If you’ve already read books like Martin Blaser’s Missing Microbes, a lot of this info won’t be new to you. However, Ed Yong’s enthusiasm and wider range — dipping into the microbes of other animals and even insects — is a joy. He also provides a counterpoint to some of Blaser’s more hysterical ideas about the loss of microbes. He agrees that microbes are important, and that our relationships with them are complex. But he doesn’t accept that we’re totally doomed. There’s tons of research into repopulating our guts with beneficial microbes, prebiotics and probiotics. No doubt things are in the pipeline which will make a difference.
Yong is significantly less hopeful about the potential of procedures like faecal transplants — though the results have been encouraging in cases of C. difficile infections, the potential for treating inflammatory bowel disease seems more limited. It’s not impossible that a refined version of faecal transplants can help to rebalance the irritated and inflamed gut systems of people who suffer from inflammatory bowel diseases… but so far, the data isn’t there.
With his enthusiasm and interest, Yong makes me want to hurry the heck up, get my biology degree, and get stuck into researching on exactly these topics. One thing is for sure: our microbiome is incredibly important, and we need more research. Our gut microbes can affect our overall health in so many ways — mental health included — that I foresee a lot more time being spent on this in labs in the near future. And I hope I’ll be one of the people working in one of those labs.
If you don’t know much about microbes, fear not: Yong’s writing is clear and accessible, with no technobabble. I think this book would be totally accessible to anyone with an interest.
