Nettet13. aug. 2024 · Phytic acid, an abundant secondary metabolite of plant foods, chelates dietary iron, and limits its intestinal absorption. Since phytic acid also inhibits the zinc absorption, higher risk of zinc deficiency is expected in populations with high prevalence of anemia, stunting, and high phytate content of staple diets [2,5]. Nettet1. jul. 2024 · Absorption: altered stomach acidity or binding of a drug to another substance in the stomach can affect drug absorption. However, most absorption interactions occur in the small intestine, because of a change in intestinal blood flow or intestinal motility, or an alteration in the bacteria that reside in the intestine.
