Two groups of 12 male weanling Sprague-Dawley rats received a
control diet or a diet with 10% Na-alginate, at the expense of corn
starch, for 8 days. A marked increase in faecal dry matter was seen
in the alginate group. Ca and Zn absorption were not affected by
alginate. Absorption of Fe, Cr, and Co were significantly reduced in
the alginate group (Harmut-Hoene & Schelenz, 1980)
