Introduction

Corn, also known as maize, is one of the most widely grown crops in the world. It’s a staple food for many cultures, providing essential nutrients like carbohydrates, fiber, and several important vitamins and minerals. In this article, we’ll delve into the world of corn, exploring its history, nutritional value, uses, and more.

History of Corn

Corn has been a vital part of human civilization for over 9,000 years. It’s believed to have originated in Central America around 7,000 BCE, where it was first domesticated from teosinte, a wild grass-like plant. The ancient Mesoamericans considered corn a sacred crop, using it not only as food but also for ceremonial and medicinal purposes.

Spread of Corn
