Cereal
Grasses cultivated for edible grain, global staple foods.
Cereals are grasses of the family Poaceae cultivated for their edible grains. They are the world's largest crops and serve as staple foods, including rice, wheat, rye, oats, barley, millet, and maize. The term 'cereal' derives from Ceres, the Roman goddess of grain crops and fertility.

Lore & Background
In China, farmers cultivated rice and millet using human-made floods and fires, and soil conditioners like manure, fish, compost, and ashes were used independently in Mesopotamia, the Nile Valley, and Eastern Asia.
Reader's Guide
Cereals are fundamental to human civilization, providing the majority of dietary energy and essential nutrients worldwide. Their domestication enabled agricultural surpluses, leading to complex societies and urbanization. However, high-yield varieties often have lower nutritional quality, being high in carbohydrates and deficient in essential amino acids, fatty acids, vitamins, and minerals. Cereal farming has substantial environmental impact, often involving high-intensity monocultures, but sustainable practices like no-till farming and intercropping can mitigate harm. Reductions in cereal production significantly affect global energy and micronutrient availability, including iron, zinc, magnesium, phosphorus, thiamin, and riboflavin.
Did You Know?
- The term 'cereal' derives from Ceres, the Roman goddess of grain crops and fertility.
- Cool-season cereals like rye and barley are hardy and can be planted in autumn, becoming dormant in winter.
