One of the known limitations in posting Tim’s American Gut Project results a while back was the fact that there was no “before” picture. While his results are pretty dramatic and way statistically suggestive of a large benefit conferred via his supplementation of resistant starch, it would still be nice to have a before & after comparison.
So now we have a chance to see that done. Allen Folz has created an indiegogo fund drive to do just that with four study subjects—two adults and two kids.
I will purchase two “Microbes for Four” swab kits from the American Biome Project.
At the start of the project four members of our family, two adults and two children, will provide a stool swab.
Over the course of a 6 week study period I will maintain a food journal for each participant and provide a daily diet supplement of resistant starch in the form of Bob’s Red Mill Unmodified Potato Starch. Each participant will follow a unique supplementation regimen:
a) adult 1 – 2 TBSP mixed in water, consumed on an empty stomach
b) adult 2 – 4 TBSP mixed in water, consumed on an empty stomach
c) child 1 – 1 TBSP potato starch plus 1 TSP whole psyllium husk mixed into yogurt
d) child 2 – 1 TBSP potato starch mixed into yogurt
At the conclusion of the study period the four test subjects will provide a second stool swab for comparison purposes. The lab results from both swabs will be shared publicly on the internet.
