Transcript: English Fluency Lesson: You Think All Bacteria Are Bad? Think Again

Understanding your microbiome and why that's worthwhile

Hi there, and welcome to this podcast. Here's a two kilogram bag of cat food. You'll understand why that's relevant in a minute.

Did you ever think that the secret to managing your weight, improving your level of happiness and even fighting off diseases may not lie in your gym membership or in the medicines that you take?

But instead in the bacteria that live in your gut! Bacteria, B A C T E R I A means 'your microbes'. And your gut, G U T is where you digest your food. And Yes, you heard that right? Your gut bacteria massively affect your health. Stick around and we'll get into this fascinating topic that's challenging the way we think about health and wellness.

In this podcast, you'll uncover amazing facts about your microbiome, learn practical ways to improve your health, while at the same time enriching your English vocabulary and improving your English comprehension!

This podcast is a unique combination of 'health wisdom', and language learning, made especially for you.

And did you know that your gut health could be influencing your ability to learn? Listen to the end of this podcast for a surprising connection between what's happening in your gut and what's happening in your brain, as well as some tips on how to help your gut bacteria.

Hello, Iโ€™m Hilary, and youโ€™re listening to Adept English. We will help you to speak English fluently. All you have to do is listen. So start listening now and find out how it works.

Understanding what your microbiome is

So, have you heard of that word 'microbiome'? That's M I C R O B I O M E. 'Microbiome'. Even if you don't have pets, even if you don't like animals, did you know that you are the host to a variety of species, species of bacteria living inside you!

So your microbiome refers to the community of bacteria, B A C T E R I A, which live inside you, specifically in your gut, G U T. Your 'gut' means 'your digestive system where you digest your food'. That's 'to digest', D I G E S T. It's what we do with our food and mostly that happens in our intestines, I N T E S T I N E S, 'intestines'.

Until a few years ago, probably most of us would've thought of bacteria as a bad thing. Bacteria might get into our food and make us ill, or bacteria might get into a wound in your finger, make it go hot and red and possibly septic. S E P T I C. Quite a lot of body and health words today, you'll notice!

And in the UK we use a lot of antibacterial sprays and wipes. We like to think that the place is clean, especially in our kitchens and our bathrooms. But for the last 10 or 15 years, we've been made aware of the benefits, the idea of 'beneficial' bacteria. ' Beneficial', B E N E F I C I A L is an adjective. And here it means 'bacteria which help us, bacteria which benefit us, do us good'. That's 'beneficial'.

2kg of bacteria!

Did you know that in your gut, your intestines, it's estimated that there are trillions of bacteria? ' Trillions', T R I L L I O N S. A 'trillion' is a big number. It's a one with 12 zeros behind it. A trillion. That's a lot of bacteria. And the bacteria living in your gut could weigh as much as two kilograms. This bag of cat food again, actually, yes, that's quite heavy. Two kilos of bacteria. Imagine that!

Without these bacteria, we would be unable to digest our food and it would make us ill not to have them. And there are people who are lacking in gut bacteria. It does make them quite seriously ill sometimes.

And what's really interesting? The mix, the community, the population of bacteria living in your gut - it's like any big city in the world - the population can be very different from person to person. Gut bacteria, very enormously from person to person.

And which gut bacteria we have can massively determine our health.

Could your gut microbiome be the key to a higher quality of life?

Of course, this is something that we can influence. More of that in a minute. But did you realise that gut bacteria also have an important role to play in our mental health?

So there's believed to be an effect of gut bacteria on your brain and your mind and your mood. Your mood, M O O D. That's the word we use in English to talk about how happy or how sad we feel.

One large scale study, which involved over a thousand participants, found that certain gut bacteria were associated with a higher quality of life. It's THAT important! And there were fewer of these 'good gut bacteria' in people who had depression and low mood. So there's a potential link between your gut biome and your mental health.

Your gut bacteria also affect your weight. That's W E I G H T, how many pounds or kilos you weigh. Lots of people struggle with their weight, so this is worth knowing. And being overweight can lead to other health problems as well.

Also important, your gut bacteria play a huge role in your immune system. Your immune system? That's I M M U N E. That's the system in your body, which helps you fight off diseases and illnesses. Your 'resistance' to disease, if you like. So what diseases you get is somewhat determined by your gut bacteria. They're really important then, aren't they?

And that's just what scientists know so far from studying gut bacteria. A lot is still waiting to be discovered. It's a fairly new area of study.

"The microbiome is the most important discovery for human healthcare in recent decades"

A quotation so that you can practise slightly more difficult English? James Kinross, a surgeon and microbiome scientist at Imperial College London says,

"The gut microbiome is the most important scientific discovery for human healthcare in recent decades. We discovered it or rediscovered it in the age of genetic sequencing less than 15 years ago. We don't really know how it works. And at the risk of sounding like the late Donald Rumsfeld," he's making a joke here, "There's what we know, what we think we know, and an awful lot that we don't yet have a clue about."

So the scientists are clearly still learning about gut bacteria and the microbiome. But what is certain is that it determines our short-term and our long-term health.

Early influences on your microbiome

A really interesting fact for you. If as a baby you were born naturally, meaning that your mother gave birth naturally to you, you will have inherited a whole lot of bacteria from your mother. Beneficial gut bacteria.

If you were born as a 'Caesarian Section' or C-section baby, this won't have happened. A 'C-section' is where the mother has to have surgery in order to deliver the baby. And a study in 2019 showed that there is an effect, a difference here, even later in life. People who were born as C-section babies were more likely to have certain health problems later on. So it's quite a long lasting effect.

When you're a newborn baby, another situation that makes a difference whether or not you're breastfed. So breastfeeding also helps the baby's microbiome develop properly.

How can we help our microbiome now?

So while the mysteries of the microbiome and the gut bacteria are still being discovered, what can we do to help ourselves? One of the measures of gut bacterial health, how long does it take for our food to pass through us?

Studies have been done to test this, where people eat food with dye, D Y E in it. A 'dye' gives a particular colour.

The longer it takes for your food to pass through you, the less healthy is your gut, it seems. If it takes over 24 hours, that means 'less healthy', under 24 hours 'more healthy'. But I think each of us probably have a sense of whether or not things are well in that department.

Pre- and Probiotics

So what things can you do to help your microbiome, your gut bacteria?

Well, of course there are lots of products you can buy, which are supposed to help. ' Prebiotics', that's P R E B I O T I C S. And 'probiotics', P R O B I O T I C S. What do they do and what difference do they make?

Well, 'prebiotics' are intended as food for your gut bacteria. You eat the prebiotic, but it passes straight through you and goes to your gut bacteria and feeds them.

And a probiotic? This is something that you take that aims to introduce more of those beneficial bacteria to your gut. So it's something you take, which contains bacteria. Hopefully they'll make it into your gut and start living there, set up their homes there inside of you.

So the idea is that you can introduce those beneficial bacteria that you are lacking. Pre and probiotics, it's a big industry and not all of them work. So do your research before buying these products. Some are good, some less so.

What you eat fundamentally transforms your gut microbiome

The best way to influence your gut bacteria in the right direction? It's simply through your food, through what you eat. One of the things I've done recently - stopping eating refined sugars altogether. The only sugar I eat is in fruit. No cakes, no biscuits, no sweets. Only fruit.

And it's made a massive difference to me. I can feel the difference, and this is because refined sugar kills off your gut bacteria. What's also quite damaging to your gut bacteria, all those artificial sweeteners, so low calorie drinks. Artificial sweeteners are added to things to make them sweeter without it being sugar. They're just as bad apparently.

And if you've had antibiotics, well the clue is in the name, I guess. Antibiotic medication will also kill off your good gut bacteria. So if you've had to have antibiotics recently, it's worth thinking about how to help your microbiome get back to normal.

The advice about your microbiome usually focuses on having enough 'fibre' that's F I B R E in your diet. That's what comes largely from eating fruit and vegetables.

Listening Lessons

Junk food and ultra processed food

Another thing to think of though here is 'ultra processed foods'. The more processed a food is, the further away it is from the original food source, the less good it is for us to eat. And ultra processed foods are particularly bad. They usually have a long ingredients list full of chemicals, which you don't recognise from your kitchen cupboard.

Ultra processed foods are a long way away from the original food form. You're much better cooking, starting with natural, recognisable food ingredients.

Download The Podcast Audio & Transcript

Junk food. J U N K is ultra processed food. It's fine to enjoy as a treat, but you are really harming yourself if you eat it every day and you are harming all those lovely beneficial bacteria in your gut. It's much better to do what we call in English 'cooking from scratch', where you start off with recognisable food, ingredients. Fruit, vegetables, meat, fish, oil. Eating like this most of the time will make a huge difference to your gut bacteria, to the health of your microbiome.

How else can we maintain a healthy microbiome? By making sure that we get good sleep? Are you ready to make some changes in your lifestyle for your health?

Further Research

One of the people in the UK who is studying all of this, Tim Spector. He's done a massive amount of work on this and it's really interesting. And he's still going with his Zoe program in the UK. Many fascinating facts are coming out of his work.


If you'd like to know more about this, let me know and I'll do some more podcasts on it.

Enough for now. Have a lovely day. Speak to you again soon. Goodbye.
