About 150 years ago, farmers began feeding their herds substantial amounts of grain. The grass fed meats that our ancestors ate were considerably different nutritionally from most of the meat consumed in America now. Returning to a diet of pasture-raised meats will provide numerous valuable nutritional benefits.
Benefit 3: Conjugated linoleic acids (CLAs)
Health experts say that CLAs can play an important role in strengthening the immune system. The concentration of CLA is between two to three times higher in grass fed beef as compared to grain-fed beef, for equivalent weights. The amount of vaccenic acid is four times higher in grass fed beef. Vaccenic acid can be desaturated to CLA in the human body.
According to scientists at Clemson University, “Conjugated linoleic acids, specifically the cis-9 trans-11 isomer, has been shown to possess anticarcinogenic effects. In addition to potentially neutralizing cancer-causing substances, recent studies indicate positive effects of CLA in reducing inflammation, strengthening the human immune system, and lowering risks of heart disease.”
