Cauliflower

Overview
Cauliflower is a cruciferous vegetable providing glucosinolate-derived compounds, vitamin C, folate, and fibre at very low energy density [1]. Crucifer isothiocyanates activate Nrf2-linked antioxidant gene networks [1].
Within the BRAIN Diet framework, cauliflower is a low-calorie crucifer substitute in diverse vegetable patterns; folate supports methylation-related pathways
Key Nutritional Highlights
- Crucifer isothiocyanate / Nrf2 interest at very low energy density [1].
- Vitamin C and folate per 100 g; useful in low-carb vegetable diversity [2].
- Milder flavour than broccoli; still requires glucosinolate → ITC conversion for sulforaphane-class effects [1].
- Roasting acceptable; avoid heavy charring of any crucifer.
Food Context
Synergies
- Part of diverse cruciferous intake; dietary diversity (≥30 plant foods per week) supports microbial richness and resilience
- Pair with fat for fat-soluble vitamin absorption; dietary fat enhances the absorption of fat-soluble vitamins
Preparation
- Can be consumed raw, roasted, or steamed; light cooking may preserve some compounds
- Supports gut health via fiber; prebiotic fiber supports Bifidobacterium, Akkermansia; ↑ butyrate production; improved gut barrier

Bioactive compounds
| Compound / class | Amount per 100 g | Notes |
|---|---|---|
| 5-Methyltetrahydrofolate | 92 µg | — |
- 5-Methyltetrahydrofolate: Supporting evidence and original measurement details are available in technical provenance below. [Reference]
Technical provenance
5-Methyltetrahydrofolate: Calculated from the reported Table 5 molar sum, not directly reported mass concentration. Includes polyglutamate species as monoglutamate equivalents, not their intact molecular masses. Glu8 response was estimated by calibration extrapolation; no Glu8 was detected in this cauliflower sample. Analytical steaming was extraction treatment, not a cooked-food state. One study sample does not establish universal food composition; do not add this vitamer value to total folate as an independent nutrient supply. [Reference]
