Effect of potato ethanol residue on rat plasma cholesterol levels.

We investigated the cholesterol-lowering effect of a potato ethanol residue (PER). The plasma cholesterol levels excluding high-density lipoprotein cholesterol were lower in the rats given a PER-containing diet for 6 weeks than in the control group, whereas the fecal cholesterol levels were higher. These results suggest that PER partially reduced plasma cholesterol levels via excretion of cholesterol into the feces.
