2. Bananas and avocados

Another bad combo of foods you should never store together is bananas with avocados. In most cases, if you are lucky, you might get a super discount for avocados because otherwise, they would become very expensive. And if you spend a lot of money on a specific food, you want to keep it fresh for as long as possible. In case you already bought them ripe, keep away from bananas since bananas contain a gas that promotes ripening.

To guarantee a longer life for both of the items, store them in your fridge apart from each other! This will slow the ripening process. In case your avocados are green, store them with the seed intact in an airtight bowl along with an onion slice.
