Can one eat a whole pineapple at a go? I ask this since I live by myself. When I juice the pineapple I atleast get 2 big glass fulls. When kept overnight in refridgerator, the juice doesnt taste as well the next day and also looks darker.. I want to know if its safe to drink 2 big glassfulls of pineapple juice at a time - I mean wont it spike the sugar levels?
