Nutritional changes
After adjusting for changes in the age of the population, fruit consumption stayed relatively similar between 2001 and 2007–08, with 59% of people aged 12 years and over in 2001 usually eating two or more serves of fruit a day compared with 57% in 2007–08. However, vegetable consumption that approached or met guidelines for this age group, went down in this time, with only 20% of people aged 12 years and over in 2007–08 usually eating four or more serves of vegetables, compared with 30% in 2001.
Fruit & vegetable consumption
Why do you think the consumption of beef & veal has decreased?

Why do you think the consumption of pork and chicken has increased?

Were we eating more meat per capita in 2008 than we were in 1979?

Sodium consumption
Breakfast
Social changes
Lunch
Dinner
Lets have a vote, how do you eat breakfast, lunch and dinner?
The average Australian consumes around eight or nine times more sodium than they need for good health (betterhealth.vic.gov.au).

Around 75 per cent of the salt in our diet comes from processed foods. Nutritionists recognise it may be difficult for many people to reduce their salt intake to the ideal level, given our current food supply (betterhealth.vic.gov.au).

Half of the Australian adult population have salt related health problems (saltmatters.org).

Fun fact: a bowl of corn flakes has the same amount of salt as one cup of sea water!
Sugar - NOT carbohydrates!

75% of the sugar we consume comes from packaged and pre-prepared foods and drinks.

Australians are the BIGGEST consumers of sugar in the world! At an average of 50 kg per person per year, Australian sugar consumption exceeds that of European countries at around 40 kg per year, the United States of America at 33 kg and Japan at 20 kg.

Does this surprise you?

Is sugar bad for you?

Economic changes
Household expenditure
Are you surprised?
The percentage of household income, spent on food during the 70's was around 23%.
That is: The average income was $172.35/week and $40.16 was the average food bill.

Predict the percentage spend on food during the 80's, 90's and 00's.
So what has changed?

Let's break it down!
70's 80's 90's 00's
23% 22% 21% 20%
Environmental changes
Every year, you throw away 200kg of packaging!
Packaging waste pollutes our air, water and soil. In fact, 1.9 million tonnes of packaging waste produces the same amount of greenhouse gas as 860,000 cars.
How much does our convenience really cost?
