Vitamin C, also known
as ascorbic acid, is a water-soluble antioxidant vitamin that helps control
infection, neutralize free radicals, and aid in the body's absorption of iron.
It also helps to make collagen, which is vital to the health of teeth, gums, bones,
and blood vessels. Unlike most animals on the planet, humans are
incapable of manufacturing their own source of vitamin C, so it's one
area of nutrition that requires daily attention and "restocking."
Good sources of vitamin C include any food that contains at least ten percent
of the recommended daily allowance per serving, and the wonderful news for anyone
aiming to increase their intake of vitamin C is that this covers a vast range
of healthy food, so it won't be difficult for you to increase your intake of
vitamin C.
Learn about vitamin C. Vitamin C is an important micronutrient in the human diet. It has a role in sustaining memory, helping prevent cell mutations and premature aging, preventing oxidation of fatty foods, and supporting the immune system.
·
Some people believe that
vitamin C cures or stops the common cold, but there is no strong scientific
evidence proving that this is true. What is more likely is that through its
immune system-boosting power, vitamin C provides extra defense against
cold-causing pathogens, so it may ease the cold and perhaps shorten
its duration, but it's not likely to prevent it.
Understand
the role between diet and vitamin C intake. Most people should be able to get adequate vitamin C
from a healthy, nutritionally
optimized diet. If you're eating nothing but fast
food, you probably aren't going to get a beneficial amount of vitamin C as part
of your diet. However, simply changing your diet for the better can help you
increase vitamin C intake.
·
Since vitamin C counteracts
some of the inhibitors in foods, such as phytates in whole grains and tannins
in teas and coffee, increasing your vitamin C intake can also help
optimize your diet for a healthier lifestyle.
Be aware
of the relationship between vitamin C and stress. Stress can be
brought about due to a depletion of vitamin C, and ongoing stress uses up vitamin C
rapidly, so eating foods high in vitamin C or taking a vitamin C
supplement when you are feeling stressed can be a positive contribution to your
diet and well-being. If you are aware of what you are consuming and the
micronutrients that those foods contain, you can adjust your diet to ensure
that you are getting enough natural vitamin C.
Notice the signs of possible vitamin C deficiency. While you should always raise health concerns with your doctor or health professional directly, the following signs can accompany a vitamin C deficiency: bleeding gums and nose, poor healing of cuts, fatigue, and lowered immunity to infection. These symptoms do not necessarily indicate a vitamin C deficiency, but you can speak with your doctor if you are concerned.
·
A severe deficiency of
vitamin C, in fact, can result in a disease called scurvy, which is caused when
your body cannot produce collagen or absorb iron due to a vitamin C deficiency.
·
While fewer people in
developed countries suffer from vitamin C deficiency to this extent, its onset
can be very fast if vitamin C is not in the diet for about four weeks.
·
Those susceptible to scurvy
include the elderly, illicit drug users, alcoholics, the mentally ill,
dependents given inadequate care, those suffering from eating disorders such as
anorexia or bulimia, smokers (smokers need more vitamin C to deal with the
added stress on the body), and fussy eaters
