It may be second nature to stash just about anything in the fridge, but this produce actually stays fresher at room temperature.

Whole Melons

The fridge can cut the number of antioxidants in half. A USDA study found that watermelons at room temperature develop nearly double the levels of compounds like beta-carotene (which promotes healthy skin and eyesight) than do refrigerated melons. Cool air stunts the antioxidant growth that occurs after harvest. Chill sliced melons to prevent bacterial growth.

Basil

If this tropical plant is stored below 40 degrees F, it turns black quickly. Keep on the counter in a shady place, and mimic placing flowers in a vase: Fill a glass with water and submerge the stems. Place a zip-top plastic bag over the plant to allow it to breathe and stay moist.

Potatoes

Cold temperatures convert potato starch into sugar. This results in a gritty texture and a slightly sweet flavor. Potatoes do best at 45°F (most refrigerators are set from 35 degrees F to 38 degrees F). Store them in a paper bag in the cool pantry. Sunlight causes chlorophyll to accumulate, turning potatoes green and sometimes bitter.

Onions

These vegetables need air circulation to stay fresh. Store whole onions in a hole-punched paper bag in the pantry. Don't keep near potatoes; onions emit gas and moisture that can cause potatoes to spoil quickly. Refrigerate chopped onions.

Tomatoes

Cool air alters chemical pathways in tomatoes, slowing those that contribute to fresh flavor and accelerating others that dull flavor. Store whole tomatoes on the counter for more delicious taste.
