Where can we get a healthy supply of Iron daily?
Iron is not made in the body and must be absorbed from what we eat. The best sources of iron from food are vegetables, meat, poultry and fish. If we are not taking sufficient iron from food, it is recommended that we take iron supplements as an alternative.
The importance of red blood cells (RBC) in the body
RBC are the most abundant cells in the blood, accounting for 40-45% of the volume. Haemoglobin is a special protein within the RBC as it carries fresh oxygen from the lungs to the rest of the body and returns carbon dioxide from the body to the lungs for one to exhale.
What happens during menstruation?
Menstruating women lose iron through blood loss every month. Blood loss during this time is estimated to be as little as one ounce – a light or average period – and as much as 1 cup – a heavy period. Women with heavy periods may have more iron loss if their diet is lacking in iron-rich food such as vegetables or meat.
