Study Suggests Women And Pregnant People Are Underrepresented In Research To Inform Nutrition Reference Values

Ladies and pregnant individuals are underrepresented within the research used to attract up the dietary steering offered to Individuals and Canadians, in accordance with a paper printed right this moment in Science Advances.

“Our analysis is the primary complete evaluation of the underlying analysis that informs nutrient reference values. These are used for thus 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 diet sciences on the George Washington College, stated. “Our examine factors to gaps in data in regards to the actual stage of micronutrients we have to eat to guard the well being of women, together with pregnant women.”

Smith and her colleagues reviewed all the research that underpin the reference values for micronutrients established within the Dietary Reference Values for the US and Canada.

The crew discovered that just about one quarter of the research included males solely, and in analysis that did embody ladies, female participants have been underrepresented in comparison with males.
