Iron Deficiency in Women Signs and Food Sources

Iron is an important nutrient that has various important functions in the body. Iron deficiency is very common especially in women. Low iron levels may not immediately cause noticeable symptoms. But as the iron deficiency increases especially in women, they may experience various signs and symptoms. Iron deficiency can be managed with a healthy balanced diet providing an adequate amount of iron, which is an important part of women nutrition.[1],[2]

Why Iron Is Important for Women

Iron is important to make haemoglobin, a protein which carries oxygen throughout the body. If the body does not have enough iron then it may not be able to make red blood cells which may lead to iron-deficiency anaemia. Hence, adequate iron is important for supporting everyday physical and mental functioning.

Women have some additional reasons to pay attention to their iron intake. During reproductive years, the iron is lost through menstrual bleeding. The amount of blood loss can vary from woman to woman, and heavier periods can increase iron requirements. Iron becomes important during pregnancy too. Therefore, maintaining adequate iron intake is important part of healthy women nutrition at different stages of life, mainly during reproductive years and pregnancy.1,[3]

Common Signs of Low Iron Levels

In the early stages, iron deficiency in women may not cause a lot of symptoms which are noticeable. Some women may only notice small changes in their energy or concentration. But with further low iron levels, symptoms can be more noticeable.

Common signs include:

  • Feeling tired or weak even after getting enough rest

  • Getting breathless more easily during physical activity

  • Feeling dizzy or light-headed

  • Headaches

  • Difficulty concentrating or feeling mentally tired

  • Feeling unusually cold

  • Pale-looking skin

  • Hair fall or brittle nails

  • Heart beating faster than usual

  • Craving or eating non-food items such as ice, chalk or soil (pica)

  • Restless legs, especially at night

Iron deficiency may not always cause these low iron symptoms in all the women. Some of them will have few to none symptoms in the early stages of the deficiency. 1,3

Factors That Can Affect Iron Intake

Eating foods that contain iron is important, but the amount of iron in the diet is not the only thing that matters. The iron that we eat through food is not entirely absorbed by the body. The type of iron, the other foods eaten with it and a person's health can all affect how much iron is absorbed.1,2

Eating a diet which is low in iron-rich foods or being a vegetarian and consuming a low protein diet may increase the risk of iron deficiency in women.  These are also important considerations when planning balanced women nutrition. There are two forms of iron - heme and non-heme iron. Body absorbs iron from animal foods (heme iron) better than plant foods. Plant foods (non-heme iron) also contain iron, but the body may not absorb much of it because certain compounds in plant foods reduce absorption of iron. [4]

Iron-Rich Foods to Include in Your Diet

A simple way to improve iron intake is to include an iron-rich food in regular meals instead of trying to get all the iron from one food. Good choices include lentils, pulses, soy products, green leafy vegetables, seeds, meat and eggs. Iron-fortified foods can also contribute to daily intake.

Someone who eats meat may get a good amount of readily absorbed iron from animal foods, while someone following a vegetarian diet may need to pay more attention to meal combinations that improve the absorption of plant-based iron.

Vegetarian Sources

A well-balanced vegetarian diet can also provide iron if its planned well. Some useful choices include:

  • Pearl millet

  • Whole red lentils

  • Pulses like chickpeas, kidney beans, horsegram

  • Soybeans, tofu and other soy foods

  • Seeds like onion seeds and garden cress seeds

  • Green leafy vegetables such as amaranth leaves, dill leaves

  • Iron-fortified cereals and other foods

For plant-based meals, it can be helpful to combine these foods with a source of vitamin C rather than eating them alone, as vitamin C helps in absorption of iron.

Non-Vegetarian Sources

Non-vegetarian sources of iron which contain heme iron include meat, poultry, and seafood and they are generally better absorbed than the non-heme iron found in plant foods. Some simple non-vegetarian foods that provide iron include lean meat like chicken, and fish. Eggs also contain some amount of iron. Having a variety of these foods during the week can help you get enough iron instead of depending on just one food source.[5]

Foods That Support Iron Absorption

The foods you eat with an iron-rich food can affect how much iron your body absorbs. Adding vitamin c rich foods while consuming iron rich foods can help increase the iron absorption. You can get it from foods such as amla, guava, oranges, lemon, tomatoes and capsicum. For example, adding lemon to pulse curries, dals etc can be simple ways to include vitamin C.

Tea and coffee are best avoided around iron-rich meals as they can reduce iron absorption. Soaking, sprouting and fermenting foods may also help improve the availability of iron from some plant foods.4

When to Seek Professional Advice

If you are feeling tired or dizzy, getting breathless easily, or having very heavy periods, talk to your doctor. These signs may be related to not just low iron levels but some other reason too. A doctor can help find the actual cause and suggest the right treatment.

A blood test can check haemoglobin and ferritin levels and help identify whether iron deficiency is present. If iron levels are low, it is also important to find out why. It is better not to start iron supplements on your own without first knowing why your iron levels are low.[6]

Conclusion

Being mindful of iron intake can help support your energy, focus and overall wellbeing. Small, consistent dietary choices can make a difference. Hence, focusing on women nutrition is important part of maintaining good health through every stage of life.
