Cauliflower

Cauliflower is listed as a source of vitamin C (26 mg per 1/2 cup raw, ~43% DV).

Why It Matters for Longevity

Cauliflower is listed as a source of vitamin C (26 mg per 1/2 cup raw, ~43% DV). Vitamin C is the primary water-soluble antioxidant in plasma; required for collagen biosynthesis, immune cell function, and regeneration of vitamin E; protects against oxidative stress associated with aging.. Frequent consumption of cruciferous vegetables including cauliflower was associated with a statistically significant reduction in lung cancer risk (OR 0.72), attributed to isothiocyanate-mediated induction of phase II detoxification enzymes and inhibition of carcinogen activation. (Lam et al., JNCI (2010) — PMID 20651274) Cauliflower contains glucosinolates (principally glucobrassicin and glucoraphanin) that generate isothiocyanates and indole-3-carbinol upon hydrolysis; these compounds inhibit phase I activating enzymes and induce phase II detoxifying enzymes, supporting chemoprevention and cellular longevity. (Manchali et al., Food Chemistry (2012) — PMID 22397945)

Synergies

Turmeric (synergy): Curcumin from turmeric and isothiocyanates from cauliflower synergistically inhibit NF-kB signaling, providing additive anti-inflammatory effects. - Extra-Virgin-Olive-Oil (complement): Olive oil increases fat-soluble carotenoid absorption from cauliflower and contributes polyphenols that act synergistically with glucosinolate metabolites. - Garlic (synergy): Garlic's allicin and cauliflower's isothiocyanates both activate Nrf2 through independent pathways, providing additive induction of antioxidant defense genes.

Flavor Profile

Taste: mild, slightly nutty when roasted, subtly sweet. Aroma: mild sulfurous (raw), nutty and caramelized (roasted). Texture: firm and crunchy (raw), tender (steamed), crispy (roasted). Category: cruciferous vegetable.

The Science

Lam et al., JNCI (2010) — PMID 20651274: Frequent consumption of cruciferous vegetables including cauliflower was associated with a statistically significant reduction in lung cancer risk (OR 0.72), attributed to isothiocyanate-mediated induction of phase II detoxification enzymes and inhibition of carcinogen activation. - Manchali et al., Food Chemistry (2012) — PMID 22397945: Cauliflower contains glucosinolates (principally glucobrassicin and glucoraphanin) that generate isothiocyanates and indole-3-carbinol upon hydrolysis; these compounds inhibit phase I activating enzymes and induce phase II detoxifying enzymes, supporting chemoprevention and cellular longevity. - Kaulmann & Bohn, Nutrition Research Reviews (2014) — PMID 24965336: Carotenoids and vitamin C from cruciferous vegetables including cauliflower work synergistically to reduce oxidative damage to DNA and lipids, with epidemiological evidence linking regular consumption to reduced incidence of cardiovascular disease and cancers — core longevity endpoints. - Book claim (medium confidence): Cauliflower is listed as a source of vitamin C (26 mg per 1/2 cup raw, ~43% DV).

Key Nutrients

Nutrient	Per 100g	Notes
Vitamin C	48.2 mg (raw)	Highly bioavailable when raw or lightly cooked; degrades rapidly with boiling (up to 50% loss). Maximize by steaming or roasting.
Glucosinolates	~25-60 mg (fresh)	Converted to bioactive isothiocyanates by myrosinase; cooking inactivates myrosinase but gut bacteria provide partial conversion.
Choline	45 mg	Well absorbed; important for membrane phospholipid synthesis, methyl-group metabolism, and acetylcholine synthesis (neurotransmitter); cauliflower is one of the better plant sources.
Folate	57 mcg	Natural food folate; ~50% bioavailability; supports DNA synthesis and repair processes central to healthy aging.
