Should you refrigerate natural peanut butter after opening?

Refrigerating natural peanut butter after opening is a very smart practice. Because pure peanut butter lacks the artificial preservatives and food chemicals found in processed brands, the natural oils can eventually go rancid if left in a warm environment for too long. Keeping it in the fridge preserves its fresh taste and extends its shelf life significantly. When you buy a premium product like NICK'S you want to ensure it stays in perfect condition down to the very last spoonful. Refrigeration also helps keep the oil from separating too much after you have given it that initial stir. Treating your food with care reflects the respect you have for your own body and your high nutritional standards.
