I've been a fan of the Nutrition Diva for a long time. I especially love the way she looks into facts versus what "everyone knows" (a.k.a. "myths) on different topics.
This time she's looking at grain-fed beef, In particular 3 myths and 1 surprising truth about the impact of various feeding programs on the health of the cow and on the environment. That's an area where there are a lot of misconceptions. And I was really surprised by the truth ... also pleased.
You can listen her podcast episode or read the transcript — both are at Nutrition Diva.
