Q: Is bison a healthier choice than beef?

A: Bison is a trendy option, both for its perceived heath benefits and, for some people, the sweet, rich flavor. The meat is promoted as containing less fat than beef, but that depends upon cut, grade and trimming. Bison is also more expensive than beef, so it’s worth a closer look at the health claims.

Comparing similar cuts, bison comes out slightly leaner. According to USDA nutritional analysis, a three-ounce cooked portion (the size of a deck of cards) of bison ribeye contains 150 calories and 2 grams of saturated fat. Beef ribeye graded “choice” (with more marbling throughout the meat) contains 177 calories and 3 grams of saturated fat. But a leaner option, beef ribeye graded “select,” is similar to bison, in calories and saturated fat. Lean cuts like this from either source are good choices to help you limit saturated fat for heart health. Bison meat tends to have less fat marbled through the meat, so for higher fat cuts you may be able to trim off some fat.

For bison burgers, USDA figures for a three-ounce portion range from approximately 150 to 200 calories, depending on the amount of fat. Ground beef burgers are often higher in fat, but with comparable percent fat choices, calories and fat are similar. Some consider bison a healthier choice because it is grass-fed and raised without hormones, though some are now fed grain for the final few months. The health impact of these differences isn’t yet known, though it is clear that the increase in omega-3 fat of grass-fed bison or cows is small.

We don’t have research from population studies looking at whether long-term consumption of bison is any different in risk of colorectal cancer than other red meats. Based on its nutritional composition, it would make sense to keep its use within the recommended limit for total red meat of 18 ounces per week.


The American Institute for Cancer Research (AICR) is the cancer charity that fosters research on the relationship of nutrition, physical activity and weight management to cancer risk, interprets the scientific literature and educates the public about the results. It has contributed over $105 million for innovative research conducted at universities, hospitals and research centers across the country. AICR has published two landmark reports that interpret the accumulated research in the field, and is committed to a process of continuous review. AICR also provides a wide range of educational programs to help millions of Americans learn to make dietary changes for lower cancer risk. AICR is a member of the World Cancer Research Fund International (WCRF).
