Staple foods are plants that provided consistent caloric energy across seasons and generations. Unlike supplemental crops, these formed the nutritional foundation allowing populations to survive harsh winters, droughts, and food scarcity. They produced reliable yields without intensive labor, stored without refrigeration, and delivered concentrated calories for sustained physical work. This collection documents crops that once fed millions but have largely disappeared from modern agriculture.
