Such_Saturation said:I think iron in liver is mostly "elemental" which is less dangerous and more easily blockable.
I believe you meant non-heme iron. Liver has about 13 percent heme and rest is
non-heme. I asked RP about it, there is a response in email advice section.
Non-heme iron is blocked by coffee but not the heme part. But, the absorption
of iron is increased when it is eaten with protein, which increases acid secretion.
Calcium blocks both heme and non-heme iron upto a certain intake.
Heme iron absorption is quite high,muscle meat has about 65 percent heme.
There are studies that measured iron level on very low non animal iron source and
on dairy based diet. It has to be really low to deplete iron storage.
