Once upon a time (and not so long ago) Australians prided themselves on being fit and healthy, these days our country is ranked as one of the fattest nations in the developed world. More than 17 million people are considered overweight or obese, with a population of only 25 million that is an alarming statistic. There are fast food restaurants everywhere though we don't have the range in chains that the US does. The big three here are McDonalds, KFC and Hungry Jacks (Burger King).
The over reliance on fast food is a crying shame because we do produce some great quality food in this country. Things are changing though. More and more I see imported vegetables and fruit in the supermarkets as the local producers are out-competed by overseas suppliers. The two big supermarkets in this country control 80% of the grocery market and have no loyalty to Australian brands, in fact the two of them have their own low-cost homebrands which again price smaller companies out of the market. Grain-finished meat is becoming more prevalent and I wonder how long it will be before we start seeing feedlot raised cattle becoming the norm.
Fortuntately there is still some local support for small farms/producers and farmers markets are popping up everywhere, so it's possible to eat very well if you choose. As for cost, I actually think I'm spending less on food since switching to primal eating. Lamb can be very expensive, strangely enough in a country which produces so much of it, but I've not noticed grass-fed beef, free-range pork etc to be more expensive than other more conventionally raised meat.
And not sure what to make of your comment about most Aussies being so beautiful...certainly not something I've ever noticed!
