A Randomized Controlled Trial of High Dietary Fiber Intake on Serum Lipids - Full Text View

Sponsor:	The Cleveland Clinic
Collaborator:	US Mills, LLC
Information provided by:	The Cleveland Clinic
ClinicalTrials.gov Identifier:	NCT00593632

Purpose

Dietary fiber intake has been shown to have modest effect in lowering cholesterol. However, most of these studies were done with 20g/daily fiber intake. Not much is known about high dietary fiber intake (30-40 g/day) and serum cholesterol. Also, there have been small studies that have shown modest decrease in oxidative stress by increasing dietary fiber intake. The goal of our study is to determine the efficacy /safety of high dietary fiber intake in raising HDL, lowering LDL, and lowering oxidative stress in patients with hyperlipidemia.

Primary Outcome Measures:

To test whether 30-40g of daily dietary fiber increases HDL, lowers total cholesterol and LDL levels in patients at 12 weeks [ Time Frame: 12 weeks ] [ Designated as safety issue: No ]

Secondary Outcome Measures:

To test whether Lipoprotein (a), triglyceride level, LDL: HDL ratio, fibrinogen, CRP, Urine f1 2 isoprostane and body weight will be lowered in patients after 12weeks. [ Time Frame: 12 weeks ] [ Designated as safety issue: No ]

Estimated Enrollment:	60

Estimated Primary Completion Date:	October 2011 (Final data collection date for primary outcome measure)

Arms	Assigned Interventions
Active Comparator: A Arm is dispensed two 3/4 cup servings of Uncle Sam cereal daily in conjunction with high fiber dietary teaching	Dietary Supplement: Uncle Sam Cereal two 3/4 cup servings daily of Uncle Sam Cereal dietary instruction on high fiber diet
