Wheat is a cereal grain that is one of the most widely grown and consumed crops in the world. It is a staple food in many cultures and is the primary ingredient in a variety of foods, including bread, pasta, and pastries. Wheat is rich in carbohydrates, particularly starch, and provides essential nutrients such as protein, fiber, and vitamins, particularly B vitamins. There are several types of wheat, including durum, hard red, and soft white, each used for different culinary purposes. Wheat is also a key source of gluten, a protein that gives dough its elasticity.
