Not sure if you arlready done it, since I'm still feeding myself from a huge stack made in 0.6.5 but mana cookies.... One cookie, restores all the hunger and saturation for the simple effort of dropping a normal cookie inside a mana pool... I never worried with food anymore.
At the same time, once I had 10/10/10 seeds, I never worried with food since it grows faster then hunger depletes. Its just a question of making simple food(carrots) and always eating or making better food and eat once in a while (golden carrots). If food is not an issue on the pack, I would say just leave as it is and nerf a little the mana cookies. If you want for food to also be a thing... The usual combo of hunger overhaul/spice of life/pams harvestcraft resulting in 50 more food farms
