Slim Jim is the ultimate handheld snack and because it’s made with meat, it's meant to keep you full while you're on the move, whether on a long car ride or a day on the job.

These popular snacks are considered processed meat, so they're made with lower-quality beef than what you'd bring home from the grocery store.

Processed meats usually involve one of three meat types: Canner, utility, and cutter. All three fall in the lowest-grade category.

Utility meat is usually used for frozen or canned meals, while some sources assert that cutter and canner meats are used in pet food.

These cuts usually come from older cows with less desirable meat. Slim Jims are also supplemented with a little pork and mechanically separated chicken.

Beyond that, the Slim Jim meat also contains other proteins and amino acids like wheat, corn proteins, and soy proteins. The result is a salty snack that is hard to resist.
