Nathan T. asks Plenty Magazine. . .
The response (in a nut-shell):
Most cattle ranchers focus on getting their cows fat as quicky and cheaply as possible. That means stuffing them with synthetic hormones and corn-based feed instead of letting them roam and feed on grass as nature intended. Their diet which contains corn and stuff you don't even want to hear about, causes ulcers and acidosis. To keep the cattle alive until slaughter, they are fed plenty of antiobiotics (which you then ingest).
Pasture-raised, grass-fed beef comes from healthier, leaner, and more humanely treated animals. It also has more vitamin A, and Omega-3 fatty acids. Plus cows that are free range fertilize their pastures, creating healthy land that actually removes CO2 from the air. Check out American Grassfed Association. Find farmers at your local greenmarket and ask if its grass fed.
