About us

Plant-based health professionals UK Ltd is a non-profit organisation dedicated to the promotion of whole food plant-based nutrition and other lifestyle interventions for optimal health and well-being. In addition to practicing conventional medicine, we are passionate about promoting health and well-being using whole food plant-based nutrition. There is no doubt that conventional medicine has resulted in some astonishing advances in patient care. However, the current model of healthcare in the UK focuses primarily on treating established disease, rather than emphasising interventions that could prevent or reduce the burden of chronic disease.

We hope to provide a valuable resource for the education of healthcare professionals and the general public alike in the field of lifestyle medicine, which is increasingly recognised as a speciality in its own right. The aim is to empower individuals to take control of their own health and share this information with patients, friends and their families.

She was able to show that supra-nutritional doses of selenium could enhance the action of chemotherapy in the laboratory. She has published a number of peer-reviewed papers in the field of lymphoma.

Shireen discovered the power of nutrition for the prevention and treatment of disease 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, reading scientific papers and books, attending nutrition conferences and completing recognised continuing professional development activities to keep up to date in the field. She has completed 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. With her medical and scientific training, Shireen is uniquely placed to interpret nutritional data and incorporate the latest findings into daily medical practice.

Kate Dunbar

Patient Advocate

As a stressed, 40 year old primary school teacher, Kate succumbed to inflammatory arthritis, later diagnosed as psoriatic arthritis. It seemed like every joint in her body was inflamed and in hindsight, she realised that she had suffered a few previous undiagnosed attacks over the years, but this was the most debilitating. Everything was extremely painful if not impossible; walking, sitting, and even sleeping. She was signed off work for a year. Thankfully with medication, her condition was brought under relative control. Soon after, 13 years ago, and with support from her husband, she embarked on a vegan diet and was able to slash her medication by more than half.

Only recently has she discovered whole food plant-based (WFPB) diet, and its amazing restorative and disease preventing benefits. At last she is completely in remission and medication free.

With a new lease of life, she is an active community member, founder of Hunstanton Community Orchard, graphic designer, ceramicist and community arts provider. She loves cooking and growing vegetables and has a small business making vegan food. She is a passionate advocate of plant-based nutrition and exercise.

She is beyond thankful that there are plant-based doctors and other health professionals who are championing a WFPB diet so that other people need not go through the torture of psoriatic arthritis and other dreadful health conditions.

Jay Cox

Director of Videography

Plant-based filmmaker and music producer Jay Cox rediscovered his lust for life after a cancer diagnosis. After a tough fight and with the disease in remission, he didn’t need any more reminders how short life really is, or any more encouragement to follow his passion. He changed his diet, became totally plant-based and, with new-found energy, got back on his mountain bike. He also got his camera out again and began looking for places he could make a real difference. This reinvention of himself, his life and his purpose lead him by chance to Tarifa in Spain with endurance athlete Luke Tyburski as he embarked on an insane 2,000km solo triathlon in 12 days. The result was the Ultimate Triathlon documentary, and the revelation of Jay’s formidable natural talent.

Jay has teamed up with plant-based health professionals to help achieve their mission to promote evidence based nutrition education.
