does iron interfere with calcium absorption in food?

THERE ARE SEVERAL RESEARCHES AND ARGUEMENTS related to absorption of minerals from food.  Its true that iron competes with calcium absorption but does not interfere. Also food preparations are a mixture of varied nutrients. Hence when speakung of a normal diet calcium absorption is not interfered by iron. Except when we take gelusil or such exexternal calcium sources iron absorption may be interfered. Otherwise milk helps in absorption of vitamins particularly vit a d e and k since these are lipid soluble.  Hence in short iron will only compete with calcium and not interfere.

Always synergistic effect only plays a role as far as food prep are concerned.
