Many of the health benefits of fiber can be directly correlated with the viscosity of soluble fibers when hydrated (i.e., gel\u2010forming). A reduction in viscosity of a given fiber will attenuate these health benefits, and a nonviscous fiber does not exhibit these health benefits.<\/jats:p><jats:p><jats:bold>Implications for practice:<\/jats:bold> Increasing the viscosity of chyme with a viscous soluble fiber has been shown clinically to lower cholesterol for cardiovascular health, improve glycemic control in type 2 diabetes, normalize stool form in both constipation (softens hard stool) and diarrhea (firms loose\/liquid stool), and improve the objective clinical measures of metabolic syndrome (glycemic control, lipoprotein profile, body mass index\/weight loss, and blood pressure).<\/jats:p><jats:p><jats:bold>Disclosures:<\/jats:bold>\u2002\u2028Johnson McRorie is a Clinical Scientist with Procter &amp; Gamble, which markets two fiber products.
