Where has the taste gone?

A few weeks ago my daughter brought back so carrots that a friend of hers had grown on his grandfather's farm. They looked awful - twisty, curly and decidedly unappetising. Until you tasted them. Real old-fashioned carrot taste which was absolutely lovely. Wind forwards to today. Carrots which looked gorgeous from Tescos, lovely orange look but they tasted of absolutely nothing. Literally nothing. I could have been eating hot cardboard. Supermarkets have been brilliant at bringing us cheap food but at what cost (and I am going to ignore here issues such as carbon miles)? The loss of taste in what we eat has been considerable - the supermarkets assumption that looks are everything (and to be fair I am not certain who is pushing this - is this consumer or supermarket driven?). I want my food to taste of something .. so please ...
