People who are used to eating fiber have no difficulty with increasing their fiber but intestines that aren’t used to digesting the products they are supposed to may increase the amount of gas produced until the body is able to manufacture enough of the right enzymes to completely digest the food. This is a natural process and high fiber should NOT be stopped just because you have a bit of gas.
Drink plenty of fluids during the day. Most individuals should drink between 7 to 9 eight ounce glasses of water each day unless they live in a hot climate and should then drink more. Fluids help to keep the stool soft and the body from retaining water.
