Anecdote from NZ history - in areas where aruhe (the rhizome of the bracken fern) or shellfish were a staple food, a leading cause of death in Māori was septicaemia - blood poisoning from tooth abscesses caused by a diet high in materials that were damaging to teeth - the tough fibres in the aruhe, and the sand in the shellfish.
