Nutrients that Work as Hard as You Do
IRON
is a mineral that plays a vital role in many biological functions. It
helps carry oxygen to body cells and tissues, assists in making new red blood
cells, aids brain development and supports the immune system --- all to keep you
healthy. Research has shown 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 United States. Beef is the number three source of iron in the American
diet following iron-enriched breads and cereals. However, the iron in red meat
is more completely absorbed by the body than the iron found in bread, cereal,
and other plant products. Two factors can increase the absorption of iron from
plant foods --- meat and vitamin C. Meat consumption at a meal has been shown to
increase the absorption of plant iron two- to four-fold. This enhancing effect
is known as the "meat factor." Eat a variety of foods and pair
iron-enhancing foods with iron-rich foods to increase iron absorption. Try
sirloin strips with a spinach salad for a delicious high-iron meal.
PROTEIN
plays many roles that help keep you
energized and support your body 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 you from disease. •
Proteins can even serve as an energy source. You need to eat enough protein
daily to support growth and maintenance of tissues, and to replace proteins that
are broken down by the body. All foods contain some protein,
but the amount and quality of the protein vary greatly. Meat, fish, poultry,
legumes, eggs, nuts, soy and dairy products are considered high-protein foods.
Proteins from animal sources, such as beef, are high-quality or complete
proteins. Vegetables and grains also contain protein, but in lesser amounts. One
3-ounce serving of beef provides 50% of the protein recommended daily. All
this high-quality protein comes in the same delicious package with zinc, iron
and B-vitamins! That's a great fuel to help power you through the day.
B-VITAMINS
work to promote growth and maintain health. You need essential
B-vitamins to "unleash" the energy in food. Calorie for calorie, beef
is one of the best sources of many essential B-vitamins. A balanced diet that
includes beef can help give you the energy you need to tackle your busy days. WHEN IT COMES TO NUTRITION, BEEF HAS A COMPETITIVE ADVANTAGE.
FAT
is an essential nutrient. It provides for the
absorption of fat-soluble vitamins and the formation of hormones, and it can be
used as an energy source. But remember, don't overdo it. To choose a diet
moderate in fat, select lean cuts of meat, skinless poultry and low fat dairy
products. Balance low fat and high fat options over time. Half of the fatty acids in beef are monounsaturated, the same type of fatty acids found in olive oil and championed for their heart-healthy properties. In addition, approximately one-third of the saturated fat in beef is stearic acid. Studies have shown that stearic acid does not raise blood cholesterol levels like other saturated fatty acids do. Types of Fatty Acids in Various Foods (PDF) Lean beef fits easily into low fat
meal plans designed to decrease blood cholesterol levels. Research shows that
Americans can eat six ounces of lean red meat five or more days a week as part
of a cholesterol-lowering diet. Further, both red and white meat produce the
same favorable changes in blood cholesterol levels. In other words,
lean
beef is just as effective as skinless chicken when it comes to lowering blood
cholesterol levels. Home / About Us / Contact Info / Nutrition / Food Safety / Teacher Resources / Recipes / Links |
