i assumed they were a speed food too, but we've probably just been brainwashed into think this by the media as they make out they're a superfood and celebrities seem to live off them.
ooh blueberries have a gorgeous taste but a lot of grocery stores get some nasty ones. The ones on offer at tesco at the moment are lovely big blueberries and they are lovely.
Not sure why they aren't a superspeed food but are really really good for you.
