Grass-Fed Beef: The Superior Protein
Overall, grass-fed cattle are healthier than grain-fed cattle. The livers of grain-fed cattle have a 30-fold increase in abscesses, 8-fold more blood vessel disorders and a 3-fold greater frequency of liver contamination (Roberts 1982). Many clinical studies have compared the nutritional content of grass-fed to grain-fed beef. Beef from grass-fed cattle has been shown to have better overall quality in terms of color, lipid oxidation and alpha-tocopherol levels than beef from maize-fed cattle (O’Sullivan 2002). This study found that maize-fed beef had the poorest color while grass-fed beef had the best. Lipid oxidation, which has negative impact on beef flavor, color, and nutritional value, was highest in maize-fed beef and lowest in grass-fed beef. Alpha-tocopherol concentrations (the form of whole food vitamin E that is preferentially absorbed in humans) were also highest in grass-fed beef and lowest in maize-fed beef."
