Learning Objectives Describe three symptoms of celiac disease State two conditions associated with untreated celiac disease Identify three grain alternatives that are gluten free

What Is Celiac Disease (CD) Autoimmune digestive disease Damages villi of small intestine Interferes with absorption of nutrients from food Those with CD cannot tolerate gluten Also called Gluten-sensitive enteropathy Sprue Non-tropical sprue Celiac sprue It is NOT an allergy

Cause of Celiac Disease Still unknown

What is Gluten? General name for prolamins (storage proteins) in wheat, rye, barley Toxic prolamins Gliadin in wheat Secalin in rye Hordein in barley

Some CD Statistics 1 in 133 or 1% of American population has Celiac Disease or CD (about 3 million people)¹ 1 in 141 or 0.71% of Americans have CD² In 70% of identical twin pairs, both twins have the disease³ Family members who have an autoimmune disease are at a 25% increased risk of having celiac disease³ ¹Prevalence of Celiac Disease in At-risk and Not-at-risk Groups in the United States. Arch Int. Med. (2003) 163:286 ²The American Journal of Gastroenterology 107, 1538-1544 (October 2012) ³Nationl Foundation For Celiac Awareness, Updated Feb. 28, 2013

Statistics (cont’d) Estimated 85% of Americans who have celiac disease are undiagnosed or misdiagnosed with other conditions¹ 6-10 years is the average time a person waits to be correctly diagnosed² 5-22% of celiac patients have an immediate family member (1st degree relative) who also has celiac disease¹ Burden of disease over four-year period per patient:  Celiac-free males: $4,019 Males with CD:  $14,191¹ May is Celiac Awareness Month ¹National Foundation for Celiac Awareness, Updated Feb. 28, 2013 ²Source: Daniel Leffler, MD, MS, The Celiac Center at Beth Israel Deaconness Medical Center

Symptoms Celiac Disease Lactose intolerance Bone pain Easy skin bruising Edema of hands and feet Joint pain Delayed growth Weight loss or gain Osteoporosis Headaches Depression/irritability Hair loss Abdominal pain Bloating/gas Diarrhea and/or constipation Indigestion/reflux (“heartburn”) Nausea and vomiting Fatigue/lethargy Muscle weakness Itchy skin rash Tingling/numbness Mouth sores

Symptoms of CD (cont’d) Iron, folate and/or vitamin B12 deficiency Other vitamin and mineral deficiencies (A,D, E, K, calcium) Elevated liver enzymes Discolored teeth Migraine headaches Depression Menstrual irregularities Infertility in both women and men Recurrent miscarriages

Celiac Disease Risk Factors An immediate family member with CD Presence of HLA-DQ2 and HLA-DQ8 genes About 95% of people with celiac disease have the HLA-DQ2 gene Most of the remaining 5% have the HLA-DQ8 gene Major life event, emotional stress, pregnancy, or surgery in those who are genetically predisposed Those with other autoimmune disease Those with another genetic disorder Infants—exposure to gluten before 3 months of age

Some Disorders/Conditions Associated More Frequently with CD Type I diabetes Thyroid disease Liver disease Sjögren’s syndrome Lupus Addison’s disease Scleroderma Alopecia areata Rheumatoid arthritis Turner syndrome Raynaud’s syndrome

Diagnosis of CD Symptoms Blood test Small bowel biopsy Should be tested while on a gluten-containing diet

Serologic Tests No standardization in testing for diagnosis of CD Anti-tissue transglutaminase antibodies (tTGA) Anti-endomysium antibodies (EMA) Gluten free diet should not be started before blood tests and biopsy

Diagnosis—The Biopsy Diagnosis: Intestinal Biopsy A biopsy of the small intestine can confirm the findings of the blood test. Celiac disease damages or destroys the villi in the intestine

What Does Celiac Disease Look Like?

Refractory Celiac Disease Very small percentage of people with celiac disease do not respond to a gluten-free diet. May be prescribed glucocorticoids or at times immunosuppressants are indicated to induce remission

Dermatitis Herpetiformis (DH) Another form of celiac disease Chronic skin condition Intense burning Itchy and blistering rash Often misdiagnosed as eczema, contact dermatitis, allergies, hives, herpes, or psoriasis Many with DH have varying degrees of small intestinal villous atrophy Diagnosis—skin biopsy from unaffected skin adjacent to blisters or erosions Treatment is a strict gluten free diet for life

Some Complications of Untreated CD MalabsorptionMalnutrition Low blood glucose or swings in blood glucose Osteoporosis Infertility Neurological problems Lactose intolerance Cancer

Treatment for CD Only known treatment is strict gluten free diet for life! Additional vitamin and mineral supplements may be needed to correct malnutrition Some may also need to eliminate lactose until damaged bowel is healed

Contain Gluten (from wheat) Atta Bulgur Couscous Durum Einkorn Emmer Farina Graham flour Hydrolyzed wheat protein Kamut Motzoh, Matzoh meal Modified wheat starch Seitan Semolina Spelt (a form of wheat) Dinkel Farro or Faro Triticale Wheat Wheat bran Wheat flour Wheat germ Wheat starch

Contain Gluten (from barley) Ale Barley (flakes, flour, pearl) Beer Brewer’s yeast Lager Malt Malt extract, malt syrup, malt flavoring Malt vinegar Malted milk

Contain Gluten (from rye) Rye bread Rye flour

Commonly Have Gluten Red Flags For Gluten “Hidden” Gluten Processed meat Potato chips French fries Breaded foods Malt (made from barley) Hydrolyzed Vegetable Protein (often contains wheat) Sauces Soy sauce (made from soy & wheat) Marinades Gravy Salad dressings Candy Flavored coffees and teas Nutritional supplements Soups In bread, cereal, pasta, crackers, baked goods Wheat Rye Barley

Controversial Oats Oatmeal Oat bran Oat flour Oats Safety of oats much debated Barley often contaminates oats Wheat contaminates oats Only consume pure, uncontaminated oats Best to be labeled or certified as “gluten free”

Gluten Free Grains/Flours/Starches Rice Corn (maize) Soy flour Potato flour Tapioca Bean flour Garfava flour Sorguhm Quinoa Potato flour/starch Millet Buckwheat Arrowroot flour Amaranth Teff Montina® (Indian ice grass) Flax Nut flours Cornmeal Cornstarch

Using Gluten Free Flours Buy items made with whole grain flour and bean flour to get healthier nutrients GF often lower in fiber Purchase products with added vitamins and minerals Refined carbohydrates often in GF products generally make baked goods higher in calories and total carbohydrate than regular versions Replacing regular bread, muffins, baked goods for GF products without regards to calories weight gain

MAY Contain Gluten •Brown rice syrup •Breading & coating mixes •Croutons •Energy Bars •Flour or cereal products •Imitation bacon •Imitation seafood •Marinades •Panko (Japanese bread crumbs) •Pastas •Processed luncheon meats •Sauces, gravies •Self-basting poultry •Soy sauce or soy sauce solids

MAY Contain Gluten •Soup bases •Stuffings, dressing •Thickeners (Roux) •Communion wafers •Herbal supplements •Prescription drugs & over-the-counter medications Lipstick •Nutritional supplements •Vitamins & mineral supplements •Play dough: a potential problem if hands are put on or in the mouth while playing with play dough Hands should be washed immediately after use

Wine, Distilled Alcohol Beer and Ale Wine, Distilled Alcohol Has gluten from barley malt ONLY have gluten free beers or ale that are so labeled And IF your healthcare provider allows Wine and distilled alcohol are generally safe As long as your healthcare provider allows alcohol

Let Food Be Thy Medicine Incorporate whole foods into gluten free diet Reverse nutritional deficiencies Restore gut health

Nutrient-Dense Gluten Free Diet Adhere to a total (100%) gluten free diet Need nutrient-dense foods to regain health Need proper nutrition to restore gut health Focus on whole foods vs. highly processed gluten free packaged foods (& prepare without ingredients that contain gluten) Meat Fish Eggs Rice Beans Fruits Vegetables

Cross-Contamination Concerns Preparing foods on common surfaces with gluten items Using utensils that are not thoroughly cleaned after preparing gluten-containing foods Using a common toaster for GF bread and regular bread is a major source of contamination Sharing flour sifters with gluten-containing flours Deep frying foods cooked in oil shared with breaded products containing gluten Using knives for spreadable condiments for both gluten free and gluten-containing products

Label Reading A must for those with celiac disease Carefully check the ingredient list

Food Allergen Labeling and Consumer Protection Act of 2004 (FALCPA) (Public Law 108-282, Title II) of the FDA Food labels to clearly identify wheat and other common food allergens in list of ingredients Eight major foods or food groups— Milk Eggs Fish (e.g., bass, cod, flounder) Crustacean shellfish (e.g., crab, lobster, shrimp) Tree nuts (e.g., almonds, walnuts, pecans) Peanuts Wheat Soybeans Develop and finalize rules for term “gluten free” on product labels (not done yet)

“Gluten Free” FDA gluten free labeling to be voluntary FDA proposing to define the food labeling term "gluten-free" to mean a food bearing this claim does not contain any of the following: An ingredient that is a "prohibited grain," which refers to any species of wheat (e.g., durum wheat, spelt wheat, or kamut), rye, barley, or their crossbred hybrids An ingredient (e.g., wheat flour) that is derived from a "prohibited grain" and that has not been processed to remove gluten An ingredient (e.g., wheat starch) that is derived from a "prohibited grain" that has been processed to remove gluten, if the use of that ingredient results in the presence of 20 micrograms or more gluten per gram of food (i.e., 20 ppm) Or 20 micrograms or more gluten per gram of food

Some Gluten Free Symbols

Eating Gluten Free Grocery Shopping Eating Out MANY gluten free foods available now Various stores carry gluten free foods Must ask, ask, ask Some restaurants do have gluten free menu items

Reverse Nutritional Deficiencies Iron Calcium Vitamin D Zinc Magnesium Vitamin K Folate Vitamin B6 Vitamin B12 Fiber

Reverse Nutrition Deficiencies (cont’d) Foods first Supplements as necessary Nutrients often cannot be absorbed until intestinal site of absorption heals Improvement in nutrient stores important Indicates intestines are healing Indicates adherence to gluten free diet Follow up blood to test antibodies and nutrient levels is important

Reverse Nutrition Deficiencies (cont’d) Ensure medications and supplements are gluten free Be aware of physiological reasons someone may not be absorbing certain nutrients Then make recommendations and monitor Provide tips for maximizing nutrient uptake

Restore Gut Health Number one way to improve gut health is removing gluten from diet May take longer to restore gut health for some Some may need steps beyond gluten free diet Digestive health and integrity of gut lining play important roles in immune health

Remember Wheat free is not gluten free When in doubt, go without May be contamination in food preparation Stay symptom free with gluten free Eating gluten free is work

Who Is Buying Gluten Free Those who suffer from celiac disease Those who are sensitive to gluten Those who think gluten free products are healthier Those who follow a trend in the news

Future Possibilities Gluten-degrading enzymes Modified grains that lack immunogenic compounds Zonulin inhibitors that decrease intestinal permeability Anti-inflammatory therapy Immunotherapy Hookworms

Tax Deductions The cost of gluten-free (GF) food that is in EXCESS of the cost of the gluten containing food that you are replacing The full cost of special items needed for a GF diet may be deducted If you make a special trip to a store to purchase GF foods, the actual cost of your transportation to and from the store is deductible The full cost of postage or other delivery expenses for GF foods made by mail order are deductible
