Dr Andrew Morris is a clinical academic dietitian whose research focuses on improving nutritional care for people with chronic kidney disease (CKD).

His work examines how dietary management in CKD can be made more effective, practical and sustainable. He has particular expertise in potassium management, plant-based diets in CKD, and the behavioural and social factors that influence how people manage dietary recommendations. His research includes systematic reviews and meta-analyses, international mixed-methods studies of hyperkalaemia management, and qualitative research exploring patient experiences of renal dietary care and peer support.

Andrew also studies the relationship between nutrition, nutritional biochemistry and body composition in CKD, integrating clinical, biochemical and psychosocial approaches to understand how dietary interventions influence outcomes and are implemented in everyday practice.

He holds national and regional research leadership roles, including NIHR West Midlands Regional Research Development Network Renal Specialists Lead, NIHR Senior Research Leader and member of the NIHR Reviewer Development Scheme. He is an editorial board member for the Journal of Kidney Care and collaborates internationally on research to improve evidence-based approaches to nutrition in CKD.

Andrew’s research interests span:

Dietary potassium and plant-based eating in CKD – including the clinical and biochemical consequences of different dietary patterns, potassium additives and potassium-lowering strategies.

Nutritional biochemistry, body composition and the gut–renal axis – how dietary intake, serum markers and changes in muscle and fat mass interrelate with kidney outcomes, and how diet–gut–immune interactions (for example in IgA nephropathy) might inform renal nutrition practice.

Dietary self-management and lived experience – how people with CKD and their families understand, negotiate and implement dietary advice, and how consultation style, peer support and social context influence adherence.

Service delivery and implementation – evaluation of renal dietetic services, consultation approaches and research readiness within kidney care teams.

Andrew’s vision is for kidney nutrition practice to move beyond a primarily restrictive, risk‑averse model towards care that is mechanistically informed, evidence‑based and genuinely workable in everyday life. By bringing together nutritional biochemistry, body composition, gut–renal interactions and behavioural science with patients’ lived experiences, he aims to reduce unnecessary dietary burden and inequity, and to support kidney care teams to deliver dietary advice that is both safe and sustainable over the long term.
