Food or nutrition is the primary source of energy and
hence health for our body. Nutrition is the science that studies what and how
we eat and the effects it has on our health, such as what food or food
components may cause disease or adversely affect health. It also studies food
and dietary supplements that can help us to improve our performance, promote
our health and help in the cure or prevention of disease. For example, eating
food that is rich in fiber can reduce the risk of colon cancer. Also, supplementing
daily food intake with
vitamin C strengthens your teeth and gums and improves the immune system of
your body. Click Here to get your free E-Book |
