Calories in Bison, ground

What makes bison so powerful?

The American bison nearly went extinct in the late 19th century, dropping from tens of millions to fewer than a thousand individuals. This catastrophic population bottleneck means almost all modern bison carry genetic traces of crossbreeding with cattle, intentionally done by early ranchers to save the species. Despite this bovine ancestry, bison meat retains a distinct nutritional and chemical profile. Because bison evolved to forage in harsh North American climates, they store less intramuscular fat—known as marbling—than domestic cattle. This biological difference results in a meat matrix that is structurally leaner and naturally richer in heme iron, the highly bioavailable form of iron that gives the meat its deep, dark red color. The lower fat content also means the meat lacks the heavy lipid coating on the palate that beef often leaves behind, allowing the sweet, slightly mineral notes of the myoglobin to come forward more prominently. Today, conservation efforts have restored their numbers to over half a million, making this once-endangered protein a viable, sustainable option for modern diets.
