Abstract

People who frequently consume whole grains show a lower incidence of arteriosclerotic disease than people who consume primarily refined grains. We examined whether or not rice bran extract containing the acylated steryl glucosides (ASG) fraction decreases blood LDL cholesterol levels in obese Japanese men with high blood levels of LDL cholesterol. The study utilized a randomized, double-blind design. A total of 51 subjects were randomly allocated to either a rice bran extract containing ASG fraction (RB-ASG) group or a placebo group. Subjects in the RB-ASG group received 30-50 mg/day of RB-ASG, and the placebo group took 9 capsules/day for 12 weeks. Before and after intake, height, weight, body fat percentage, systolic and diastolic blood pressure were measured, blood was collected, and visceral fat area, subcutaneous fat area, and abdominal circumference were determined based on umbilical computed tomography. Percentage decreases in blood LDL cholesterol, non-HDL cholesterol, LDL/HDL ratio, abdominal circumference and subcutaneous fat area were significantly better in the RB-ASG group than in the placebo group. These findings suggest that RB-ASG fraction may reduce blood LDL cholesterol levels and the risk of arteriosclerosis in obese Japanese men with high LDL cholesterol levels. J. Med.
