Are Left-Over Foods Good for Human? Or Otherwise? A survey has been gone to public on the left-over foods discarded by the fast foods and restaurants. Tons of those foods are being thrown by those foods sellers. Those uneaten or excess foods by the customers couldn't be thrown away or be fed to the animals for they could be processed in any way. Couldn't they? At home, sometimes we have some extra cooked rice and we fried them and reeat them. Excess fried fishes are processed in a sweet-sour dish with a little soup. They are still good and taste better as long as they are prepared deliciously with the tasty, seasonings or ingredients. In your case, what do you do with your left-over foods? Do you feed them to the dogs, cats, or hogs? Or do you just throw them away?
