Mineral intake and blood levels in vegetarians.
Concern has been raised that a long-term high-fiber diet may lead to mineral deficiencies. In this study, mineral intake and blood levels were investigated in 92 ovolacto vegetarians and 113 omnivores. The intake of iron, zinc, calcium and magnesium was adequate in both groups. The intake of iron and magnesium was significantly higher in the vegetarians. Mean blood levels of iron, iron binding capacity, calcium, phosphorus, alkaline phosphatase, zinc and magnesium were within normal limits in both groups. Serum magnesium levels were significantly higher in male vegetarians. Iron binding capacity was significantly lower in vegetarians of both sexes. It is concluded that a long-term ovolacto vegetarian diet does not lead to mineral deficiencies.
