Second Prize: The cholesterol and glucose lowering effect of brown rice on hypercholesterolemic Filipino adults

Title: The cholesterol and glucose lowering effects of brown rice among hypercholesterolemic Filipino adults

Author(s): Maureen Sarmago, RND, MSCN

Institution where study was conducted: Philippine Women's University, Manila, Philippines

Background: Several human trials have shown the brown rice intake can help lower blood cholesterol and fasting blood glucose.

Objective: To examine the effect of brown rice on cholesterol and fasting blood glucose compared to white rice.

Methodology: In this randomized parallel study thirty eight (38) hypercholesterolemic adults were randomized to the brown rice (BR) group (n=18) and to the white rice (WR) group (n=20). The participants consumed brown or white rice for 12 weeks. Total cholesterol, high-density lipoprotein (HDL-C), low-density lipoprotein (LDL-C) and fasting blood glucose levels were measured before and after the intervention. Changes in the cholesterol and fasting blood glucose level were compared within and between groups.

Results: In the BR group, total cholesterol decreased significantly (p< 0.01) by 7.09% with an increase of 5.4% in HDL-C, which was not statistically significant. The fasting blood glucose was significantly reduced (4.2%, p<0.01). In the WR group, reduction in cholesterol and blood glucose were not significant, but their HDL-C improved significantly (8.85%, p<0.01). An unexpected significant increased in LDL cholesterol was observed in the BR group (8.1%, p=0.01) and WR group (9.96%, p=0.01) respectively.

Conclusion: This study suggests that brown rice consumption may help lower cholesterol and fasting blood glucose, and may be beneficial in the prevention and management of cardiovascular disease and other lifestyle related disorders.
