High-Protein Diet Linked to Kidney Problems!

A Spanish study found that rats fed a long-term, high-protein diet (57% of total calories from protein) had a higher risk for developing kidney stones and other renal diseases than rats fed a lower protein diet (13% of total calories from protein). The authors of the study stress that even though these results are derived from rat subjects, their findings should translate to humans and anyone on a high-protein diet should be closely monitored for kidney-related issues.
