Thank for watching the video. I also grew up on a small farm and in a hunting environment and didn't think anything of it at the time. I've written a bit about it before. The China Study is probably the most well known long term study about nutrition and how different diets affect health. It's available on Amazon. The works of doctors Neal D. Barnard, Caldwell Esselstyn, Michael Greger and John A. McDougall also follow the same train of thought. I also highly recommend this presentation by Dr M. Greger about the Leading Causes of Death quoting a bunch of studies: http://nutritionfacts.org/video/uprooting-the-leading-causes-of-death/ actually the whole website http://nutritionfacts.org/video is excellent and has a wealth of nutrition information based on scientific studies.
