Resistant Starch Testing Project

Dear Readers – I’ve been trying to get this project started for almost two years, and finally have the time to do it.

Indiegogo Project: Resistant Starch Testing

Many of us have been using things like raw potato starch, green banana flour, and Hi-Maize in our fiber supplements, but these starches are not routinely tested for RS content.

I’m hoping to raise enough money to get these starches, and others, tested for RS content. My goal is to raise $20,000, but this will require lots of big donations from research labs and supplement manufacturers, if you all would like to donate, I won’t turn it down!  If the “big guys” don’t come through, we could get some meaningful data with as little as $200.

This is 100% non-profit, meaning 100% of money gathered will go towards testing and “perks.” Please forward to anyone you know who might be interested in the results and could help with funding…your alma mater, perhaps, or bloggers and websites concerned with fiber and gut health. If they get duplicate requests, maybe it will show them that this is important.

I’ll be working non-stop to find donors, any help ya’all can give in this area would be awesome.

Here’s the intro video (Click here to see the project and donate):

    You say that your goal is $20,000, but that this would require donations from large players. What are you thinking in terms of small players? That’s a lot of money. What would be a successful campaign for you? How about a breakdown of costs?

    I am most likely one of your biggest supporters (wife willing), so I’m asking of genuine interest. The large sum surprised me, so I’d like to be educated.

      A single test costs $150-175 depending on the lab I use, plus shipping and purchasing the starch. Indiegogo gets 5%. So, roughly $200 for a single test.

      If I raise any money, no matter how little, I’ll pony up the rest to get a sample of Bob’s Red Mill RPS tested. I realize this will not be enough for publishing in a paper, but it would but my mind at ease that at least RPS is a good source.

      Conversely, if the test came back showing considerably less than the hypothetical 65% RS, it would tell us that we need to rethink using off-the-shelf starches, and demand some manufacturers to develop a product that is tested and labeled with RS content.

      I really did not want to pressure you guys to fund this. My hope is to get some big donations from research labs/supp manufacturers. So, maybe, a better way for you guys to help out is to forward this around to labs and supp makers. I’ll be Googling every day for email addresses and looking at all of the papers for names and email addresses to send this to. I’m hitting up all the bloggers and researchers I know.

        Wilburs surely means that ‘breakdown of costs’ should be included at your Indiegogo page.

    If all your regular readers donate $25 each, you would have your funds. I would love to donate $25, but as an overseas reader both of us would face bank charges and that would defeat the purpose. I recently found this out to my cost.

    I watched your film, and saw you hold up a what I thought was a probiotic, and quite b y chance when looking for something else, I found a Dutch supplier !! I will give it a try. By the way would the manufacturer of that product be willing to subsidise the testing of their product?

      If a 1000 US readers were to donate $25 each you would have raised $25.000 !!

      I contacted Natural Stacks, hopefully they donate.

    What an excellent idea! Some companies out there must need this information to make an economical, reliable prebiotic product. I’ll look forward to reading this again and really thinking it over, doing what seems fitting.—-Terri F

    Hi Tim,
    Glad you got your project rolling 🙂
    Ignore the email I sent regarding the indiegogo payment gateway.
    Just seen the PayPal Donate function on your site and did a test with that right now.
    Let me know if it goes through to the right place, as it appears to be separate to indiegogo.
    Good luck with the project!


    • Tim Steele January 26, 2017 at 7:34 am #

      Yep, it’s there. Thank you good sir. Yes, the PayPal is completely separate from Indiegogo, but I will make sure everyone gets the same perk. Strange that Indiegogo cannot be accessed from the UK.

    I bought a Walmart blood glucose meter kit at the suggestion of Dr. Willim Davis. My fasting glucose is usually in the 90-100 mg/dl range. A few years ago it was 76.

    I have gone through two packages of Bob’s Red Mill potato starch before I got the meter.

    I pressure cooked a few mini potatoes in my Instant Pot then refrigerated them for 2 days. I re-heating the potatoes for 123 sec. and ate them with butter, salt and pepper. At 45 min.– blood glucose was 175 mg/dl. I considered this to be a failure as the starch was rapidly converted to glucose.

    A medium Yukon Gold sliced thinly and eaten raw with salt —the blood sugar was down 2 mg./dl at 45 min.

    For about $30, you can get set up for self testing your blood sugar with a good meter. The needle gun makes the stick painless. Dr Davis says the important number id comparing the glucose concentratio immediately befor and 45 min.1 hr. after ingesting the meal or food.

      Good experiment. Cooked and cooled potatoes still contain a good amount of readily digested starch, that’s a fact. Raw potatoes have none. 175mg/dl at 45 min post-prandial is not shocking and does not indicate much on its own. Your FBG of 90-100 is a tad on the high side, but far from even pre-diabetic.
      Thanks for the notes!
