Effects of chromium or copper supplementation on plasma lipids, plasma glucose and serum insulin in adults over age fifty.

摘要

24 independently living volunteers with raised plasma total cholesterol, over 50 years of age, were randomly assigned to 8 weeks supplementation with either lactose as a placebo, Cr, or Cu. After 8 weeks of supplementation a significant decrease inplasma total cholesterol and LDL-cholesterol was observed in both the Cr and Cu supplemented groups. A significant decrease in plasma triglycerides was observed in the Cu supplemented group. Males in the Cr supplemented group had a significant decrease in plasma glucose and serum insulin, and females in the Cu supplemented group had a significant decrease in plasma glucose. These data suggest that adequate Cr and Cu intakes may have beneficial effects on lipids and glucose in adults over 50 years of age.
