A surprising fact was gleaned from the BBC programme, "Britain's Favourite Foods" last night.
Where we can synthesize Vitamin D in our skin, when it is exposed to sunlight, apparently so too can mushrooms even after they are picked!
Mushrooms are grown in the dark but when exposed to sunlight they synthesize vitamin D.
So what did I do today? Yep, popped out bought some mushrooms and left them in the sun for an hour. Excellent to feed son who hates going in the sun. Mushrooms on the menu tonight then!
