Nuts: Refrigerating nuts can extend their shelf life by preventing the oils they contain from going rancid. This keeps them fresher and tastier for longer.
Whole Grains: Like nuts, whole grains contain oils that can spoil over time. Storing them in the refrigerator can help maintain their freshness and nutritional quality.
Natural Peanut Butter: Without preservatives, natural peanut butter can separate and spoil more quickly at room temperature.
Hard Cheeses: While not all cheeses need to be refrigerated for short-term storage, hard cheeses last longer and maintain quality better when kept cool.
Maple Syrup: Pure maple syrup can mold if stored at room temperature after opening. Refrigeration prevents spoilage and maintains quality.
