VITAMINS & MINERALS
Vitamins are complex organic substances that act as regulators and
catalysts in the many chemical processes that occur within our bodies.
Though they are required in small doses, vitamins are vital for
healthy being.
Most vitamins cannot be generated by the body and
must be inclusive in a healthy diet. A poor diet can lead to vitamin
deficiencies that in the worst cases can trigger more serious diseases,
this is common in developing countries. Hence the recommended daily
amount or RDA of all vitamins should be strictly followed. Usually
eating 5 daily portions of fruit and vegetables and some lean meat
or oily fish is adequate. Vitamin supplements are another option,
but should be taken with care and not substituted for intake through
a healthy diet. The elderly, the sick, vegetarians, pregnant women
and children should take special care in ensuring adequate intake
of vitamins. Good health requires thirteen main vitamins that are
separated into two groups. Fat-soluble vitamins need fat to be transported
around the body and can be stored, whilst water-soluble vitamins
are easily absorbed but cannot be stored.
Minerals are inorganic substances that play a part in nearly all-vital
life processes. Formation of teeth/bone and nerve function are just
some examples. The two sets of minerals required by the body are major
minerals like sodium, potassium that are required in bigger amounts
and trace minerals like iodine and fluoride that are needed in small
doses.
Our complete diagram below presents the different vitamins and minerals,
their roles in the body, a good food source where they can be found
and the recommended daily amount (RDA).
