Chapter 1 - Taking Charge of Your Health

How can I achieve good health?

Good health is actually quite simple.

The remainder of this chapterwill cover eight basic areas in
which we can maintain good health.

1. Nutrition

Nutrition is simply the study of what foods can help our
bodies to function at their best. The food we eat is one of the
most important aspects of health, as it has a direct impact on
the way we feel and perform. It provides fuel for the body to
run on. Energy from good food is after water, the body's
number-one necessity.

When you choose food lacking in essential nutrients your body
becomes deficient. An example of this is an iron deficiency. This
iswhere a person feels 'washed out' and tired. The body needs
iron to carry oxygen around the body, and a lack of iron means
the oxygen isn't carried around the body very well.

So, if nutrition is so important, what is a nutritious food?
Nutritious foods contain lots of essential nutrients (These are
substances that the body must get from food, because the body
is either unable to make it itself or unable to make enough of it).
Essential nutrients include vitamins, minerals (such as iron and
calcium), carbohydrates, proteins, fats and water.  All food
contains nutrients, but some foods contain more nutrients than
others. It's important to choose the most nutritious food possible
so that your body gets all the nutrients it needs to function
properly. Nutrition and healthy eating habits are covered in more
detail in chapters 2 and 3.
