| Abstract | This study was designed to evaluate a polyphenols-rich fruit-based functional beverage on blood pressure, serum and liver lipid profiles in vivo. Sixty spontaneously hypertensive rats were divided into five groups and were fed with a AIN-93G-diet as the normal control (NC), high cholesterol diet as atherogenic control (AC), and the AC diet with three different beverage dosages (0.5. X, 1. X, 2. X), where X is the equivalence of two portion sizes for an adult (X = 10. mL/kg. BW/day) after dose translation. Blood pressure was measured during weeks 2 and 4 using a tail-cuff method. Systolic blood pressures were lowered by the beverage at the supplementation of 1. X/2. X after 2. week but not after 4. week. The oral administration of the beverage at 1. X/2. X significantly lowered liver cholesterol and total and non-HDL-cholesterol levels in the serum. Thus, the newly formulated beverage possessed hypolipidaemic effects while showing inconsistent effect in lowering the blood pressure. © 2013 The Authors. |
