And hedonia.

I have never heard of that word.

Could you explain what that means?

Okay.

Have you heard of it, Jonathan?

Now, in your book, you reveal that there's five ways that we can tackle high functioning depression.

Could you talk us through those?

And could that be just even acknowledging it to yourself?

You might not yet be ready to acknowledge it externally.

I think we've got like a month's worth of dinners for our win.

No, Zoe's very good actually, I think.

And not just the big ones.

I love that, the small wins, because it's the small wins that I don't think we acknowledge, but it's the things that are occurring hour after hour, day after day that are challenging.

So I think there's no specific way of eating that would be different to what we would recommend for everyone, you know, specifically for mood.

So we would recommend for everyone's physical and also mental health to be following the kind of diet we encourage at ZOE.

So this is a diet rich with whole foods, whole plant-based foods, lots of colour, as your dad told you, Judith.

So a diversity of different plant-based foods that are rich in color because they contain all of these magical chemicals called polyphenols, which we know act on anti-inflammatory pathways.

Lots of fiber-rich foods, so whole grains, legumes, pulses.

Foods that also contain omega-3, and Judith touched on this as well.

Omega-3 is a particular kind of fat.
