Here is a no-brainer.

You need to keep eggs and milk in the refrigerator.

Me, personally, I enjoy an ice cold diet cola beverage. Don't forget the butter and ketchup.

Of all the things to put IN the fridge, there are plenty things to NOT put in the fridge, CBS News reports. It either makes them rot faster or makes their taste or appearance change.

"I think we assume everything will do better in the refrigerator, but that's not really true," chef Rachel Reuben, of Food Fix Kitchen, told CBS News.

Cold can keep many fruits and vegetables from going bad, although that does not affect taste or their health quotient.

I pretty much knew that most fruits shouldn't be cooled.

But potatoes? I didn't know that.

See, you learn something new everyday.
