I remember it was massive in the 1980s.
No one seems to talk much about fibre now. I wonder if that's because of the carbs?
I've just found myself looking up high fibre vegetables. I used to eat wholemeal pasta and brown rice but DH turns his nose up ( he will eat wholemeal bread ) so I have drifted into white pasta etc.
Maybe fibre is the answer and will make a return to diet fashion?
