Pregnancy/Maternity

The importance of iron during pregnancy

During your first prenatal appointment, your doctor will probably talk about dietary supplements or iron tablets because it is important.

It is much healthier for your body to absorb iron from food and it will help you avoid constipation. Why is iron so important during pregnancy? What foods are rich in iron?

Iron

Iron builds hemoglobin, the component of red blood cells that carries oxygen all around the body. If the blood lacks red cells (hemodilution), it is poorer in iron, poorer in oxygen and, of course, poorer in hemoglobin. That’s what we call anemia.

Anemia

Anemia results in general fatigue, paleness, decreased appetite and weight loss. It generally affects the mood, causing irritability and a lack of interest in the outside world.

Because of menstrual bleeding, women need more iron than men and are more likely to suffer from anemia.

Pregnancy

During pregnancy, the increase in blood plasma (the liquid component of blood) causes a normal drop in hemoglobin. This decrease begins at the 8th week of pregnancy and stabilizes between the 16th and the 22nd week. A pregnant woman should have a hemoglobin rate above 115g /L around the 22nd week. A rate under 100 g/L shows anemia. The higher the hemoglobin rate, the more in shape a woman will feel after giving birth.

To ensure your daily intake...
  • Eat an ingredient very rich in iron once a week (more than 7 mg)
  • In every meal, eat a vegetable or a fruit rich in vitamin C, essential to absorb iron (orange, tomato, lemon)
  • Always keep a little bag of dried fruits, nuts and seeds for snacking
  • Replace sugar by molasses in recipes (at least half and half)
  • Use prune juice often in juice mixes (half prune juice + half orange or apple juice) 
  • Sprinkle wheat germ on desserts
  • Sprinkle parsley on meat and vegetables
  • Avoid tea. It reduces the amount of iron absorbed. Replace it with raspberry tea. 

If you want to take a supplement, make sure that this supplement is made of “iron citrate”. It is much easier to assimilate.
