Study Details

Study Goal

The researchers aimed to determine whether pre-germinated brown rice (PGBR) could effectively treat metabolic syndrome by improving glucose and lipid metabolism in mice.

Results Summary

The study found that PGBR improved blood pressure, biochemical parameters, and protein expressions related to glucose and lipid metabolism in mice fed a high-fat diet, suggesting it may help treat metabolic syndrome.

Population

Mice fed a high-fat diet for 16 weeks.

Effective Dosage

Not specified (dietary carbohydrate replaced with PGBR).

Duration

4 weeks.

Interactions

None mentioned.

Abstract

To investigate using pre-germinated brown rice (PGBR) to treat metabolic syndrome, we fed one group of mice standard-regular-diet (SRD) for 20 weeks and another group of mice high-fat-diet (HFD) for 16 weeks. We subdivided them into HFD group and HFD + PGBR group whose dietary carbohydrate was replaced with PGBR for 4 weeks. The HFD group gained more weight, had higher blood pressure, heart rate, blood glucose and lipids, liver levels of TG, feces TG and bile acid, lower adipose levels of adipocytokine, lower skeletal muscle IR, IRS-1, IRS-2, PI3 K, Akt/PKB, GLUT-1, GLUT-4, GCK and PPAR-γ; higher liver SREBP-1, SCD-1, FAS, HMGCR, LDLR, CYP7α1 and PPAR-α, and higher adipose SREBP-1, SCD-1, FAS, and lower adipose PPAR-α and adiponectin. The HFD + PGBR group had clearly improved blood pressure, biochemical parameters and above proteins expressions. PGBR successful treatment of metabolic syndrome was achieved through improvements in glucose and lipid synthesis and metabolism.
