I have a better suggestion, please remove food altogether. I would even go as far as to say to remove ALL consumables.
In RPGs consumables serve to add some variation in gameplay, also serve to allow getting through seriously tough encounters at the highest difficulty levels, so having SOME potions and SOME scrolls is a good addition to an RPG, but I do not get all this hundreds of food, potion, grenade items business.
Arrows work great in this game (I did not test them in DoS II but they served fine in DoS: EE), since there is a ranger class that utilizes them. The rest is practically useless inventory bloat, as if the inventory was not bloated already.
I will digress here, but...
Besides, I am totally against item based character power structure. This structure is an MMO thing not an RPG thing. I would prefer my character to be powerful due to their level/abilities, their overall wisdom and experience, not because they have expensive jewelry. That is what I really like about DnD 2/3.5 low magic settings (low magic meaning item enchantments are not absurd). If you have a lvl 12 fighter wielding a basic +1 sword they will still destroy a party of level 5 dudes with magnificent items. That is how it should be. Or a lvl 18 wizard wearing nothing will still destroy a lower level party.
In DoS: II, for example, if I give my lvl 16 warfare person a lvl 3 sword he will be dead before he can even remove the physical armor of a much lower level character. That is nonsense, leveling up does nothing, I have to constantly pursue more and more powerful items.
