Iron-deficiency anemia occurs when an individual’s red blood cells lack an efficient amount of hemoglobin, thus causing a decrease in the amount of oxygen delivered to tissues. Without the proper amount of oxygen, the cell’s energy metabolism becomes limited.
of iron-deficiency include tiredness, apathy, the tendency to feel cold,

is usually caused by malnutrition, either from lack of food or high
consumption of the wrong food. More
often then not, we choose foods high in sugar and fat and only consume
minor amounts of iron-rich foods, such as beef and legumes.
Iron absorption can also be hindered by what we consume. For example, tea, coffee, soy protein, and fiber interfere
with the absorption of iron found in normal foods.
Among non-nutritional cause of iron-deficiency, blood loss is the
primary cause. This is due to
the fact that 80 percent of our iron is housed in the blood. A woman’s menstrual cycle causes her to require twice as
much iron than a man.
RDA suggests iron intake of 10 milligrams a day for men and older women. For women of childbearing age, 15 milligrams is needed to
replace menstrual losses. During
pregnancy, women need 30 milligrams of iron a day.
It is wise to note here that too much iron can be toxic.
