Healthy Food Habits
Health can mean different things to different people. Some people see being healthy as
being able to complete daily activities, others see it as being able to complete a marathon.
A person’s health changes all the time, depending on the
situation they are in and people they are around.
Physical health may change from optimal when well to
poor when sick.
Mental health can change by the stress caused by exams,
but is generally short-term.
Social health may chance when isolated from a peer
The World Heath Organisation (WHO) defines health
as physical, emotional, social, cognitive and spiritual
wellbeing not merely the absence of disease.
Spiritual - our sense of purpose and meaning in life.
Physical - the wellness of your body and absence of pain.
Emotional - the capacity to express emotions and adapt to a range of demands.
Social - the ability to relate to people.
Cognitive - the ability to think clearly and make sensible decisions to cope with life’s demands.
Our cultural identity and beliefs may impact on the choices we make to food and general living. Food choices can most certainly be influenced by religion, however, the cuisine traditional to each country tends to be dependent on the particular region of a country, its local produce, influences from neighbouring countries and immigration, and historical and economic conditions.

Nutritional supplements are foods that can be used to increase the amount of nutrients (protein, carbohydrate and fat) in your diet. They range from high kilojoule drinks available in supermarkets to specific formula to improve sporting performance.

how the supplement is taken?
how much needs to be consumed?

By law, labels on packaged food must contain the following information:
• the name of the food
• the country of origin
• the ingredients, which are listed in decreasing order by weight
• warnings about allergens
• the use-by or best-before date
• virtually all manufactured foods must contain a nutrition information panel
The nutrition information panel (NIP) tells you the quantity of various nutrients a food contains per serve, as well as per 100g or 100ml. It is best to use the per 100g or 100ml to compare like products because the size of the serving may differ.
Under labelling laws introduced in 2003, virtually all manufactured foods must carry an
The NIP currently provides information on kilojoules, protein, total fat, total carbohydrates and sodium. Saturated fat and sugar must be listed separately to total fat and total carbohydrate.
There are many fad diets around, especially in women’s magazines, which promise to help
you lose weight quickly and effortlessly. Many will help you lose weight but the weight loss
is only temporary and often people on these diets end up gaining more weight when they
stop the diet. This is known as the yo-yo effect. Typically a fad diet:
• promises a quick fix
• promotes a combination of foods
• implies the diet will change your body chemistry
• excludes or restricts food groups or nutrients
• make claims based on testimonials
Predict the short and long
term health impact of the
following on your health:
• Getting no sleep
• Not exercising
• Having no time to relax
• Not going to school
• Not eating

Whilst the obesity epidemic in the US may have plateaued, experts warn that Australia’s obesity crisis is far from over. In the US, the obesity rate has increased every year for the past 25 years. Government officials say that factors such as growing awareness and more realistic dieting targets have helped to stop the upward trend. Experts warn that several more years of obesity rate increases are likely before Australia reaches a plateau in the next five years. Australians are still behind the US in terms of obesity rates, but as a nation the gap is decreasing.
About 35 per cent of women and 33 per cent of men are considered obese in the US, whilst Australia’s obesity rate is closer to 16 to 18 per cent. According to experts the obesity rates amongst young Australians is of considerable concern. There are more cases of obese young people and the rates are climbing, people are getting fatter faster. While the number of obese Americans is around 76 million, experts say that it would be near impossible to have the number climb any higher than 40 percent. At the current rates the whole population of the US would have been obese by 2040.
In both the United States and Australia a person is defined as obese if their body mass index is 30 or more, as calculated from their weight and height.
