Breads & Rice can be classified into eight different types, based on the effect they give you upon use. The first type is Snacks, they give you a temporary (3-5 minutes) food effects on HP or MP healing. The second type is Breads, which offer some Hit Points and Vitality, good for low-level jobs (levels 1-20). The third type is Sandwiches, they offer a good amount of Hit Points and Vitality plus other stats, recommended for a tank or melee job. The fourth type is Buns, small tastey snacks which are filled with curry (giving very large bonuses to strength and attack power), thus giving them effectivly the same bonuses for a shorter, more manageable duration. The fifth type is Rice Balls, they are specifically made for the Samurai (though Ninja and Monk can benefit too). The sixth type, Rice Dishes, has more stats than a rice ball, allowing it to be used by more attack jobs and Rangers. The seventh type is Pasta, these dishes can only be made by a chef who has the Noodle Kneading ability. Pasta dishes are excellent melee food (best for Monk and Warrior jobs), with stats including Hit Points, Attack, and Store TP. The eighth type is Pizza, large meals which grant bonuses to more than one favorable stat at one time (most notable, bonuses to both Accuracy and Attack), but have less potent bonus to either specific stat as compared to other foods.
All Breads & Rice are stackable (with few exceptions).
