Final answer:
To meet the higher RDA for iron during pregnancy, which is 27 mg daily, pregnant women may need to consume more iron-rich foods and possibly take supplements. They should also eat vitamin C-rich foods to improve iron absorption and consult with healthcare providers to monitor iron levels.
Step-by-step explanation:
The Recommended Dietary Allowance (RDA) for iron during pregnancy is significantly higher due to increased demands by the body to support fetal development. Pregnant women need about 27 mg of iron daily. To achieve this level, a combination of dietary adjustments and possibly supplementation might be necessary. Good dietary sources of iron include shellfish, red meats, seeds, nuts, legumes, and iron-fortified breakfast cereals.
Moreover, consuming these iron-rich foods along with vitamin C-rich foods can enhance iron absorption. In some cases, particularly when dietary adjustments cannot fulfill the increased iron needs, iron supplements may be prescribed. It is essential for pregnant women to monitor their iron status with their healthcare provider, especially if they're at risk of iron-deficiency anemia, to ensure they're getting enough iron for themselves and the developing fetus.
