Weston Price
Many Studies 1940's
Weston Price
Price was a dentist. He realised that his American patients over 20 years has increasingly poor teeth and posture.
In the 1940s he travelled the world to find people who, firstly, had good jawbones and strong teeth.
Price found many groups of healthy strong tribal people: good teeth, no tuberculosis, no arthritis, no heart disease or cancer, strong bones, with upright stance. Gall bladder and kidney disease is rare.
People with a strong seafood culture, 
Weston Price identified as particularly healthy.
Healthy people ate lots of game, and ate it nose to tail. Their diet had very high mineral and vitamin content.
Price identified some super-foods: Insects, offal meats, fish eggs and bone marrow.
He made a special effort to find healthy groups with a vegetarian tradition and could find none.
All the diets he found that were healthy were nothing like the sort of diet we have been taught to believe is healthy. Since we're obviously not very healthy, we might ask ourselves what's wrong?
Stephen Phinney talks about how Inuit ate fat in their diets.
