10% Human How Your Body's Microbes Hold the Key to Health and Happiness

10% Human How Your Body's Microbes Hold the Key to Health and Happiness

Author: Alanna Collen Format: Hardback Release Date: 23/04/2015

You are just 10% 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, auto-immunity, and even cancer - and argues that most have their root 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.

Author: Alanna Collen Format: eBook Release Date: 01/03/2018

You are just 10% human. For every one of the cells that make up the vessel that you call your body, there are nine impostor cells hitching a ride. You are not just flesh and blood, muscle and bone, brain and skin, but also bacteria and fungi. Over your lifetime, you will carry the equivalent weight of five African elephants in microbes. You are not an individual but a colony. Until recently, we had thought our microbes hardly mattered, but science is revealing a different story, one in which microbes run our bodies; remaining a healthy human is impossible without them. In this riveting, shocking, and beautifully written book, biologist Alanna Collen draws on the latest scientific research to show how our personal colony of microbes influences our weight, immune system, mental health, and even our choice of partner. She argues that so many of our modern diseases-obesity, autism, mental illness, digestive disorders, allergies, autoimmune afflictions, and even cancer-have their root in our failure to cherish our most fundamental and enduring relationship: that with our individual colony of microbes. The good news is that unlike our human cells, we can change our microbes for the better. Life-and your body-will never seem the same again.

Obesity, autism, mental health problems, IBS, allergies, auto-immunity, cancer. Does the answer to the modern epidemic of `Western' diseases lie in our gut? You are 10% human. For every one of your cells, there are nine impostors hitching a ride. You are not just flesh and bone, but also bacteria and fungi. And you are more `them' than you are `you'. Your gut alone hosts 100 trillion of them and until recently we thought that our microbes didn't matter. This is all set to change as the latest scientific research tells a very different story, one where microbes run our bodies and becoming healthy is impossible without them. In this ground-breaking book, biologist Alanna Collen reveals how our personal colony of microbes influence our weight, immune system, mental health and even our choice of partner. This is a new way of understanding modern diseases - obesity, autism, mental health problems, gut disorders, allergies, auto-immunity and even cancer - as she argues they have their root in our failure to cherish our most fundamental and enduring relationship: that with our microbes. Illuminating many of the questions still unanswered by the human genome project 10% Human completely changes our understanding of diet, modern disease and medicine. The good news is that unlike our human cells, we can change our microbes for the better and this book shows you how. A revelatory and indispensable guide: life - and your body - will never seem the same again.
