Animals at the zoo gain weight from eating processed foods

Heavily processed foods have been blamed for the ever-expanding waistlines of the human population, as well as a number of health problems. But humans aren't the only ones affected by how our food is made. According to this article, animals at the zoo in Seoul, Korea, have become so overweight from their diet of processed foods that they are going on a strict diet.

I think this is very unfortunate -- it's one thing for humans to cause their own health problems by giving into their cravings, but it's another when harmless animals are being fed junk food when they're helpless to do anything about it -- especially because it probably boils down to the zookeepers being too frugal to purchase real foods for the animals.
