Health Benefits of Collard Greens

6. Prevent Anemia

People with anemia do not have enough healthy red blood cells to deliver enough oxygen to the tissues in the body. They often feel tired and weak, and anemia may be temporary or long-term. People with anemia also experience symptoms such as cold hands and feet, dizziness, pale or yellowish skin, and headaches. Iron-rich foods like collard greens can minimize some of these symptoms. A diet low in iron can negatively affect how well the body uses energy, and the folate in dark, leafy vegetables is a good option for fending off anemia.
