Wheat is a grain that has been one of humanity's most important food sources for thousands of years. Wheat grows as a tall grass with seed heads at the top, and when farmers harvest these seeds and grind them into flour, that flour becomes the foundation for bread, pasta, cereal, and countless other foods.

Think about your breakfast cereal, the sandwich bread in your lunch, or the birthday cake at a party. There's a good chance wheat played a starring role in all of them. Wheat flour mixed with water and other ingredients creates dough that can be shaped, baked, and transformed into everything from pizza crust to cookies.

The invention of wheat farming changed human history. Before people learned to cultivate wheat, they had to hunt and gather their food constantly. Once they could plant wheat fields and harvest grain, they could stay in one place, store food for winter, and build permanent towns and cities. Civilizations in ancient Egypt, Mesopotamia, and parts of the Middle East all depended on wheat or similar grains.

Today, wheat grows on more farmland than any other crop in the world. Different varieties thrive in different climates: some prefer cool, rainy weather while others grow best in hot, dry regions. When you see golden fields swaying in the wind during late summer, you're probably looking at wheat ready for harvest.
