Reddit mentions of Bob's Red Mill Potato Starch, 24-ounce (Pack of 4)

I am very glad to hear you found something that relieves your symptoms.

I can tell you why this works.

Green bananas contain a lot of resistant starch.
Resistant starch can be very powerful tool in helping your colon.
It is food for your bacteria.
Another easy way you could do this is by buying raw unmodified potato starch.

Other sources of resistant starch see: http://freetheanimal.com/wp-content/uploads/2013/08/Resistant-Starch-in-Foods.pdf

Always make sure to start very slowly with this, as it can cause gas when first starting!

edit: I forgot to mention you can also buy banana flour! https://www.amazon.com/WEDO-Gluten-Free-Banana-Flour/dp/B00HGJ7VAU/ or https://www.amazon.com/Green-Banana-Flour-Prebiotic-Gluten/dp/B01CJ5OEFU/

Like /u/junkbot said Bob's red mill potato starch is something like 80% RS. That's really good and if you're using a few TBSP you'd only get a few extra carbs.

Whole foods? No I agree, barely any compared to the amount of carbs in them.

Hey,

I've decided to add some resistant starch to my diet to help feed those little buggers down in my intestines. This is a general guide:

And this has a great video (made by Aussies!):

I've got a bag of Bob's and am going to start today:

I hear that the initial downside is that it can make you gassy initially, but the benefits outweigh that.
