Aside from posing the danger of E. coli, corn-fed beef contains far fewer nutrients than grass-fed beef. Prevention reports that a recent study by the USDA and researchers from Clemson University found grass-fed beef to be significantly higher in calcium, magnesium, beta-carotene, and potassium than corn-fed beef. In addition:
- Meat from grass-fed cattle is lower in both overall fat and artery-clogging saturated fat.
- Grass-fed meat is higher in healthy omega-3 fats. Meat from feedlot animals has been found to contain only 15-50 percent as much omega-3s as meat from grass-fed cattle.
- Meat from grass-fed livestock is four times higher in vitamin E.
- Grass-fed meat is higher in conjugated linoleic acid (CLA), a nutrient associated with lower cancer risk.
