Americans throw away spoiled fruits and vegetables two times a week on average, wasting approximately 15-20% of fresh fruits and vegetables every year, according to recent studies by the Natural Resources Defense Council. In fact, a study by the University of Arizona and United State Department of Agriculture (USDA) noted that 40-50% of all harvestable food in the United States is discarded, which amounts to approximately 34 million tons of food annually. What may be most troubling about this trend is that it doesn’t seem to be slowing down. The Natural Resource Defense Council reports that food waste has increased by 50% since the 1970s, costing the U.S. economy more than a $1 billion each year.
A recent study by the USDA Economic Research Service examined fresh, frozen and canned varieties of various fruits and vegetables to determine the differences between food purchased and food consumed. The study measured food waste associated with cooking, as well as uneaten food thrown away. Canned varieties had the lowest consumer-level loss for many of the products examined. When testing sweet corn, only 7% of canned corn was wasted, compared to fresh, which had 32% consumer-level loss, and frozen, with a 36% consumer-level loss. Similarly, canned peaches had an 8% consumer-level loss, versus fresh, at 42%, and frozen, at 35%. Canned fruits and vegetables are picked and packed at the peak of ripeness. The can’s optimized vault-system seals in the freshness and nutrition of products until consumers are ready for consumption. Those products remain safe and delicious until they’re taken off the shelf, which results in less waste. What’s more, canned fruits and vegetables are often full of more nutrients than their counterparts because the nutrition of the freshly picked products is locked in. The Journal of the Science of Food and Agriculture confirmed that canned peaches pack as many nutrients as fresh—and retain nutrients much longer.
