But you're actually outnumbered by even more bacterial cells.

但實際上你的數量比細菌細胞還要多。

And these little bacterial critters that air inside you are unique to you.

而這些在你體內空氣的細菌小動物，是你獨有的。

They're kind of like your own little bacterial fingerprints, and you can learn a lot about how these bacteria affect your life.

它們有點像你自己的小細菌指紋，你可以瞭解很多關於這些細菌如何影響你的生活。

By examining your poop, we found a company that actually examines your feces to tell you your gut health, and then we're going to take probiotics for 30 days and see if it can have an impact on our microbiome.

通過檢查你的大便，我們找到了一家公司，其實檢查你的大便就可以知道你的腸道健康狀況，然後我們要服用30天的益生菌，看看它能不能對我們的微生物組產生影響。

A little thing to put on the toilet, to poop on, to scoop a sample from.

一個小東西，放在馬桶上，用來拉屎，用來舀樣品。

And then we're good to go way that they make the shit looking this it's perfectly swirled like a soft ice cream.

然後我們就可以走了，他們讓這些東西看起來... ...就像一個軟冰激凌一樣完美地旋轉著。

Kind of just.

一種只是。

I don't know if that's gonna happen for me, but we'll find out gonna poop on that.

我不知道這是否會發生在我身上， 但我們會發現要去拉屎。

I'm not going to show you that part, and it's going to make its way into this tube.

我不給你看這部分，它要進入這個管子。

I'd like to think that we've been in a relationship for long enough that I could shit in front of you, but I don't know I'm a little nervous.

我想我們已經交往了很久，我可以在你面前拉屎，但我不知道我有點緊張。

I just don't think I'm ready to take that step.

我只是覺得我還沒準備好邁出那一步。

And based on my farts, it is definitely a biohazard.

而根據我的屁，這絕對是一種生物危害。

We pooped in all the appropriate places, Good on us.

我們在所有合適的地方拉了屎，很好。

It was a really challenging feet, and we did a great job.

這是一個真正具有挑戰性的腳，我們做了一個偉大的工作。

We also made some of our other friends do it as well to make our sample size bigger.

我們也讓其他一些朋友也這樣做，讓我們的樣本量變大。

And we wanted to talk to everyone and find out if off the bat anyone had some sort of digestion issues or concerns they might be thinking about with the bacteria in their bodies.

我們想和大家聊聊，看看是否有人一開始就有某種消化問題，或者擔心他們可能會考慮體內的細菌。

I did have EIB's.

我確實有EIB的。

It's a lot better now.

現在好多了。

Thankfully, I don't know that other people have the same problem, but I feel that I have a low tolerance for spiciness, both on the way in and on the way out to bloated.

還好，我不知道其他人也有同樣的問題，但我覺得自己對辣味的耐受力很低，無論是進食還是出食都很脹。

I feel bloated a lot, not a lot.

我覺得自己很臃腫，不是很多。

Sometimes, like I have a very sensitive stomach, a bit or whatever.

有時候，比如我的胃很敏感，有點什麼的。

It is not necessarily upset, but I like it, sings often.

不一定是不高興，但我喜歡，經常唱。

I don't really have a digestive issues, just like if I eat Popeye's like, yeah, I think my digestion is pretty normal.

我沒有真正的消化問題，就像我吃大力水手一樣，是的，我覺得我的消化很正常。

The first thing we wanted to analyze with our poop samples was how diverse our microbiome waas and the way that you look at diversity in someone's microbiome is was something called the Simpson's Diversity Index, with zero being no diversity that's bad and one being infinite diversity, which is actually impossible.

我們首先想用我們的大便樣本分析的是我們的微生物組的多樣性如何waas，你看一個人的微生物組的多樣性的方法是一個叫辛普森多樣性指數的東西，0是沒有多樣性是不好的，1是無限的多樣性，這其實是不可能的。

But 0.99 for example, would be a very diverse good number.

但以0.99為例，將是一個非常多樣化的好數字。

So looking at The Simpsons Diversity Index for your first sample, the score that you got with 0.72 0.750 point 820.850 point 850.88 you are above average.

所以從《辛普森一家》多元化指數來看，你的第一個樣本，你得到的分數是0.72 0.750分 820.850分 850.88你是高於平均水平的。

No, you mentioned that you did have I B s, which could be why your score is a little bit lower.

不，你提到你確實有I B s，這可能是為什麼你的分數有點低。

Diet is a huge when your diet throw your entire life.

飲食是一個巨大的當你的飲食扔你的整個生活。

Not just the day that you took your samples is really important.

不僅僅是你取樣的那一天，真的很重要。

I need to eat better, and I just don't.

我需要吃得更好，但我就是不吃。

So I'm not totally surprised.

所以我並不完全驚訝。

To be honest, I know this is a very small sample size, but it was really interesting to see that the people who had the most digestion issues also had the least diversity within their gut someone like Mitch, who had a lower diversity score.

說實話，我知道這是一個非常小的樣本量，但它真的很有趣，看到誰有最消化問題的人也有最少的多樣性內他們的腸道有人像米奇，誰有較低的多樣性得分。

Not all hope is lost.

並非所有的希望都消失了。

He can feed that good bacteria with prebiotic food and prebiotic food is hate to say it.

他可以用益生菌食品來餵養那些好的細菌，益生菌食品是恨不得說出來。

It's things like vegetables, leafy greens, artichokes, garlic.

就是蔬菜、綠葉菜、洋薊、大蒜這些東西。

Some things are delicious.

有些東西很好吃。

The more you eat, the more your bacteria eat and the more diverse your gut can become to snack on fruits.

吃的越多，細菌吃的越多，腸胃也會變得更加多樣化，可以吃零食水果。

I got my desk during the day, but then on the weekends I think I go like a little crazy.

我白天有我的辦公桌，但週末我覺得我像個小瘋子。

And mhm, I eat McDonalds lunch.

還有，我吃麥當勞的午餐。

I'll do like a protein and a vegetable and grain.

我會做喜歡的蛋白質和蔬菜和穀物。

Same thing for dinner.

晚飯也一樣。

In general, you have a pretty healthy microbiome.

一般來說，你的微生物組相當健康。

This can continue toe.

這可以繼續趾。

Nourish those bacteria by eating lots of prebiotic foods like garlic onions.

通過多吃大蒜洋蔥等益生菌食物來滋養這些細菌。

Eat so much garlic.

吃這麼多大蒜。

There you go, because I mean I'm gonna live longer, Not necessarily another way toe.

你去那裡，因為我的意思是我會活得更久， 不一定是另一種方式的腳趾。

Also help increase your microbiome.

也有助於增加你的微生物組。

Diversity is to take probiotics or eat probiotic food like yogurt or kefir.

多樣化就是服用益生菌或吃酸奶、酸奶等益生菌食品。

I don't know if that's how you pronounce it, but I think it is.

我不知道你是不是這樣發音，但我想是的。

So the next thing we did is we actually took probiotics for 30 days, and then we analyze our poop again.

所以接下來我們做的事情就是我們其實吃了30天的益生菌，然後我們再分析我們的大便。

Yes, we pooped in a cup twice.

是的，我們在杯子里拉了兩次屎。

We are champions.

我們是冠軍。

We wanted to see if those probiotics actually affected our microbiome and the diversity in our gut.

我們想看看這些益生菌是否真的影響了我們的微生物組和腸道的多樣性。

Initially, we saw that your diversity index was 0.72 and your second sample.

最初，我們看到你的多樣性指數是0.72，你的第二個樣本。

After taking probiotics, it was 0.738 point 74 So pretty much to say.

服用益生菌後，是0.738點74 所以說差不多了。

Okay, so then that means that the probiotics didn't have a major impact on like increasing the diversity or without looking at the exact species that increased in decrease.

好吧，那麼這意味著益生菌沒有一個主要的影響 就像增加多樣性或不看確切的物種，增加減少。

It's difficult to see if the probiotics really had an impact.

很難看出益生菌是否真的有影響。

However, there's so many other factors as well.

然而，還有這麼多其他因素。

So your diet throughout that time period, even your amount of sleep and exercise that you get impacts your microbiome diversity.

所以你在整個時間段的飲食，甚至你的睡眠和運動量都會影響你的微生物組多樣性。

It was 0.8.

它是0.8。

There was a little bit of a dip there.

那裡有一點兒凹陷。

But there's lots of factors that can affect your microbiome diversity.

但有很多因素會影響你的微生物組多樣性。

The sample might have been early in the week.

樣本可能是在本週初。

Maybe that weekend was rough.

也許那個週末很辛苦。

A rough weekend.

一個艱難的週末。

I don't know.

我不知道。

Your second sample your score was 0.91 whoa.

你的第二個樣本你的分數是0.91哇。

0.770 no.

0.770號

So there was a little quite a significant drop in your two samples.

所以你的兩個樣品有一點相當大的下降。

You want to say it was pop ized e?

你想說這是流行的嗎？

I'm like a two week bender.

我就像一個兩個星期的狂歡。

Oh, no, not definitely impact.

哦，不，不是絕對影響。

I remember to take the bills.

我記得要拿賬單。

What probably happened is, if you weren't eating very well over that time, period was probably with probiotics.

可能發生的情況是，如果你在那段時間吃的不是很好，期間可能是用了益生菌。

Probably weren't doing much for you.

可能對你沒有什麼用處。

They're probably just going in and out the other end.

他們可能只是在另一端進進出出。

Your second sample was Point eats it.

你的第二個樣本是點吃的。

Okay, so it went down a bit slightly lower.

好吧，所以就稍微低了一點。

Maybe it's cause I pizza the whole time.

也許是因為我一直在吃披薩的緣故吧。

It didn't need anything but pizza.

除了披薩，它不需要任何東西。

I hope not.

我希望不是。

There's no necessary dose for probiotics.

益生菌沒有必要的劑量。

Let's say you're taking three times the amount of probiotics, but you're not eating well, then the bacteria aren't going to colonize your gut.

比如說你服用了三倍的益生菌，但是你吃得不好，那麼細菌就不會在你的腸道里繁殖。

Anyway.

總之...

You have to get right.

你必須得到正確的。

You gotta get it right.

你得把它弄好。

We have now learned that you can't just go to the grocery store or pharmacy and buy probiotics and then expect that your microbiome is just gonna be all good.

我們現在已經瞭解到，你不能只是去雜貨店或藥店買益生菌，然後期望你的微生物組就是要去所有的好。

That's because many things affect your microbiome.

這是因為很多東西會影響你的微生物組。

For example, your health, your sleep, how much alcohol you take clearly, how much Popeye's you're eating clearly or things like whether or not you're vaginally birth or C section birth, it doesn't mean that probiotics are useless.

比如你的健康狀況，你的睡眠情況，你清楚地喝了多少酒，你清楚地吃了多少爆米花，或者你是不是陰道分娩或剖腹產等事情，並不意味著益生菌就沒有用了。

What it means is that if you're taking probiotics, you also need to be eating healthy, that prebiotic food that's gonna feed the bacteria.

這意味著，如果你在服用益生菌，你也需要吃健康的食物，那益生菌的食物會餵養細菌。

And just remembering that there's all different types of factors that will be affecting your microbiome so millennials you can't just drink a kombucha and assume everything's gonna be okay.

而只是記住，有各種不同類型的因素會影響你的微生物組，所以千禧一代你不能只喝昆布，並認為一切都會好起來。

There are way too many factors at play here and just get some good sleep.

這裡有太多的因素在起作用，好好睡一覺就好了。

Stop drinking booze and exercise.

戒酒，運動。

This is a new topic in science, and we're still learning a lot.

這是科學界的一個新課題，我們還在學習很多東西。

But what's important to know is that the trillions of bacteria within you do affect your brain and your body.

但要知道的是，你體內的萬億細菌確實會影響你的大腦和身體。

In fact, there are toilets that microbiologists are designing so that they will scan your poop and send your smartphone and analysis of your feces in order to tell you what to eat, how to be active and how to keep your microbiome healthy in the future.

事實上，有一些廁所，微生物學家正在設計，這樣他們會掃描你的大便，並將你的智能手機和分析你的糞便發送給你，以便告訴你未來應該吃什麼，如何活躍，以及如何保持你的微生物組健康。

After you take a dump or a poo poo instead of just flushing it away and not looking at it and pretending it didn't happen, we're gonna be wanting to dissect it.

在你拉屎或便便後，而不是一味地衝走，不看就當沒發生過，我們就會想去解剖它。

Get in there and find out more about our bodies.

進去了解一下我們的身體。

Okay, I'm done talking about poop.

好了，我不說大便了。

We can move on now.

我們可以繼續前進了。

Thank you so much for watching the company that helped us analyze our samples.

非常感謝你看了幫我們分析樣品的公司。

Was you about discovery?

你是為了發現嗎？

Go check them out in the description If you wanna do it yourself.

如果你想自己做的話，可以去描述中看看。

It's been a good day because we were able to contribute to scientific research on something we wish we could do every day.

今天是個好日子，因為我們能夠為科學研究做出貢獻，我們希望每天都能做一些事情。

Thanks for watching.

謝謝你的觀看。
