Protein and the Kidneys

An older post (from Mar.2011) worth re-posting, from Mark's Daily Apple:

Dear Mark,

I am studying to become a nurse and am taking my first nutrition class at a local college.  As one of our assignments we had to record everything we ate for an entire week.

After looking at my results my teacher was dumbfounded.  To make a long story short, my teacher told me that I should only be eating 38 grams of protein each day, and that any more than that could harm my kidneys.  I’ve been Primal for 2 years and am healthier than ever.  I am 5′ 2″ and and a very lean 105 pounds.  Should I be concerned?
