“…Twenty-eight per cent of vegetarians had serum ferritin levels below 25 ngaml, which may indicate the beginning of iron storage depletion (Bothwell et al, 1979). Furthermore, one ovolactovegetarian and two vegans had serum ferritin concentrations below 12 ngaml, indicating depletion of storage iron (Cook et al, 1992). Although these subjects' haemoglobin levels were in the normal range, these storage levels might prove insuf®cient to provide for periods of stress or an episode of blood loss, and continued low availability of iron may result in iron de®ciency.…”

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 ageasex 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) mgad) and vegans (22.9 (6.2) mgad), were signi®cantly higher than the omnivores' intake of 15.8 (4.5) mgad. Ovo-lactovegetarians and vegans had signi®cantly (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) ngaml, respectively. Signi®cantly more ovolactovegetarians and vegans than omnivores had serum ferritin concentrations below 25 ngaml and below 12 ngaml (P`0.05). A higher proportion of omnivores had concentrations above 200 ngaml (P`0.05). The differences in serum ferritin concentrations between the vegetarians and omnivores remained signi®cant 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 signi®cantly lower.

“…The within-run and between-run coefficients of variation were 4 and 12%, respectively. Values below 12 m g/L were considered to reflect depleted iron stores (Cook et al, 1992). For zinc the analysis was done after dilution 1:4 with deionized distilled water by atomic absorption spectrophotometry (Perkin Elmer Model 360, Perkin Elmer, Norwalk, CT, USA).…”

Objectives:To assess the effect of zinc supplementation on growth and body composition among schoolchildren. Design: Randomized, double-blind, placebo-controlled trial. Setting and Subjects: 313 rural Zimbabwean schoolchildren (144 boys and 169 girls), 11-17 y). Interventions: Supplementation with zinc (30 or 50 mg) or placebo on schooldays for 12 months. Due to drought, a food programme was in operation during the last eight months of the study. Variables: Weight, height, upper arm circumference, triceps skinfold thickness, and weight-for-age, height-forage, weight-for-height, arm muscle-area-for-age and arm fat-area-for-age Z-scores. Results: Significant effects on weight gain (0.51 vs 0.14 kg, P 0.01), weight-for-age Z (70.08 vs 7 0.14, P 0.01) and arm muscle area-for-age Z-score (0.10 vs 0.01, P 0.03) were seen over the first three months, whereas no effects were seen over the full 12 months. Conclusions: Zinc deficiency impairing lean body mass and weight gain was documented. However, the effect of zinc seen over the first three months vanished during the last nine months when the food programme was in operation. Zinc deficiency may have persisted, but another nutrient may have become growth limiting during the last nine months.
