Grass-Fed Beef: The Superior Protein

"Not all beef has the same nutritional profile. The cattle used to produce beef have traditionally been fed diets of grain. However, many farms are switching from grain-fed to grass-fed beef because of the numerous proven benefits to human health.

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."
