Fiber should be an important part of your daily diet. Most doctors recommend at least 25 grams of fiber per day. It is best to get your fiber from foods but if that is a problem you may have to supplement. Some foods high in fiber are vegetables, fruits, whole grains and legumes. One of the easiest ways to get more fiber in your diet is to stop buying refined products which have almost all the fiber stripped out. Examples; don't buy white bread, buy whole-grain, don't buy white rice, buy brown rice, don't buy regular pastas, buy whole-grain, etc. It really isn't hard to get the proper amount of fiber in your diet. Your body needs fiber to work properly.
