What's That Rash? · Eat the rainbow: what can food colour tell us? · 15 Sep 2026 podcast

The skin of eggplant is part of that story as well.

Yes, you are.

Garlic, you're getting alicin, which has antiviral, antibacterial properties.

Some people believe that it's also protective against coronary heart disease.

You get potassium, you get fiber, you get B vitamins, so you get all sorts of benefits in terms of micronutrients from those as well.

And it's also healthy that you're not eating you you you always trade off in your food choices.

And if you're eating those vegetables rather than unhealthy proteins or unhealthy fats, then you're ahead.

Uh, I think that's right.

And that's partly because doctors get l really lousy nutrition education.

My nutrition education came from when I started becoming a health journalist rather than what I learned from medical school.

There was one medical researcher in Britain when I was training who didn't believe that cholesterol was dangerous, that it was that bad at times.

So I think that we have ignored the power of diet.

You know, and what what we haven't talked about are the kind of generic families that these compounds belong to, like flavonoids, polyphenols, alkaloids, terpenoids.

But it's all part of the defense mechanism of plants which benefit us in their diversity.

And diversity is the key here: that you're not throwing the dice on one particular food type or one particular family of.

of bioactive compounds.

And what I also want to talk about here is w we we said this at the beginning that we were deliberately going into this trap of talking about these individually.

But there's a lot of evidence that how you prepare your food, how you cook it, makes a difference to the effect of these drugs.

So you talked about turmeric.

So the active compound in there, one of them, is curcumin.
