For researchers at the College of Connecticut, there’s no question about it: Junk food is addictive. Most addictive are heavily processed snacks that have high levels of sugar and fat, like Oreo cookies. In fact, a recent study indicates that Oreo cookies are just as addictive as cocaine or morphine. This is a startling discovery for parents and children alike, as Oreos are one of America’s favorite sandwich cookies. Nevertheless, the discovery underscores and important fact: The American diet is rich in high-fat and high-sugar snacks that wreak havoc on the teeth, gums, and total body health.
