Episode notes
Small Serving, Big Risk Reduction
- A pooled analysis of 17 studies found higher intake of cruciferous vegetables cut colon cancer risk by about 17%.
- The strongest benefit appears at just 40–60 grams daily, roughly half a cup of cooked broccoli.
Biology Behind The Benefit
- Crucifers contain glucosinolates that convert to sulforaphane and indole-3 when chopped or chewed.
- These compounds activate detox enzymes, downshift cancer survival signals, and slow abnormal cell growth.
Gut Barrier And Microbiome Link
- Crucifer compounds tighten junctions between colon lining cells and lower inflammation.
- A stronger barrier reduces toxin translocation and supports a microbiome linked to lower cancer risk.
