You guys crack me up.
I agree completely with the Iowa caucus on the beef topic. I've tried to enjoy grass-fed beef a few times, but it's just not as luscious as grain-fed.
Grass fed cattle are walking around, looking for food, and spending more energy to digest it once they find it. Grain-fed cattle are just standing around easily converting delicious corn into pure, fatty yumminess.
I don't think that the health benefits of grass-fed beef are going to be "enough" to warrant a switch. If you want healthier red meat, perhaps Elk or Buffalo would be a better choice.
But, well, I'm just an enthusiastic omnivore, not a scientist.
