(HealthDayNews) -- Many doctors push fiber as an essential part of a patient's diet. Because it retains water, fiber helps food pass through your digestive system faster, causing a laxative effect. It can also help lower your cholesterol.
But how much fiber is enough? The American Dietetic Association recommends between 20 and 35 grams a day. Generally, if a product contains 3 grams of fiber per 100-gram serving, it's a good source. Some fiber-rich foods include flaxseed, fruit, oats, barley and beans.
