Biological Background: Apple was originated in Asia Minor. It has been cultivated for thousands of years and today is the most cultivated fruit tree in the world.
A typical medium-sized apple (212 g) provides 125 calories (most from fructose), 0.4 g protein, 6.6 g fiber, 244 mg potassium, 12 mg vitamin C, and traces of other minerals and vitamins.
Apple is one of the best sources of flavonoids and a good source of dietary fiber (pectin), which are responsible for most of apple’s disease-fighting properties. Flavonoids and pectin in apple help fight heart diseases (stroke and high blood cholesterol), cancers (breast and ovarian), and constipation. Apples also have mild antibacterial, anti-inflammatory, and estrogenic activity. In addition, apple can suppress appetite, thus having an apple before a meal can help control weight.
Eating Tips: Most of flavonoids and fiber are in the apple peel. And the colorfulness of an apple reflects the amount of flavonoids. Therefore, to get the most health benefit from apples, eat two bright-colored and unpeeled apples a day.
