Final answer:
Cara should increase her iron intake by eating red meat, cooking in a cast-iron pan, and consuming vitamin C with her meals to improve iron absorption, but she should not drink milk with her iron supplement as it can interfere with iron absorption.
Step-by-step explanation:
To address Cara's diagnosis of iron-deficiency anemia, she should consider various dietary options to increase her iron intake. Consuming red meat weekly (eating several ounces of red meat weekly), which is high in iron, is beneficial, as is cooking her foods in a cast-iron pan, which can increase the amount of iron transferred to the food.
Additionally, consuming vitamin C-rich foods, such as orange juice, with meals (drink a glass of orange juice with her breakfast cereal) can improve iron absorption. However, she should avoid drinking a glass of milk with her iron supplement since the calcium in milk can interfere with the absorption of the iron supplement.
