If all the food that’s thrown away in three American cities could be saved, it would provide 68 million meals for people who don’t have enough to eat, according to a recent study.

The researchers found that, in the cities they surveyed（调查）, more than a kilogram of edible food per person is wasted each week. Edible food is food you can eat. It doesn’t include things like apple cores（果核）, egg shells, or bones from meat. Fruits and vegetables were the most common edible foods found in the dustbin, followed by food leftover from meals. Eggs, bread and milk were also commonly thrown out.

The people taking part in the survey gave several reasons for throwing edible food away. Most said the food went off. Some said they weren’t interested in eating leftovers. A few said the food had passed the “Best Before” date printed on the label（标签）. When food is wasted—by families, restaurants or grocery stores—we are also wasting all of the resources that go into producing that food. That means we are wasting water, land, energy and labour, as well as the fuel needed to transport food.

A lot of food is wasted before it even reaches the grocery store（食品杂货商）. Some food is damaged while it is being transported from the farm to the stores. Fruits and vegetables that don’t look attractive enough don’t even get put onto the shelves because most people won’t buy them. Grocery stores, restaurants and hospitals also waste a large amount of food. The researchers suggest that grocery stores should donate any food that is still okay to eat to homeless shelters, instead of throwing it away. Prepared meals from hospitals or restaurants could also be donated to shelters.
