Publisher's Summary

In this groundbreaking book, Alanna Collen explores the extraordinary world of the powerful microbes that make up 90 percent of the human body.

You are just 10 percent human. For every one of the cells that make your body, there are nine impostor cells. You are not just flesh and blood, muscle and bone, brain and skin, but bacteria and fungi. You are not an individual but a colony of microbes. Far from being passive, the trillions of microbes that live on and in you are intimately involved in running your body. Even aspects that you think of entirely as ‘you' turn out to be run by ‘them' - like your immune system.

In this riveting, shocking, and beautifully written book, Alanna Collen explores the modern epidemics of ‘Western' diseases - obesity, autism, mental health problems, gut disorders, allergies, autoimmunity, and even cancer - and argues that most have their roots in our failure to cherish our most fundamental and enduring relationship: that with our personal colony of microbes. Antibiotics, antibacterial cleaners, rapidly changing diets, and our obsession with hygiene alter the microbe community we carry. Unlike our human cells, though, we can change our microbes for the better.

10% Human provides a revelatory guide to the role of your body's microbes in health and happiness. This is popular science at its most relevant: life - and your body - will never seem the same again.

To a hammer everything looks like a nail

Would you say that listening to this book was time well-spent? Why or why not?

The writer is obsessed with the microbes in the human gut, which are apparently responsible for everything from autism to acne. Gets a little wearying at times.

Were the concepts of this book easy to follow, or were they too technical?

Concepts well described if occasionally a little twee (or maybe that was just the reader - see below).

How did the narrator detract from the book?

100%. Amongst the many mispronunciations, she seems to believe that the word 'aitch' starts with the letter 'h', The accent grates from go to woe.

Do you think 10% Human: How Your Body's Microbes Hold the Key to Health and Happiness needs a follow-up book? Why or why not?

Maybe needs a book by someone who can provide counter-arguments.

Any additional comments?

Probably better read than listened to.

Outstanding and worthy of the highest praise !!

I've read dozens of very fine books regarding health and how our food choices affect us, but this book ranks at the very top in terms of the extraordinary depth it offers and the absolutely wonderful performance by the narrator. As I was reading it, I was unable to keep from telling all my closest friends that they should procure a copy, in particular those friends with young children or health issues such a IBS.
This book deserves a wide audience and hopefully it will get the recognition it deserves to make that happen autonomously.
Compliments to the author for her fine work.

Most interesting and informative book

One of the most informative books I've ever come across. I particularly liked the realistic scientific approach and avoidance of dogmatic statements found in many books relating to modern diseases and/or diet. Very easy to follow and grasp the concepts of this new field of science that exploration of microbiota has opened up. The very pleasant uk accent of the reader was just an additional cherry on top :-)

10% Human : Great Book.

A beautifully written book with a plot and a mystery waiting to be revealed. Yes I know it's a factual biological book but never the less this was a delightful listen which I found difficult to turn off.
It's so good to have English references rather than the American approach so many of these types of books are from the USA. This made it easier for me to hang on to the sometimes quite technical vocabulary.
I would definitely recommend 10%Human to anyone thinking of becoming pregnant as well as someone with a chronic condition or a lay person like me who is interested in long term good health.

Fascinating

Alanna Collen provides a detailed, easy to understand, science based account of her subject. This is the second book I have read on the subject and far and away the best. It is packed with information and provides a balanced view assuming a reasonable intelligence on the part of her audience and thus resists the tedious and somewhat patronising padding and self glorification of tomes written by self styled health gurus. Fascinating and sufficiently thought provoking to encourage further personal research and a second listen. Particularly recommended to those planning a family, suffering any kind of chronic or long term condition or recently recovering from a serious infection. Or indeed anyone wishing to avoid the latter two!

One of the most important books ever!

If you could sum up 10% Human: How Your Body's Microbes Hold the Key to Health and Happiness in three words, what would they be?

Just read it, you will not regret!

Any additional comments?

This book has changed the way I view myself, humans beings, medicine, food, disease, mental illness... pretty much everything! An incredibly well reasoned and researched body of work. Hope it is read far and wide.

Disappointing

What would have made 10% Human: How Your Body's Microbes Hold the Key to Health and Happiness better?

If the author had a larger grasp of her subject - she handles her material from a very partisan perspective of mainstream health-care and is somewhat disparaging of functional approaches without actually naming it; this unfortunately lends an uncomfortable bias to her book.

What was most disappointing about Alanna Collen’s story?

Her disparaging tone of anything about which she is insufficiently knowledgeable or cannot or has not been tested by mainstream healthcare.

What didn’t you like about Robyn Addison’s performance?

Her tone of delivery matches the tone of the book; "I know best and am negative about anything I disagree or am miss-informed about".

What character would you cut from 10% Human: How Your Body's Microbes Hold the Key to Health and Happiness?

This question is not applicable - I just would not recommend the book - there is value in some of what she has written but you can get this value in other, better books or from the internet.

Any additional comments?

Research the topic yourself and then read this and make up your own mind - but for a first introduction to the material I recommend looking elsewhere.

Life changing

my perspective on life is changed and I now have an appreciation of how complex and evolved our bodies are to depend on its microbes and that they must be at least protected if not cultured

WOW & THANKS Everyone should know this information

Would you recommend this audiobook to a friend? If so, why?

I recommend this book to every human who wants to understand and improve the short and long term health of themselves and their family.

Who was your favorite character and why?

The author for her sheer hard work and ruthlessness in uncovering all of the aspects that came together to paint the picture of the importance of our intestinal microbial friends and foes.

Which scene did you most enjoy?

Each example of how altering the microbial population of a human gut changed physical and mental disease states in humans back to normal health and function.

Did you have an emotional reaction to this book? Did it make you laugh or cry?

I'm a student of health and nutrition and consider myself to be very thorough. Alanna Collen has showed me that I am a novice in that respect. Her dedication and burning desire to uncover as much as we currently know about how our gut micro-biota plays a role in our health answered all of the questions, as best as science currently can, that have been formulating in my head for the last few years. I'm exhilarated that this book is available and so thankful to the author. I am incredibly inspired to offer this information to anyone else prepared to listen. And yes I laughed a few times in this book, mostly at the absurdity of current common thinking towards diet, medication and health in general. Boy have we got some things wrong up to now!

Any additional comments?

I wish that the author continues to apply her skills in the research and writings in the area of the microbial species symbiotic relationship with other animals including us humans! Yours sincerely, Timmy Adamson, Belfast NI

suitable to anyone that is into health

this book is great for anyone that wants to know more about their own body. what 21st century does to you. what is the microbiome and how to help your self to feel better. also I would advise this book especially for pregnant women and it has heaps of information how to help your self and the unborn child. although it can be hard to digest the information as there is a lot of scientific jargon.

10% on microbes 90% history

I felt really disappointed with the content as the title indicates the book is about microbes but actual fact it’s a general history and little about microbes themselves.
Wrong title for me as I expected a detailed write up about them. Instead a small personal history with little title content offered.

Enjoyable. I agreed with most of the content.

Where does 10% Human: How Your Body's Microbes Hold the Key to Health and Happiness rank among all the audiobooks you’ve listened to so far?

Apart from a couple of points which I think the author needs to update her research, overall the book was interesting, well read and enjoyable. Gives people a starting point to understanding chronic ill health.

What was one of the most memorable moments of 10% Human: How Your Body's Microbes Hold the Key to Health and Happiness?

The information about the difference in gut bacteria between skinny and fat people.

What about Robyn Addison’s performance did you like?

Easy to listen too. Speaks clearly

Really informative

Makes you think twice about whether or not you need that course of antibiotics. The other key take away was the lack of fibre in our western diet.

This book is a life changer.

The subjects in this book will lay the foundations to a revolution in eating, cleaning and health. Forget the Palio diet, live the Palio lifestyle for a longer healthier life.
Every single paragraph not only makes perfect sense , but it is backed up by sound science and research.

I'm telling everyone to read it.
