The short answer
Dr. Martin says no, and that it is not close. On his numbers beef carries 78 percent less omega-6 than chicken and 125 percent more creatine, and he still eats chicken, he just does not rate it above beef.
Dr. Martin comparing beef and chicken:
Dr. Martin, The Doctor Is In, Episode 1767Beef, steak, has 78% less omega-6 than chicken. Chicken has a lot of omega-6. Now listen, like I said, do I like chicken? Yep, I do. Okay? Is it better than beef? It's not close. It's not close.
Hear it on the episode: YouTube, The Doctor Is In episode 1767
Why the omega-6 number is the one he leads with
Omega-6 is the figure he puts first, ahead of protein or fat or calories. He is not telling anyone to stop eating chicken, he says plainly that he likes it. The point is the ranking, and on his ranking beef wins on the things he measures.
The other reason he keeps going back to beef
The second reason is B12, and it runs through his whole answer on red meat.
Dr. Martin, The Doctor Is In, Episode 698If B12 is only found in red meat, you'll never being healthy without B12, not fully, you can't. Because your body relies on B12. Your nervous system relies on B12. Your immune system relies on B12. Your brain relies on B12. Your blood vessels rely on B12 because B12 helps open your blood vessels, relaxes your blood vessels in the form of nitric oxide. How on God's earth can red meat be bad for you?
