Anemia is a blood disorder characterized by a shortage of either red blood cells or hemoglobin.
It can leave people feeling frequently exhausted and sluggish, says the National Institutes of Health (NIH).
To prevent or counter anemia, people must get enough iron. Eating a balanced diet or taking dietary supplements are the simplest ways to get a regular supply of iron.
The best food sources of iron are red meat, poultry, fish and shellfish. Other high-iron foods include peas, lentils, beans, tofu and dark green leafy vegetables.
For pregnant women, the NIH says extra iron should be consumed to prevent anemia and the possibility of giving birth to iron-deficient children.
