Study suggests women and pregnant people are underrepresented in research to inform nutrition reference values

Girls and pregnant individuals are underrepresented within the research used to attract up the dietary steering supplied to People and Canadians, in keeping with a paper printed as we speak in Science Advances.

“Our analysis is the primary complete overview of the underlying analysis that informs nutrient reference values. These are used for therefore many issues: from creating federal meals applications to deciding what’s in your granola bar to figuring out the make-up of your prenatal nutritional vitamins,” Emily R. Smith, an assistant professor of train and vitamin sciences on the George Washington College, stated. “Our examine factors to gaps in information in regards to the actual degree of micronutrients we have to eat to guard the well being of ladies, together with pregnant girls.”
