I would use this graph only as a rough estimate. It’s quite dated. That being said I will tell you that you can hardly go wrong with nature. Bison are not bred & raised like cattle. We do not use questionable drugs, chemicals or growth hormones.  NBA (National Bison Assoc.) opposes the use of these substances in the production of bison for meat. Just look at a cut of bison meat, visually has less fat than beef. It has a beautiful deep red coloring. Bison are native to North America and have not been imported or bred for faster growth for production money, like most commercial meat sources in the U.S. have. If you’re eating bison, you are supporting America’s only native cattle, and we thank you!

How Healthy Is Bison Meat?

High Protein and Low Fat (bison meat nutritional value)

A 3-ounce serving of roasted bison meat contains 122 calories, 24.2 grams of protein and 2.1 grams of fat, including just 0.8 gram of saturated fat. This is 48 percent of the daily value for protein, 3 percent of the DV for fat and 4 percent of the DV for saturated fat for those who follow a 2,000-calorie diet. This is less fat than even grass-fed beef, according to a 2012 article published in “Mother Earth News.”

5 Reasons to Eat Bison: The new healthy red meat.

By Katalin Rodriguez Ogren, February 6, 2012

1. It is taster than beef and richer in flavor.
2. It is simply healthier than regular cow beef.   It is lower in saturated fat than regular cow beef.
3. Bison is a great source of nutrients, it has the basics: zinc, niacin, iron, vitamin B6, and selenium.  A quick review of some important things these nutrients do: Selenium – helps prevent cellular damage from free radical.
   Zinc- does a lot- helps immune system, hair, and skin health and overall cell function
   Niacin helps convert food into energy for the body – all at the cellular level
   Iron- carries oxygen through the body
   B6- tons of value of for physical and even mental health.
4. 4.  Bison cattle are not handled like cows.  They are mostly living in a freer environment compared to cow/cattle.  Although there are many cattle farms that treat the cows humanely, bison seem to be cared for like the elite class of the farm.
5. 5.  Bison is one of the leanest meats and still has a lot of protein.  But it is the amount of protein you get in bison meat, without the saturated fat that makes this a great alternative to regular beef.
