About
Bison Meat
Bison
meat provides a healthy alternative to other meat sources. Rich in vitamins and
minerals, while low in fat, cholesterol and calories, the nutritional content
of bison is impressive.
Protein
Protein
is used in the human body to build and repair tissues, produce enzymes and some
hormones, and maintain cell membranes and components of the immune system.
Bison meat is a rich source of protein as each serving has about 22 grams of
protein. Bison cuts are complete proteins containing all the essential amino
acids in appropriate amounts.
Low
in Fat
Not
only is bison meat a rich source of protein, it also is very low in fat,
containing roughly 2 percent fat per serving, and only 66 mg of cholesterol per
serving. Current recommendations are that Americans should consume less than 30
percent of their calories from fat and less than 300 mg of cholesterol daily.
Bison meat can be labeled as low-fat according to labeling regulations. The
types of fat present in bison are worth mentioning. Monounsaturated fats
account for over 46 percent of total fats present in bison, while 43 percent of
the fat is saturated, and the remaining 11 percent is polyunsaturated. American
Heart Association dietary guidelines call for obtaining all three types of fat
as part of a healthy diet, with up to 15 percent of calories being from
monounsaturated, up to 10 percent of calories from polyunsaturated, and 8 to 10
percent of calories from saturated. Monounsaturated fats often are touted as
the "healthy fat," because eating them does not raise cholesterol levels.
Omega-3
and Omega-6
Bison
meat contains linoleic and linolenic fatty acids, which also are known as
omega-3 and omega-6 fatty acids, respectively. These omega fatty acids are
believed to be useful in many functions of the human body including assisting
in formation of cell membranes, aiding in the production of hormone-like
compounds, and participating in immune and visual processes. These two omega
fatty acids are called "essential," meaning the substance is necessary for us
to eat and cannot be made in our bodies.
Low
in Calories
The
food energy or caloric content of bison cuts is low, particularly for a meat.
The average caloric content of a serving of bison is about 140 calories, which
is about 7 percent of calories, based on a 2,000 calorie diet.
Vitamins
and Minerals
Bison
meat is a rich or good source of vitamins and minerals (Figure 1). When a food
contains 20 percent or more of the Daily Value or Reference Daily Intake of a
nutrient per serving, the terms 'major source of,' 'rich in,' or 'high' can be
used to describe the content of this nutrient in the food or food product. The
term 'good source,' 'source of,' or 'important source of' indicates that a food
contains from 10 to 19 percent of the nutrient per serving.
Bison
meat contains many vitamins but is highest in vitamin B12, vitamin B6, and
niacin content. Bison meat contains enough vitamin B12 to be considered a major
source of the vitamin, since one serving of raw bison meat contains 43 percent
of the Daily Value. Vitamin B12 is involved in folate metabolism and also is
used in maintenance of myelin sheaths which insulate nerve fibers. A serving
contains 12 percent of the Daily Value for vitamin B6, which is used in protein
metabolism and formation of several neurotransmitters. It is also a good source
of niacin, providing 10 percent of the Daily Value per serving. Niacin plays a
role in energy metabolism as well as fat synthesis and fat breakdown. Vitamins
present in a serving of bison meat to a lesser extent are riboflavin at 6
percent of the Daily Value, thiamin at 3 percent of the Daily Value, and
vitamins A and E at insufficient levels to be of nutritional importance. It
does not contain detectable amounts of vitamin C and folic acid.
Bison
meat contains many minerals but is highest in selenium, zinc, phosphorus, iron,
copper and magnesium content. Bison meat is high in selenium, containing about
47 percent of the Daily Value per serving. Selenium functions as an
antioxidant, helping to prevent free radical damage. Bison meat is a major
source of zinc, containing about 25 percent of the Daily Value per serving.
Zinc is used in wound healing, protein metabolism and the storage and release
of insulin. A serving of bison meat contains 20 percent of the Daily Value for
phosphorus. Phosphorus functions in energy metabolism and nucleic acid
synthesis, and is a component of bone and of some buffers.
A
serving of bison meat is a good source of iron, containing 16 percent of the
Daily Value. Iron helps transport oxygen to cells and returns carbon dioxide
from the cells. Iron is also important for immune function. Minerals present in
a serving of bison meat to a lesser extent are potassium at 9 percent of the
Daily Value, copper at 7 percent of the Daily Value, magnesium at 6 percent of
the Daily Value, and calcium and manganese at levels insufficient to be of
nutritional importance.
Bison
meat contains 45 mg of sodium per serving, and is low in sodium, containing
less than 140 mg of sodium per serving. Adults and children should consume less
than 2,400 mg of sodium daily. Most Americans consume more sodium than
recommended. High intakes of sodium have been associated with increased
prevalence of hypertension.
The
nutrient content data presented so far in this paper are based on raw meats.
Consumers and food service staff cook meat differently and, occasionally,
improperly. Cooking can affect the nutrient composition of meat. The mineral
content of the ribeye cut of bison has been reported to increase following
broiling because of the loss of moisture in the meat during cooking. However,
59 percent of the thiamin, 68 percent of the vitamin B6, 67 percent of the
vitamin B12 and 76 percent of the vitamin E were retained when bison patties
were either broiled or grilled. Therefore, one might expect retentions of about
two-thirds for the B-vitamins and about three-quarters for the fat-soluble
vitamins.

BISON
IS ALSO HEALTHY FOR YOUR HEART
The
American Heart Association has recently recommended bison meat as
a lean meat choice for a heart-healthy diet.
It is a nutrient-dense food because of the proportion of protein, fat,
minerals, and fatty acids to its caloric value.
This means that nutritionally you are getting more protein and nutrients
with fewer calories and less fat. In
other words, bison is a meat that tends to satisfy you more while you eat less.

to these other meats. Bison are
bullish on nutrition!
