Phytate Iron Absorption Block
Phytates in grains and legumes can block non heme iron absorption—use soaking, fermentation, and vitamin C pairing rather than dropping plant staples.
Phytate iron absorption block happens when phytic acid in whole grains, legumes, nuts, and seeds binds minerals—including non heme iron and zinc—reducing uptake in the same meal. Soaking, sprouting, fermenting tempeh, and varied cooking methods lower phytate somewhat.
Do not abandon legumes; pair iron foods with vitamin C and space high-calcium supplements.
Common questions
-
Should vegans avoid phytate-rich foods?
No—legumes and whole grains are core protein and iron sources. Improve absorption with vitamin C, varied prep, and clinician-guided supplements when ferritin is low.
