Dr Shireen Kassam


Dr Shireen Kassam is a Consultant Haematologist and Honorary Senior Lecturer at King’s College Hospital, London with a specialist interest in the treatment of lymphoma.

She is also a Visiting-Professor at Winchester University, Hampshire, where she has developed and facilitates the UK’s first University-based course on plant-based nutrition for health professionals. Shireen is passionate about promoting plant-based nutrition for the prevention and reversal of chronic disease and for maintaining optimal health after treatment for cancer. She discovered the power of nutrition in 2013 and since then has been following a whole food plant-based diet.

She has immersed herself in the science of nutrition and health, completing the eCornell certification in plant-based nutrition and in 2019 she became certified as a Lifestyle Medicine Physician by the International Board of Lifestyle Medicine. Shireen founded Plant-Based Health Professionals UK in 2017. This is a non-profit, membership organisation whose mission is to provide evidence-based education on whole food plant-based nutrition for the prevention and treatment of chronic disease.

Shireen qualified as a medical doctor in 2000, initially training in general medicine and then specialising in Haematology. During her training, she took time out to complete a PhD (University of London, 2011). Her research investigated the role of selenium, an essential micronutrient, in sensitising cancer cells to chemotherapy. She was able to show that supra-nutritional doses of selenium could enhance the action of chemotherapy in the laboratory. Shireen has published a number of peer-reviewed papers in the field of lymphoma.
