Sulforaphane — The Bitter Sprout That Wakes Your Own Defences
Broccoli sprouts carry 10–100 times the glucoraphanin of mature broccoli, and when chewed it becomes sulforaphane — the most potent dietary activator known of NRF2, the master switch for the body's own antioxidant and detoxification enzymes.
How it works
Glucoraphanin is inert until the plant's enzyme myrosinase (released by chewing or chopping) converts it to sulforaphane; cooking destroys the enzyme, which is why raw sprouts, or a pinch of mustard-seed powder on cooked broccoli, matter. Sulforaphane then unlocks NRF2, raising glutathione and dozens of phase-2 enzymes for a day or more. Human trials are small but mechanism-rich: faster excretion of airborne-pollutant metabolites, modest glucose improvements in type 2 diabetes, and skin protection from UV in early work.
The practice
Half a cup of broccoli sprouts, raw and well chewed, three or four times a week — over salads, eggs, grain bowls. Grow them at home from tested seed with clean jars, or buy from a reputable grower. If it is cooked broccoli, add a pinch of mustard powder to bring the enzyme back.
The tradition
The bitter and pungent tastes — tikta and kaṭu — that Ayurveda insists every plate needs and modern plates have abandoned
Cautions
- ⚠ Sprouts can carry contamination — hygiene and source are everything.
- ⚠ Very high raw cruciferous intake with low iodine can burden the thyroid; moderate if that applies to you.
