Nutrition writer & researcher
Emma is a nutrition writer and researcher focused on one question: how do you make healthy eating measurable without making it miserable? She has spent years testing food-logging apps, comparing their databases against primary sources, and digging through nutrition research to separate what actually works from what merely sounds scientific.
Her editorial rule is simple: every calorie figure, macro value and health claim must trace back to a primary source — USDA FoodData Central, peer-reviewed journals, or official dietary guidelines. If a number cannot be verified, it does not get published.
At ScanFood.AI, Emma covers food calorie guides, tracking techniques and evidence-based weight-loss topics for the blog.
