As a human being, you are not a single organism but a thriving ecosystem home to trillions of invisible, living microbes. These microbial jungles within you and upon you are critical for your health and survival and may influence everything from your risk of cancer to your sexual attractiveness. In this podcast series (Biomes), Dr. Ruairi Robertson explores the fascinating new developments in our understanding of the human microbiome and talks to leading scientific experts around the world about the incredible ways microbes affect your body, from belly to brain.

    Artificial sweeteners and the gut microbiome | Dr. Jotham Suez | Season 3, Ep. 2

    Artificial sweeteners and the gut microbiome | Dr. Jotham Suez | Season 3, Ep. 2

    Increasingly, dietary sugar is being replaced by non-caloric sweeteners in our diets. But what effects do these sweeteners have on our health? Only last year, the World Health Organisation categorized the sweetener aspartame as "possibly carcinogenic to humans", yet lots of evidence suggest that sweeteners are beneficial for weight loss and blood sugar control if they replace high sugar intakes. In this episode, I speak with Dr. Jotham Suez who has conducted some ground-breaking research on the effect of non-caloric sweeteners on the gut microbiome and the potential detrimental effects this may have on metabolic health.

    Season 2, Ep. 6: Infection Biomes | Prof. Brett Finlay

    Season 2, Ep. 6: Infection Biomes | Prof. Brett Finlay

    Infectious diseases have largely been replaced by chronic diseases such as diabetes, heart disease and cancer in the Western world. However, the COVID-19 pandemic has shown us that humans are still at significant risk from microbial-diseases. In this episode, Dr. Ruairi Robertson speaks with Prof. Brett Finlay from University of British Columbia, one of the world’s leading experts on infectious diseases. Prof. Finlay discusses his career studying infectious microbes and how this led him to shift focus to all of the other microbes in our body. He discusses the influence of the gut microbiome on infection susceptibility, fulfilling Koch’s postulates for the gut microbiome and the influence of early life gut microbes on ‘modern plagues’ such as asthma and allergies.
     
    Prof. Finlay is one of the scientific co-founders of Microbiome Insights along with Dr. Bill Mohn. Between them, they have published more than 600 peer reviewed papers and they provide key scientific guidance to the Microbiome Insights team. Find out more at  www.microbiomeinsights.com.

    Season 2, Ep. 5: Fungal Biomes | Prof. Marie Claire Arrieta

    Season 2, Ep. 5: Fungal Biomes | Prof. Marie Claire Arrieta

    When you hear the phrase ‘gut microbiome’, you most often think about bacteria. However, a huge proportion of your intestinal microbes are viruses, archaea and fungi. These other microbes however, have been studied in much less detail and we know less about what they are doing to your body. In this episode, Dr. Ruairi Robertson speaks with Dr. Marie Claire Arrietta from University of Calgary, a leading researcher on fungal microbiomes. She discusses how gut fungi interact with the immune system, myths about Candida and how gut fungi may affect children’s lung health.
     
    Microbiome Insights provide services to assess the fungal microbiome using ITS2 sequencing. Find out more at www.microbiomeinsights.com

    Season 2, Ep. 4: Cancer Biomes | Prof. Wendy Garrett

    Colorectal cancer is one of the most common cancers and cancer deaths worldwide and its rates are increasing in many countries around the world, especially in younger adults. Emerging evidence points to a role of certain gut microbes in the progression of colorectal cancer by acting as toxins to gut cells. On the other hand, other microbes have been identified as potentially protective against colorectal cancer. In this episode of Biomes, Dr. Ruairi Robertson speaks with Prof. Wendy Garrett of Harvard University. Prof. Garrett is a leading doctor and researcher in the field of the colorectal cancer and the gut microbiome. Her work has shown exciting links between microbes originating in the mouth and how they may contribute to cancer when they travel down to the gut. Prof. Garrett discusses this research and future potential of targeting the gut microbiome as an adjunctive therapy for colorectal cancer.

    Season 2, Ep. 3: Fermented Food Biomes | Prof. Paul Cotter

    Season 2, Ep. 3: Fermented Food Biomes | Prof. Paul Cotter

    Kombucha, kefir, sauerkraut, kimchi… fermented foods such as these have suddenly appeared on the shelves and menus around the world. Much of this is due to our increasing knowledge about our gut microbiomes. But what is the scientific evidence behind fermented foods? Do they actually change our gut microbiomes? Do their microbes survive transit through the gastrointestinal tract? Should we all be eating more fermented foods? In this episode, Dr. Ruairi Robertson speaks to Prof. Paul Cotter from Teagasc Food Research Centre and University College Cork in Ireland to answer all of these questions and discuss his world-leading research in fermented foods.
