British Journal of Nutrition is an international peer-reviewed journal that publishes original papers and review articles across the full spectrum of nutritional science. The focus of all manuscripts submitted to the journal should be to increase knowledge in nutritional science relevant to human or animal nutrition. The BJN welcomes manuscripts that report studies in nutritional epidemiology, nutritional requirements, metabolic studies, body composition, energetics, appetite and obesity. Manuscripts that address interactions of nutrition with endocrinology, genetics, immunology, microbiology, molecular and cell biology, neuroscience and physiology and that report outcomes relevant to health, behaviour and well-being are also within scope for the BJN.
