Grass fed beef has been revealed as a more nutritious beef product. There are a number of reports that show grass fed beef products contain elevated concen-trations of carotene, a-tocopherol, a more desirable omega-3:omega-6 ratio, increased levels of conjugated linoleic acid (CLA), all substances reported to have favorable biological effects on human health.
• Vitamin A: B-carotene levels are 10 fold higher for grass fed beef compared to grain fed beef.
• Vitamin E: alpha-tocopherol levels are 3 fold in forage finished beef.
• Omega 3: Omega 3 fatty acids are increased by 60% and produces a more favorable omega-6 to omega-3 ratio.
• Conjugated Linoleic Acid (CLA) grass fed beef have been found to produce 2 to 3 times more CLA than those beef feed grains and concentrate feed. On average grass fed beef will provide approx. 123 mg of CLA for a standard hamburger at 10% fat. The same hamburger produced from grain fed beef would provide 48.3 mg.
