3. Diet Related Disorders
The major causes of death in Australia are linked to diet and lifestyle. Some people consume a well balanced diet while others do not. Poor nutrition and an unhealthy lifestyle are related to many disorders, including alcoholism, anorexia nervosa, bulimia, dental cavities, diabetes, heart disease and obesity. Making the right food choices can significantly reduce the risk of developing diet related disorders.
Many illnesses and health problems are directly related to our lifestyle and food choices. The term lifestyle refers to the foods we eat and don't eat., the leisure activities and hobbies we enjoy, where and when we work, our behaviours and habits. Over the past few decades, the lifestyles of of Australians have changed significantly. More and more people are recognising the dangers associated with sun exposure, the foods they consume and the alcohol they intake. A lot of people choose to exercise regularly. However, we still have a large percentage of the adult population who suffer from diet related disorders because of poor lifestyle and food choices. In many instances, these diet related disorders are completely avoidable.

Anaemia
Anaemia is a blood condition and is the most common deficiency disease in Australia, particularly in females. Estimates suggest that around one in five menstruating women and half of all pregnant women are anaemic. Anaemia has a wide range of causes, including certain diseases, conditions, and medications. Iron deficiency is the most common cause.

Anorexia Nervosa
One of two common eating disorders, anorexia is a condition in which a person refuses to eat sufficient food to maintain a minimum normal weight for age and height. The consequent wasting away has serious effects on many body systems, and may result in death.

Bulimia
Bulimia is an eating disorder marked by cycles of binge eating of excessive quantities of food, followed by purging through vomiting or use of laxatives or diuretics. The purging can seriously damage health. Unlike anorexia, a person with bulimia is rarely grossly underweight.

Dental Cavities
The incidence of dental cavities in the Australian population has reduced over the past decades, mainly due to improved nutrition, fluoridated water supplies and improved dental hygiene. Dental cavities occur when bacteria in the mouth convert sugars and refined starches from foods and liquids into acids. The acid that is produced in the mouth can dissolve the outer layer of tooth enamel, resulting in cavity.

Diabetes
Diabetes can be life threatening if not carefully controlled. It is expected to affect one in four Australians within the next few years. Diabetes occurs when there is too much glucose in the blood. If blood glucose levels are constantly higher than the recommended range, health problems can develop.

Coronary heart disease
Coronary Heart Disease kills one in three adult Australians and is the leading cause of death in Australia. It occurs when the arteries in the heart become clogged with fatty deposits that restrict the amount of blood that can be pumped through them-sometimes they even become totally blocked. This makes the heart work harder to pump blood around the body and places extra pressure on the heart.

Obesity
Obesity is a very serious problem in Australia- approximately two-thirds of the adult population are over weight and 20 percent are classified as obese. It is estimated that, if the current trend continues, by 2010, seventy percent of Australians will be above their healthy weight range. Too much food and too little physical exercise result in an increase in weight. Obese people are those who are 20 percent or more above their recommended weight for height. People who are obese are also at a higher risk of developing other diet related disorders.
