This information comes out of a new study published in the April 2011 issue of the Journal of the American Dietetic Association and it flags up a warning that for postmenopausal women in particular an inadequate nutrition intake is linked to a greater risk of anaemia.
I would have thought that an inadequate nutrition intake was a risk at any age, but the lead investigator, Cynthia A. Thomson, PhD, RD, Associate Professor Nutritional Sciences at the University of Arizona, believes that menopausal and older women are particularly at risk. She also highlights the fact that taking multivitamin/mineral supplements to counteract this poor diet does not affect the rates of anaemia in this age group – helpful though they may be for general health and wellbeing.
The problem here is iron deficiency, which many women do suffer from – particularly during their reproductive years – and the symptoms are often just ‘lived with’. They include:
•Fatigue
•Weakness
•Fainting
•Breathlessness
•Heart palpitations (rapid or irregular beating)
•Dizziness
•Headache
•Ringing in the ears (tinnitus)
•Difficulty sleeping
•Difficulty concentrating
If you wonder if you are suffering then these are the most common signs:
•Pale complexion
•The normally red lining of the mouth and eyelids fades in color
•Rapid heartbeat (tachycardia)
•Abnormal menstruation (either absence of periods or increased bleeding)
Interestingly there have been few studies of anaemia and diet relating to women in the past 20 years, despite it being widespread from minor to major impact.
Using data from 72,833 women in the Observational Cohort of the Women’s Health Initiative the researchers found that deficiencies in more than a single nutrient were associated with a 21% greater risk of persistent anaemia while three deficiencies resulted in a 44% increase in risk. Women with anaemia also reported lower intakes of energy, protein, folate, vitamin B12, iron, vitamin C and red meat. In fact, inadequate intake of dietary iron, vitamin B12 and folate were each associated with approximately 10% to 20% elevated risk.
Postmenopausal women need to ensure an adequate intake of anaemia-associated nutrients including iron, vitamin B12 and folate. An anti-anaemia diet usually consists of an iron-rich diet along with iron supplements. Absorption of iron from food is influenced by multiple factors. One important factor being the form of the iron. Heme Iron, found in animal sources, is highly available for absorption. Non-heme iron on the other hand, found in vegetable sources, is less available.
A diet to avoid anaemia should include:
Good sources of heme iron that the body can easily absorb include: Oysters/Mussels/Shrimp/Sardines/Liver/Beef/Turkey
Good sources of non-heme iron include: Enriched breakfast cereals/cooked beans and lentils/pumpkin seeds/molasses/canned beans/baked potato with skin.
These foods enhance the absorption of iron:
Meat/fish/poultry/oranges & juice/cantaloupe/strawberries/grapefruit/broccoli/brussels sprouts/tomatoes & juice/potatoes/green & red peppers/white wine
These foods inhibit the absorption of iron:
Red wine/coffee/tea/spinach/chard/rhubarb/sweet potato/whole grains and bran/soy products
