Well, you have respondent bias. It's not like the entire population of BigFooty is posting in this thread. I know that 7 years ago when I was eating a ton of fast food, I wasn't exactly rushing around to tell everybody about my dietary habits.Wouldn't buy that for a minute to be honest.. You could argue that the fitter people in life would spend bugger all time on a forum, opting to be out doing something less sedentary.
And plus, there's no prerequisite to be fit/sporty/healthy just to be interested in a sport. I can't play footy to save myself yet I'm obsessed with watching it.
I would also say that the population isn't strictly divided into fatties and health freaks. There are some people who are just insanely healthy their whole lives. Most of my friends are like me - ate well living at home, ate like crap when they first moved out, then gradually cleaned up their diet as they started to get older and their changing lifestyle/metabolism caused them to stack on the weight. What our answer is depends on what point in our lives you ask us the question.
All comes down to relative cost though. That's much cheaper than Australia, but Australia has a very high cost of living all round. More instructive would be how it relates to things like the median wage, or the cost of processed foods. Fast food in Australia is very expensive compared to the US, for example, because of our high minimum wage.I haven't been to the States for a while to be honest. But I find fruit is pretty cheap here. Bananas for 50 cents a pound, mangos 65 cents each, pineapples for $2 and you can buy massive punnets of strawberries or blueberries for just a few dollars.
