*Grains* are small, hard, dry seeds (with or without attached hulls or
fruit layers) harvested for human or animal food.^[1] Agronomists also call
the plants producing such seeds 'grain crops'. Main types of commercial
grain crops are cereals such as wheat and rye, and legumes such as beans
and soybeans.

Harvested, dry grains have advantages over other staple foods such as the
starchy fruits (e.g., plantains, breadfruit) and roots/tubers (e.g., sweet
potatoes, cassava, yams) in the ease of storage, handling, and transport.
In particular, these qualities have allowed mechanical harvest, transport
by rail or ship, long-term storage in grain silos, large-scale milling or
pressing, and industrial agriculture, in general. Thus, major commodity
exchanges deal in canola, maize, rice, soybeans, wheat, and other grains
but not in tubers, vegetables, or many other crops.^[2]
