According to the passage, vitamin C helps to ----.
Vitamin C boosts the immune system by strengthening
the action of white blood cells that destroy harmful
bacteria and viruses, such as cold and flu viruses. It is
also an important antioxidant, protecting the watery
internal parts of cells from the damaging effects of
excess free radicals, and it works in partnership with
vitamin E which protects the fatty outer part of the cells.
Moreover, vitamin C can help to prevent cholesterol
from becoming oxidised, a phenomenon now thought to
be the precursor to the furring of arteries – the reduction
of blood flow through arteries. High intakes of vitamin C
are also linked with lower levels of stomach cancer. In
addition, vitamin C improves the absorption of iron from
non-meat sources, so ensuring a regular intake is useful
if you are a vegetarian. Also, it has mild antihistamine
properties, thus allergy sufferers may find it helpful.
Furthermore, when we are under physical or mental
stress, vitamin C is depleted from our adrenal glands; it
plays a regulatory role in the production of the hormone
cortisone that helps us cope with the pressures of life.
