Soluble fiber from foods such as psyllium seed husks, as part of a diet low in saturated fat and cholesterol, may reduce the risk of heart disease. A serving of Psyllium Husk Powder supplies 6 grams of the 7 grams soluble fiber necessary per day to have this effect. Vigorously mix 1 level tablespoon daily into at least 12 oz. of water or juice and consume immediately. Be sure to drink plenty of additional fluids throughout the day. Start with smaller amounts and gradually increase over several weeks.
