Mitsubishi's vitamin-boosting fridge

Among the slew of new household products Mitsubishi has just announced are several refrigerators that will boost the vitamin C content of your vegetables by 10% during storage (though not if you leave them in there for a year or two, we presume). The trick is that instead of plunging your legumes into total darkness the "Delicious Vitamin Boost Light Power Vegetable Compartment" uses coloured LED lights at frequencies that don't "stimulate germination", and they have some graphs and photos of a cabbage to prove it works.
