Here is an interesting documentary on tribal people and their food habits done by a famous Australian Youtuber with the channel ‘besteverfoodreviewshow’. This Australian YouTuber claims that The Tribe has been practicing cannibalism, however some of them have disputed against the statement.
On the other hand, Korowai tribe lived in communal tree houses in the Jungle canopy and as of now, they are turning to settled villages. These communities lead interesting lives resourcing everything from nature. They hunt their own food, build their own treehouses and live on the edge of life. They dig in worms and eat them as their daily food! They believe that these worms have microbes in them which detoxes your body and fills you with healthy nutrients!
Watch this video and see for yourselves. They are so much better off without all the development and industrialization!
