Hello, you're listening to CrowdScience 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,

転換語

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 meats can put you at risk for cancer, but I just

find it a better kind of energy source for me personally for my body.

So from Bahrain, so we're an island and there's a lot of fish there, so usually

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

for me to cut out red meat and then all meats.

Do you think being vegan is a good thing?

Yes, it saves animals from being eaten. Do you think being vegan is healthier or not

Do you think being vegan is healthier or not healthier?

Healthier, cause you're not eating animals.

You can live a healthy life being vegan and actually if you look back

through history, a lot of cultures especially like you know African cultures,

they consumed a lot of vegan food because meat is quite expensive.

The reason why we have headed out to this plant-based party is because this week

we've come to meet our listener in person. Hello Sam, how are you?

Yeah it's a really sweltering day in London and you brought us to a festival, a vegan festival in

east London. The Sun is just going down there's lots of people drinking, having a

Because I have a question for you: is being vegan better for your health?

So why do you want to know the answer to that question? Are you vegan?

No I'm not. I guess that's why I'm asking because I'm,

I've been moving towards a vegan diet but haven't quite got there. Answering this

Help you decide okay. So Sam wants to know whether

it's healthier to cut out all meat and animal products from her diet. The people

at the vegan festival would certainly say it is but what does the evidence say?

Does sticking to plants make you live longer? is it better for your heart or

your immune system? And are you less likely to get certain diseases? There's a

lot of information out there about the health impacts - good and bad - of a vegan

diet. So CrowdScience is here to trawl through the facts and figures for you.

To start things off with me here in the studio is producer Caroline, hello Caroline!

Hello I'm good how are you? I'm very well. So Caroline you are a vegan.

I am. Well I'd call myself plant-based.  Okay, what's the difference?

well it basically gives me wiggle room when I mess up and eat cheese. I can be like, oh I'm only

plant-based, I'm not vegan!  Okay so most of what you eat comes from plants but

occasionally you might eat dairy products or something like that.

Yeah, basically I'll eat dairy if i'm at someone's house and they've cooked for

me. I don't be annoying and be like, no I won't eat that.

Or it if you're a bit sad or happy... ... or I'm feeling a bit down, or want a reason to celebrate..

Or if I'm a bit hungry or a Tuesday (laughing). Okay cool and so are you mostly a vegan then for health reasons?

No not for health reasons for environmental reasons and animal welfare reasons.

For years now, yeah for years. I've been veggie most of my life and basically...

So you've grown up as a vegetarian?  So I wanted to be vegetarian pretty much as

soon as I realised that meat was animals, but my mum was really worried that I

wasn't going to get enough protein, so she used to hide meat in my food, so that

is how worried she was for my health.  Okay and I mean does she still do that if you

go round for dinner?  I mean I hope not who knows? But no she doesn't. She actually

doesn't know that I'm vegan because I know that she'll worry. So when I go

around for dinner I just kind of pick out the vegetables and look really rude

and like I don't eat much. But like surely your mum would understand now

because veganism is really common. I mean you only have to walk out of the office

and there's like about three new vegan food chains before we came to the studio.

I had a look online - so the number of vegans in America grew from 4 million in

2014 to nearly 20 million in 2017. And here in the UK,

nearly half of vegans cite health as one of their reasons for their food choices.

So there are obviously lots of other reasons for deciding to be a vegan:

environmental reasons animal welfare considerations. We're not going to get

into that on this show. We are going to focus on the health impacts. Yes but if

any one listening does have questions about any of those other reasons, then do

send them in because maybe we can look into it in the future. So Anand - last time

we worked together we made a programme about motivation and I signed you up for

a 200 metre open water swim.  Yeah proudest achievement probably so far

clocked up on CrowdScience.  So what do you think your challenge is going to be this week?

I mean I'm gonna take a punt and say that I have to become vegan for

the rest of my life or something ridiculous like that.

Not quite the rest of your life, just two weeks. Will you do it? I guess, yeah, I

don't really have a choice! Okay so two weeks sounds manageable. I'm a little bit

wary because I do enjoy cheese and butter and eggs and honey - all the things

that you're not allowed to eat on a vegan diet. I suppose I would be a bit

worried about potentially getting enough of everything.

Okay well don't worry we're going to get all the information in this programme to

make sure you're doing it properly and to make it easy I've arranged for your

first meal to be a bit of a treat. So you're going to go for a burger at a

vegan restaurant around the corner called Eat By Chloe to meet CrowdScience

friend and nutrition expert Dr Giles Yeo who's going to give you some tips on how to adjust to the diet.

So I think our food is here. That looks like a

burger and that definitely looks like a sub. Giles, can I get you any ketchup? Or aioli? Oh yes,

ketchup and aioli. It's terrible, oh my god, if my wife... actually she might

be listening. She thinks that I murder food because I like a little bit of food

with my ketchup. And aioli. This is a pesto meatball. I'm gonna - I'm gonna take

a bite all right. First impressions.  Sorry? Haha

The thing is I went for the sub because meatballs, pretty much, it's meat that's

been completely blitzed up and it's actually quite suitable for for the

vegan treatment. It's easy, it is very, it's very easy to get a texture and then

when you put it in something like the meatball sub it's all about the sauce, you can cover it up.

It's very good! Okay, I'm gonna go in for my "bacon cheeseburger" so there

are some little bits of - where's the bacon? - I don't know it's... maybe these

little brown shavings? There's pickles which is good. Okay I

think for the purposes of radio, I'm gonna need to take another bite. For sure.

So in terms of the nutrients that you need to get in a diet and the things

that you might be wary of missing out on if you become vegan, you have to watch

out when you're being vegan and there are few things you have to replace, okay

So let's start with the things you gotta watch out. You have to make sure that you

get a full range of the type of protein that you're actually gonna need. The

proteins are put together by these things called amino acids and not all
