Human history
Climate affects what food people eat. This is because climate affects what foods can grow. If one food is easier to grow, people usually eat that food more often than other foods. Foods that people eat more of than other foods are called staple foods. Staple foods are usually grains or vegetables because they are easy to grow. Wheat, maize, millet, rice, oats, rye, potatoes, yams, breadfruit and beans are examples of different staple foods from around the world.
