Sarah Berry

Professor Sarah Berry is a leading nutrition scientist specialising in personalised nutrition and how individual responses to food shape long-term health. As Professor of Nutritional Sciences at King's College London and Chief Scientist at ZOE, she leads the PREDICT programme, the world's largest in-depth nutritional research study with over 200,000 participants globally, exploring genetics, microbiome science, and metabolism. Her work translates complex nutritional science into practical, personalised strategies that help organisations and audiences move beyond generic dietary advice, empowering individuals to make informed food choices that support sustainable health and wellbeing.

Professor Sarah Berry has led more than 35 human nutrition studies investigating how dietary components influence disease risk, building one of the most comprehensive bodies of evidence in personalised nutrition science. As Professor of Nutritional Sciences at King's College London and Chief Scientist at ZOE, she has pioneered research that challenges the traditional one-size-fits-all approach to diet, demonstrating that individuals respond to the same foods in profoundly different ways. Her work spans cardiometabolic health, postprandial metabolism, and the structural effects of food and fat, with a particular focus on understanding how genetics, microbiome composition, and metabolic patterns combine to shape health outcomes. Through the PREDICT programme, which has enrolled over 200,000 participants globally, she has created the world's largest in-depth nutritional research study of its kind, generating insights that are reshaping both academic understanding and real-world dietary guidance.

Her career reflects a rare combination of rigorous academic leadership and practical application. At King's College London, she has established herself as a trusted authority in nutritional sciences, whilst her role at ZOE has enabled her to translate complex research into tools that support individuals in making informed food choices. By integrating novel technologies, remote clinical trial models, and citizen science, she has transformed how large-scale nutrition research can be conducted, making it more inclusive, efficient, and responsive to real-world needs. Her contributions extend beyond the laboratory, influencing public health conversations and professional practice through scientific publications, media engagement, and advisory work. This dual focus on advancing knowledge and improving accessibility has positioned her as a leading voice in the evolving field of personalised health.

Sarah equips audiences with a clear, evidence-based understanding of why generic dietary advice often fails and how personalised approaches can deliver better outcomes. She demystifies the science behind individual responses to food, offering practical frameworks that organisations, health professionals, and individuals can apply immediately. Her presentations move beyond theory, providing actionable strategies for managing health through nutrition in ways that are sustainable, measurable, and tailored to individual needs. Audiences leave with renewed confidence in their ability to make informed decisions about diet, alongside a deeper appreciation for the role of science and technology in supporting long-term wellbeing. Her work empowers people to move from confusion to clarity, transforming how they think about food, health, and the future of nutrition.
