Health Benefits of Bison
Bison is one of the best red meat options for fitness-focused eating. At 146 calories per 100g with 20.2g of protein, it delivers a high protein density with a lean fat profile. The 7.2g of fat per 100g is considerably lower than conventional ground beef, making it easier to hit protein targets while staying within a calorie budget.
Zinc (4.6mg per 100g) is critical for testosterone production, immune health, and protein synthesis. Bison also provides selenium (20mcg per 100g), which supports thyroid function and acts as an antioxidant to protect cells from oxidative damage after training.
The vitamin B12 content (1.9mcg per 100g) and niacin (5.3mg per 100g) support energy metabolism, making bison a solid choice for pre- or post-workout meals. With only 0.1g of carbs per 100g, it is ideal for low-carb and keto diets.
Bison is grass-fed by nature since it is a wild game animal, meaning the fat quality tends to be favorable compared to conventionally raised beef. For those who want the taste of red meat without compromising their body composition goals, bison is a practical upgrade.
Dietary Considerations
Bison is naturally gluten-free, low-carb, and keto-compatible with only 0.1g of carbs per 100g. It is not suitable for vegans or vegetarians. Bison is paleo and carnivore diet friendly. The lower saturated fat (2.9g per 100g) compared to conventional beef makes it a somewhat better choice for those monitoring saturated fat intake. It fits well into high-protein, calorie-controlled eating plans for body recomposition. Cholesterol is present at 55mg per 100g, which is relatively modest for a red meat. Bison is widely available as ground meat, steaks, and patties.
