A 3.5-ounce serving of grass-fed bison meat has 146 calories, 7.2 grams of total fat, and 55 mg of cholesterol, according to the USDA. While it has the same amount of calories as turkey and chicken, bison contains less fat and cholesterol, as well as significantly fewer calories and fat than 84 percent lean pig. Grass-fed beef has less fat and more nutritious things like vitamins and minerals than grain-fed beef. Bison has more protein than most other meats, with about eight ounces containing about 50 grams. That's more than double what you'll get from three ounces of 95 percent lean ground beef and almost twice that of lamb. Fish is very high in protein with 87 percent dry matter; pork has about 53 percent; and chicken has about 42 percent. Bison is also low in saturated fat and has less cholesterol than most other meats. A 3.5-ounce serving contains 7.2 grams of total fat and 55 mg of cholesterol. That's less than half the amount of fat and less than one third the amount of cholesterol of an equal weight serving of ground beef. The USDA recommends that men eat no more than 300 milligrams of cholesterol per day and women no more than 200 milligrams. Bison contains only 55 milligrams of cholesterol per 3.5-ounce serving. It also has less saturated fat than most other meats.
