Tips

 * On pre-1.4.0.1 platforms, this buff is simpler, but is still extremely useful as it is easy to obtain, extremely versatile, and has a long duration.
 * During Halloween, Pumpkins for Pumpkin Pie are plentiful, and even at other times the Dryad can supply Pumpkin Seeds to farm them. Other food items can be crafted or picked up from varied sources.
 * Alternatively, a modest amount of fishing for other purposes can provide enough fish to keep a player well fed despite the shorter duration.
 * Most players should carry a stack of "food" items, and try to keep the buff always active. The movement bonus alone would make that worthwhile, but in food is even more important, as it is required to regenerate health normally. In any mode, the small but broad boost to combat abilities comes in handy.
 * This is especially true in seed, where the player can die from starving.
 * Use this buff before boss fights or venturing into dangerous areas to gain a cheap and easy advantage. The movement speed bonus makes it worthwhile even for exploring and mining.
 * As of, the more powerful versions generally have shorter duration but are still fairly accessible.
 * For Food items that provide Exquisitely Stuffed, Burgers dropped from Crimeras and Eaters of Souls are the easiest ones to obtain from an enemy, lasting 8 minutes. Seafood Dinners crafted from uncommon to rare catches are easier to obtain, and last for 14 minutes. Golden Delight, crafted from golden critters, provide 48 minutes of Exquisitely Stuffed, the longest lasting buff of all Well Fed tiers.
 * Neon Tetra, Princess Fish, and Stinkfish should be converted into Seafood Dinners, despite that selling Seafood Dinners is less profitable than selling the fish, other fish of its rarity can be turned into a buff potion.
 * Food items that provide Plenty Satisfied are dropped much more commonly, most noteably Banana Split, dropped from most Pre-Hardmode Underground Desert enemies. The Bowl of Soup, Pumpkin Pie, and can be easily crafted from more common materials.
 * Food items that provide the Well Fed buff are the easiest to obtain, such as the Cooked Fish being crafted from plentiful catches, and from Bunnies.

Trivia

 * The Cooked Marshmallow is currently the only item to have the same duration on all platforms.
 * The buff icon for each food buff is a, a , and a respectively.
 * Roasted Duck does not give the Exquisitely Stuffed buff, despite its icon usage. Instead it gives Plenty Satisfied.
 * The stars depicted in the buff icons may be the Michelin Stars, a rating system given to high level restaurants.
 * Well Fed bonuses can be converted into an amount of corresponding to the buff duration by sitting on a Toilet.
