Are you sleeping well, but still feeling really fatigued? Your problem might be anemia, which occurs when your body doesn’t make enough red blood cells. These are the cells that bring blood to your organs, and this issue affects about 3.5 million Americans, with the majority being women and more common among seniors because of poor diet or medical conditions. If you have anemia, or suffer from its symptoms, the good news is that your diet can help to turn the condition around.
