Understanding this matters because food waste has become a major issue. In the United States, an estimated 30–40% of food goes uneaten every year, often ending up in landfills. Much of this waste comes from confusion over date labels, leading people to discard items that are still usable. This isn’t just tough on household budgets—it also impacts the environment. Producing food requires water, energy, and transportation, all of which go to waste when food is thrown away unnecessarily. Thankfully, there are simple ways to cut down on this waste. Paying attention to proper storage, using airtight containers for dry goods, keeping refrigerators at safe temperatures, and freezing items we won’t use soon can all make a noticeable difference.

Of course, printed dates aren’t the only way to judge freshness. Our senses—sight, smell, and texture—can tell us a great deal. If something smells off, looks unusual, or feels strange, it’s best to discard it. But if food appears normal and has been stored well, it often remains safe past the date on the package. Canned items, dry goods, frozen foods, and even eggs can last much longer than most people expect. By learning how to evaluate food thoughtfully and storing ingredients correctly, we can waste less, save more, and make the most of what we buy. The next time you see an expiration date and feel tempted to toss something immediately, pause for a moment. A quick look, a careful sniff, and a bit of common sense may show that it’s still perfectly good—helping your wallet, your meals, and the planet along the way.
