HI W - dissapointing that there haven't been any comments, but I have to add my rant- s/markets are not so super - they are in the business of maximising profit for the floor space they have.
That generally means brands have to pay for the shelf space for promotions, shelf positions and gondla ends, so the shopper is presented with the most advantageous products - not the best necessarily in terms of 'local' sourcing, freshness - think why all the veg is so cold when you feel it - cos its stored, packed, delivered and sold from chilled to maintain coclour, not flavour.
Over processed foods - 68 things in an ASDA frozen cheesecake, 47 in a Go Ahead red pepper slice - home grown, farm sourced goods are fresher,more nutirious, more flavoursome and more eco too if that fits the require,emts.
Small scale greengrocers often find the buyer for a s/market has taken the A grade goods and thats why their stock can seem not the best.
Have a look at the
http://www.bigbarn.co.uk site - put in your postcode and find a local box scheme for example that can provide seasonal fresh goods - & get your neighbours involved so there is more than 1 delivery made at a time which is nice and eco too.
If this is atopic you have some opinion about. have a rad of a couple of books - Felicity Lawrence's 'Not on the Label' & 'Shopped' by Joanna Blythman are exposes of the s/market business, plus there area few other titles that look at the impact of global food, farming practices and the supply chain that mihght open your eyes a bit.
It takes 20 tons of soy feed to get 1 ton of beef - easy to work out the costs of that in land use, fertilisers and other chemicals for the (poss. gm?) soy plants, CO2 emmissions for transport etc etc, bever mind the energy used to make the feed, as well as that involved in producing processed foodstuffs f
