What are the bio chemical problems of high in take of phosphorus above the reccomended nutrient intake (RNI) ?

Question

This is not referring to intake of supplements just in take from food. The RNI is set at 550 mg p'day and i would like to find out problems when going over the upper RNI limit of 1,100mg p'day
thanks

Answer 1

If you take in essentially any "phosphorus" in elemental form you'll die pretty quickly. I'm assuming you're talking about phosphate, in which case the answer is very simple: phosphates are not very soluble, and if your intake of them is too high you will form kidney stones. So don't drink too much soda.
