Hi,
so as most of you know, I'm tube fed. Tube feeding mainly consists of cheap nutrients, no matter which brand you choose.
But: My concern after a recent discussion are the fatty acids. (My) As it comes to those, my tube feeding consists of 50% MCT oil, the rest consists of rapeseed oil and sunflower oil. So a lot of PUFA.
The attached article summarizes some research on essential fatty acids, especially oils.
So that is a concerning reading. As we know, oxidative stress and possibly proton lacks are a problem in ME/CFS. What I take away from this article is that my tube feeding might hold me back from getting better, further destroying my cells and as a consequence causes more harm than I already have.
The article itself is very drastic. It extends the harmfulness of fatty acids to include essential fatty acids and states that our daily need for fatty acids disappears (0.5-1%).
All in all my question is: the combination of high amounts of maltodextrin plus the fatty acids might be an explosive mixture that makes things worse or at least holds me back from getting better.

Nevertheless, a substantial portion of dietary PUFA still accumulate over time in cell membranes (88).
Perhaps the reason the mammalian body appears to be hard-wired to get rid of the bulk of these fatty acids is because their excessive inclusion in cell membranes presents an oxidative liability that can wreak havoc on the cell.
PUFAs are fatty acids that contain two or more double bonds between carbon atoms. Double bonds make a fatty acid very easily oxidized – that is, they make its electrons easily stolen by free radicals. Because the typical oxidation reaction that occurs in cell membranes requires the presence of two double bonds positioned near to one another, it is primarily PUFA rather than monounsaturated fatty acids that are vulnerable to oxidation (see Figure 3 on page
22). The more double bonds they have, the more susceptible they are. Oxygen binds to PUFA at the site of the oxidized double bond, turning the fatty acid into a peroxyl radical. Peroxyl radicals initiate chain reactions within cellular membranes by interacting with other PUFA; in each reaction, the peroxyl radical becomes a lipid peroxide and the second PUFA becomes a peroxyl radical that can go on to react
with a new PUFA; the cycle continues, repeating this process. In the presence of certain metals, the lipid peroxides will break down completely into products such as MDA (see Figure 3 on page 22), which
can infiltrate the rest of the cell to damage proteins and DNA. Lipid peroxides themselves can be enzymatically cleaved from the membrane and cause damage to the rest of the cell.
