Hey JamesS - thanks for joining!
As for Omega 6s - I didn't state that they were dangerous, just that from what I've read, the balance between 6 and 3 needs to be as close to 1:1 as possible. MDA promotes this, and the wiki link I provided indicates some benefits specifically to asthmatics, arthritics and cancer patients with a ratio closer to 1:1. From what I understand, the typical western diet (promoted by USDA/FDA and the medical community) has an unbalanced ratio which promotes body-wide inflamation. And yes, PB does promote a diet with plenty of meat and animal fat, but also informs that most meat and eggs and dairy (coming from grain fed critters) is high in Omega 6 - hence my supplementing with fish oil. Apparently, pastured, grass fed animals have a much more favorable level of Omega 3 and a traditional hunter/gatherer diet would provide a more optimal ratio. I think my 6:3 ratio was really unfavorable as I ate lots of chips, loved microwave popcorn and all kinds of processed crap. In fact, my supplement intake is very inconsistent, yet I am still able to stay off of the asthma meds.
As I mentioned, I don't have a science background, so can't debate the point really well. However, following this way of eating seems to be working for me. I'm in better shape than I've been for about 15 years and my energy level has increased substantially. So...probably won't be adding soy - but I will look into the links you've provided.
