She goes deeper in her presentation at the 2016 International Conference on Nutrition in Medicine, and in this TEDX talk she gave a number of years ago. She brings up various points, going into her research analysis of ancient gut micro-biomes and more. She also brings up the fact that our digestive systems are clearly constructed to digest plants and fibres that require a longer processing time, not meat. They are much longer than those of meat-eating animals, and the fact that no adaptations exist within our digestive system to consume animal flesh is a crucial point.“Humans do not have any specialized genetic anatomical or physiological adaptations to meat consumption. By contrast, we have many adaptations to plant consumption.” (The Game Changers documentary)
There are many facts that Dr. Warinner points to in her research, like how humans cannot produce their own vitamin C, which is one of many factors indicating just how reliant we are on plant foods for certain vitamins. There is nothing essential within meat that cannot be found within plant foods. Some may point towards vitamin B12, but B12 isn’t made by animals.
B12 is made by bacteria that all animals consume. It’s found in the soil and in water. It’s the same as protein, as all protein originates from plant sources, which is how the animals that people eat actually acquire their protein in the first place. Before industrial farming, humans and animals got their B12 from the traces of dirt found on plant foods or by drinking water from freshwater lakes, rivers, and streams. As a result of pesticides polluting our waterways, forcing us to chlorinate our water among other things, the B12 bacteria originally in water has been killed off for the most part. Even farm animals are required to take B12 supplements. Both meat eaters and vegetarians/vegans are commonly found to be low in B12–it has nothing to do with eating meat.
Another common argument is that we need to eat meat for essential amino acids. This is simply false, as there are multiple plant sources where we can get all of our required amino acids.
There are many experts in the fields of anthropology, biology and all other sciences who have been creating awareness about the fact that ancient humans were not big meat eaters as they’ve been portrayed to be by mainstream education. This begs the question, where did this idea come from? Sure...
