Sirloin is a versatile cut of beef. It is much more affordable than the all-popular filet mignon or the high-fat ribeye. If you know your way around the kitchen, ground sirloin can be part of a nutrient-packed gourmet meal. While red meat generally has an unhealthy reputation, it can be part of a balanced and healthy diet. It provides an abundance of vitamins and minerals that are necessary for muscle health and red blood cell production.
High in Protein
The recommended daily allowance of protein for men is 56 grams per day, while women need 46 grams. For each 3-ounce serving of ground sirloin, you get a whopping 25 grams of protein. This is slightly more than the same serving size of a chicken breast, coming in at about 24 grams of protein per serving. Protein is necessary for every cell, tissue and organ in your body. A complete protein, sirloin provides all of the essential amino acids your body needs.
Get Your B Vitamins
Ground sirloin, or beef in general, provides significant amounts of vitamins B-12 and B-6. These are important for brain function and energy metabolism. Vitamin B-12 plays an important role in red blood cell formation, neurological function and DNA synthesis. Adults need 2.4 micrograms of B-12 per day, and ground sirloin provides about 62 percent of this with 1.5 micorgrams per 3-ounce serving. Vitamin B-6 is also necessary for DNA production and making other genetic material. The general adult population needs 400 micrograms of B-6 per day, and ground sirloin provides 88 micrograms.
Selenium may play an important role in several diseases and disorders. Because of its antioxidant properties, it might be imperative in cancer prevention and cardiovascular disease. Selenium has an effect on DNA repair, cell death and the immune system, all of which may prevent cancer. The proteins from selenium can reduce inflammation and prevent platelets in the blood from aggregating, thereby reducing the risk of heart disease. At least 55 micrograms of selenium are recommended daily for the general adult population. A serving of ground sirloin provides 22 micrograms, which is about 40 percent of the daily value.
Lean is Best
Ground sirloin is a lean cut of beef compared to high-fat cuts, and the fat content can be comparable to what many consider "healthier" meats. For example, a 3-ounce chicken thigh has about 3.2 grams of saturated fat. In comparison, ground sirloin of the same serving size contains about 3.2 grams of saturated fat. A diet high in saturated fat has been linked to heart disease, so the less you have, the better. The 2010 Dietary Guidelines for Americans recommends consuming less than 10 percent of your daily calories as saturated fat.
