Nutriceuticals in cardiovascular disease: psyllium

Area of Science:

• Nutrition Science
• Cardiovascular Health
• Gastroenterology

Background:

• Western diets often lack sufficient dietary fiber, potentially contributing to chronic diseases.
• Fiber intake is increasingly recognized for its role in disease prevention and health maintenance.
• A decline in coronary artery disease (CAD) mortality may be linked to increased awareness of fiber's benefits.

Purpose of the Study:

• To evaluate the role of psyllium, a soluble fiber, in managing hypercholesterolemia.
• To assess psyllium's efficacy as an adjunct to dietary and pharmacological interventions for cholesterol reduction.

Main Methods:

• Psyllium's mechanism of action involves binding to bile acids in the gut, inhibiting their reabsorption.
• Psyllium is studied as a component of American Heart Association (AHA) step 1 or step 2 diets.
• Investigated psyllium's combined effects with other cholesterol-lowering medications, such as statins.

Main Results:

• Psyllium acts similarly to bile acid sequestrant drugs by binding bile acids.
• It is effective as a supplementary treatment for mild-to-moderate hypercholesterolemia.
• When combined with statins, psyllium offers additional cholesterol-lowering benefits.

Conclusions:

• Psyllium is a well-tolerated and cost-effective soluble fiber for managing hypercholesterolemia.
• It serves as a valuable adjunct to both dietary modifications and cholesterol-lowering drug therapies.
• Increasing fiber intake, specifically psyllium, may play a significant role in cardiovascular disease prevention.
