If your red blood cell (RBC ) count is low, it is important to consume a nutritious diet that supports RBC production. Foods rich in iron, such as lean meats, poultry, fish, leafy green vegetables, legumes, and fortified cereals, can help increase iron levels and support RBC production. Additionally, foods high in vitamin B12, such as meat, fish, eggs, and dairy products, can be beneficial. Folate-rich foods like dark green leafy vegetables, beans, lentils, and fortified grains are also important. However, it is recommended to consult with a healthcare professional or a registered dietitian for personalized dietary recommendations based on your specific condition and needs.
