The primary purpose of food labeling is to provide consumers with nutritional information about the food they are purchasing.

Food labeling can help to minimize food waste by providing consumers with information about the food's shelf life. This information can help consumers to avoid purchasing food that is likely to go to waste.

A "best before" date indicates the date after which the food may start to lose its quality, but it is still safe to eat. An "expiration date" indicates the date after which the food is no longer safe to eat.

The "use by" date on food labels indicates the date after which the food is no longer safe to eat.

Consumers should be aware of common food labeling terms such as "organic", "natural", and "gluten-free" in order to make informed choices about the food they purchase.

Consumers can use food labeling to reduce food waste by checking the "best before" and "expiration" dates before purchasing food, planning meals and shopping lists based on the food they already have on hand, storing food properly to extend its shelf life, and composting food scraps and using them as fertilizer.
