Here’s what Health.com says, “It’s much leaner than its conventional counterpart. It’s also higher in key nutrients, including antioxidants, vitamins, and a beneficial fat called conjugated linoleic acid (CLA) that’s been tied to improved immunity and anti-inflammation benefits. Plus, grass-fed beef packs about 50% more omega-3 fatty acids than standard beef (although the amount is still far lower than the total omega-3s found in fatty fish like salmon). Grass-fed beef is also less likely to contain “superbugs”—bacteria that have become resistant to three or more classes of antibiotics—so it’s considered superior from a food safety perspective as well.”
