But then, if you degree the antioxidant pastime of the leftover boiling water, the antioxidants weren’t destroyed, but just leached out into the cooking water. So, the researcher’s conclusion is that it’s “essential to devour the water used for boiling, similarly to the peppers, as bioactive compounds could be [left over] within the water.” But that’s now not the take-away i am getting from this study.

Drink the water or now not, pink peppers have nearly two times the antioxidant strength of inexperienced, irrespective of what you do.

I had in no way heard of steam blanching, however identical concept.

Steam for three mins, then cool off, which appears to be better, because you’re no longer immersing it in water.

Though, notice there’s now not tons distinction among steaming for six mins and steaming for 3, after which jogging underneath cold water. Too awful they didn’t observe roasting—that’s how you make cauliflower taste precise.

In fact, I’ve got recipes on roasted cauliflower in my How Not to Die Cooke book (for which all my proceeds go to charity, of route).

There are certain antioxidants we’re particularly interested in, though. Like the eyesight and mind-protecting inexperienced vegetable compound lutein.

Here’s the again of the eyeball.

Heat can definitely disrupt the mobile partitions, and all the little subcellular cubicles that may beautify the release of antioxidant compounds.

Sous vide become similar;

microwaving negative, as a minimum for the broccoli, and… steaming the movie star, almost doubling lutein tiers. Heat isn’t the best manner to liberate lutein from veggies.

And make a green smoothie, or pesto, or some sort of puréed spinach dish, and you may triple the bioavailability. But you need to watch the warmth.
