Score Ten for Grass-Fed Beef
Grass-fed beef is better for human health than grain-fed beef in ten different ways, according to the most comprehensive analysis to date. The 2009 study was a joint effort between the USDA and researchers at Clemson University in South Carolina. Compared with grain-fed beef, grass-fed beef was:
- Lower in total fat
- Higher in beta-carotene
- Higher in vitamin E (alpha-tocopherol)
- Higher in the B-vitamins thiamin and riboflavin
- Higher in the minerals calcium, magnesium, and potassium
- Higher in total omega-3s
- A healthier ratio of omega-6 to omega-3 fatty acids (1.65 vs 4.84)
- Higher in CLA (cis-9 trans-11), a potential cancer fighter
- Higher in vaccenic acid (which can be transformed into CLA)
- Lower in the saturated fats linked with heart disease
