Canned food refers to food that has been processed, cooked, and packaged in airtight containers, usually made of metal or glass. The canning process involves sealing the food in the container and heating it to high temperatures to destroy any bacteria, yeasts, or moulds that may be present, thereby preserving the food for a longer period.
Canned foods can include a wide variety of food items, including vegetables, fruits, meats, fish, and soups. They are often used for their convenience, as they can be stored for long periods without refrigeration and are easy to prepare.
However, it is important to note that some canned foods may contain high levels of sodium or added sugars, so it is important to check the nutrition label before consuming them regularly. Additionally, some canned foods may contain preservatives or other additives that some people may be sensitive to or wish to avoid.
