Vegemite, Marmite, Yeast Extract and Nourishing Traditions, Paleo or GAPS

[Loveinamist]

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?

Glutamate
Vegemite, like many foods including tomatoes, cheese, mushrooms and meat, contains unrefined glutamate[1], not to be mistaken with Mono-sodium Glutamate (MSG) -- a salt-bound, chemically-refined form of this flavour-enhancing natural amino acid. Vegemite contains 1.4% of unbound, natural glutamate amino acid, and an unknown quantity of the bound form, which also occurs naturally in many common foods.

From some site caled wiki cookbooks or something. But all the info is about 50/50 so I couldn't say for sure, it does have a lot of salt though
