7 foods you should never buy organic

There are several reasons why it's best to buy organic, but buying organic may not always be best!

You might be used to paying extra for avocado, but don't buy organic. According to Cheat Sheet, their thick skin protects them from pesticides.

The same goes for pineapple, cantaloupe, and kiwis. Lisa Lee Freeman, a savings expert at Flipp, says never buy organic seafood either -- because organic seafood is farmed, not caught, wild-caught fish is healthier.

Pests don't like the bitter taste of asparagus, so it's less likely to need pesticide protection. It's also why Cheat Sheet suggests not buying organic onions.

So, what should you buy? Freeman suggests buying grass-fed meat.
