No. There are no distinctive nutritional requirements associated with pregnancy.
Essential nutrient requirements to support pregnancy can be met by diet modification.
The Institute of Medicine (IOM) established nutrient recommendations to meet
essential nutrient requirements associated with pregnancy. Pregnancy is one of the
twelve life stage groups identified by the IOM. For each life stage group, where data
were available, IOM established dietary reference intakes (DRIs) to apply to the
healthy general population. DRIs are standards for apparently healthy people and are
not meant to be applied to those with acute or chronic disease or for the repletion of
nutrient levels in previously deficient individuals.
