The Study
High-protein diet with renal hyperfiltration is associated with rapid decline rate of renal function: a community-based prospective cohort study.
This study is like noticing that people who eat lots of protein and have fast-working kidneys also tend to have their kidneys get worse faster. It shows a link, but it can't prove that the protein causes the problem because other things might be involved.
