Many people, especially during the heat of summer, feel almost everything should be kept cool and the coolest place to store food is the refrigerator. For these 11 foods, refrigeration is not only unnecessary but may ruin the food.

If you're like me and you like your watermelon chilled, slice it up, put it in the refrigerator in an airtight container or tightly wrapped until chilled then serve. Same goes for tomatoes or other fruits or vegetables that shouldn't be stored in the refrigerator.

As for potatoes, whole uncooked potatoes with the skin on are perfectly fine outside the 'fridge. Potato salad, on the other hand, should be kept refrigerated at all times unless you want to subject yourself to a case of food poisoning. Go figure.
