Dr. Kevin Tracey is a pioneer in understanding the molecular basis of inflammation, and identifying the way in which neurons control the immune system via the Vagus Nerve. A neurosurgeon, scientist and entrepreneur, he is CEO of Feinstein Institutes, New York, where they bridge neuroscience, molecular biology and biomedical engineering. His lab’s discoveries led to the first clinical trials in neuromodulating devices paving the way for a new field, termed bioelectronic medicine.
In his new book “The Great Nerve, the new science of the Vagus Nerve and how to harness its healing reflexes” he has distilled his research to try and make complex science accessible so that those of us without medical degrees are able to sort the fact from the fiction when it comes to the, much-discussed, Vagus Nerve. In this week’s episode Dr Tracey sits down with Emily Kate Stephens to discuss his expansive work and how he believes that this could be a tipping point in our management and treatment of a wide range of diseases.
He explains the role of the Vagus Nerve, a highly complex superhighway carrying messages between the body and the brain, which controls the reflexes of organ function to maintain the body in homeostasis and balance the sympathetic and parasympathetic nervous systems. Understanding this, previously unmapped, connection between the body’s and the brain’s networks has huge implications for treating inflammatory conditions from rheumatoid arthritis to depression, with millions of patients already being treated with implanted neuromodulating devices.
But, he also highlights the need for maintaining the highest scientific rigour and continuing to research why such treatment is effective in some patients and not all. He points to the need for larger clinical trials to understand the effectiveness of vagal nerve stimulation (VNS) in implanted devices and particularly in the less-regulated ear-based devices. He wants to arm patients with the information to enable them to self-advocate and explore the possibilities of using the healing power of the Vagus Nerve to replace anti-inflammatory drugs, with the potential to slow disease progression and accelerate healing.

Ruthie's Table 4
For more than 30 years The River Cafe in London, has been the home-from-home of artists, architects, designers, actors, collectors, writers, activists, and politicians. Michael Caine, Glenn Close, JJ Abrams, Steve McQueen, Victoria and David Beckham, and Lily Allen, are just some of the people who love to call The River Cafe home. On River Cafe Table 4, Rogers sits down with her customers—who have become friends—to talk about food memories. Table 4 explores how food impacts every aspect of our lives. “Foods is politics, food is cultural, food is how you express love, food is about your heritage, it defines who you and who you want to be,” says Rogers. Each week, Rogers invites her guest to reminisce about family suppers and first dates, what they cook, how they eat when performing, the restaurants they choose, and what food they seek when they need comfort. And to punctuate each episode of Table 4, guests such as Ralph Fiennes, Emily Blunt, and Alfonso Cuarón, read their favourite recipe from one of the best-selling River Cafe cookbooks. Table 4 itself, is situated near The River Cafe’s open kitchen, close to the bright pink wood-fired oven and next to the glossy yellow pass, where Ruthie oversees the restaurant. You are invited to take a seat at this intimate table and join the conversation.
