Abstract

OBJECTIVE:

Evidence supports the role of dietary fiber in improving metabolic health. PolyGlycopleX (PGX), a viscous functional polysaccharide improves lipidemia and glycemia in healthy adults. Our objective was to examine the effects of PGX on risk factors associated with the metabolic syndrome in Japanese adults with abdominal obesity.

DESIGN AND METHODS:

Sixty four subjects assigned to 14 weeks of 15 g day(-1) of PGX or placebo were assessed in a randomized, double-blind, placebo-controlled, parallel group trial. At week 0 and 14, primary outcome measures were serum lipids, abdominal adiposity, glucose tolerance and blood pressure.

RESULTS:

Total and LDL cholesterol were reduced at week 14 with PGX but not placebo (P < 0.05). The reduction in waist circumference at week 14 was greater with PGX versus placebo (P < 0.05). In females, abdominal visceral fat was decreased to a greater extent with PGX versus placebo (P < 0.05). While glucose tolerance worsened with placebo over time, PGX reduced glucose total area under the curve from week 0 to 6 (P = 0.039). Serum concentrations of resistin and IL6 increased slightly in placebo and decreased slightly with PGX .

CONCLUSIONS:

PGX is a functional fiber that shows promise in reducing risk factors related to the metabolic syndrome in Japanese adults with abdominal obesity.
