KYLE, S.D. (AP) – A Pine Ridge Indian Reservation company that makes the buffalo-meat-and-cranberry Tanka Bar has rebranded its product line.

Native American Natural Foods President Mark Tilsen that included coming up with shrink-wrapped packaging to better protect the snacks.

They’re popular among athletes, diabetics and people looking for a quick, low-carbohydrate snack.

Bison meat is high in protein and low in cholesterol, while the cranberries add antioxidants and flavor.

Tilsen says the new line is focused on being more of a snack people can grab on the go, which allows the company to expand where the bars are sold.

He says Tanka Bars are now available on 375 of the more than 550 American Indian reservations in the U.S.
