Inflammation is the body's response to injury and foreign microbes. But as our environments and diets have changed, low-level inflammation, simmering quietly and undetected, has been identified behind everything from heart disease and cancer to mysterious autoimmune conditions. Shilpa Ravella is a doctor at the forefront of this field, specialising in gut transplants, nutrition and the microbiome. In A Silent Fire she interweaves the latest research with unusual case studies from her own practice to explain what we know about this elusive phenomenon. She debunks common myths about 'anti-inflammatory' lifestyles and explains the simple principles by which we can reform our relationship with food and our microbiomes to benefit our health.
