as I understand it, as the degree of acidity in foods increases , iron absorption increases. Conversely as the acidity decreases, the iron in the food is absorbed less efficiently.
Some nutrients work against one anothers absorption.
this is sometimes called an "antagonistic" relationship.
iron inhibits the absorption of vit E
Vit C ( ascorbic acid) increases the absorption of iron... due to it's acidity.
iron is vital to the blood carrying oxygen so we need it. It also can be taken in excessively. Ongoing studies for a # of years have been showing a correlation between high iron levels in the blood and increased risk of heart disease. It is One factor among several.

Well -- what is the rest of the story???
And "Tea" - black tea, green tea, herbal tea, chinese medicine tea --
are the effects on iron absorption the same for all tea?
