[Helper Mods] is the wrong tag for JFood, as it is game changing. [General] or [Big Mod] is more accurate. With farmland you have new [Mining], of sorts, then the items themselves could be considered [Weapons], [Armor], or [Utility]. If you build it up like Bio Industries, it's a [Big Mod] for sure. You might want to think about making JFood an expansion of Bio Industries, to avoid the work of fleshing out your own tree farm industry.
