Seems like everyone is mad about losing weight these days  if it isnt another government message on obesity, or calorie counting in restaurants and fast food joints  the message is forever we have to eat more sensibly.
Slimming World magazine  Stalker gets it on subscription, not  has a special rating for food stuffs, called syn values. Geddit?
Anyway mushrooms of all varieties come in Syn free! Woo hoo. So you can eat as much as you like of any mushroom.
Hopefully that piece of info ought to boost demand for the produce amongst the ever burgeoning slimmers out there.
Stalker goes with the statistics on slimming  most slimming regimens show weight loss, followed by a return to initial weight when regimen peters out. Pointless.
