Effects of High-Fiber Diets and Macronutrient Substitution on Bloating: Findings From the OmniHeart Trial.

ABSTRACT:

Objectives

To examine the effects of high-fiber, isocaloric, macronutrient substitutions on bloating.

Methods

The OmniHeart study is a randomized 3-period crossover feeding trial conducted from April 2003 to June 2005. Participants were provided 3 isocaloric versions of high-fiber (∼30 g per 2,100 kcal) diet, each different in carbohydrate, protein, and unsaturated fat composition. Each feeding period lasted for 6 weeks with a 2- to 4-week washout period between diets. Participants reported the presence and severity of bloating at baseline (participants were eating their own diet) and at the end of each feeding period.
