I just finished watching "forks over knives" and thought there was a lot of great information presented in the video. One question i was really hoping they would address, but never did, is the difference between grass fed and corn fed cattle and their by products. I am 25 years old and have lived and worked on a organic, cattle farm. We only have about 50 head on roughly 300 acres and my parents are always forwarding me articles about the benefits of grass fed over grain and corn fed red meat. I would just be curious to hear your thoughts on the difference and why you thought it was never mentioned in the movie. Thanks
