Most people get this wrong and toss out the can. The right way to read ‘Best By’ or ‘Best Before’ dates.

In the world of packaged foods, “Best By” and “Best Before” dates are ubiquitous, yet often misunderstood. Contrary to popular belief, these dates do not signal when food becomes unsafe to eat, but rather when it is likely to be at its peak flavor and texture. Unfortunately, this confusion leads many people to discard perfectly good food, contributing to the growing problem of food waste. Learning how to properly interpret these labels—especially when it comes to canned goods—can help consumers make smarter, more sustainable choices.
Understanding the Purpose of ‘Best By’ Dates
‘Best By’ dates are set by manufacturers to indicate the period during which the food is expected to maintain its best flavor, color, and nutritional quality. These dates are based on factors like the type of food, packaging materials, and expected storage conditions. In most cases (with the exception of infant formula), these dates are not federally regulated, meaning they serve as guidance—not a safety deadline.
