First In, First Out: A Sustainable System for Rotating Your Food Storage

First In, First Out (FIFO) is the same principle grocery stores use to keep shelves fresh, applied to your own pantry. New purchases go to the back of the shelf; older stock moves to the front, where it gets used first in everyday cooking.
The practical payoff is that your emergency stockpile stops being a separate, static thing you're afraid to touch, and becomes part of how you actually eat. That solves two problems at once: less waste, and a stockpile that's genuinely useful because you know how to cook with what's in it.
Label everything with a purchase or best-by date using a marker or a simple sticker system, and organize by category rather than by brand: grains together, canned proteins together, and so on, so gaps in your rotation are visible at a glance.
Once a season, do a full pantry walk-through: check dates, note what's running low, and restock deliberately rather than in a panic-buy. A sustainable system is a boring one that you actually keep up with.
