Yeah. I remember them saying there will be around 4 or 5 food types. (like appitizers, drinks, desserts, ect.) It would maybe be best to wait. Once it does come out, we can just add food-type sub-categories.
In that case, maybe it would be best to make several subcategories under the main category "Food"? That way, we'd be able to separate them by effect while still having them under a centralized category (eg. Ammo on the Terraria Wiki).
Edit: Just noticed that that was already the proposed plan. Good to know!
