A apple a day provides respectable amounts of insoluble and soluble fiber. 1 large apple supplies nearly 30 percent of the minimum amount of fiber specialists say must be consumed every day. Approximately 81 percent of the fiber from the apple flesh is soluble, most of it a form called pectin. Studies suggest that pectin and other soluble fibers are successful in lowering cholesterol levels.
Fresh apples have some vitamin C and some potassium. When apples are processed into apple juice or applesauce, however, almost all their vitamin C is lost (though the potassium is kept ). Commercial brands of apple juice are often fortified with vitamin Cand occasionally with calcium as well.
Apples are rich in the antioxidant quercetin, and crimson apples contain a polyphenol called anthocyanin. Researchers theorize that these phytochemicals could be beneficial for health, however as yet nothing has been proven.
The apple is salty, succulent, and non-sticky, making it a good tooth-cleaner and gum stimulator. However, you should still brush your teeth or rinse your mouth with water after eating an apple because of the acids in the juice.
