What's the point of entering fibre amount?

Sorry if this is elsewhere but I can't find the answer! Every time I enter the fibre info into the Ww website or my iPhone it never ever makes a difference to the points value. Does anyone know why we need to include it as it has no bearing on the points!

I'm not too sure hun only that fibre is one of the most if not the most important part of our diet it keeps us going fuels the body so maybe the higher the fibre the better it is for us? i don't know maybe they just wanted to highlight the fact that fibre contect is important lol
