Canned foods are very convenient since they make most fruits and vegetables available all year long. And, they’re so easily accessible. You’ll find them on supermarket shelves in every store. But, when buying them, remember to check the expiry date and ensure that the cans don’t look dusty or have torn labels, because that might indicate old stock. At home, practice the rule, first in, first out; this means you should use the oldest products first. The simple way to do this is by placing the newly purchased cans behind the same products you already have.
