What does protein
do for me?
Protein plays many roles
that help keep you energized and support your body's functions.
Proteins are part of all
your body's tissues, including muscles, organs and bones.
Proteins make up the
hormones and enzymes that regulate body processes.
Proteins work with the
immune system to protect against disease.
Proteins can even serve as
an energy source.
Protein may help prevent the muscle-wasting disease, sarcopenia.
Protein improves the
bodys ability to build muscle mass.
Protein may help the
body maintain a healthy weight by increasing metabolism during
sleep.
Protein helps increase satiety, curbing hunger and making you
feel full.

How
does protein benefit my body throughout life?
Protein provides unique body benefits
throughout each stage of life:
Protein is an essential
nutrient that plays many roles that help you feel energized and
support your bodys functions at any age.
Numerous studies show that
higher protein diets help people feel more satisfied, which can help
people lose or maintain weight at any age.
Research shows increasing
the proportion of protein to carbohydrates in the diets of adult
women may have positive effects on body composition, blood lipids
and satiety during weight loss.
Research indicates that
middle-aged people who eat more protein-rich foods, such as beef,
have fewer hip fractures resulting from osteoporosis.
Consuming lean protein can
improve your ability to increase or maintain muscle mass, and as a
result, may delay the onset of sarcopenia or loss of muscle, in
older adults.

How
does protein fuel strength?
Research shows protein intake builds muscle strength and metabolism and,
a protein-rich diet can help maintain muscle mass while burning fat.
Studies also show exercise is more effective when coupled with a
moderately high-protein diet. In addition, scientific evidence suggests
that the benefits of muscle mass development and metabolism go beyond
body strength and may play a critical role in the prevention of many
chronic diseases, such as type-2 diabetes and osteoporosis. Back to Top

Shouldnt I be avoiding saturated fat?
The government tells us to limit saturated fat, ideally to no more than
20 grams per day for an average 2,000-calorie diet. If you eat fewer
calories, you need to keep your saturated fat intake under 10% of
calories. These cuts on average have just 1.9 grams of total saturated
fat. Thats well within this limit, and with that, you get 38% of your
daily value for zinc, 14% of your daily value for iron and 37% of your
daily value for vitamin B-12. Beef is a great-tasting, nutrient-rich
protein.

What nutritional
benefits does beef offer?
Beef is a power pack of nutrients that benefits people of all ages in
maintaining both day-to-day and long-term health. A 3 oz. serving of
beef is an excellent source of protein and a good source of iron, zinc,
niacin, vitamin B6 and vitamin B12, while contributing less than 10% of
the calories to a 2,000-calorie diet.
Beef is the #1 food source
of protein, zinc and vitamin
B12, according to a study published in the Journal of
the American Dietetic Association.
Beef supplies high-quality
protein, complete with all nine
essential amino acids.
Beef is one of the most
important dietary sources of iron.
To obtain the same amount of iron found in a 3 oz.
serving of beef, you'd have to eat at least 3 cups of
raw spinach.
A 3 oz. serving of beef
provides 39% of the Daily
Value for zinc. You would need to eat more than eleven
3 oz. servings of tuna to get the same amount of zinc in
one 3 oz. serving of beef.
Beef contains significant
amounts of the B-complex
vitamins riboflavin, niacin, thiamin, B6 and B12.

I know that iron
is necessary for healthy blood, but what else is it good for?
In addition to helping make new red blood cells, which help carry oxygen
to body cells and tissues, iron aids in brain development and supports
the immune system. Research has shown that even mild, short-term iron
deficiency can impair your ability to function at peak productivity. And
yet, iron deficiency is the most common nutritional deficiency in the
U.S.

Why is zinc
important to my health and nutrition?
Zinc may not be a nutrient you think a lot about, but your body needs it
for essential functions. Zinc plays a vital role in growth and
development, maintaining the body's immune system, wound healing, taste
perception and appetite control.

Are there other
significant vitamins & minerals in beef I should know about?
Selenium is an antioxidant
that works with vitamin E to
help prevent damage to your body's cells. Recent studies
have found that adequate intake of selenium may reduce
the risk of heart disease and certain types of cancers and
improve the body's ability to fight infections. A 3 oz.
serving of beef provides 26% of the selenium you need
daily.
Choline, another essential
nutrient, plays a vital role in
cognition and long- and short-term memory functions.

Tell me more about the
B-complex vitamins in beef.
Calorie-for-calorie, beef is
one of the best protein sources
of essential B-complex vitamins, including riboflavin,
niacin, B6 and B12.
Riboflavin, niacin and
thiamin are three key vitamins in
beef that help keep you going by unleashing energy from
the protein, carbohydrates and fats that you eat.
Riboflavin also helps
promote healthy skin, eyes and
clear vision. To get the same amount of riboflavin found in
a 3 oz. serving of beef, you'd need to consume more
than two 3 oz. chicken breasts.
Thiamin also helps promote
normal appetite and
contributes to normal nervous system function.
Vitamin B12, found only in
animal food products, helps
produce red blood cells. A 3 oz. serving of beef
provides 37% of the Daily Value.
Vitamin B6, along with B12,
may play a role in preventing stroke and heart disease. A 3 oz.
serving of beef provides 15% of the Daily Value.

I know that beef
provides many nutrients that are good for me, but what about the fat
content?
The beef industry has responded to consumer concerns about fat and is
now producing a product that is leaner and contains less visible fat
than it did just 10 years ago.
Half the fatty acids in beef
are monounsaturated, the same
heart-healthy kind found in olive oil.
32% of the saturated fat in
beef is stearic acid. Studies
have shown that stearic acid has a neutral effect on
blood cholesterol levels.
There are at least 29 cuts
of beef classified as lean or
extra lean according to USDA labeling guidelines. On
average, these cuts have 6.2 grams of total fat and 2.3
grams of saturated fatty acids per 3-ounce serving. They
are: eye round, top round, round tip, top sirloin, bottom
round, top loin, tenderloin and flank steak.
Beef contains conjugated
linoleic acid, a fatty acid that
recently has sparked a lot of interest in the scientific
community, due to its numerous potential health benefits.

Why is conjugated
linoleic acid potentially important?
Conjugated linoleic acid (CLA) is a fatty acid found naturally in beef
and dairy products. Animal studies have shown it to have many benefits.
Further trials hope to confirm similar benefits in humans.
CLA has been found to be
more powerful than any other
fatty acid in preventing the formation and slowing the
growth of cancerous tumors.
CLA can affect body
composition by decreasing body fat
and increasing lean muscle mass.
CLA may help normalize blood
glucose levels and
prevent diabetes.
CLA may contribute to heart
health by helping to lower
serum cholesterol and triglyceride levels.
CLA has been shown to
stimulate the immune system
and to have positive effects on bone health.
