We are so excited to be back In The Nutshell as we kick off season six with dual qualified NHS Consultant Dermatologist and nutritionist Dr Thivi Maruthappu.
We cover the inflammatory condition, psoriasis, and find out why it is considered a systemic condition, and how it links to obesity, cardiovascular disease, and metabolic health. Dr Thivi outlines the potential mechanisms through which diet and lifestyle influence systemic inflammation, immune pathways, and the gut microbiome.
We take a closer look at the APPLE study (Asking People with Psoriasis about Lifestyle and Eating), co-led by Dr Thivi and researchers at King’s College London, exploring how overall diet quality relates to psoriasis severity, and how dietary patterns rich in plant-based foods are associated with better outcomes, providing important data that lifestyle and dietary assessments have a key role to play alongside standard clinical care.
