1. Anemia

2. Description
a condition that develops when your blood lacks enough healthy red blood cells or hemoglobin.
Hemoglobin is a main part of red blood cells and binds oxygen.
If you have too few or abnormal red blood cells, or your hemoglobin is abnormal or low, the cells in your body will not get enough oxygen.

3. Causes
Anemia occurs when your blood doesn't have enough red blood cells. This can happen if:
Your body doesn't make enough red blood cells
Bleeding causes you to lose red blood cells more quickly than they can be replaced
Your body destroys red blood cells
Vitamin deficiency anemia. In addition to iron, your body needs folate and vitamin B-12 to produce enough healthy red blood cells. A diet lacking in these and other key nutrients can cause decreased red blood cell production.
Iron deficiency anemia. This is the most common type of anemia worldwide. Iron deficiency anemia is caused by a shortage of iron in your body. Your bone marrow needs iron to make hemoglobin. Without adequate iron, your body can't produce enough hemoglobin for red blood cells.
Sickle cell anemia. This inherited and sometimes serious condition is an inherited hemolytic anemia. It's caused by a defective form of hemoglobin that forces red blood cells to assume an abnormal crescent (sickle) shape. These irregular blood cells die prematurely, resulting in a chronic shortage of red blood cells.

5. Prevention
So it’s important to get a regular supply of iron as well as vitamin B12, folate, and protein. You can get these nutrients by eating a balanced diet or taking dietary supplements.
Common types of anemia can be prevented a by eating iron-rich foods. The best sources are red meat (especially beef and liver), poultry, fish, and shellfish. Other foods high in iron include peas, lentils, beans, tofu, dark green leafy vegetables such as spinach, dried fruits such as prunes and raisins, and iron-fortified cereals and breads.
