Broccoli has a clever little chemistry trick, and the result is a bioactive plant compound called sulforaphane 🥦
Chances are you’ve never heard of it before, but here’s what you need to know.
Broccoli doesn’t simply sit there full of ready-made sulforaphane.
Instead, broccoli contains a precursor called glucoraphanin and an enzyme called myrosinase. These are stored separately within the plant. When we chop, grate or chew raw broccoli, its cells are damaged, bringing the two together and allowing sulforaphane to form.
Sulforaphane is attracting plenty of research interest for its potential role in supporting the body’s antioxidant defences, inflammatory pathways and natural cellular protection systems.
The research is promising, but still developing, particularly when it comes to meaningful long-term health outcomes in humans. So this isn’t a claim that broccoli prevents or cures disease, and it certainly doesn’t need to become another expensive “superfood” supplement.
It’s simply one more fascinating reason to include cruciferous vegetables regularly.
Heat can reduce the activity of myrosinase, which makes raw broccoli a particularly interesting way to eat it. And this raw broccoli salad is easily my favourite way to do that. Finely chopped, crunchy and far more enjoyable than eating plain raw florets!
Cooked broccoli is still an incredibly nutritious food, too. This isn’t about choosing the “perfect” preparation method, it’s about adding variety and finding ways of eating vegetables that you genuinely enjoy.
Would you eat broccoli raw? 🥦
