– the forever changing needs of iron over a woman’s lifespan

Iron + Our Needs

Did you know that Iron Deficiency is the most common nutritional deficiency in the world? To kick start women’s health week, I thought it would make sense to talk about Iron. Why? Well a woman’s iron requirements change many many times during her lifetime. Let’s have a deeper look at the changing Iron needs across the lifespan, common iron inhibiting foods and ways to adequately meet your individual needs.

Iron is an essential mineral. It is found in the red blood cells which carry oxygen to the body and also helps your immune system function.

So how much do we actually need?

Toddler years (boys & girls)7mg / day
Teenage girls 14-18 years15mg/day
Non pregnant women (19-50 years)18mg / day
Pre-menopausal women18mg / day
Post-menopausal women (51 years +)8mg / day
Pregnant women *especially 2nd and 3rd trimesters27mg/day
Lactating women9mg / day

How do we know when we are low?

The following symptoms are common when iron levels are low:

  • Fatigue & difficulty concentrating
  • Impaired immunity
  • Reduced physical ability to work (e.g. exercise)
  • Pale skin
  • Shortness of breath, dizziness & headaches
  • Brittle nails, cracking at the side of the mouth
  • decreased energy

Who’s at greatest risk?

  • Getting too little iron in the diet as a result of a poor diet or vegetarianism
  • Losing too much iron through bleeding from heavy menstrual periods
  • Pregnancy can cause iron deficiency due to the baby demands of iron from the mother’s stores
  • Growth spurts such as during your toddler & teenage years
  • Athletes, particularly those engaged in endurance sports, may also be susceptible as iron can be lost through sweating.
  • Ilcers or certain medications (ie – aspirin)

Iron – rich foods?

Iron is found in many different foods but the most absorbable form is haem iron (haem = blood) which is found in organ meats, beef, veal, chicken, pork, fish & seafood.

There is also non-haem (plant based) sources of iron available in the foods we eat. The most valuable sources of non-haem iron include tofu, eggs, legumes, lentils & beans (think kidney beans, green lentils, chickpeas), fortified cereals (WeetBix, AllBran), nuts and seeds, wholegrain pasta, rolled oats, brown rice, wholegrain bread, vegetables especially spinach & broccoli and dried apricots

What foods are iron inhibitors?

Unfortunately, we know that there are some key iron inhibitors- which makes iron absorption from non-haem sources more challenging. These inhibitors include:

Calcium
  • calcium (like iron) competes for absorption in the body.
  • TIP: Avoid calcium-rich foods such as dairy and calcium supplements with or around mealtimes.
Tannins
  • found in tea, coffee and red wine
  • TIP: Avoid drinking tea & coffee within 30 minutes of the main iron-containing meal
PhytatesA type of antioxidants found in wholegrains, legumes, nuts & seeds (i.e. where you find lots of non-haem iron)

TIP: Unfortunately, not much you can do about this

ZincOften found in similar foods to iron-rich foods is another mineral that competes for absorption in the body.

TIP: Unfortunately, not much you can do about this

Enhancers

As opposed to iron-inhibitors, we know of a few iron-enhancers – which can, as implied, aid iron absorption.

Vitamin C (ascorbic acid)
  • found in tomatoes, broccoli, capsicums, citrus, kiwi, strawberries and lots of other fruits and veggies helps with the absorption of non-haem iron.
  • TIP: Try eating vitamin C rich foods with vegetarian meals to increase the amount of iron absorbed.
Other acids (citric acid)Can help with absorption

TIP: Add some vinegar or lemon or other citrus juice to your leafy greens to aid with the iron absorption.

Still lost?

It is best to first have a blood test to determine your iron levels. After this time, if you are still unsure whether you are having the right amount and type of iron, book in with a dietitian (me) to further explore your diet, your needs depending upon your age and lifestyle and ways to get the most out of the foods you eat.

Our Values

Our values are the basis of everything we do at Fitwise.

Excellence, Respect, Innovation and Fun – For our clients, for our team and for ourselves.

This is evident with the service we provide, the environment in which we provide it, the way in which we operate as a team and how we care for and value our clients, referral partners and ourselves; we live the Fitwise values every day.

Our culture is one where everyone feels supported, respected and safe. Our clients and our team, experience a leading-edge health environment where we remember to have fun along the way.

Our Story

In 2004, Gen McGlashan and Libby Oldfield founded Fitwise Physiotherapy. They first met in 1994.  Libby was Gen’s physio when she had her first child. Gen then worked for Libby for 10 years in Libby’s previous business, located at the Epworth Freemasons Maternity Unit in East Melbourne. They have been a team working together for a very long time!!

Libby and Gen have always had a passion for empowering women, by helping provide accurate evidence based information and treatment to help women live their best lives. Excellence in all that they do, practising and operating in an innovative way has always been their core. Fitwise was the first multi-practitioner practice providing Women’s Health physiotherapy consultations, exercise classes and clinical pilates in Melbourne.

Gen and Libby

In February 2005 Gen and Libby moved their one room practice to Albert St East Melbourne. They had expanded to 2 treatment rooms, an exercise studio and a pilates studio with a small team of physiotherapists and one receptionist. This was exciting as they wanted to be able to help more people and to grow their team – enabling their other passion: teaching and mentoring clinicians who also wanted to work within the Women’s, Men’s and Pelvic Health arena.

5 years later, they expanded their East Melbourne clinic and in 2015 opened their second clinic in Armadale.

Remedial Massage, Myotherapy and Dietetics have been an exciting addition in recent years, with Podiatry and Exercise Physiology being added in 2022.

The Fitwise team has now grown to include 18 amazing practitioners and 12 wonderful administrative team members and is still growing!

Libby and Gen have always loved providing a holistic service, treating a variety of conditions in consultations and providing exercise appropriate for different life stages. The community of clients that are part of the Fitwise family, (some who have been part of the journey from the very beginning – over 17 years ago), are the biggest reason they do what they do. For Gen and Libby, it is a privilege to be part of these wonderful people’s lives.
