What foods lower clearitine levels to a normal level?

None: Think you meant creatine level. It is a marker of how well the kidney functions by how it lets out the muscle waste product (/building block). Old school said low-protein diet could help ease workload of kidney and might lower creatine (some), but if more than a few 1/10s of a point, not likely to be done by diet. Can potentially slow progression of disease. Can consult dietitian for advice.

Not usual : your blood creatinine is a measure of your kidneys efficacy. Diet should not impact blood levels unless you take dietary supplements that contains creatine. If you have high creatinine then you should see a kidney doctor.
