13. Bananas
Bananas are grown in hot climates and retain their nutrients better when kept at room temperature. Putting them in the refrigerator will also slow down the ripening process that occurs naturally. Cell damage may even occur when bananas are kept at colder temperatures.
12. Chocolate
Lots of people put their candy bars and many other types of favorite chocolate in the refrigerator to keep them from melting or getting too soft. The biggest problem is that the taste may be altered after being exposed to the cold. What is called a “sugar bloom” happens after chocolate is taken out of the refrigerator and exposed to warmer air. This can ultimately cause a grainy coating to form and ruin the texture of the bar.
