BMC Nutrition is an open access, peer-reviewed journal that considers articles on all aspects of nutritional sciences, including public health nutrition and global interventions, nutritional epidemiology, the biological underpinnings of nutrition in the body, clinical nutrition, health and nutrition throughout the life course, and dietary supplementation for improvement in health and performance. The journal also welcomes papers on developments in nutritional research tools and novel technologies. As a BMC Series journal, BMC Nutrition does not make editorial decisions based on the perceived interest or potential impact of a study. Manuscripts are considered for publication if they are scientifically valid. For research articles, this includes having a clearly defined and sound research question, appropriate methodology and analysis, and adherence to community-agreed standards relevant to the field.
