This lecture discusses staple foods worldwide, their nutritional importance, and common substitutes for key crops.

Definition and Role of Staple Foods

  • Staple foods are regularly consumed foods that provide energy, mainly through carbohydrates.
  • Carbohydrates are the body's main energy source, similar to fuel for cars.
  • Eating only one staple food does not provide all required nutrients.
  • A varied diet is necessary for complete nourishment.

Common Staple Crops Around the World

  • Cassava: A root vegetable staple in Latin America, the Caribbean, and Africa; must be cooked and mashed for consumption.
  • Corn: Eaten as a vegetable or processed into oil, syrup, and starch; grits, cornmeal, and cornflakes are common derivatives.
  • Plantains and Bananas: Belong to the same family; plantains must be cooked and are starchier and less sweet than bananas.
  • Potatoes: Grown and consumed worldwide; available year-round and come in several varieties.
  • Rice: Staple food for over half the world's population.
  • Sorghum: Main grain in Guinea, used for bread and sweet syrup.
  • Soy: Majorly produced in the US, Brazil, and Argentina; used in beverages, tofu, and meat substitutes.
  • Wheat: 65% of harvested wheat is used for food; used in breads, pasta, and noodles.
  • Yams: Staple in West Africa; boiled and made into dough called fufu, which can also be made from cassava and plantains.
