This is an interesting study. Small ‘N’ and some other questions but fount it worth looking at since I generally take a small amount of kefir (2 tbsp.) with an equally small amount of inulin (3g) each morning.
The study centers on a mixture of these prebiotics:
- arabinoxylan and cellulose/hemicellulose from psyllium husk
- beta glucans
- chitin and mannan from maitake mushroom
- arabinan from quinoa
- fructooligosaccharides (FOS) from beetroot
- glycyrrhizins and glycyrrhizin from liquorice root
- isomaltooligosaccharide (IMO) from miso
- pectin from orange peel
- xylan and galactan from spirulina
- resistant starch from arrowroot
- inulin from chicory
- xyloglucan from tamarind
- xylo oligosaccharides (XOS) from rice bran
- guar bean
- galactooligosaccharides (GOS) from chickpeas
