A vegetarian pregnant patient is concerned about meeting iron and zinc RDAs. Which combined strategy best synthesizes dietary and supplement recommendations to meet these micronutrient needs?

Recommend high-dose zinc supplementation alone because zinc corrects all micronutrient deficits in vegetarian diets without the need for iron monitoring

Advise only increasing dairy and avoiding legumes, because animal-based iron sources are the only effective option and supplements are unnecessary

Encourage iron-rich plant foods (legumes, fortified cereals, leafy greens), pair them with vitamin C sources to enhance non-heme iron absorption, and consider a prenatal supplement containing iron and zinc after discussing with her provider and monitoring labs

Suggest eliminating fortified foods because synthetic nutrients interfere with natural absorption and relying solely on cravings to guide intake
