Seasonal food

Seasonality seems to be the current buzz word of all in the cheffy community - you've almost certainly heard some guy who has been given a badge by a company that makes tyres going on about eating "local, seasonal produce". Well that's fine if you live in Provence or Emilia Romagna, but where I live is covered in about 3 feet of snow for half of the year. "Fuck you Fizzee, you moaning old arse" I can hear you saying, and that's fair enough, but this whole seasonality/local thing is way over the top-if I had to do that i'd be eating nothing other than root veg in the winter and no fruit at all until about May, I'm no expert but that doesn't sound overly healthy.
