Pears are a very healthy fruit that can come in many different shapes and sizes, depending on the region in which the pear is grown. This fruit grows on trees and has a juicy but grainy texture, with a skin of varying colors -- green, yellow and red are the most common shades--giving way to a white or cream-colored interior. Each pear provides energy to fuel your day -- 133 calories per large pair -- and contains vitamins that promote tissue health.
Pears can contribute a considerable amount of vitamin C to your diet -- roughly 16 percent of your daily required vitamin C, although the exact amount can depend on the size of your pear. Vitamin C is an antioxidant that protects your body's cells from damage by free radicals--oxygen-based compounds that can destroy the body's cells. Vitamin C also helps stimulate white blood cells, which work within your bloodstream to kill bacteria, contaminants and other germs that may cause illness.
The average pear contains 13 percent of the daily value for vitamin K. Vitamin K is vital to your body's efficient blood clotting. This reduces blood loss and the risk of developing an infection. However, too much clotting of the blood can create a dangerous internal clot that could severely injure and even kill a person. Vitamin K helps regulate this clotting to keep your blood in check and healthy. It also promotes bone health by regulating bone mineralization.
Vitamin A is present in trace amounts in pears, although this fruit is not considered a good source of the vitamin. Vitamin A is best-known for its role in vision, particularly night vision. Other roles of vitamin A in the body include supporting the proper function of the immune system, bone development, and the reproductive organs. Only 41 international are found in one pears -- a modest amount of the 2,333 international units needed daily for women and 3,000 IU for men.
