Someone in the PEERtrainer community pointed out a quote from Dr. Oz that left them confused. He had said that nutritionally, there is not much difference between grass-fed beef and grain-fed beef.
We asked Brian to take a look at this question and look at the science. Here is what he found:
"What a strange thing for Dr. Oz to say... it's not as if there is a lack of evidence, or even contradictory evidence as can sometimes be seen in organic vs. conventional studies.
As far as I'm aware, there has never been a single study demonstrating that grass-fed beef has a similar nutritional profile to grain-fed beef.
Even those who support grain-fed beef will admit that grass-fed beef is leaner, as the reason we feed grain to cattle in the first place is because it fattens them up so well and causes marbling (the fat invades the muscle).
