All Things Considered, Canned Foods Are The Cheapest Source Of Nutrients

A U.S. study that compared the cost of obtaining key nutrients from various sources found that canned foods are almost always more affordable and convenient. The “market-basket” study took into account not only nutrients, but also price, waste and preparation time of canned, fresh, frozen and dried varieties of some common foods. Canned foods almost always were the cheaper source. For example, when preparation time of pinto beans is taken into account, the canned variety costs $1 less per serving than dried beans, because of the time it takes to soak and cook the beans before serving.
