Fiber complex and psyllium may increase the “good” cholesterol levels

Studies have found high-fiber diets reduce chances for several chronic diseases. In this study, 93 overweight or obese men and women, ages 19 to 68, took 5 grams of a viscous fiber complex (glucomannan, sodium alginate and xanthan gum), psyllium, or a placebo before meals. All participants maintained their usual diet and lifestyle over the 12-month study period. At three months, compared to placebo, both fiber groups had significantly lower insulin levels, less insulin resistance, lower total cholesterol levels, and lower LDL cholesterol levels. Glucose levels were also lower in the fiber complex group.

Most of these improvements continued through six months, and by 12 months, those in the fiber complex group also saw HDL— the “good” cholesterol—levels increase significantly compared to placebo. Discussing the findings, doctors said that adding dietary fiber to the diet, without having to change an existing dietary pattern, may help maintain healthy glucose and insulin levels and improve lipids.
