Resistant Starch and Diabetes Experiment Day 25

I began a 30 day experiment of resistant starch and diabetes.  After only 25 days the results of the experiment are no longer in doubt and I just *had* to share! :)

  • if your blood sugars remain elevated, try resistant starch
  • Bob’s Red Mill Potato Starch is the resistant starch of choice


My personal experiment shows the positive effects resistant starch can have on your blood sugars, therefore potato starch can help you manage diabetes. I urge you not to eat a lot of high carb foods to obtain resistant starch, but to use Bob’s Red Mill Raw Potato Starch. (pic below)

I recommend Bob’s Red Mill because it is low glycemic, it won’t significantly raise your blood sugars.  There are foods which contain resistant starch, but they spike blood sugars, potatoes, rice, beans, etc.

If resistant starch is ‘new’ to you, have no fear… it’s actually an indigestible fiber. I provide links to more information at the end of this post for resistant starch newbies.

Now let’s look a the data.  I hope you will read this post and think… “I gotta try this!”  If not, why not?


Resistant Starch Diabetes Data


The picture below shows the data from 30 days of fasting blood sugar readings before taking Bob’s Red Mill Potato Starch on the top line.  And 30 days of fasting blood sugar readings after taking the potato starch for 30 days.  Potato Starch = Resistant Starch and I use them interchangeably.

The averages on the far right tell the tale. My average fasting blood sugars were 5 points lower!  I was already in normal ranges and it resistant starch lowered my blood sugars, what could they do to help you manage your diabetes?


day 25

There are so many variables with blood sugar it’s difficult to attempt to explain up and downs when you are talking less than 10 points.


Note:  Look at Day 5 and Day 16. On those days my Overnight Fasting Blood Sugars were great despite eating a high carb food the night before.  I also noticed that they trended higher for a couple of days too after eating a large Potato and Sweet Potato.  I’ll experiment with that again in the future to see if it holds up. You can also see that after a couple of days of trending up, it settled back down too. :)

Note: Lastly, see Day 25!?! … I finally made it into the 60’s with my overnight fasting blood sugar reading.  I’ve been in the 60’s many times these past 25 days, but this is the first Overnight Fasting Reading. :)


Charting the Effect of Resistant Starch


The ‘raw data’ above doesn’t really show the differences, but the graph below does. Clearly the red line is lower the vast majority of the time.

It’s pretty clear that the Post Resistant Starch use is lower than the 30 day data before using Resistant Starch.


Resistant Starch Diabetes Experiment


The bottom line: You (me, everyone) should obtain and maintain truly normal blood sugars.  If you can’t with or without drugs and insulin,  why not try Bob’s Red Mill?  You have nothing to lose and much to gain.

Here are other posts I’ve written on Resistant Starch, I suggest reading them in the ordered provided. :)

So, I’ll ask again… if you are not at least trying resistant starch (potato starch) … why not?  The data is pretty clear.  Potato starch can be a tool to help people manage diabetes.

Your results may vary from mine.  They may not be as positive… but then again they may exceed mine.

Wishing you all the best.


PS: I take Bob’s Red Mill Potato Starch as Richard Nikoley suggested.

This experiment nor this test is about ‘safe starches’ (for me)… I know that potato, rice, yams and sweet potatoes raise my blood sugar, I’ve tested them before.  THIS is about experimenting with ‘potato starch’.

I want to THANK Richard Nikoley again for pushing the benefits of Resistant Starch, Here is his Primer.

If your blood sugars are elevated and you cannot achieve truly normal blood sugars with diet alone…
