Wheat is an ancient grain that is known to have originated in Southwestern Asia. It has been consumed as food for more than 12,000 years. It is a dietary staple for many regions around the world. It is estimated that approximately one-third of the world's population depends on wheat for their nourishment. Wheat, looked upon as 'the Staff of Life', has played a significant role in religion and has been a part of sacred rituals in many cultures.

Wheat flour is commonly known as 'aata' in India. It is made by grinding the whole wheat grains, also known as wheat kernels or wheat berries. Whole wheat flour includes every part of the grain i.e. the bran, the germ, and the endosperm. It is high in fibre and provides an immense amount of energy as it is an excellent source of carbohydrates.

Traditionally 'wheat atta' was made by stone grinding, a process that imparts a characteristic aroma and taste to the flour. Wheat flour is used to make Indian bread like chapati, naan, and puri. It is also used for baking whole wheat bread, healthy crackers, whole wheat pasta, etc.

The top 5 largest commercial producers of wheat are China, India, The United States, France, and the Russian Federation.
