It was confirmed by Jeb/Notch that stacked food will be implented. It would mean some unbalancing, but I bet they'll take actions to keep things balanced. Another confirmed thing is that food won't directly heal you, but "indirectly".
If you see closely, there seems to be hunger or something where the damage of your armor have been, and also there is a long blue line under it, so that may be thirst
Dude, it has been confirmed that food would be made stackable. Also, why would they use too many items? They are the creators of Minecraft, doubtlessly they have their own tools.
That's a nice forum you got there.... It'd be a shame if something happened to it....
I also want squid and creeper meat.
Still, looks cool!
And STACKABLE MEATS.
amazing
