Beef, the meat derived from cattle (Bos taurus), is a widely consumed food categorized as red meat due to its higher iron content compared to poultry or fish. This article provides a detailed overview of the nutritional composition of hamburger meat, its potential health benefits, and associated risks.
Nutritional Breakdown of Hamburger Meat
Hamburger meat, typically ground beef, is primarily composed of protein and fat, with varying amounts of vitamins and minerals. A 3.5-ounce (100-gram) serving of broiled ground beef with 10% fat content contains approximately:
- Calories: 217
- Water: 61%
- Protein: 26.1 g
- Carbs: 0 g
- Sugar: 0 g
- Fiber: 0 g
- Fat: 11.8 g
Macronutrients
- Protein: Beef is a high-quality source of animal protein, containing all nine essential amino acids necessary for body growth and maintenance. The amount of protein each person needs is influenced by several factors like age, sex, physical activity level, and overall health.
- Fat: Beef contains varying amounts of fat, also known as beef tallow, which contributes to flavor but also increases calorie content. The fat content depends on factors like trimming, animal age, breed, sex, and feed. Cooked lean meat contains around 12g of fat per 100g. Beef is mainly composed of saturated and monounsaturated fat, present in approximately equal amounts. The major fatty acids are stearic, oleic, and palmitic acids. Food products from ruminant animals, such as cows and sheep, also harbor trans fats known as ruminant trans fats. Unlike their industrially-produced counterparts, naturally-occurring ruminant trans fats aren’t considered unhealthy.
Vitamins and Minerals
Beef is rich in several vitamins and minerals, including:
- Vitamin B12: Essential for nerve function and red blood cell formation.
- Vitamin B6: Important for metabolism and immune function.
- Zinc: Supports immune function, wound healing, and cell growth.
- Selenium: An antioxidant that protects cells from damage.
- Iron: Crucial for oxygen transport in the blood. Beef is a rich source of heme iron, which is only found in animal-derived foods. Your body absorbs heme iron much more efficiently than non-heme iron, which is the type of iron in plant-derived foods.
- Niacin: Plays a role in energy metabolism and nervous system function.
- Phosphorus: Important for bone health and energy production.
Beef also contains copper, riboflavin, and choline in smaller amounts. Processed beef products like sausages may be high in sodium.
Other Meat Compounds
Beef contains bioactive substances and antioxidants that may benefit health when consumed in adequate amounts, including:

- Creatine: Important for muscle energy and performance.
- Taurine: An antioxidant with various physiological functions.
- Glutathione: A powerful antioxidant that protects cells from damage.
- Cholesterol: A structural component of cell membranes.
- L-carnitine: Involved in energy production and fatty acid metabolism.
- Choline: Important for liver function and brain development.
- Alpha-lipoic acid: An antioxidant that may improve insulin sensitivity.
- Coenzyme Q10 (CoQ10): Essential for energy production and antioxidant protection.
Potential Health Benefits of Including Beef in Your Diet
Beef, when consumed in moderation, can offer several health benefits:
Maintaining Muscle Mass
Beef is an excellent source of high-quality protein, which is essential for building and maintaining muscle mass. Animal protein may offer a slight advantage over plant-based proteins for building lean muscle mass because it contains all nine essential amino acids in sufficient amounts. In particular, beef contains leucine, an amino acid that plays a key role in developing the proteins necessary for muscle repair, growth, and regeneration. Eating high protein foods, such as lean beef, may help slow down age-related muscle loss, support recovery from surgery and exercise, and maintain and build muscle mass when combined with strength training.
Improved Exercise Performance
Carnosine, a compound important for muscle function, is formed in the body from beta-alanine, a dietary amino acid found in high amounts in fish and meat, including beef. High levels of carnosine have been linked to reduced fatigue and improved performance during exercise.
Anemia Prevention
Beef is a rich source of heme iron, which is efficiently absorbed by the body. Heme iron is only found in animal-derived foods. Some research indicates that meat can increase the absorption of non-heme iron even in meals that contain phytic acid, an inhibitor of iron absorption. Thus, meat not only contains a highly bioavailable form of iron but also improves the absorption of non-heme iron from plant foods, a mechanism that has not been fully explained and is referred to as the “meat factor.”
Potential Health Risks Associated with Beef Consumption
While beef offers nutritional benefits, high consumption has been linked to potential health risks:

Heart Disease
Observational studies on red meat and heart disease provide mixed results. A 2023 review found an increased risk for both unprocessed and processed red meat. However, observational studies cannot prove cause and effect. It’s possible that meat consumption is just a marker for unhealthy behavior, but negative health effects aren’t caused by the meat itself. Saturated fat has been proposed to explain the link between meat consumption and heart disease. The diet-heart hypothesis states that saturated fat increases your risk of heart disease by raising cholesterol levels in your blood. The diet-heart hypothesis is controversial, and the evidence is mixed. Not all studies observe a significant link between saturated fat and heart disease. Still, most health authorities advise people to limit their intake of saturated fat to under 10% of total calories.
Cancer Risk
Many observational studies link high meat consumption to an increased risk of colon cancer, but not all studies find a significant association. Several components of red meat have been discussed as possible culprits, including heme iron, heterocyclic amines (HCAs), and other compounds added to processed meats or formed during curing and smoking. HCAs are a family of carcinogenic substances formed during high-temperature cooking of animal protein, such as frying, baking, or grilling. Well-done and overcooked meat and poultry tend to have the highest levels. The National Cancer Institute states that eating cooked meats at high temperatures may increase your risk of various cancers, although research is mixed. Increased cancer risk may also be related to unhealthy lifestyle factors often associated with high meat intake, such as not eating enough fruit, vegetables, and fiber.
Other Health Concerns
- Beef Tapeworm: Consuming raw or undercooked beef may increase the risk of developing beef tapeworm (Taenia saginata).
- Iron Overload: Beef is one of the richest dietary sources of iron. In some people, eating iron-rich foods may cause a condition known as iron overload. The most common cause of iron overload is hereditary hemochromatosis, a genetic disorder characterized by excessive absorption of iron from food. Excessive iron accumulation in your body can be life threatening, leading to cancer, heart disease, and liver problems. People with hemochromatosis should limit their consumption of red meat, such as beef and lamb.
Grass-Fed vs. Grain-Fed Beef
The nutritional value of meat depends on the feed of the source animal. Compared to grain-fed beef, grass-fed beef may contain higher amounts of antioxidants, including carotenoids, ruminant trans fats, such as CLA, omega-3 fatty acids, vitamin E, iron, zinc, stachydrine, hippuric acid, citric acidsuccinic acid. Grass-fed beef may also contain less saturated fat, possibly making it a more nutritious, heart-healthy option.
Grass Roots is a collection of farmers throughout rural America who adhere to standards. Rotational grazing is the benchmark practice on most regenerative farms. Rotational grazing allows grass-fed cows' natural behaviors, like freely grazing on grass and forage at their leisure, providing improved animal welfare conditions. Grass-fed and grass-finished cattle eat grass and natural forage, and nothing else. Anecdotally, many people describe grass-fed beef as more robust, earthy, or even slightly gamey, as compared to the flavor of conventionally-raised beef. Several factors influence the nutrient content of grass-fed ground beef.
Practical Considerations
Any ground meat recipe you love can be prepared in exactly the same way, using grass-fed ground beef.
