The refrigerator is a great invention in many ways. Many people are in the habit of putting foods into the refrigerator, thinking it will make their food last longer. But what exactly should or shouldn't be stored in it? Here's a great list to find out what they are.
1. Bananas
Bananas retain nutrients better outside the fridge, they should never be placed inside the refrigerator. The cold temperatures actually slow down the ripening process of the bananas, while the moisture and darkness of the fridge will only facilitate rotting.
2. Avocados
If you purchased an avocado that’s not ripen, you should not place it in your refrigerator. Since they will need time to ripen, keeping in the cold cooler will deter and impede that process. Also, placing the avocado in your fridge should only be done if the avocado is already ripe and you won’t use it right away.
3. Onions
Onions should never be stored in the refrigerator. Refrigerators are quite moist places and if you store your onions in the refrigerator you might notice that they become quite soft and mushy after a while. Onions are stored best in cool and dry places.
4. Coffee
Refrigerated coffee might stay a little fresher a little longer than coffee stored on your kitchen counter but the refrigerated coffee will taste bad.  The best temperature for coffee is room temperature.
5. Bread
If you purchased an avocado that’s not ripen, you should not place it in your refrigerator. Since they will need time to ripen, keeping in the cold cooler will deter and impede that process. Also, placing the avocado in your fridge should only be done if the avocado is already ripe and you won’t use it right away.
6. Hot Sauce
The vinegar in most hot sauces will be enough to stop any bacteria or mold from growing. Dig it out from the back of your condiments shelf and give it a spot with your cooking spices.
7. Tomatoes
Tomatoes will lose all their flavor in the fridge. What’s a bigger crime than that? The cold air in the fridge stops the ripening process, and ripening is what gives tomatoes more flavor. The fridge will also alter the texture of the tomato.  Keep tomatoes out in a bowl or basket on the counter.
8. Nuts
The cool temperature of your refrigerator can seriously damage the nuts’ taste. The best way to store nuts is to put them in an airtight container and keep them in a cool, dark place like the pantry or a cupboard. When properly stored, nuts can generally last for up to a year.
9. Honey
Frozen honey is an underrated snack. But at merely cool temperatures, they crystallize and become lumpy. Honey almost never spoils, so feel free to store it at room temperature for as long as you want.
When you check the foods inside refrigerator, do not forget the water filtration system. Filters can only continue to provide the best protection if they are regularly changed. To ensure your water treatment system is performing effectively, use the proper replacement cartridge and change your filter at the recommended interval.
