Iron deficiency anemia: a BIG productivity issue Print

Iron Deficiency Symptoms, Treatment and Eating Strategies

Iron deficiency is the most common nutrient deficiency in the world.  Failing to get enough iron remains a common problem for several high-risk groups in Canada, the United States and beyond.

Understanding iron deficiency is a key problem influencing schools since failing to get enough iron can lead to an inability to learn and concentrate. Iron deficiency anemia is also a key issue employers need to understand and detect in biometric screening and health risk assessments since it is directly tied to health issues, workplace productivity and performance.

 

What is iron deficiency anemia?

 

Iron is an essential mineral needed by every cell in your body throughout your life. One of the key functions iron has is to form haemoglobin in your red blood cells to carry oxygen from your lungs to all parts of the body.

Iron deficiency anemia occurs when your body doesn’t have enough iron to make haemoglobin, which causes a low level of red blood cells. Without enough red blood cells, your body can’t supply enough oxygen, leading to fatigue, exhaustion and other health effects.

 

What are the signs of low iron?

 

You may experience no symptoms with initial iron depletion (which occurs before iron deficiency anemia). Working with your physician for regular blood screening is the best way to ensure you are keeping an eye on your blood work trends.

 

Signs and symptoms of iron deficiency anemia may include:

 

  • Fatigue and exhaustion
  • Sleeping more yet still waking and feeling tired
  • Inability to focus or concentrate at work or school
  • Dizziness, headaches or light-headedness
  • Mood changes and irritability
  • Run down immune system and more frequent illness
  • Poor physical activity performance and shortness of breath in manual labor jobs or playing sports
  • Slow social and cognitive development in children
  • An inflamed tongue (glossitis)
  • Paleness
  • Cold hands and feet
  • Hair loss and brittle nails

 

Who is at risk for iron deficiency?

 

Although anyone can develop iron deficiency anemia, here are a few of the higher-risk groups:

Women

Women that have heavy menstrual blood loss are higher risk for iron deficiency.  Pregnant and breastfeeding women have an increased need for iron.

Infants, children and teens

Rapid growth causes an increased need for iron.  Breastfed babies that are not provided with iron-fortified cereals or other high iron solid foods at 6 months of age are at risk along with formula fed babies that are not fed iron-fortified formula.  Excessive intake of milk (over 750ml per day for kids aged 1-5), juice or pop can limit an appetite for iron dense solid foods.

Vegetarians

Vegetarians are at higher risk of iron deficiency overall since their diet contains non-heme iron which is poorly absorbed compared to heme iron.

Athletes

Hard training, particularly in endurance sports and high altitude training increases the need for red blood cells and therefore iron.  Athletes also can lose iron in sweat as well as in sports such as running, some red blood cells get crushed on foot strike.

Chronic diseases

If you are living with certain chronic diseases such as cancer, ulcerative colitis or undetected/poorly managed celiac disease, or if you are taking certain medications your iron levels may be affected.  Speak to your physician to find out more.

 

How is iron deficiency anemia treated?

Since getting too much iron can be toxic (particularly in children), DO NOT take extra iron supplements without first speaking with your physician to have your blood work screened.

If you are diagnosed with iron deficiency anemia, work with a Registered Dietitian to review the amount and type of iron supplement that is best for you along with adjusting your everyday nutrition to maximize iron-rich foods.

 

How can I maximize the iron in my diet?

 

1.  Choose high iron foods

Heme iron from meat, poultry, fish and seafood are high in iron and absorbed approximately twice as well as non-heme iron from plant based protein sources such as fortified cereals, legumes, nuts and spinach.

If you are vegetarian or choose not to eat much meat, poultry and fish, work with a Registered Dietitian to help you customize a plan that ensures you are getting enough iron through other foods. For a general overview of a healthy vegetarian diet check out this previous article on our blog: How to Plan a Healthy Vegetarian Diet.  Cooking with cast iron pans also increases iron absorption of your meals.

 

2.  Eat iron rich foods with a source of Vitamin C

Vitamin C greatly increases the amount of iron you absorb out of a food.  Choose vitamin C rich vegetables and fruit such as citrus fruits, tomatoes, potatoes, kiwis, peppers, cantaloupe, broccoli and berries with iron rich meals.

 

3.  Be aware of factors that decrease iron absorption

Avoid drinking coffee or tea at high iron meals since these decrease iron absorption.  Be sure to take calcium supplements at different times than supplements containing iron as these two minerals compete for absorption.  Be aware that overuse of antacids can decrease stomach acidity which is important for iron absorption.

Success stories

"I am a psychologist in private practice and it is very important to me that my clients have the best care with other health care professionals. For that reason Health Stand Nutrition is my only source for exceptional Dietitians. Andrea and her team provide highly knowledgeable, compassionate, and real world support to my clients who require assistance with food lifestyle. I trust my clients to them and you would be in excellent hands making them part of your health care team."
Adele Fox, Psychologist
“This is the first time I feel satisfied; my cravings have diminished dramatically and I have a whole new relationship with food. I am eating guilt-free for the first time in my life. My energy has also dramatically increased and I feel great!
Rhonda Jenkins, Nutrition Counseling Client
“The Dieticians at Health Stand Nutrition help you to take action on the science behind eating well by making it practical, understandable, and fun. Their office is cozy and not at all clinical or intimidating. I felt like I was sitting down with a really smart, caring friend who wanted to help me make the best choices for my lifestyle and food preferences. Andrea and her team really are the best in the business.”
Marty Avery, Nutrition Counseling Client
“I have come to think of the program as a one stop shopping excursion for everything one needs to know about creating a joyous relationship with food and our bodies. In a single word, the course has gifted me with freedom from the punishing rigidity of disordered eating, old stories that never were true, and body dysmorphia that did nothing but make me lose sight of a body that has done everything I've asked, despite my careless dismissal of her needs. Now when I look in the mirror I find myself shifting from harsh criticism to gentle gratitude.”
Lynn Haley, Pursuit of Healthiness Online Course Participant
“I spent 3 hours when first diagnosed with type 2 diabetes. I learned more from my Dietitian about food in those 3 hours than I had learned in all the years of my life. I also love the newsletter, there is always something to learn.”
Peter Whitehead, Nutrition Counseling Client
“I didn’t realize how strong my “diet mentality” was, and all the rules I had in my head about food. I was in a cycle of reward/punish/binge/cringe. I booked with your business very reluctantly, on the repeated advice of my doctor, to get my slowly rising cholesterol levels in check. I thought I knew everything about food, and my behaviour with food, but I was definitely re-schooled. My weight is creeping down, I feel good about my diet, exercise, body image, and lifestyle.”
Amy Floyd, Nutrition Counseling Client
“Thanks Andrea for an amazing presentation, I have heard all positive remarks from attendees and the evaluations show the same sentiment. It is really gratifying when a speaker does their “homework” and weaves in our profession’s day to day challenges within their content, you did an awesome job of this! You truly took the “die” out of Dietician! Your information on healthy eating and simplifying how we can work towards this as we are all so busy really hit the mark. Andrea connects very well with her audience; she is energetic, funny, and very approachable.”
Carole Ann LaGrange, Transfusion Medicine Safety Officer

Event Planner for Laboratory Diagnostic Imaging Annual Event

I am a family physician who sees patients with a myriad of eating concerns – from wanting to know how to plan healthy meals for active families, to weight loss, to eating disorders, and so on. I cannot recommend the Health Stand team highly enough. I have worked with (and been to!) other Dieticians in the past and too often find that they just ask for food logs and make suggestions that are easily obtained online or in books. The Dieticians at Health Stand offer much more than just telling clients what they “should be eating.” In contrast, the team really does more of a counselling practice, and they work hard to help their clients learn more about why their eating habits may be off track and not optimal for them, as well as helping people to effect change at a deep level that, most importantly, is sustainable for lifetime health.”
Dr. Deb Putnam, Family Physician

Nutrition Counseling Client & Referring Physician

“I am a busy mom, with kids in high level sports, working full-time downtown, and running our home acreage outside the City. I now have the knowledge and tools I need to plan for and manage the chaos of meal planning.”
Gillian Gray, Pursuit of Healthiness Online Course Participant
“As a construction company, we select speakers who can relate to our industry and its employees. Andrea’s message was delivered with humor and empathy. She makes people feel as though they can make changes without leaving behind every favorite food. Andrea focused her presentation on healthy eating as a way to keep energy high throughout the day. This message and the way it was delivered resonated with our predominantly male, blue collar culture. I would highly recommend Andrea as a speaker for groups such as ours. She will get your message across without alienating anyone in your audience – which is a huge hurdle when trying to introduce a wellness program in the workplace!”
Stephanie Wood, HR and Safety Manager

Fisher Construction Group, Burlington, WA

I found my Dietitian warm, funny, and skilled at teaching nutrition concepts without the overwhelm. The general approach of each session was to mix science with emotion, which was exceedingly effective in helping me shift my perspective on food from one of anxiety to one of joy and curiosity.”
Erin Kronstedt, Nutrition Counseling Client
“Excellent presentation! What a refreshing change to have a speaker inspire rather than “lecture” about nutrition. Your captivating stories, tips and overall approach to healthy eating uplifts and puts people at ease. It was great to hear we don’t need to strive to be perfect eaters, and that small changes really can make a difference in how we feel and in our health. Thanks to Andrea, we have solutions to our everyday nutrition challenges that can actually work in real life!”
Tina Tamagi, Human Resources

ARC Resources Ltd.

“Had I not joined this course I would have struggled with no focus, low energy, and mindless eating. Andrea is an excellent teacher and motivator. This is not just a course, it is a nutrition club with mentorship, support, and connections with other people with similar situations.”
Lorri Lawrence, Pursuit of Healthiness online course participant
