“…Meat is the main source of well-absorbed iron, and it enhances the absorption of non-heme iron. In our study, as in the work of Bairati et al (1989) and Preziosi et al (1994), ascorbic acid intake, which is experimentally considered as a powerful enhancer of iron absorption, was not associated with any of the biological iron status indicators. Previous studies revealed that vitamin C was positively related to serum ferritin (Kenney, 1985;Hercberg et al, 1987).…”

The iron status of a national sample of adults living in France and participating in the SU.VI.MAX cohort, was assessed using serum ferritin and hemoglobin concentrations. Complete data were obtained for 6648 women 35 ± 60 y old and for 3283 men 45 ± 60 y old. Assessment of iron dietary intakes was realized on a subsample of 3111 women and 2337 men who reported six 24 h dietary records during a one-year period; 22.7% of menstruating women and 5.3% of post-menopausal women presented a total depletion of iron stores (serum ferritin`15 mgal). Iron-de®cient anemias were found in, respectively, 4.4% and less than 1% of these women. Three-quarters of the anemias were related to iron de®ciency in menstruating women. In men, iron depletion and iron de®ciency anemia were very rare. Post-menopausal women had much higher serum ferritin levels than menstruating women. In menstruating women, those using intrauterine devices had signi®cantly lower serum ferritin levels than those without contraception, and much lower than those using oral contraception. The frequency of iron depletion reached 28.1% in women using intrauterine devices, but only 13.6% in those using oral contraceptives. The mean iron intake was 16.7 AE 5.7 mgad in men and 12.3 AE 3.4 mgad in women. Heme iron represented respectively, 11.1 and 10.4% of iron intake. Ninety-three percent of menstruating women had dietary iron intakes lower than recommended dietary allowances (RDA); 52.6% consumed less than two thirds of these RDA. In post-menopausal women and men, respectively 27.7% and 3.6% had dietary intakes lower than RDA. Serum ferritin was positively correlated with meat, ®sh and total iron intake, and negatively correlated with dietary products consumption, calcium and ®ber intake.

The iron status of a representative population sample in a district of Paris area (France) was assessed using a biochemical and dietary approach. Complete data were obtained for 1,108 subjects 6 months to 97 years old. Total iron intake increased up to adolescence and then remained stable in adult life. Iron intake was higher in men than in women. Most children and menstruating women presented a dietary iron intake below the recommended allowances. While anemia was not very common, iron deficiency (defined as the existence of at least two abnormal values in the four independent indicators of iron status: serum ferritin, erythrocyte protoporphyrin, transferrin saturation and MCV) was particularly common in infants, young children, menstruating women and elderly men. Serum ferritin, erythrocyte protoporphyrin and transferrin saturation were significantly correlated with inflammatory markers. Significant correlations were found between dietary total iron and serum ferritin (r = 0.29, p < 0.001) and hemoglobin (r = 0.44, p < 0.001). After adjustment for age, sex and inflammation, using multiple linear regression models, the relationship between both heme and nonheme iron intake and serum ferritin remained significant. Serum ferritin and hemoglobin levels were negatively correlated with calcium and phosphorus intake.

“…Most of the earlier studies used surrogate estimates of menstrual blood loss such as self-reported duration (Razagui et al 1991), frequency of menstruation (Worthington-Roberts et al 1988) or pre-or postmenopausal status (i.e. menstrual blood loss or no menstrual blood loss; Kenney, 1985;Bairati et al 1989;Yokoi et al 1994). The results are inconsistent: one study found no association between self-reported estimated blood loss and serum ferritin level (Bairati et al 1989), whereas another found a positive correlation (Kenney, 1985).…”

Impact of menstrual blood loss and diet on iron deficiency among women in the UK

Women of childbearing age are at risk of Fe deficiency if insufficient dietary Fe is available to replace menstrual and other Fe losses. Haem Fe represents 10 -15 % of dietary Fe intake in meat-rich diets but may contribute 40 % of the total absorbed Fe. The aim of the present study was to determine the relative effects of type of diet and menstrual Fe loss on Fe status in women. Ninety healthy premenopausal women were recruited according to their habitual diet: red meat, poultry/fish or lacto-ovo-vegetarian. Intake of Fe was determined by analysing 7 d duplicate diets, and menstrual Fe loss was measured using the alkaline haematin method. A substantial proportion of women (60 % red meat, 40 % lacto-ovo-vegetarian, 20 % poultry/fish) had low Fe stores (serum ferritin ,10 mg/l), but the median serum ferritin concentration was significantly lower in the red meat group (6·8 mg/l (interquartile range 3·3, 16·25)) than in the poultry/fish group (17·5 mg/l (interquartile range 11·3, 22·4) (P,0·01). The mean and standard deviation of dietary Fe intake were significantly different between the groups (P¼ 0·025); the red meat group had a significantly lower intake (10·9 (SD 4·3) mg/d) than the lacto-ovo-vegetarians (14·5 (SD 5·5) mg/d), whereas that of the poultry/fish group (12·8 (SD 5·1) mg/d) was not significantly different from the other groups. There was no relationship between total Fe intake and Fe status, but menstrual Fe loss (P¼ 0·001) and dietary group (P¼ 0·040) were significant predictors of Fe status: poultry/fish diets were associated with higher Fe stores than lacto-ovo-vegetarian diets. Identifying individuals with high menstrual losses should be a key component of strategies to prevent Fe deficiency.
