"An
apple a day keeps the doctor away" is certainly no exaggeration, for the
mighty apple is indeed a storehouse of vitamins, minerals and many other
valuable substances. In fact, apple consumption has been associated with
reduced risk for a number of diseases including cancer, particularly lung
cancer, as well as cardiovascular diseases, asthma and type 2 diabetes. Apples
are rich in vitamin C and vitamin E, the content varying with the 7,000 known
varieties. Vitamins C and E are powerful antioxidants, which help to build
immunity. fight chronic diseases and slow down ageing.
Apples
are also an excellent source of disease-fighting soluble fibre in the form of
pectin. Its high pectin content helps lower cholesterol and acts as a laxative
by bulking the stool and maintaining intestinal balance. Pectin also helps to
bind toxic metals such as mercury and lead, and helps excrete them.
Cooked
apples are known to relieve diarrhoea, dysentery and colitis. One large apple a
day has been shown to reduce serum cholesterol levels by 8-11 percent.
The
pectin in apples supplies galacturonic acid to the body, which lowers the
body's need for insulin and may help in the management of diabetes. Apple
pectin helps in gelling and it is this property which helps in making apple jams
and jellies.
Apples
and apple juice are rich in phytochemicals (plant chemicals) including
flavonoids and polyphenols. Polyphenols such as tannins (tannic acid) are
potent enemies of viruses particularly herpes simplex virus. Two polyphenols -
phloridzin and phloretin xyloglucoside found in apples have not been found in
any other fruit.
Not
only are apples exceptionally rich in phenols, they also have the highest
concentration of "free phenols", which means that they are more
available for absorption into the blood stream. Quite impressively, the
anti-oxidant capacity of approximately one apple is equivalent to about 1,500
mg of vitamin C (although one apple has only about 5mg of vitamin C). A recent
study reported that risk of colorectal cancer was reduced by about 50 percent
on intake of more than one apple a day.
