About 200 million pounds of turkey are thrown out around Thanksgiving. Here's how to reduce food waste.

Roughly a third of all food is lost or wasted from the U.S. food supply each year and, with its big holiday meal as the centerpiece, Thanksgiving can be one of the most wasteful days of the year, according to experts.

With the price of sweet potatoes, cranberries, potatoes and wine up compared with last year, shoppers may want to carefully consider how much to make for the holiday. Minimizing food waste also keeps food out of landfills, cutting down on emissions of methane — a powerful greenhouse gas.

"The food on your table is the result of many resources," said Dr. Jean Buzby, liaison for food loss and waste at the United States Department of Agriculture. "Fresh water, energy, land and labor are used to create, process, transport, store, market and prepare that food. Do what you can to keep your food out of landfills so that all those resources are not wasted."
