Mike Rayner

Professor Mike Rayner is a leading researcher in population health at the University of Oxford's Nuffield Department of Population Health within the Medical Sciences Division. His work bridges public health nutrition and environmental sustainability, focusing on population-level interventions to promote healthier and more sustainable diets.

Rayner's research spans several interconnected domains: public health promotion, diet and nutrition policy, obesity prevention strategies, and the environmental impacts of food systems. His work examines how environmental determinants shape dietary behavior and evaluates interventions like food taxes, labeling systems, and marketing restrictions to improve population health outcomes while reducing environmental footprints.

His recent publications reveal a strong emphasis on quantifying the environmental impacts of food products, developing sustainable dietary patterns, and assessing policy mechanisms like eco-labeling and meat taxation. The research demonstrates how food policy can simultaneously address public health challenges like obesity and cardiovascular disease while contributing to climate change mitigation.

Rayner actively engages with policy makers through evidence-based research on sugar taxation, sustainable food labeling, and dietary guidelines. His work with international organizations like WHO informs global approaches to food system transformation.
