Effects of Hi-maize Resistant Starch on Insulin Sensitivity

This study has been completed.

Last verified: September 2010
The purpose of this study is to determine the effects of a dietary fiber, resistant starch, on insulin sensitivity. Low insulin sensitivity is a risk factor for some diseases including type 2 diabetes and heart disease. This study will show if consuming resistant starch can help improve insulin sensitivity in overweight and obese people.

Study Type: Interventional
Study Design: Allocation: Randomized
Intervention Model: Crossover Assignment
Masking: Quadruple (Participant, Care Provider, Investigator, Outcomes Assessor)
Primary Purpose: Prevention
Official Title: A Randomized, Controlled, Double-blind Crossover Study to Assess the Effects of a Dietary Fiber Ingredient, at Two Doses, on Insulin Sensitivity
