The pear is a delicate fruit with varieties native to Europe and Asia. The popular buttery European pear varieties include Bartlett and the Comice. The crisper, milder-flavored pears comprise a variety referred to in the United States as simply the Asian pear. Pear juice is an effective, convenient method for consuming the nutrients pears provide, particularly when the sensitive flesh is blemished or overripe.
A 1-cup serving of pear juice provides 150 calories, or 8 percent of a standard 2,000-calorie diet. The caloric content is similar to a cup of orange juice that provides 110 calories. Most juices have a similar range of caloric content. The nutritional value makes drinking pear juice an efficient use of calories, compared with consuming a soda or a cup of coffee.
The effect of pear juice on blood sugar is largely related to its fiber and carbohydrate composition. The fiber in one cup of pear juice is 1.5 g, or 6 percent of the 25 g Food and Drug Administration (FDA) daily value. The carbohydrate content in the juice is 39 g, or 13 percent of the 300 g the FDA recommends. Fiber slows gastric emptying that propels carbohydrates from the stomach to the intestines. The fiber in pear juice helps mitigate any negative impact on blood glucose, such as raising blood sugar and causing imbalances that lead to diabetes and glycemic disorders.
The nutritional composition of pear juice includes trace minerals. One cup provides 32 mg of potassium, or about 1 percent of the daily 3,500 mg requirement, and .7 mg iron or 4 percent of the 18 mg daily value. Minerals are important, particularly during the warmer months when the body excretes them through sweat secretions. Replacing fluid and minerals with pear juice is convenient and healthy.
The vitamin C content in a 1-cup serving of pear juice is 3 mg or 5 percent of the 60 mg daily value. The body needs Vitamin C to protect cells from oxidation, a process that damages the chemical composition of cell DNA and cholesterol. The harmful results include disease and premature aging effects, including skin damage.
