Eggs - If they are farm fresh - a same day or 24 hours old out of the bird - out of the fridge for 5-7 days. Then in. Commercial eggs are washed, and the protective coating is removed. Ones from the grocery chain, when I buy them, go straight into the fridge.
Butter - technically, you don't have to store refrigerated, but if you don't use it often, it can go stale.
Peanut Butter - Same as butter, but oils generally go stale unless cold. My nuts(!!) are always refrigerated. Peanut butter, when cold is hard to spread, so many keep it out. We don't eat it that often, and might last months in the refrigerator. I like the nuke machine for that. Works for ice cream too.
Vegetables - which ones? Generally IN, except tomatoes, but they are technically fruit. Also depends if it's organically grown or commercially manufactured. Each is different in my experience. Commercial baby spinach in the plastic crisper lasts longer than my farmer's market spinach. Not sure why.
Fruits - again, which ones? Generally IN. Anything that isn't ripe stays out. Apples can hang out a while, I think.
Condiments - which ones? How often do you use them? Mustard? Mayo? Ketchup (don't eat the stuff. At. All)
Much of this depends on how ripe the fruit is/ are.
Bread - Depends on the quality of the bread, and if I bought it freshly made or a day old. It also depends on what kind of bread. Sour dough gets sour fast. Refrigeration slows it down, as far as I understand. Generally, it goes in after about 4 days to slow the mold process. Sometimes I'll freeze bread in portions.
In the end, I live in a smallish apartment with limited space, so most of what I buy gets eaten rather quickly. Also, each thingie has different method of refrigeration. My lettuce last forever wrapped in a cloth napkin and placed in a produce bag in the "crisper." With the root, I should say.
