Grass Fed Beef Benefits
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.
Corn vs. Grain
All cows do graze on pasture for the first six months to a year of their lives, but most finish at a feedlot on a concentrated mix of corn, soy, grains, and other supplements. This growth-spurt formula is the backbone of a hugely productive U.S. beef industry. A feedlot cow can grow to slaughter weight up to a year faster than a cow fed only forage, grass, and hay. "That's one year that you don't have to feed the cows in the feedlot," notes Eatwild.com founder Jo Robinson, who spent the past decade examining scientific research comparing grass-fed and grain-fed animals.
