In bread-based diets fed to rats for 6 weeks, increasing the level of phytate in diets otherwise identical in protein, calcium, iron, phosphorus, and vitamin D content did not appear to interfere substantially with the availability of iron naturally occurring in wheat. The availability of phytate phosphorus was also not affected appreciably. No relationship, in a quantitative sense, was observed between intestinal phytase activity and iron or phytate availability.
