A person’s state of health is affected strongly by two things:

1. Hereditary –the genetic make a person has inherited from their parents

2. Lifestyle behaviour–what a person does, and in particular what the person eats and the physical activity they do or don’t undertake

Poor eating habits are a lifestyle behaviour problem with all ages of people.

Good diet and proper exercise are different things. However, in order to achieve optimum health, attention must be given to both.

Sporting performance is mostly dependent upon genetics and proper training. Nutrition is an integral part of a proper training program. At an elite level, nutrition can be the difference between just a great performance and a medal winning one.

Many athletes have the desire to eat properly, but lack adequate knowledge and they may be influenced by inaccurate information. There is a whole industry involved in producing and marketing dietary supplements to athletes. Often supplements such as this are not what they claim.

Though there may be many guidelines to help distinguish reputable from disreputable products, the best way of eating correctly must always be to have a better understanding of nutrition.


The food an athlete eats provides him/her with essential and non essential nutrients, plus other substances that affect the body. A good diet will provide the body with the right nutrients to utilise energy; to build and repair tissues and to regulate body processes. On the other hand, a poor diet may lead to health problems and less than optimum performance.

  • Essential nutrients are those that must be eaten because the body cannot produce adequate supplies on its own. Essential nutrients include Vitamin B1, Vitamin C, Calcium, Zinc, linoleic fatty acid, and many more. Non essential nutrients can be taken in via food, but the body can also manufacture them. For example, glucose can be eaten directly, or the body can break down other substances to produce it. A balanced diet must supply the body with the essential nutrients in the correct quantities.
  • Nutrients are required in different quantities, and can be classed as macronutrients if they are required in large amounts. Micronutrients are only required in small quantities. It is important to remember that certain nutrients can be toxic if they are supplied in higher quantities than the body needs.

The Recommended Daily Intake (RDI)

In Australia, the RDI is a standard term which describes the intake of a nutrient necessary to be sufficient, or more than sufficient to meet the nutritional needs of the majority of healthy people in a population on a daily basis. RDIs vary with the individual, nationality and other factors. In other countries, similar indexes may have a different name – such as the RDA or Recommended Daily Allowance used in the USA. In Australia, RDIs have been set for 18 vitamins and minerals as well as energy and protein. There is no RDI for vitamin D as it is recommended that it be obtained by solar irradiation rather than dietary sources. RDIs for energy are based on estimates of energy requirements, depending on height, weight, age and sex. There are no RDIs for fat, carbohydrate and fibre, although national targets for consumption are generally used for reference.


A balanced diet will contain a wide variety of foods and thus provide a wide variety of nutrients. Obviously, what is a balanced diet for an endurance athlete in training will not be a balanced diet for an elderly, sedentary person. Different foods provide different nutrients and these nutrients are used for different functions:
