These foods should probably go in the fridge
We all know what foods must go in the fridge – things like milk and eggs, meat and chicken. But there are others foods that probably should or could be refrigerated.
Here are a few examples from the Academy of Nutrition and Dietetics: tortillas, nuts, ripe bananas and maple syrup.
When you buy tortillas, look at the package. Chances are it will recommend refrigerating after opening, so that the tortillas left don't get moldy.
Nuts don't need to be refrigerated, but their saturated fat can turn rancid at room temperature after awhile. Those nuts are still safe to eat; they just won't taste as good. You can store nuts for up to a year in the fridge. It’s best to put them in a moisture-tight plastic or glass container.
Most of us keep bananas on the kitchen counter, but many times they ripen too quickly. Once they're ready to eat, you can put them in the fridge. Don't worry if the skins turn brown; they're fine to eat.
Maple syrup has a fairly short shelf-life life at room temperature, so it's best to keep it in the fridge.
