This study investigated the effect of a high-fibre and high-phytate diet on levels of zinc, copper and magnesium. The study lasted for 21 days and included eight healthy subjects who were given a diet of conventional foods that included 1 mmol phytic acid, 29 g dietary fiber, 140 mumol zinc, 13 mumol copper, and 9 mmol magnesium per 2,415 calories.
The study found:
(a) The subjects levels of zinc decreased by 7 mumol.
(b) The subjects levels of copper decreased by 5 mumol.
(c) The subjects levels of magnesium decreased by 3 mmol.
The study reveals that a fibre-rich diet is associated with a net loss of the nutrients zinc, copper and magnesium.
