Humans aren't the only mammals to get cravings for potato chips. A recent study shows that bears (or at least the bears of Wisconsin) get hankerings for popcorn, pretzels, cookies, and other junk foods, just like we do—if not even more often.
Researchers with the University of Wisconsin, Madison analyzed the diets of more than 100 bears who had been killed by hunters in the northwest region of the state from 2011 to 2013 by measuring chemicals in the bears' hair, blood, and bones.

The chemicals told the researchers how much meat, plants, and bait—food hunters leave out to lure bears during hunting seasons, which is usually junk food—that the bears had eaten. And they soon found that about 40 percent of the bears' diet came from bait, not just in the years they had been hunted but over their lives, telling the researchers the bears went in search of junk food even when it wasn't made readily available to them. In other words, they say, these bears got cravings for chips, too.
