It is confusing. SW have this thing about fresh food being "processed" which is why they syn fruit when its cooked as its gone through a "process", but is mashing a process?
We are not adding anything to it, you are keeping the fibre in it so it cannot be compared to juicing an orange where you keep the sugar and lose the fibre. Nonsensical really.
Carry on as normal is what i say. There are way many other things to ponder.
