Which factor contributes the greatest to food waste in the United States?

The factor that contributes the greatest to food waste in the United States is primarily related to the confusion surrounding food labeling date phrases. Misinterpretation of labels such as "sell by," "best by," and "use by" leads consumers to discard food that is still safe and edible. This confusion is significant because it directly affects consumer behavior, driving them to throw away items prematurely instead of utilizing them.

Understanding food labels is crucial in managing food waste effectively. When consumers misinterpret these dates, they often assume that food is no longer good even when it is perfectly fine to eat. This unnecessary discard contributes to a substantial amount of waste at the consumer level, making it a critical factor in the overall problem of food waste in the country. Addressing educational initiatives that clarify food labeling can help minimize this confusion and ultimately reduce waste.
