Effectivement votre médecin à raison : les phyates réduisent l'absorption du zinc & sont donc déconseillés

Phytates—which are present in whole-grain breads, cereals, legumes, and other foods—bind zinc and inhibit its absorption [[URL="http://ods.od.nih.gov/factsheets/zinc-HealthProfessional/#en2"]2[/URL],[URL="http://ods.od.nih.gov/factsheets/zinc-HealthProfessional/#en12"]12[/URL],[URL="http://ods.od.nih.gov/factsheets/zinc-HealthProfessional/#en13"]13[/URL]].
