Why do we focus so much on getting ROS down with fasting? Its for sure one way to get rid of it (temporarily) I think we need to understand the reason for that ROS / high fission.
To some extent, ROS is normal.
Its like Blood pressure.
Its not about to lower it in general. Its about to know why its not regulating anymore. Always high is not good. As is always low.
Epithelial barrier function in UC is damaged.
Once ROS increases, ROS can go near that barrier.
Immune system reacts (too) quickly on that "pathogen" because of that reduced "safety space" (barrier).
With H2o2, that barrier cant get repaired. ->

H2o2 working like a desinfectant reduces SCFA producers and beneficial bacteria.
If Acetate, Propionate and Butyrate as HDAC inhibitor is missing, fission is high.

So no resistance against ROS. Always full immune system reaction (+histamine). And no stop to fission because of no SCFA.
-> More ROS
I think with a good barrier, and therefore without the immune system reaction, SOD CAT Glutathione could all work to get rid of ROS. (With help of histidine

)
So mito fission would lower itself after that. And there would be no need for TCells and Histamine and all that crap. It would be regulative.
But with that missing barrier, which acts like a open wound, even the smallest increase in metabolism produces enough ROS, which will go as "detected pathogen" on that barrier.
And if you have high ROS and ongoing inflammation, all histidine will be used for Histamine (h2o2-> increased HDC).
Thats why you wont get into a flare that easy when you are in remission for some years.
But if you get flare after flare, your histidine will depleted and all antioxidant defensive mechanisms are low.
Basically Butyrate is the barrier against ROS and the brake for mitochondrial fisson which causes ROS.
Inhibition of butyrate oxidation in experimental animals resulted in mucosal inflammation similar to ulcerative colitis.
I think we should focus more on SCFA in the gut. Butyrate is regulating mitochondrial fission and fusion in the gut.

Butyrate is doing everything we want. And if we want to lower ROS and fission local in the gut. -> its butyrate thats missing local in the gut thats doing that.
Inuline which increases Butyrate, but only really slow, stopped my UC flare in 2 days. And it stopped ~8 months flare from
@wuf in only a few days too.
I think we should not leave that behind.
Again what Butyrate does:
-preservation of gut barrier functions
-protection against pathogens by producing bacteriocins
-resistance to oxidative stress (ROS)
-inhibition of nuclear factor κB
-regulating IL-1b, TNF-α, IL-2, IL-6, IL-8, IL-12
-produce vitamins, antioxidants, polyphenols, and conjugated linoleic acids
