Sorghum is from Africa, but it is now cultivated in many countries of the world, including in Asia, Latin America and Europe. Sorghum is rich in nutrients and minerals, such as iron, zinc and calcium. It is also rich in fiber and protein, making it a food of choice for people who follow a vegetarian or vegan diet. In addition, sorghum is often used in the production of gluten -free products because it does not contain gluten.
