Why was this study done?

There is a well-established relationship between fiber intake and cholesterol levels. Many of the studies performed, though, have been short-term in nature. This study was designed to assess the effectiveness and feasibility of long-term (six months) supplemental fiber.

What did the study find?

A mixture containing water-soluble dietary fiber (psyllium, pectin, guar gum, and locust bean gum) was successful at reducing both LDL and total cholesterol levels during six mouths of supplementation.
