The Effect of Fructose on Blood Fats in Dialysis Patients and Healthy Volunteers

This study will evaluate how a common dietary sugar (fructose) raises blood fats (triglycerides). We will determine whether the production of fat from fructose is higher in dialysis patients compared to healthy volunteers. Dialysis patients have high levels of hormone-like substances called cytokines that may increase blood fats. The results will help set better guidelines for diets for the general population and patients with kidney disease who are at high risk for heart attack and stroke. There will be one or two outpatient screening visit(s) and a one-week (6 nights) stay at the Rockefeller University Hospital.
