Metabolic Effects of Short Term Sugarcane Bagasse Supplementation

Overview

The purpose of this study is to help understand the benefits of eating food supplemented with fiber in the form of sugarcane bagasse (the leftover fiber after cane juice is extracted) on glucose metabolism and body weight.

Study Type

  • Study Type: Interventional
  • Study Design
    • Allocation: Randomized
    • Intervention Model: Parallel Assignment
    • Masking: Double (Participant, Investigator)
  • Study Primary Completion Date: January 2014

Detailed Description

The investigators will employ a double-blind randomized controlled study design with 3 arms such that obese, insulin resistant adults will be randomly selected to receive food made with 1) sugarcane bagasse, 2) non-caloric, non-fermentable fiber, or 3) a similar product with minimal fiber for 4 weeks. The intervention will be in the form of brownies and cookies and will look and taste nearly identical to each other. Caloric value will be constant with all three delivery systems. Subjects will have blood testing and body composition analysis before and after the intervention.

Interventions

  • Other: Sugarcane bagasse
    • One brownie containing 10 g of sugarcane bagasse and 2 cookies containing 3 g of sugarcane bagasse (total of 13 g of sugarcane bagasse per day)
  • Other: Non-caloric, non-fermentable fiber
    • One brownie containing 10 g of fiber and 2 cookies containing 3 g of fiber (total of 13 g of non-caloric, non-fermentable fiber per day)
  • Other: Minimal fiber
    • One brownie containing 3g of fiber and two cookies containing 1g of fiber (total of 4 g of dietary fiber per day)

Arms, Groups and Cohorts

  • Experimental: Sugarcane bagasse
    • 10 subjects will consume food (brownies and cookies) made with 13 g of sugarcane bagasse everyday for 4 weeks
  • Active Comparator: Non-caloric, non-fermentable fiber
    • 10 subjects will consume food (brownies and cookies) made with 13 g of non caloric, non-fermentable fiber everyday for 4 weeks
  • Placebo Comparator: Minimal fiber
    • 10 subjects will consume food (brownies and cookies) made with 4 g of dietary fiber everyday for 4 weeks

Clinical Trial Outcome Measures

Primary Measures

  • The benefit of sugarcane bagasse on glucose tolerance and insulin resistance in adults with established insulin resistance
    • Time Frame: 4 weeks
    • Participants will be randomly selected to eat food supplemented with either 1) sugarcane bagasse, 2) another type of fiber of equal weight, or 3) minimal fiber. At baseline each eligible subject will have a 3 hour oral glucose tolerance test. Subjects will consume one brownie and two cookies a day for four weeks. At the end of four weeks, the blood tests conducted at baseline will be repeated.

Secondary Measures

  • The effect of sugarcane bagasse on body weight/composition
    • Time Frame: 4 weeks
    • At baseline and weekly till the end of the study, weight will be measured. In addition body composition via DXA will be measured at baseline and at the end of the study.
