In 2025, Doctor Shireen Kassam summarized key science papers that support plant-based diets as a path to improved health. She highlighted studies showing that life expectancy in Europe and the UK is stalling due to cardiovascular diseases and cancers, with diet-related risks playing a significant role. Plant-based diets were found to be nutritionally adequate, lower the risk of cancer, and contribute to better gut health compared to meat-based diets.

The evidence from the summarized papers aligns with planetary health frameworks calling for systemic shifts in the food system. Kassam emphasized the importance of translating scientific evidence into action, urging greater leadership from health systems and policymakers to promote plant-based diets and address the dual crises of global health deterioration and environmental degradation. She hopes to see changes in clinical guidelines, medical education, and public health strategy to prioritize preventive nutrition and sustainability for better health outcomes for individuals and the planet.
