Iron status among vegetarians is likely a result of several factors:
1) The bulk of iron consumed by vegetarians is in its less bioavailable form, non-heme iron.
2) Plant foods contain potent iron-absorption inhibitors, including phytates, oxalates, and phenolic compounds.
3) Although iron intake among vegetarians is often higher than among non-vegetarians, iron requirements for vegetarians is about 1.8 times higher compared to non-vegetarians. Thus, iron intake among vegetarians falls short of their needs.
Although vitamin C enhances iron absorption, relatively high intake of vitamin C among vegetarians does not guarantee adequate iron status. It would be prudent for vegetarians to utilize iron-fortified products. They may also benefit from periodic use of iron supplements.
