You pay a lot of money for that artisan loaf of bread, then don’t eat it all before it gets stale. You have a recipe that calls for egg whites (or yolks) but not the rest of the egg. The rotisserie chicken is pretty much stripped of the best meat. But don’t throw them away! Some estimates say that we waste as much as 40% of our groceries because we buy them but don’t eat them. In 2010, Americans wasted nearly 24 billion tons of food – enough to fill the Empire State Building 91 times. OK, enough of the shocking statistics. Ask yourself, though: How much of the food I buy ends up in the trash or compost heap? Maybe you’re just not being smart about using things that seem useless. We have come up with a list of five foods you should never throw away until you get every last bit of use, and nutrition, out of them. Read all about it on our sister site, Living on the Cheap.
