Resistant starch
For supplementing fermentable fibres
The experts we follow agree on this.
Resistant starch can support gut health, but individual responses differ.
Who is behind it
Voices including a former research biochemist, a Princeton-trained molecular biology PhD and a licensed acupuncturist and clinician-educator.
How strong the research is
Mostly expert experience so far, with published research still catching up.
In their words
“baked potato cool it overnight in the refrigerator and then you can eat it the next thing you can even heat it up and it doesn't undo the resistant starch”
