Gut: A Review

Book Review

It is my gut feeling that few of us think that our gut feeling is as important as what our heads or hearts feel. Classically they conflict, we should follow our heads or our hearts, but you really really should trust your gut.

Giulia Enders weaves a funny and informative narrative about all things to do with our largest organ, I must insist you STOP WHAT YOU ARE DOING, go buy this book…

Available at your local, independent or commercial bookshop or online various, including: Gut: The Inside Story of Our Body’s Most Underrated Organ 

… AND READ IT STRAIGHT AWAY.

Now that you’ve read it, I don’t need to review it and I am sure you will agree that you have learned more about your body in those ~250 pages than you have since school.

In case you didn’t read it (why not?! I thought the above prose was pretty damn convincing), I will put down a few things here that I hope will make you want to read it.

Firstly, this book is so easy to read, it is a joy to learn about how you should be pooing (yes, you’ve been doing it wrong all these years), about how your gut thinks independently of your brain and the illustrations are just so quaint, yet highly informative!

Secondly, despite having a gut feeling for millennia, it is literally in the past decade (and even then, barely that long) that science is finally waking up to the idea that our gut actually has something to say and we should be damn well listening!

Only someone as passionate about poo as Giulia can make you give a shit about yours.

Did you know that babies in the womb are totally sterile!? As soon as they enter the birth canal or are born by caesarean section, they start acquiring the microbes that will shape their gut flora for the rest of their lives.

There is a brain/gut link, though the gut can do it’s own thinking, sometimes it has to demand that the brain listen (and vice versa). This includes times of stress (and hence, stress-related gut pains/stomach ulcers/constipation etc…), otherwise the gut just gets on with things without us realising as it is made of unconsciously controlled ‘smooth muscle’.

Furthermore, our gut flora (the many billions, trillions? of microbes that live in our gut and on average contribute 2 kg to our overall weight) can also affect our mood, with links to depression and anxiety. Simply (not simply) – happy gut, happy brain – the link between the gut, diet (and hygiene, i.e. contact with bad bacteria), and hence our gut flora, and depression is becoming clearer with each new study.

A healthy gut flora (good bacteria) leaves less and less room for any bad bacteria that we may encounter to latch on and make us feel unwell.

How’s your poo looking? Check out the Bristol Stool Scale to check how you are doing. For info on how to achieve the perfect poo, get this book!

Tend to your gut garden and introduce good flora such as Lactobacillus acidophilusLactobacillus rhamnosus and Lactobacillus casei Shirota by eating natural yogurts or yogurt drinks that contain live cultures. (A favourite breakfast of mine: cornflakes/muesli (~15g), flaked almonds and/or seed mix (~10g) and natural yogurt (~100g) with a sprinkle of cinnamon (total: ~225 kcal).)

Ever wondered why being unwell can be made so much worse by an unfortunate “shart”? Or why long distance runners “shouldn’t trust a fart after X miles of running”? I’ll let Giulia explain at her award winning Science Slam talk, where only someone as passionate about poo as her can make you give a shit about yours. Get talking about your gut and you’ll realise that “the anus [and this review] is only the tip of the iceberg”.
