Processed food refers to items that have been altered from their natural state for safety reasons or convenience. This can range from simple processes like freezing or drying to preserve nutrients and prevent spoilage, to more complex changes such as adding preservatives, flavors, and other additives to enhance taste, texture, and shelf life. Canning, baking, and pasteurizing are also common methods of processing. While processing can make food more accessible and longer-lasting, some argue it can also reduce nutritional value and introduce less healthy elements like added sugar and sodium.
