The Pros
Canned food 84% of Americans prepare or eat meals made with canned foods at least a couple times a month.
Price. Canned food is cheap. This is the most obvious benefit of eating canned food, and a perhaps the main reason why students on a low budget eat canned vegetables and fruits regularly. The price benefit of canned food is particularly obvious during winter months when most vegetables are out of season and will have to be shipped from abroad.
Convenience. Fresh vegetables and fruits have a hard time beating the convenience canned foods can offer for those with busy lifestyles. Whether you're a busy parent or just an active person, keeping canned beans and vegetables on hand can let you quickly and spontaneously prepare soups, stews, and even salads
