Wheat

Wheat is an item primarily obtained by farming.

Natural generation
Dungeon chests have a chance to contain wheat in stacks of 1 to 4.

Farming
When a fully grown wheat crop is harvested, it will drop 1 wheat and 0 to 3 seeds. The wheat crop has a total of eight stages from the time it is planted until it can be harvested. If the crop is harvested before it is fully grown, it will only drop seed(s).

Food
Holding wheat in your hand causes cows, sheep and mooshrooms that are close by to follow you, until you stop holding the wheat or create too large a distance between them, thus leading them to lose interest.

Wheat may be used to breed cows, sheep, and Mooshrooms by first herding two of them together and then the wheat on them to begin "Love Mode."

Wheat can heal a horse health or lower its temper by 3% when attempting to tame it. It can also increase a foal's grow by 20 seconds.

Efficiency comparison
Wheat is used to make several different types of food, but the benefit you get from each unit of wheat varies widely depending on what you use it for. This chart compares the number of hunger points you can expect to regain for each unit of wheat you use, depending on how you use it.

Video
Note: the narrator demonstrates at 0:56 that walking over wheat can destroy the crop and until the land. This is outdated: since version, wheat can only be destroyed by a player or mob jumping on it or falling on it.
