Tips

 * This buff is 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.
 * On the flip side: An old proverb says "Give a man a fish, and you feed him for a day.  Teach the man to fish for himself, and you feed him for a lifetime".  While fish in Terraria don't quite last a full day, even a modest amount of fishing for other purposes can certainly 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.
 * Use this buff before boss fights or venturing into dangerous areas to gain a cheap and easy advantage. The movement buff makes it worthwhile even for exploring and mining.

Trivia

 * The Cooked Marshmallow is currently the only item to have the same duration on all platforms.
