Iron Deficiency AnemiaSara Merley

Nutrition – Professor Brown

Definition Iron deficiency anemia is caused from a

shortness of iron in the body. “[Iron] is a component of hemoglobin (which transports oxygen within red blood cells) and some enzymes” (Hoehn, Marieb).

The iron-rich protein, hemoglobin, is essential to the transportation of oxygen to the body’s tissues.

In America, there are over 3 million people effected by anemia.

Heme vs. Non-HemeHEME IRON – “Iron provided from animal

tissues in the form of hemoglobin and myoglobin. Approximately 40% of the iron in meat is heme iron; it is readily absorbed” (Wardlaw).

NON-HEME IRON – “Iron provided from plant sources and animal tissues other than in the forms of hemoglobin and myoglobin. Non-heme iron is less efficiently absorbed than heme iron; absorption is closely dependent on body needs” (Wardlaw).

Symptoms of IDA Paleness or “Sallow Skin”

Extreme fatigue / lack of energy

Chest pain

Shortness of breath

Headaches

Feeling weak

Rapid heart rate

Sore or smooth tongue

Poor appetite / unusual cravings for non-nutritional substances such as ice or clay.

An uncomfortable crawling feeling in your legs

Cold hands and feet

Irritability

Brittle Nails

Common Causation of Iron-Deficiency

Anemia 1) Most predominately, lack of iron within

the food one consumes.

2) Blood Loss; most prevalent in women because of menstruation.

3) Pregnancy; because of the increased blood volume and source of hemoglobin as the fetus grows.

4) Inability to absorb the iron consumed into one’s bloodstream.

Population DistributionBecause iron-deficiency anemia can simply

be caused by lack of iron in the diet, it can happen at any time in a person’s life. There are factors in which it appears to be more common however:

Women with heavy menstrual bleeding.

Women whom are pregnant or breastfeeding with recently given birth.

People with a gastrointestinal disease such as Celiac or Crohn’s disease.

Vegetarians and Vegans.

Other Causes of IDA:

Hemorrhoids

Frequent blood donations

Intravascular Hemolysis (condition where RBC break down in the blood stream then causing a release of excess iron into the urine).

Stomach / Bowel Ulcers

Lack of Iron in One’s Diet;

How much is enough? Women 19-50 years old need to consume 18

milligrams per day. Men (all ages) and women over 50 only have to consume 8 milligrams.

Diet is one of the most prevalent ways of becoming iron-deficient anemic. Especially in women 19-50 whom do not consume a great deal of iron-rich foods.

Diagnosed, how much is enough?

In patients diagnosed with iron-deficiency anemia it is recommended that they consume 2 – 5 milligrams per kilogram of body weight per day.

Still is highly advised to discuss the proper amount with one’s doctor.

Diagnosis Process IDA is diagnosed through a blood test of a

complete blood count; when someone is diagnosed the test results usually show: Low hemoglobin and hematocrit Low mean cellular volume Low ferritin Low serum iron High transferrin Low iron saturation

Iron-Rich Foods Clams (3 ounces) 14 milligrams

Spinach (1 cup) 6.4 milligrams

Kidney Beans (1 cup) 5.3 milligrams

Pot Roast (4 ounces) 3.9 milligrams

Sirloin Steak (4 ounces) 3.8 milligrams

Garbanzo Beans (1/2 cup) 2.4 milligrams

Baked Potato (average 1) 1.7 milligrams

More general food overview

MEAT: beef or lamb; especially organs meats and dark meats.

FISH: primarily shellfish.

LEAFY GREENS: broccoli and turnip greens.

LEGUMES: Lima beans, peas, and black-eyed peas.

IRON-ENRICHED: pastas, grains, and cereals.

More Iron Cook with a cast-iron

pan; some of the iron will

be absorbed into the food.

IRON supplement;

In my opinion, the best iron supplement is “Slow FE” since taking an iron supplement can cause constipation.

Absorption of IronVitamin C is extremely helpful to the

absorption of iron. As one consumes iron, vitamin C will wrap around the iron ions protecting it against destruction from stomach acid; so that then the iron may reach the small intestine where it is absorbed in the duodenum and first part of the jejunum.

Interesting fact: children are encouraged not to drink more than 16 to 24 ounces of cow’s milk per day because it can in turn, inhibit the absorption of iron.

Other treatment

Red blood cell transfusions – are performed for patients with severe iron-deficiency anemia. For example, severe bleeding, chest pain, and weakness.

Intravenous Iron – this is used for iron-deficient patients whom, have the tendency to not absorb iron well in the gastrointestinal tract, have extreme blood loss, are receiving a hormone that increases blood loss, or cannot tolerate taking an iron supplement.
