I am trying to find my own version of Nourishing Traditions, GAPS and a Paleo diet. I am more or less just trying to avoid unhealthy foods but not strictly following these diets ITMS So after googling for ages I still haven't found an answer to whether Yeast Extract, Vegemite or Marmite would be suitable or if it is a no no because it is processed at too high a temperature so therefore contains MSG (unintentionally)

Does anyone know?
