With their pale flesh and sweet, juicy taste, pears are fragrant, delicious and nutritious. The U.S. Department of Agriculture recommends that you eat between 10 1/2 and 14 cups of fruit per week. A 1-cup serving of pear juice requires two whole, large pears. Drinking pear juice once or twice a week will help you meet your weekly recommended fruit consumption.

Macronutrients in Pears
Because of its high sugar content, almost 45 grams per serving, pear juice contains 386 calories per 1-cup serving. As a snack or addition to a light meal, however, this is still a low-calorie option. A 1-cup serving of pear juice is virtually fat free, with only 0.64 grams of total fat. It has a minimal amount of protein, 1.66 grams, and contains almost 400 grams of water. Juicing pears filters out the dietary fiber, so the 14.3 grams of dietary fiber in two large pears won't be available in the 1-cup serving of pear juice they produce. Pear juice has only 5 milligrams of sodium per serving, so consuming it won't add much to your daily sodium intake.
Potassium Content and Its Benefits
An essential mineral to your well-being, potassium builds proteins and muscle in your body. Your body also requires it to break down carbohydrates into glucose. As an electrolyte, it regulates the electrical activity in your heart as well as maintaing the acid-base balance. The recommended dietary intake of potassium is 4,700 milligrams per person. A 1-cup serving of pear juice has 534 milligrams of potassium, over 11 percent of your RDI.
A Natural Antioxidant -- Vitamin C
A natural antioxidant, vitamin C protects your body from damage from free radicals -- produced as your body breaks down food -- and toxins such as radiation and exhaust fumes. Excess exposure to free radicals or toxins can speed up the aging process as well as potentially cause cell death and damage to your DNA. In turn, this increases your risk of developing cancer or heart disease. Used in the production of collagen, Vitamin C helps maintain skin, tendon, ligament, blood vessel, cartilage, bones and teeth. It also helps with scar tissue production. A 1-cup serving of pear juice has almost 20 milligrams of vitamin C, or 22 percent of the dietary reference intake for men, 26 percent for women, 23 percent for pregnant women and 16.5 percent for women who are breastfeeding.
The Clotting Vitamin
Sometimes called the “clotting vitamin,” vitamin K aids blood coagulation. Without enough vitamin K in your system, you can experience abnormal bleeding and bruising as well as difficulty healing from wounds. Vitamin K also helps your body absorb calcium and is essential for maintaining strong bones and healthy teeth. A 1-cup serving of pear juice has a little over 20 micrograms of vitamin K. This provides almost 17 percent of the daily adequate intake for adult men and over 22 percent of the AI for adult women, including those who are pregnant and breastfeeding.
