Pineapple for cancer

I've been pondering over why so many people on a restricted cancer diet recommend eating lots of pineapple. I know the live enzyme in it is awesome for many things, but isn't the high Sugar content counter effective? Wouldn't bromelain do the job without the Sugar worry? This question is quite important to me since I dearly love pineapple and being now on a very very green diet I really would love the tiniest bit of variety, but the inconsistencies bother me. Does anyone who took pineapple and has cancer cancer have anything good to report, please? Tweet
