Resistant Starch, Peripheral Serotonin & Diabetes

Written by Joe Cohen, BS | Last updated:


I already told you about how resistant starch is a particularly good fiber source for people who have the ancestral variant of the TCF7L2 gene.

But it isn’t just about fiber!

It turns out that people with the ancestral variant of the TCF7L2 gene also often have issues with elevated peripheral serotonin levels (this is a different kind of serotonin than the one found in your brain).

And do you know what high peripheral levels of serotonin have been linked to?


In fact, peripheral serotonin is now thought to play a possible role in modulating the immune system and maybe autoimmune diseases.

There’s good news though.

Resistant starch has been shown to help decrease peripheral serotonin levels!

If you’ve got this ancestral variant of the TCF7L2 gene, you really need to take preventative measures when it comes to diabetes, like adding resistant starch to your diet.
