Further study details as provided by Wael Jaber, The Cleveland Clinic:

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 ]

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 ]

Enrollment: 50
Actual Study Start Date: January 2008
Study Completion Date: July 2013
Primary Completion Date: July 2011 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Experimental: High Fiber Intake
Two 3/4 Cup servings of high fiber Uncle Sam cereal daily
Dietary Supplement: Uncle Sam Cereal
two 3/4 cup servings daily of Uncle Sam Cereal dietary instruction on high fiber diet

Detailed Description:
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.
