Psyllium husk has long been recognized as an excellent means of getting more dietary fiber into a person’s diet due to its high fiber count in comparison to other grains. Oat bran, also a good source of fiber, has about five grams of fiber per a third of a cup. Psyllium husk, on the other hand, offers approximately 71 grams of fiber for that same third of a cup.
Recent interest in psyllium has arisen primarily due to its use as an ingredient in high-fiber breakfast cereals, which is claimed to be effective in reducing blood cholesterol levels in those who consume it. Several studies point to a cholesterol reduction attributed to a diet that includes dietary fiber such as psyllium. Research reported in The American Journal of Clinical Nutrition concludes that the use of soluble-fiber cereals is an effective and well-tolerated part of a prudent diet for the treatment of mild to moderate hypercholesterolemia. Research also indicates that psyllium incorporated into food products is more effective at reducing blood glucose response than use of a soluble-fiber supplement that is separate from the food.
