Stop Stashing These 6 Foods in Your Fridge – Here’s Why

Most foods are stored in the refrigerator to stay fresh. However, certain items can lose their quality when chilled. Here are six foods you should avoid storing in the fridge.

1. Potatoes

Storing potatoes below 4℃ (39°F) increases their sugar content, which can convert into acrylamide, a potential carcinogen. Exposure to light can also trigger the production of solanine, a toxic compound—store potatoes in a cool, dry, and dark place to keep them fresh.

2. Onions

Fresh onions stay best in a mesh bag, stored in a cool, well-ventilated area rather than in the fridge. Avoid storing them with potatoes, as potatoes can speed up onion spoilage. If you’ve already peeled an onion, place it in an airtight container and store it in the fridge’s vegetable drawer.

3. Garlic

Refrigerating garlic absorbs moisture, making it mushy and increasing the chance of sprouting or molding. Store peeled garlic in an airtight container with a layer of sugar at the bottom and a paper towel on top to extend its freshness.

4. Mayonnaise

Storing mayonnaise at low temperatures can affect its quality. Made with egg yolks, vinegar, oil, and salt, its components may separate if kept too cold. The ideal storage temperature is between 10℃ and 30℃ (50°F and 86°F) in a cool, dark place. Once opened, refrigerate it, but store it on a shelf near the door rather than deep inside the fridge to prevent oil separation.

5. Tomatoes

Refrigerating tomatoes halts ripening, causing them to wrinkle and lose their sweetness. Cold air reduces moisture and lowers their vitamin C content. It’s better to store tomatoes at room temperature between 25℃ and 30℃ (77°F and 86°F) but keep them out of direct sunlight, as temperatures above 30℃ (86°F) can destroy their nutrients.

6. Coffee Beans

Refrigerating coffee beans is not recommended, as they absorb odors from other foods, diminishing their aroma. The constant temperature changes when the fridge door is opened and closed can also alter their flavor. Store coffee beans at room temperature in a cool, dry place for the best results.
