What is vitamin C? Why do whe need it?
Vitamin C is one of several antioxidants shown to play a key role in
the prevention of many types of cancers.
Vitamin C maintains collagen,
a protein necessary for the formation of skin, ligaments and bones. It
also enhances the immune system, helps heal wounds and mend fractures,
and aids in resisting some types of bacterial and viral infections.
What are some good sources of vitamin C?
Citrus fruits (oranges, grapefruit, lemons, mangos, etc.) are great sources
of vitamin C, as are many green vegetables (especially asparagus, broccoli,
spinach, green peppers, and peas). Other good sources of vitamin C include
tomatoes, potatoes and cabbage.
What can happen if we don't get enough vitamin
Scurvy (hemorrages, loose teeth, gingivitis (bad breath), bone disease),
bleeding gums, increased chance for infection, colds or respiratory infections
can be unpleasant consequences of vitamin C deficiency.
