Viscous versus nonviscous soluble fiber supplements: Mechanisms and evidence for fiber-specific health benefits.
Summary of "Viscous versus nonviscous soluble fiber supplements: Mechanisms and evidence for fiber-specific health benefits."
Purpose: This review focuses on the health benefits of viscous versus nonviscous soluble fibers, why symptoms can occur with increased fiber consumption, and how to avoid symptoms to improve adherence with a high-fiber diet. Data sources: Review of scientific literature as well as evidence-based guidelines and resources. Conclusions: While it is generally known that "fiber is good for you," it is less well known that specific health benefits are associated with specific fiber characteristics. Many of the health benefits of fiber can be directly correlated with the viscosity of soluble fibers when hydrated (i.e., gel-forming). A reduction in viscosity of a given fiber will attenuate these health benefits, and a nonviscous fiber does not exhibit these health benefits. Implications for practice: 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).

Medical and Biotech [MESH] Definitions
Cotton Fiber
A TEXTILE fiber obtained from the pappus (outside the SEEDS) of cotton plant (GOSSYPIUM). Inhalation of cotton fiber dust over a prolonged period can result in BYSSINOSIS.
Prejudice
A preconceived judgment made without adequate evidence and not easily alterable by presentation of contrary evidence.
Beta-glucans
Glucose polymers consisting of a backbone of beta(1->3)-linked beta-D-glucopyranosyl units with beta(1->6) linked side chains of various lengths. They are a major component of the CELL WALL of organisms and of soluble DIETARY FIBER.
Angioplasty, Balloon, Laser-assisted
Techniques using laser energy in combination with a balloon catheter to perform angioplasty. These procedures can take several forms including: 1, laser fiber delivering the energy while the inflated balloon centers the fiber and occludes the blood flow; 2, balloon angioplasty immediately following laser angioplasty; or 3, laser energy transmitted through angioplasty balloons that contain an internal fiber.
Evidence-based Nursing
A way of providing nursing care that is guided by the integration of the best available scientific knowledge with nursing expertise. This approach requires nurses to critically assess relevant scientific data or research evidence, and to implement high-quality interventions for their nursing practice.
