A lactose-free diet means eating foods that do not contain lactose- a sugar that is found in most milk products. Some people cannot properly break down lactose or makes lactose that does not work properly. Some can eat small amounts of lactose without having symptoms, while others have to avoid it completely. 

Low Lactose Diet- Generally eliminates only milk and cow products. However, some can tolerate milk in small amounts (2 oz) throughout the day or as part of a meal. Some can tolerate small amounts of yogurt. These patients can experiment to find a level of lactose they can tolerate. It is generally better tolerated with a meal than by itself. Some people can build up their tolerance by gradually introducing lactose-contained foods.

Lactose-Free Diet– All lactose products must be eliminated, including foods that are prepared with milk, both at home and in commercially packaged foods. These people may be able to use 100% lactose-free milk or soy milk. Labels should always be read carefully.

Lactose Digestive Aids and Products- Many people can drink milk in which the lactose has been partially or completely broken down. 

A low fiber or low residue diet limits the consumption of dietary fiber, oftentimes by placing restrictions on foods found to have high amounts, including certain fruits, vegetables, dairy, and whole-grain products. This diet reduces stool size and frequency, particularly helping those suffering from flare-ups caused by Inflammatory Bowel Disease as it relieves the intestines from working as hard.

Low Fiber-Low Residue Diet (4-10 Grams Fiber)

Dietary fiber is the undigestible part of plants that maintains the structure of the plant. Dietary fiber includes cellulose, hemicel­lulose, polysaccharides, pectins, gums, mucilages, and lignins. Although they are chemically unrelated, they all resist digestion by the human body. It is this resistance that makes these fibers important in both the nor­mal functioning and in disorders of the large intestine or colon.

In certain medical conditions, it is important to restrict fiber. These include acute or subacute diverticulitis and the acute phas­es of certain inflammatory condi­tions of the bowel-ulcerative colitis or Crohn’s disease. After some types of intestinal surgery, a low fiber, low residue diet may be used as a transition to a regular diet. A low-fiber diet may also be used for a period of time after a colostomy or ileostomy is performed.

Nutrition Facts

Depending upon individual food selection, the Low Fiber, Low Residue Diet is adequate in all nutrients (National Research Council’s Recommended Dietary Allowance). If the diet must be strict and followed over a long period of time, the intake of fruits and vegetables may not be adequate, and/or on a low residue diet, there may not be enough calcium included. In these cases, a multivitamin supplement or liquid nutritional supplement may be needed.

Special Considerations

If a low fiber or low residue diet results in abdominal cramps or discomfort, notify the dietitian or physician immediately.

Various functions along the path of digestion contribute to the production of gas and flatulence. A certain degree of gas or flatulence is normal. However, there are many factors which can contribute to excess gas and flatulence. Following simple diet and lifestyle changes can help to reduce gastrointestinal gas and relieve symptoms.

It is recommended that foods which contribute to gas production, such as legumes, milk and milk products, certain vegetables, root vegetables, certain fruits, wheat-based cereals and breads, fatty foods, and carbonated beverages be avoided.

It can also be helpful to eat slowly and avoid the following:

• smoking pipes, cigarettes, or cigars
• chewing gum or hard candy
• sipping through narrow straws or bottles
• deliberately swallowing air to force a belch
