Researchers from the University of Florida, led by Michael Gersch, M.D., discovered that after six weeks, rats on a high-fructose diet (60%) had significantly larger kidneys and more kidney malfunction than did two other groups of rats -- one fed 60% dextrose and another fed a standard rat diet (whatever that might be).
Interestingly, dextrose didn't seem to cause the same problems, but I wouldn't take that as an endorsement to indulge in all the dextrose you want, though. The study was small ~ the scientists examined three groups of 14 male rats - its findings are certainly notable. The researchers discovered the kidney damage after six weeks, when they removed part of the rats' kidneys.
