Dark Matter: The New Science of the Microbiome

Product Information

The “gut microbiome” is the name we have used to describe not only the wildly diverse collection of microbes that live there, but also what happens when they interact with each other and with our bodies. In other words, it’s an ecosystem made up of trillions of microbial life forms going about their business inside us, as we go about ours. In his new book Dark Matter: The New Science of the Microbiome, Dr James Kinross lays bare the mind-boggling world of what lies in our guts: the delicate ecosystem of trillions of microbial life forms that live within us all. Without us even realising, our gut’s unique ecosystem is the missing link in modern medicine and what’s more, is heavily influenced by our environment. A very small Italian study using a similar commercial probiotic, Sivomixx, piqued his interest after it suggested acute Covid patients treated with it might be less likely to end up in ICU or to die, and eight times less likely to suffer respiratory failure. Bjarnason is hoping to start a larger study in the next few months. We eat a lot of fermented foods in our house,” says Dr Kinross, who lives in London with his wife and two children. “We have a lot of kimchi and sourdough. We try to have a meal every day with some form of fermented food. Again, this is the whole microbiome argument. It improves the richness and diversity of the gut. We really like to do that.” Do eat 30 different fruits and vegetables a week The scale of the task is huge: there is 1.5kg of bacteria in our guts.’ Illustration: Lisa Sheehan/The Observer

Dark Matter by James Kinross | Waterstones

This book is really, really interesting ... Nothing more important in your life than your microbiome .... this will change your life Chris Evans In this mindblowing book, scientist and surgeon James Kinross explains how the organisms that live within us have helped us evolve, shaped our biology and defined the success of our species. But just as we have discovered this delicate and complex ecosystem within us, it is being irrevocably destroyed through antibiotic addition, industrial food production, the globalisation of our diets and lifestyles, and the destruction of our environment. Polyphenols are a naturally occurring antioxidant that helps produce good bacteria in the stomach. It also helps reduce inflammation in the gut. This magic chemical can be found in blueberries and vegetables such as aubergine, tomatoes, white potatoes and peppers. “It occurs in a lot of nightshade vegetables, so we have a lot of that,” he says. Kinross specialises in the detection of colon cancer and benign conditions of the gut. In his 18-year career, he has researched gut microbiome extensively and is the author of Dark Matter: The New Science of the Microbiome. He has learned that “lifestyle is overwhelmingly important for the gut”. While an FMT might be a new idea to many of us today, the medical practice of faecal transplant is ancient, and it has been drunk as “yellow soup” since the 4th century AD for the treatment of infective diarrhoea. In 1958 an innovative surgeon, Dr Ben Eiseman, administered faecal enemas to his patients in Denver, Colorado, with severe and recurrent C diff infections. It was remarkably effective, but like all important medical discoveries, this intervention was largely ignored at the time of its first report.What I particularly loved about this book is its strong scientific foundation. Kinross, a world-leading microbiome scientist and surgeon, offers a wealth of relevant insights drawn from his personal experience and over two decades in the field. The book serves as a much-needed, up-to-date summary of what is going on in this rapidly developing area of study. Tumeric, ginger, and other species are recommended but they’re not a panacea for a healthy gut,” says Dr Kinross. “We have to be quite careful when we’re talking about this. If you’re putting turmeric on fatty sausages, it’s not going to make any difference. Spices have to be part of a bigger nutritional strategy.” Don’t overuse antibiotics If you're a young parent, this book is particularly crucial for you. The gut microbiome plays a significant role in the health of young children, and Kinross provides actionable insights on what can be done to ensure better health for our children in the future. Instead, Dr Kinross recommends: “I would sit down with my doctor and ask, what medicines am I taking that I don’t really need to be on? You might be taking proton pump inhibitor medicines for changing the acidity of the gut, or any kind of unnecessary painkillers. Do I really need to be on medicines to control my blood lipid chemistry or are there things that I could change in my lifestyle that would reduce my blood cholesterol?”

In summary, "Dark Matter: The New Science of the Microbiome" is an enlightening and invaluable resource that I would highly recommend. Whether you're a health professional, a young parent, or simply someone interested in the future of healthcare, this book is a must-read. Dr Ben Mullish, a clinical scientist at Imperial College London, was running a trial of FMT in patients with C diff infections. Ray was so unwell that Dr Mullish offered him the treatment. Heather understood that there are good and bad bugs and advised her husband to go ahead with it, but Ray was not having it. The idea of taking another human’s faeces was just too much for him, and he refused. Three days later, however, he had deteriorated so much that there was no other choice. Ray consented to the trial. How well do you know your gut? You may have seen the word probiotics on your food, or possibly seen recipes to help your gut health with the three K’s: Kombucha, Kefir and Kimchi. But if your life depended on it, would you eat someone else’s poo? It’s also becoming clear that samples from some donors are much more effective than those from others. These are known as “super donors” and their faeces seems to contain a magical ingredient that makes it particularly effective. But we don’t understand why this happens, or whose poo will be most effective.

Yet it is only now, as we are beginning to discover the microbiome's enormous potential, that we are realising it is in grave danger, being irrevocably destroyed through the globalisation of our diets, the war on bugs and the industrialised world. More than half a century later, the Dutch gastro- enterologist Josbert Keller and his team at the Amsterdam Medical Centre randomised patients with recurrent C diff into three groups. The first group received vancomycin, a wash-out of the colon using a strong laxative, and a faecal transplant. The second had vancomycin and the colonic wash-out, and the third just received vancomycin. The FMT group did so much better than the other two groups that the study had to be stopped early, as it was deemed unethical to continue.

Gut health: The common mistakes everyone makes, and the

As someone with a PhD in Biotechnology, I can confidently say that "Dark Matter: The New Science of the Microbiome" by James Kinross is a fantastic read that I would highly recommend to anyone interested in health and well-being. I try to reduce the amount of meat that I eat. In fact, I almost never eat meat unless someone else is cooking,” he says. Instead, Dr Kinross focuses on eating a range of vegetables. “I try to have at least 30 different fruits and vegetables a week and I try to make sure that every meal I have is vegetable-based. We have a lot of salads in my house, and we love our polyphenols.” Some of these studies are extremely encouraging and offer treatments where few effective medical therapies exist. For example, FMT appears to be a promising treatment for irritable bowel syndrome and a recent study suggests that its benefit can last for many years: 125 patients were randomly assigned to receive either 30g or 60g of faeces from the same donor or a placebo transplant containing their own faeces. Researchers not only found that the FMT improved the symptoms, but there was a lasting benefit three years after it was given.

But what if I told you that faeces was not toxic waste and that it contained the secret to human health? Would you eat it, if your life depended on it? What if it was rebranded as a faecal microbiota transplant (FMT) or, more accurately, a faecal milkshake given through a tube that passes through the nose into the stomach? You could even take it in the form of a capsule – or “crapsule” – if you wanted.

James Kinross Can our microbiome save us? A ThinkIn with Dr James Kinross

But a healthy gut doesn’t just reduce the risk of cancer, it has wide-ranging benefits. “We have to think of the gut as this big sensory organ which has lots of lovely bacteria in it,” says Dr James Kinross, a consultant colorectal surgeon at Imperial College London. “That bacteria interacts with your environment, which then in turn communicates with your immune system.” Ray was readmitted to St Mary’s critically unwell and was soon diagnosed with Clostridium difficile (C diff) infection (officially, this bacteria has now been renamed Clostridiodes). A “hospital-acquired infection”, this disease is a complication of 20th-century medicine and an unintended consequence of Alexander Fleming’s discovery of penicillin, the first effective mass-produced antibiotic, in 1928. It is a global problem that afflicts 500,000 people in the United States each year and it kills 29,000 of them. Ray’s response to his FMT treatment was just like that in the reported literature. Within three days of receiving the microbiota transplant he was out of bed. Heather described it as a miracle. If I’ve spent longer than is entirely comfortable talking about faeces, that’s because FMT is a starting point for understanding the importance of the gut microbiome to human health. The extraordinary benefit of FMT in some patients has opened the clinical world to the idea that our microbes may have an important role in the causation and treatment of diseases where their involvement runs contrary to medical science.Though there’s still much about our microbiome we don’t understand, Dr Kinross highlights how learning about our microbiome has the potential to prevent illness, to shape how we think, how we feel and even who we choose as a partner. The human microbiome represents the most important new therapeutic target that we have for treating the greatest threats to human life in the 21st century and for preventing future pandemics of pathogens. This was not only important for Ray – it is critical for all of us: without a stable and diverse microbiome, we may well lose our minds. Behind all this is a simple message: microbes are not the enemy.
