I've read many articles listing the benefits of buying locally grown food and many of the benefits sound plausible. But today I read the following, which left my skepto-meter tingling (emphasis mine):
Did you know that the produce in the supermarket (whether it is organic or conventional) travels, on average, 1,500 miles from the farm to your plate? Not only is all that travel taxing on the environment, but it also gives the produce a chance to lose some of its nutritional value along the way.
Do vegetables, fruits or meats lose nutritional value between the time they are picked / rendered and the time they end up on grocery store shelves? Or is it that the mere act of transportation somehow affects the nutritional content?
Both propositions sound spurious to me.
