Method: Shotgun metagenomic sequencing (CLIA 21D2062464); not cleared or approved by the FDA. Results reflect relative microbial abundance for wellness education purposes. Not intended to diagnose or treat disease and not a substitute for clinical consultation. Microbial associations are based on emerging scientific research and may change over time. Derived from laboratory results. This score or index is not an FDA-cleared test. It aids clinician-directed assessment and is not a stand-alone diagnosis.
A derived biomarker is a value that is calculated from other directly measured biomarkers rather than being measured directly in the lab.
Key benefits of Resistant starch testing
- Resistant starch fermentation capacity tracking
- cooked and cooled food microbiome benefit potential
What is Resistant starch?
This metric estimates your gut microbiome's functional capacity to ferment resistant starch - a type of dietary fiber that passes undigested to the colon where it is fermented by specific bacteria. Estimated from relevant enzyme-encoding genes by shotgun sequencing.
Why is Resistant starch important?
Resistant starch is a potent prebiotic found in cooked and cooled potatoes, rice, legumes, and green bananas. Fermentation of resistant starch produces butyrate and other beneficial SCFAs. Microbiome capacity to ferment resistant starch reflects the presence of key taxa like Ruminococcus bromii.
What insights will I get?
Your resistant starch fermentation capacity may indicate how well your microbiome can benefit from resistant starch-rich foods. Low capacity may suggest reduced Ruminococcus bromii or related taxa - potentially addressable through increased dietary resistant starch intake.
