Nutrient intake and iron status of Australian male vegetarians.
Eur J Clin Nutr 1999; 53(3):189-94EJ

Abstract

OBJECTIVE

The study was designed to investigate the iron intake and status of Australian, male vegetarians aged between 20 and 50 y.

DESIGN

Cross-sectional comparison of male vegetarians and age/sex matched omnivores.

SETTING

Free-living community subjects.

SUBJECTS

39 ovolactovegetarians, 10 vegans and 25 omnivores were recruited by local advertisement.

OUTCOME MEASURES

A 12-d semiquantitative dietary record to assess iron and zinc intake. Iron status was assessed by measurement of serum ferritin and haemoglobin concentrations.

RESULTS

Mean (s.d.) daily iron intakes of both the ovolactovegetarians (20.4 (7.7) mg/d) and vegans (22.9 (6.2) mg/d), were significantly higher than the omnivores' intake of 15.8 (4.5) mg/d. Ovo-lactovegetarians and vegans had significantly (P < 0.001 and P < 0.05, respectively) lower serum ferritin concentrations than omnivores: mean (s.d.): 64 (46.9), 65 (49.9) and 121 (72.5) ng/ml, respectively. Significantly more ovolactovegetarians and vegans than omnivores had serum ferritin concentrations below 25 ng/ml and below 12 ng/ml (P < 0.05). A higher proportion of omnivores had concentrations above 200 ng/ml (P < 0.05). The differences in serum ferritin concentrations between the vegetarians and omnivores remained significant even after exclusion of iron supplement users.

CONCLUSION

Australian male vegetarians had iron intakes higher than those of omnivores and above recommended levels, but their iron status was significantly lower.
