2 Today s Objectives Understand the importance of diet and nutrition in inflammatory bowel disease (IBD) Review the effects of IBD on nutritional state Outline dietary strategies that are helpful in controlling IBD symptoms Review what type of diet is best during a flare Identify key elements of nutrition support therapy Discuss alternative nutritional therapies Answer questions

3 Nutrition for the IBD Patient: Nutritional Goals are the same for both Crohn s and Ulcerative Colitis. Goal: Reduce inflammation and bowel irritation through nutritionally rich foods that nourish and heal the bowel.

4 Importance of Diet & Nutrition Diet and nutrition are important parts of IBD management Diet is the actual food that is consumed Nutrition refers to properly absorbing food and staying healthy Incorporating good nutrition into your diet is essential

5 According to the Crohn s and Colitis Foundation of America: Food does not cause IBD to develop or worsen inflammation, but some foods may aggravate the symptoms of IBD.

6 Complications: Nutrient deficiencies due to malabsorption. Strictures of the bowel leading to need for very soft or liquid diet. Dehydration. Weight loss. Need for surgery/ostomies.

7 Nutritional Deficiencies: IBD is associated with decreased digestion and malabsorption of carbohydrates, protein, fat, water, and a variety of vitamins and minerals. Limited diet and low appetite can also lead to poor nutrition. Most common deficiencies: - Vitamin B12 - calcium - Vitamin D - iron - protein - folate/zinc

8 Effects of IBD on Digestion/Absorption Crohn s Disease: -Inflammation or surgical resection of small intestine makes patients less able to absorb nutrients. -Malabsorption of micro nutrients, protein, fat, carbohydrate, fat soluble vitamins A,D,E,K can occur. -Incompletely digested foods that travel through the colon may also cause diarrhea. -Diarrhea and loss of appetite also contribute to nutrient deficiencies.

9 Cont Ulcerative Colitis: -Inflammation of large intestine causes poor water absorption and diarrhea with possible electrolyte imbalances and decreased vitamin K production. -Blood loss may be severe and iron deficiency anemia is common. -Small intestine works normally. However since diarrhea can be rapid and severe small intestine may not have time to absorb nutrients from food.

11 Vitamin/Mineral Supplementation: Multivitamin/mineral recommended. Calcium mg daily. (Steroids increase needs). Vitamin D IU daily. Vitamin B mcg monthly injection (Crohn s ileal disease). Iron 325mg 1-3 times daily. (If anemia present). Folic acid 1000micrograms daily (as needed).

12 Diet and IBD Good nutrition is important to help restore and maintain good health. Diet can help reduce symptoms while the disease is being treated in other ways i.e. medications, surgery. NO one single diet is right for all IBD patients. Research on special diets is limited. Diet should be tailored individually to meet patient nutritional needs, food preferences, and lifestyle.

13 Diet recommendations vary according to: Type of disease - Crohn s vs. UC Part of GI tract affected Presence of strictures Disease state remission vs. flare. Weight loss Anorexia -Important to work with a Registered Dietitian that can complete thorough clinical assessment of nutritional parameters, lifestyle, diet preferences, and nutrient requirements.

14 Complete nutritional assessment, H&P, anthropometrics, lab values, medications, diet history. Estimate caloric needs. BEE Estimate protein needs: (RDA.8 grams per kg) IBD patient: g/kg

15 Diet during a flare: Eat smaller meals more often. Four to six small meals may be easier for the intestines than two to three large ones. Food choices should be low in fiber. High in protein. If stricture present avoid nuts, seeds, corn, popcorn, stringy vegetables. (approx. 2/3 of CD pts w/ small bowel disease). Restrict fat if fat malabsorption present (approx. 1/3 of CD pts) Elimination Diet or Liquid Diet as needed.

16 Foods that may worsen symptoms: Lactose and dairy products: - If lactose intolerant limit the intake of foods like milk, ice cream, cheese, and yogurt. -Try lactase fortified products like Lactaid brand milk or take lactase enzymes prior to meal containing lactose. - Use other calcium fortified foods to increase calcium intake such as fortified soy or rice milk, fortified fruit juices. - A calcium supplement with vitamin D may be prescribed.

17 Greasy or fatty foods: - May cause diarrhea, gas, or nausea, or fat malabsorption. - Limit intake of butter, margarine, cream sauces, cheeses, pastries, fried foods, and high fat cuts of meat such as bacon, sausage, or ribs.

18 Limit caffeine containing products: Coffee, tea, and soft drinks. -Caffeine is known to be irritating to the intestinal tract. It can stimulate the colon to contract and may promote more frequent bowel movements. - Tannic acid found in decaffeinated coffee and tea can also irritate the intestines.

19 Limit intake of Alcohol: - Alcohol can be an irritant to the small intestine and can also cause loose stools/diarrhea.

20 Fiber: Insoluble vs. Soluble Insoluble Fiber: -Does not mix with liquids and passes through the GI tract mostly intact. -May increase diarrhea, gas, bloating, and abdominal pain. -Coarse, scratchy fibers hurt an already inflamed intestine. OUCH! Insoluble fibers include the skin, seeds, and strings of fruits and vegetables. Sources: cellulose, bran, wheat products, whole grains, vegetables, fruits with edible seeds, lignin, hemicellulose

21 Cont Soluble Fiber: -Forms a gel when mixed with liquid and aids in bulking and moving food through the gut. May reduce diarrhea. -Smoother consistency moving through the bowel. - The inside flesh of fruits and vegetables often high in soluble fiber. Sources: gums, oats, legumes, guar, barley, pectin, apples, citrus, strawberries, carrots.

22 Hummus* Refried beans (smooth)* Pea soup* Instant oatmeal Peeled or canned pears Baked apples or applesauce Peeled plums * Gas forming (Bean-o may be helpful)

23 Fiber cont Recommendation: Include as much fiber as tolerated especially soluble fiber. Fiber will not make the disease worse, but can aggravate symptoms like gas, bloating, abdominal pain, and diarrhea. Fiber should be limited during a flare or if strictures present.

24 Foods to include for good health: Milk Group:* skim of nonfat milk, reduced fat cheeses i.e. 1% cottage cheese, part skim mozzarella, sherbet, low fat frozen yogurt, reduced fat yogurt, calcium fortified rice or soy milk. *(Lactaid may be helpful in those with Lactose intolerance) Meat Group: lean beef i.e. sirloin or tenderloin, poultry without skin, fish, (especially oily fish) water packed tuna, shellfish, eggs, tofu, ham, extra lean ground beef.

25 Foods Cont Vegetables: canned or well cooked: asparagus tips, beets, cauliflower*, broccoli*, winter squash i.e. butternut, zucchini, mushroom, carrots, pumpkin, white potato, sweet potato, tomato sauce, tomatoes without seeds or skin, vegetable juices. Caution with thick skinned or stringy vegetables and those that cause gas production*. Lettuce, spinach, and other greens may be tolerated in small amounts.

26 Foods Cont Fruits: Choose canned or cooked fruits without skins or seeds i.e. fruit juice without pulp, canned fruits like apricots, applesauce, mandarin oranges, peaches, pears, or raw bananas, soft seedless melon, papaya, mango, and peeled pears, plums, or peaches. Avoid raw apples, berries, dried fruit, oranges, kiwi, pineapple.

27 Foods Cont Grain Group: white bread i.e. enriched french or sour dough, potato, sweet potato without skin, instant oatmeal, seedless rye bread, white enriched pasta, white rice, instant brown rice, couscous, saltine crackers, rice crackers, water crackers, Cheerios, Rice Krispies, Rice Chex, Kix, Life, puffed rice, cream of wheat or rice, and fortified cereal i.e. Total. Caution with whole grains, bran, granola, whole wheat crackers, breads with nuts or seeds.

28 Is There a Special Diet for Patients With IBD? Several diets advertised specifically for managing IBD Many claims are supported y small numbers of subjects or patient testimony Most have not been proven scientifically and benefits have not been seen in formal studies. Talk to your doctor or dietitian about diet changes you are interested in trying.

30 Anti-inflammatory Diet Foods rich in antioxidants have been linked with decreased inflammation levels in the body. Research best associated with arterial inflammation. Inconclusive for IBD.

31 Cont Add antioxidant rich foods such as fruit juices, fruit in smoothies, pureed soups, pureed vegetables in casseroles i.e. lasagna or spaghetti sauce. Spices: i.e. turmeric, cumin, cinnamon, ginger Save vegetable cooking water and add to soups, drinks, sauces, casseroles. Include omega 3 rich foods such as salmon, tuna, omega 3 eggs.

32 Top Eight Food Allergens Tree Nuts Peanuts Fish Shellfish Eggs Soy Dairy Wheat Food Allergies

33 Food Allergies/Intolerances? Wheat Free Wheat contains protein (gluten) and sugars (fructans) Some IBD patients are sensitive to the fructans in wheat i.e. gas, bloating. Not harmful to intestinal cells but can be very uncomfortable. Wheat free diet may be helpful to reduce IBS type symptoms. Gluten Free Gluten is a protein found in wheat & other grains. Gluten intolerance/allergy increases antibody levels. Conditions: Celiac Disease & Dermatitis Herpetiformis. Not typically related to IBD. Damage to intestinal cells occur. Research has not shown GF diet effective for IBD.

34 What about FODMAPS Folks with IBD often have symptoms of IBS (Irritable Bowel Syndrome) FODMAPs (Fermentable Oligo, Di- and Monosaccharides and Polyols) can aggravate IBS symptoms. FODMAPS are: Fructose, Lactose, fructans, galactans, polyols i.e. sugar alcohols: sorbitol, mannitol, isomalt, xylitol.

35 FODMAPS Follow FODMAPs elimination diet for 1-2 weeks Assess symptoms: same, better, worse? Challenge each FODMAP group one at a time FODMAP tolerance often portion dependent Find your individual FODMAP threshold Important to work with a Registered Dietitian to ensure best results and help maintain nutritional status while eliminating foods from diet

36 Nutritional Supplementation: Oral liquid nutritional supplements: *Ensure, Enlive, Boost, Boost Breeze, Muscle Milk. *Carnation Instant Breakfast (If not lactose intolerant) *Orgain * Boost VHC (very high calorie) (amazon.com) * Scandishake *Homemade protein drinks and smoothies.

37 Enteral Nutrition Tube Feeding: *Formula administered through a feeding tube i.e. Osmolite, Jevity, Peptamen, Vital, Vivonex. Parenteral Nutrition or TPN: *Prolonged uncontrolled diarrhea *Ileus/bowel obstruction *Small bowel fistula *Short Bowel Syndrome

38 Other therapies: Probiotics: pills vs. fermented foods. Good bacteria that restore balance to the intestines Most studies have not show benefit except some UC Yogurt Kefir Kombucha Sauerkraut Tempeh Miso

39 Other therapies: Omega 3 fatty acids fish oil supplements Large well controlled trials showed no benefit in CD Food sources: fatty fish, omega 3 eggs, flax seed, flax seed oils, walnuts, nut butters

40 Amino acid supplementation Glutamine No benefit found to reduce IBD Some benefit for post operative healing. Arginine No benefit found to reduce IBD Large body of evidence for pre-operative use to support infection reduction and healing after colorectal surgery

41 Optimizing Nutrition in IBD: Summary Eat healthy, nutrient rich foods that are easily digested. Include foods high in protein. Consume adequate calories to maintain weight. Include fiber as tolerated, especially soluble fiber. Choose antioxidant rich foods.

42 Cont. Include calcium rich foods. Drink 8 to 12 cups of fluid to maintain hydration. Take supplements to replace lost nutrients. Work with MD and RD to design comprehensive treatment plan.
