Hello, you're about to listen to a BBC podcast, and I'm Ed Gamble, host of another BBC podcast,

The Traitors Uncloaked. But my show is available only on BBC Sounds, just like Ellis and John's

Saturday bonus episodes, the Pop Top Ten podcast with Scott Mills and Ryland, and comedy specials

from the likes of Harriet Kemsley, Susie Ruffel and Rommas Shranger Nathan. However, and maybe I'm biased, it's really all about the traitors uncloked.

So for a whole bunch of exclusive scoops and podcasts, listen only on BBC Sounds.

BBC Sounds, music, radio podcasts.

Hello and welcome to the Inside Health Podcast with me, James Gallagher. You're even listening

Is it like wine tasting? Well swirl it but you don't need to spit. Okay. Yeah, that just tastes like sugar to me. Okay, that's really interesting. So that's actually saccharine and that was one of the first artificial sweeteners heavily used. Let's move on to this one. Okay. Okay, this is really weird. Is it different? I'm going for a second. I can't taste a thing.

Okay, that's a spartame and it's really interesting that you can sense the sweetness of saccharine but not a spartame.

I'm failing already, Sarah. Here we go. Give this one a stir.

This one's got a weird smell.

That, to me, that is so, did you put like a triple dose in that one?

Why is that?

So that's Stevie, and that's actually a natural sweetener, because it actually comes from a plant.

So it's actually not an artificial chemical like the others.

But it's really interesting that you say that that's sweeter than the others because all of these have different intensities. But when you actually buy them, they're actually
