Walk down a grocery store aisle, and you will find packages promising everything from natural ingredients to certified organic products. Both labels can make food sound healthier, cleaner, or closer to the way nature intended, but they do not mean the same thing. One generally describes certain characteristics of a food or how it has been processed, while the other follows specific federal production standards. Understanding that distinction can help you decide when a higher price is justified and when a less expensive alternative may offer what you need. Before paying extra for a product with reassuring words on the package, it helps to know what those words actually mean.
