6. Nuts and Nut Oils
Almost all kinds of nuts (e.g., walnut, almond, pecan, cashew, sesame, Brazil nuts) will go rancid at room temperature due to the breakdown of their oils. They will last longer if refrigerated, or you can even freeze the whole nuts.
5. Bread Products
All kinds of bread products will last months longer when refrigerated or frozen, even the ones we do not think about going bad, like bread crumbs and croutons.
All kinds of rice, including basmati, brown, wild, jasmine and long grain, will last longer in airtight containers kept in the refrigerator. This prevents the rice from degrading or getting buggy.Related: How to Keep Milk at Its Freshest
