You're about to listen to a BBC podcast and maybe it's when I had a hand in.

I'm Tammy Walker and I produce podcasts for the BBC.

My role is to give new and diverse creators a voice with the opportunity to build a career.

That's the thing I love about podcasts.

You start with just a good idea, but then you have the space to see where it goes.

And doing that at the BBC means we can really run with the best stories

while developing the most unique audio talent.

So if you like what you hear, why not check out the huge range of podcast we've got on BBC Sounds?

Hello, you're listening to Crowd Science from the BBC World Service and this week we're

coming to you from a festival in London, a vegan festival. The sun is out, people are having

a good time and feeling great.

But is that because of the lively atmosphere or because of their diet?

The WHO did find that red meat can put you at risk for cancer but I just find it a better

kind of energy source for me personally from my body. So I'm from Bahrain

so we're an island and there's a lot of fish there so usually

Piscatarian is the choice for a lot of people so it wasn't a hard transition for

me to cut red meat and then all weights. Do you think being vegan is a good thing?

Yeah, because it saves animals from being eaten.

Do you think being vegan is healthier or not healthier than you mean?

Healthier.

Because you're not eating animals.

Can live the healthy life being vegan.
