Nutritional Advice

Nutrition is the art of balancing what we eat, with what our body needs to run, repair and grow.

If you see the body as lots of little engines, that either work as a team or independently, it is about which fuels they all need. If we put in the wrong fuels it will not work well, if we use poor quality fuels then it will not respond as well, and if we use no fuels it will stop.

The various types of fuel our body requires are Vitamins, Minerals, hydrocarbons, water, enzymes, fats and amino acids. Different foods we eat have different combinations and concentrations of the above. Being fit and active, does not necessarily mean you are healthy. So let’s look at this in more detail.
