I was looking for some fresh food on OzBargain and all I found was Meys Meats.
Elsewise, the food section is choc-a-bloc with processed junk food. Does this reflect the proportion of processed foods we are actually eating?
What are OzBargainers eating in a week in fresh vs fast foods? If lunch and dinner = 14 meals, what is your mix, and how can you afford it?
What do you define as 'fresh' food? Going by definition, all food in the supermarket is technically decaying. In fact, much of it is frozen from over a year ago.
Try to find local grocers rather than large supermarkets for fruit & veg. The quality and availability varies on a weekly basis but the prices are significantly cheaper.
If you want really fresh, there's pick-your-own orchards/farms to indulge in, as well as regular farmers markets for fresh produce.
