1 . Scientists at the University of Minnesota report Thursday in the journal Science that about a third of all food grown around the world never gets eaten. In terms of calories per person, cutting food waste is more of an immediate opportunity to feed more people than increasing crop yields around the world.

“But not all these calories are equal, when you look at how they hurt the global food supply,” says Paul West, who led the study. “Throwing away a pound of boneless beef effectively wastes 24 times more calories than discarding a pound of wheat. If you throw out some cabbage at a fancy restaurant in upstate New York, it doesn’t have much impact on the world’s food system. But throwing out a small steak has a huge impact—maybe more than all the cabbage in the restaurant put together. Wasting other animal products, such as chicken, eggs and dairy, has less effect on the global food supply than beef, but still more than vegetables and grains.

The US, China and India together throw out enough food each year to feed more than 400 million people, the team found. And the biggest global contributor to that loss is the US. Each day the average Americans waste up to about 1,200 calories per person. They throw out 290 effective calories from beef. They also waste about 550 calories from chicken and pork.

On the other side, India wastes the least amount of food and meat of the three countries. Each Indian, on average, effectively throws out about 44 calories a day, mostly rice and wheat.

China falls between the US and India. Each Chinese person wastes about 280 calories of wheat and rice every day. But the Chinese also love pork and each person effectively tosses 200 calories from pork each day. “The food service industry in China has really high amounts of waste,” West says. “It’s a cultural standard for them to order seven to nine dishes in restaurants to honor the guests. All that food doesn’t get eaten.”
