Preparing Human Sustenance Humans prepare food to sustain themselves and meet their dietary needs by combining various ingredients. This process involves selecting raw materials, such as fruits, vegetables, meats, and grains, then transforming them into edible forms using different cooking methods. People use a range of techniques, including boiling, steaming, roasting, frying, grilling, and baking, to alter the taste, texture, and appearance of their food. Many humans also rely on complex recipes, which are detailed instructions that specify the ingredients and steps required to prepare a particular dish.
