Final answer:
To meet the increased RDA for iron during pregnancy, a woman may need a low-dose iron supplement and should increase her intake of iron-rich foods. It is important to also consume vitamin C to help with iron absorption and have a balanced approach to diet and potentially supplementation.
Step-by-step explanation:
The Recommended Dietary Allowance (RDA) for iron during pregnancy is significantly higher than during other life stages, with pregnant women needing 27 mg daily. To reach this elevated requirement, the pregnant woman may need to take a low-dose iron supplement. However, it is also beneficial to increase the intake of iron-rich foods, which include shellfish, such as clams and oysters, red meats, like beef, as well as seeds, nuts, and legumes. Additionally, the consumption of vitamin C alongside iron-rich foods can enhance iron absorption. It's essential to focus on nutrient-rich foods and not simply double caloric intake, as the myth that a pregnant woman needs to 'eat for two' can lead to excessive caloric consumption without addressing specific nutrient needs.
Furthermore, cooking in iron cookware can also contribute to increasing iron intake, although this may not be sufficient to meet the increased demands of pregnancy on its own. A balanced approach that includes dietary changes and, if necessary, supplementation as per healthcare advice is generally the best course of action to ensure adequate iron intake during pregnancy.
