If veganism works for some people, great! However, grass-fed beef is a health food when eaten in moderation.
“Ground beef is a good source of protein, providing 22 grams per 3-ounce serving.
Vitamins and Minerals
Beef is a good source of carnitine, zinc, selenium, iron, and B vitamins. Because your body can't store or produce B vitamins, you need to consume them in your diet.2
Carnitine is a general term for several compounds including L-carnitine, acetyl-L-carnitine, and propionyl-L-carnitine. This nutrient is crucial for energy production since it transports long-chain fatty acids into the mitochondria to be burned, producing energy.3
Health Benefits
The primary health benefits of beef come from the significant protein that it provides, as well as its vitamins and minerals.
Helps Build Cells
Protein is essential for maintaining muscle tissue and for various biological processes in your body daily. This macronutrient helps your body build bones, muscles, cartilage, skin, and blood.4 The selenium in beef is also essential for DNA synthesis.
Boosts Immune System
Beef contains several B vitamins, including thiamin (B1), riboflavin (B2), niacin (B3), pyridoxine (B6), folate (B9), and cobalamin (B12). These B vitamins and zinc in beef are essential to maintaining a healthy immune system.
Supports Hormone Production
The B vitamin niacin also aids in the proper function of many body systems, including the production of sex hormones. Selenium is essential for thyroid function.
Replenishes Iron Stores
Your body needs iron to help make red blood cells, among other functions. Dietary iron comes in two forms, non-heme, and heme—which is found in beef and other animal proteins. Heme iron is easier for the body to use, so you don't need to consume as much of it (vs. non-heme iron) to help stave off anemia and other problems stemming from low iron.”
