GREENSBORO, N.C. -- On average, every American throws away about $2,200 worth of food each year.

Here are the five most commonly wasted foods and found ways to make them last longer.

Herbs - To make your herbs last longer, snip the ends off and put them in a vase in the kitchen. If they start to go bad, freeze them in ice cube trays filled with olive oil.

Bananas - If you want to make bananas last longer, separate them from the rest of the bunch then wrap their stems in plastic wrap. This prevents gas from riper bananas from getting to the less ripe ones.

Avocados - It doesn’t take avocadoes long to go bad. To make them last longer, slice them in half and brush them in olive oil. That will keep them from coming into direct contact with the air which ruins them.

Milk - Pour milk out of the carton and into a glass container. The glass gets a lot colder, so it will last longer.

Eggs - Finally watch where you place those eggs in the fridge. The door gets too warm, so keep them on the main shelf instead.
