Patients with iron-deficiency anemia need to undergo pharmacological treatment with oral or injective iron supplements. In addition, patient health education should be enhanced to guide them in following a scientific and reasonable diet. For example, patients who are picky eaters or have insufficient intake should change their dietary structure and lifestyle in order to increase iron intake and bioavailability. This ensures that all key nutrients involved in the production of red blood cells are sufficient. Moreover, it is necessary to increase the intake of iron-rich foods, mainly including animal liver, blood, as well as soybeans, black fungus, egg yolks, brown sugar, lean meat, sheep kidneys, dried fruits, and sesame paste.
