However, Japanese cohort data show suboptimal intakes of energy, macro\u2010 and micronutrients, with persistently low folate awareness and intake. Anemia (Hb &lt;\u200911\u2009g\/dL) is associated with adverse outcomes, and low vitamin D\/calcium status impacts maternal bone health. While medical nutrition therapy is standard for gestational diabetes, nutrient targets have not been set yet. Guidance for hypertensive disorder of pregnancy recommends sodium restriction but lacks comprehensive nutrient specifications. Evidence gaps include body mass index\u2010specific energy needs for appropriate gestational weight gain, robust diet\u2013fetal growth relationships, and actionable guidance for lactation and the preconception period.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusions<\/jats:title>\n                    <jats:p>The Dietary Reference Intakes for Japanese (2025) provide a necessary framework, yet significant implementation and evidence gaps remain.
