No single food contains all the nutrients we
need to help the body work properly. So we
have to eat a variety of foods to get the right
amount. There are several main types of food
which if eaten in certain proportions will
provide a 'balanced diet'.
The average diet contains enough food for our
energy requirements. However not enough, or
too much, of a particular nutrient, or a diet in
the wrong proportions can lead to both short and long term health problems such as obesity or
heart disease, and may in general shorten our overall life expectancy. Maintaining a balanced diet
helps to maintain a healthy body and mind and helps build up the immune system.
