Marmite Yeast Extract Spread is a Superfood for my Gatherer Genotype.  However, "Health Ranger" Mike Adams has complained that yeast extracts have glutamic acid in them. Anyone have any info/thoughts/feedback regarding this?  Thanks.  

Mike Adams tends to be a bit of a worrywort/sensationaliser from what I hear/read... Not everyone is affected by glutamic acid... Now if you were an Explorer it might be a different outcome...although tbh, being a nonnie can amount to a very similar thing

Although I am not familiar with this product, my husband who suffers migraine headaches and is sensitive to MSG must also steer clear of yeast extract.

make your own compliant, using nutritional yeast

there s a great recipe

Some people react strongly to glutamates. Others don't. Nutritional yeast (and products containing it) do contain natural glutamates, but are also very high in B vitamins. How nutritional yeast/marmite will rate for you depends on your need for B vitamins as well as your sensitivity to glutamates.

I've always avoided MSG because I read it was a toxic additive, and anyway it's generally found in highly processed foods that I wouldn't want to eat anyway. However, SWAMI rates it as neutral for me. I'm not about to buy MSG to cook with, but it's nice to know that MSG isn't a toxin for me personally.

I also get nutritional yeast as a superfood. I eat it liberally in my eggs. However, I don't cook with it for family meals because it's an avoid for my Explorer daughter. (I also don't feed it to my other daughter, who I suspect is an Explorer too.) Even though we're the same blood type and have similar family history, we're different individuals and react differently to glutamates.
