The refrigerator is not the go-to storage unit for all your produce. The following are types of produce you shouldn't keep in your fridge.
Tomatoes
A tomato is technically a fruit, but taste-wise, it's closer to a vegetable. The fridge is not the ideal place to store tomatoes. Store them there and your perfect tomatoes turn into a mealy disappointment. They'll still be good for cooking, but not the best for eating fresh. Instead store them on your counter (not in direct sunlight) and enjoy them when they're ripe.
Potatoes
Potatoes like cool, not cold temperatures. They do best at around 45 degrees F, which is about ten degrees warmer than the average refrigerator. Keeping them in a paper bag in a coolish spot (like a pantry) is best. Why paper? It's more breathable then plastic so potatoes won't succumb to rot as easily. And why not the fridge? Storing potatoes at cold temperatures converts their starch to sugar more quickly, which can affect the flavor, texture and the way they cook.
Onions
Onions don't come out of the ground with that protective papery skin. To develop and keep that dry outer layer, they need to be "cured" and kept in a dry environment like a pantry, which is not as damp as the refrigerator. Also, lack of air circulation will cause onions to spoil, as will storing them near potatoes, which give off moisture and gas that can cause onions to spoil quickly. Store onions in a cool, dry, dark, well-ventilated place. (Light can cause the onions to become bitter.)
Avocadoes
Avocadoes don't start to ripen until after they're picked from the tree. If you're buying a rock-hard avocado, don't store it in your refrigerator, as it slows the ripening process. On the other hand, if you have a perfectly ripe avocado that you're not ready to use, storing it in the refrigerator may work to your advantage by prolonging your window of opportunity to use it before it becomes overripe. So the bottom line on storing avocadoes is store hard, unripe avocados on your counter and store ripe avocadoes in your refrigerator if you're not going to eat them right away.
