Protein sources vary widely, so storage depends on the specific item. Meats, poultry, and fish should always be refrigerated promptly and used within a few days, or frozen for longer storage. Eggs should be refrigerated in their original carton. Dry beans, lentils, and nuts should be stored in airtight containers in a cool, dry place. Protein powders should be stored in a cool, dark, and dry place, tightly sealed to prevent moisture absorption.
