Grass-fed beef provides many benefits that cannot be found in commercial, grain-fed beef. Compared with commercial beef, grass-fed beef is lower in calories, contains more of the "good" fats and fewer "bad" fats, is richer in antioxidants and doesn't contain added hormones, antibiotics or other drugs.
Lower in Fat and Calories
Meat from grass-fed cattle is lower in total fat; it can have as little as 1/3 the fat as a similar cut from a grain-fed animal. Grass-fed beef has about the same fat content as skinless chicken thighs, wild venison or elk. And because grass-fed beef is lower in fat, it is also lower in calories. Fat has 9 calories per gram, while protein has only 4 calories per gram. If everything in your diet remained the same but you switched from grain-fed to grass-fed beef, you'd lose about 6 pounds per year.
Abundant Healthy Fats
Grass-fed beef has three times more omega-3 fatty acids than grain-fed beef. Omega-3s are called "good fats" because they play a vital role in every cell and system in your body. Omega-3s help reduce blood pressure, prevent cardiovascular diseases, maintain healthy brain function, prevent and/or slow the growth of many cancers, and prevent arthritis. Grass-fed beef also has fewer saturated fats which are associated with heart disease, and a better ratio of omega-3 to omega-6 fatty acids.
Higher Levels of Vitamins and Minerals
Grass-fed beef contains 10 times more beta-carotene than corn-fed beef, and studies have shown that beta-carotene is important for stimulating the immune system and maintaining healthy vision, skin and bones.
You'll receive triple the amount of vitamin E when you eat grass-fed beef. Vitamin E is linked with a lower risk of heart disease and cancer. This powerful antioxidant may also have anti-aging properties. Most Americans are deficient in vitamin E.
Higher levels of the essential minerals calcium, magnesium and potassium, as well as higher levels of B-vitamins thiamine and riboflavin, are also found in grass-fed beef.
