Because grassfed meat is so lean, it is also lower in calories.
Fat has 9 calories per gram, compared with only 4 calories for protein and carbohydrates. The greater the fat content, the greater the number of calories.
A 6-ounce steak from a grass-finished steer has almost 100 fewer calories than a 6-ounce steak from a grainfed steer.
If you eat a typical amount of beef (66.5 pounds a year), switching to grassfed beef will save you 17,733 calories a year—without requiring any willpower or change in eating habits. If everything else in your diet remains constant, you'll lose about six pounds a year. If all Americans switched to grassfed meat, our national epidemic of obesity would begin to diminish.
Extra Omega-3s
Although grassfed meat is low in "bad" fat (including saturated fat), it gives you from two to six times more of a type of "good" fat called "omega-3 fatty acids."
Omega-3 fatty acids play a vital role in every cell and system in your body. For example, of all the fats, they are the most "heart friendly." People who have ample amounts of omega-3s in their diet are less likely to have high blood pressure or an irregular heartbeat. Remarkably, they are 50 percent less likely to have a serious heart attack.
Omega-3s are essential for your brain as well. People with a diet rich in omega-3s are less likely to be afflicted with depression, schizophrenia, attention deficit disorder (hyperactivity), or Alzheimer's disease.
Another benefit of omega-3s is that they may reduce your risk of cancer.
In animal studies, these essential fatty acids have slowed the growth of a wide array of cancers and kept them from spreading.5 Although the human research is in its infancy, researchers have shown that omega-3s can slow or even reverse the extreme weight loss that accompanies advanced cancer. They can also hasten recovery from cancer surgery. Source: "Why grassfed is best" published on www.americangrassfedbeef.com.
