Trish – That is not a term I have seen in our studies so I did some research of the doctors we follow (Campbell, Esselstyn, McDougall, Ornish and Greger). They talk about oxidative stress but I could not find any mention of “oxidative priority” in their literature or writings. In doing a (brief) Google search what I found seems to be related to eating an Omnivore diet. Can you share where you saw it or in what context?
