does calcium affect iron absorb
There is some evidence to support the impact of calcium on iron absorption, albeit from short-term studies focused on this interaction with single meals. On the other hand, long-term studies have found that calcium and milk products donât have any adverse effect on iron absorption. Unfortunately this isnât a simple case of yes or no â hence the controversy! The actual mechanism of the interaction of calcium and iron absorption is not well understood. The general consensus is that calcium can interfere with iron absorption on a short term basis.
