what i wonder is whether consistent mushroom consumption may actually flip the enzyme over. that is, i wonder if the way to digest mushrooms is to eat more mushrooms.
that said, the reason i'm not getting good results is that there seems to be some thinking that an inability to digest chitin is tied to lower levels of respiratory diseases, which is easy enough to understand, if you recognize that humans have a long history of living in crowded, unsanitary conditions. that is, the thought is that the mutation is linked to lower levels of respiratory illness because it better deactivates invading molds and whatnot, that enter your body as fungi spores from the air. the thought is that reversing the mutation might make us more susceptible to infection. it's at least a coherent explanation as to why we have this mutation and no other species does; we're the only species that lives in moldy huts.
if that's true - and it's not established that it is. - then we'd essentially be trading off the ability to digest mushrooms for a greater protection from air-borne fungus.
whether that is true or not, i would nonetheless call for some research into the question as to whether eating more mushrooms leads to greater expression or not. i mean, most of us eat almost no fungus (except dead yeast). so, if we don't eat any fungus, why do we need to create enzymes to digest it? we're better off protecting ourselves from air-borne spores. sure. but, can we undo it?
this article seems to suggest we can:
....but it's not the focus of most research on this. the research dollars are about asthma.
so, i'd call on some more serious research, especially as we have more and more asians that eat more and more asian food - are they getting anything from this at all, or is it just fibre?
i'm going to make some eggs and get on the b6 after.
