I'm completely with Caryl on this one, and I think it does go back to Dave's post at the start of this thread that it's about education.
I grew up in a house of very little cash, my Dad drank most of the cash we did have and when my Mum became a single parent we were on benefits. Did we struggle, yes, but my Mum made sure I ate healthily. Of course we had treats but our day to day eating was very simple meals but using fresh ingredients - cheap cuts of meat from the butchers (I swear I had to go back and correct my typing there as I wrote 'meat' with a capital M
) and fruit and veg that came from the market stalls. We had very little cash but Mum knew what to do with it so we were fine! My Grandma turned 85 in July and she'll tell you the healthiest she has ever been was during the war when even though things were rationed she ate good ingredients. As Caryl said, if more people knew what to do with their money - regardless of how much of it they do or don't have -then more people would know how to eat healthy food for the same price (if not less) than what they're spending on crap. Of course not everyone would take that opportunity but I reckon enough would to make a difference.
