Fact: a diet containing whole, fresh fruits and vegetables is one of the best for a healthy mind and body. Although true, it can be hard to keep food fresh at home for longer periods of time, and if you have no time to shop every few days, boxed and canned foods become appealing. We often hear about heavily processed frozen dinners and processed foods worth avoiding, but there are minimally processed foods that do pack a lot of nutrition and may be worth having in the fridge or cupboard.
