Can drinking too much soda affect iron levels?

I have seen reports: that it can, although I am not sure of the mechanism, but it has to be a LOT of soda. The major problem with lots of soda is the calories, and it is a major contributor to the epidemic of overweight, obese and diabetic individuals in the US and western world. It appears to reduce iron absorption in some people. You are far better off with water which is cheaper, healthier and doesn't affect iron.
