By Lisa Rapaport (Reuters Health) – Americans throw out more than one third of the food produced in the U.S. each year – enough to fill 320,000 jumbo jets – with most of it going straight into landfills. “Becoming more observant of food that finds itself in the landfill rather than in a stomach can help shift our buying habits,” Brown added by email. “This can come in the form of ordering less food when dining out, freezing bananas before they over ripen, or even making a meal plan for the week to help cut costs and waste.” Waste can occur anywhere in the U.S. food chain, from farms, processors, distributors, wholesalers, retailers, restaurants and home kitchens, Brown and co-author Chris Vogliano note in the Journal of the Academy of Nutrition and Dietetics.
