Hidden inflammation lies behind many modern diseases. Shilpa Ravella, an expert in nutrition and the gut, explains why our immune systems are turning against us and what we might do about it.

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 and the history of immunology 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.
