The aim of the present work is to investigate the interrelationship between phytate and zinc in some Italian diets. Phytic acid and zinc content were determined and the phytate:zinc molar ratios calculated in 13 Italian diets. This ratio, rather than the values of phytate and zinc separately, allows a more correct understanding of the zinc availability in these diets. Only one diet, with a molar ratio of 11, indicates some risk of zinc deficiency. All other diets show a satisfactory phytate:zinc molar ratio.
