of the energy provided by a pear, and carbohydrates are helpful in weight reduction diets because they contain half as many calories as fat.
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.
Fresh pears offer potassium; 210 mg in a medium size pear. Although it is an element lost easily through dehydration or perspiration brought on by active lifestyles or strenuous exercise, potassium is necessary for maintaining heartbeat, muscle contraction, nerve transmission, as well as carbohydrate and protein metabolism. Replenish potassium by eating fresh vegetables, fruits or legumes containing high potassium content - pears are an excellent choice.
Fresh pears contain Vitamin C. One medium size pear provides 7 mg, or 10% of the RDA for Vitamin C. As one of the antioxidant vitamins, Vitamin C is essential for normal metabolism and tissue repair, helping prevent free radical damage the destructive by-products of the body's metabolic process. Vitamin C improves the immune system and promotes healing of cuts and bruises and guard against a number of infectious diseases. Fresh pears are a good source for Vitamin C.
