Gut Bacteria, the Metabolite Produced and Diabetes

This website is dedicated to giving you the latest information about using food to prevent and control, or better yet reverse diabetes. It also documents my journey with diabetes.

Today I will share with you a brief summary of yet another research. This time we are looking on our gut and an intestinal bacterium which could be the answer for some diabetics.

Indolepropionic Acid

This research took a look at gut bacteria, the metabolite produced and diabetes. Yes, it is believed that we have an intestinal bacterium which could protect us from diabetes.

The research was done by the University of  Eastern Finland. Indolepropionic acid is a metabolite which keeps type 2 diabetes at bay.

The good news is that this acid is produced in the intestine, especially when we eat a lot of foods which are rich in fiber. Yes, I share your excitement!

High Fibre Foods at it Again

I keep saying the same thing. Mother Nature has given us all the foods for our healing. I am always amazed that high fiber foods are the answer for a number of illnesses.

Yes, the fix is really simple. We need to eat more fiber-rich foods.

Results from the Study

Please see below for some notes from the study:

  • Two (2) groups were compared.
  • There were 200 participants.
  • The study looked at the result after five (5) years and then after fifteen (15) years.
  • They were overweight.
  • The participants were glucose intolerant.
  • The participants who ate a lot of grains and other high fiber foods had more of the indolepropionic acid than those who ate less fiber filled foods.
  • Those with more of this acid saw a greater secretion of insulin by the beta cells in the pancreas.
  • Please note that two (2) earlier studies were done and the results were the same, indolepropionic acid guarded against the risk of diabetes.

    Thanks for this wonderful information. I am going to share this site with my aunt who has type 2 Diabetes. I am not much into fermented foods, but I guess it may be time to try these out. Pretty interesting study you shared too. I will definitely come back to read up on the great information you have for us.

    As one who has type 2 diabetes, I honestly had no idea “gut” bacteria was this important to controlling diabetes. It’s a shame that I don’t like to eat most of the beneficial foods you mentioned. Good article.

      Michael, maybe you should explore different recipes and see if you will be able to eat some of the foods you are not eating now. I hate pumpkin, but when I crush it and melt my favorite cheese on top, then I absolutely love that as my breakfast. It keeps my sugar level low and that is just great. Keep me posted.

    Hi Josephine. Great article here, diabetes is becoming a very common illness that’s affecting a lot of people. I will say though, I’m usually all about trying new foods, but the first time I tried Kombucha the texture really got to me. DO you know if there’s a way to get the nutrients from the probiotic foods into a shake or smoothie that will give you the nutrients but also hide the taste?

      I just add things like yogurt to my smoothie. I avoid the foods I hate to eat, unless I experiment with the recipe, or how I use the food. I think we got a variety to suit the different preferences dictated by our taste buds. I love yogurt and sauerkraut, so I stick with those.
