Before purchasing canned food, study nutrition information on the label to find the content of sodium per serving.
Examine the cans before consuming. If it is dented, misshapen, or leaking, do not purchase. Bulging cans may most probably indicate that the contents are spoilt and can not be used.
Utilize potential spoiled canned goods in a way to prevent consumption by other people or animals.
For cans not date-stamped by the manufacturer, put date of purchase on your canned food yourself with a permanent marker.
It is better and safer to store contents from an opened can in a glass or plastic container that should be covered and kept in a refrigerator. Read the storage information on the label of the can.
Canned foods have already been cooked once, don't overcook them.
The liquid from the can also includes nutrients - use it for cooking rather than draining and adding water.
If you need to heat canned food in the container, remove the top to prevent pressure build-up. Cover the opened container loosely with a piece of aluminum foil. Place the can in hot water and simmer.
