Hannah Pearce

Hannah studied nutritional science at the University of Leeds before moving into health journalism, drawn by the gap between what nutrition research actually shows and what most headlines claim. She has spent six years writing about food, diet, and everyday wellness for UK health and lifestyle publications, with a particular interest in separating well-established nutritional guidance from emerging or contested claims. Her approach is grounded and practical — she writes for readers who want to understand their choices, not be sold the next trend. She lives in York and is a committed, if occasionally chaotic, meal-prepper.
