3. The onset of CD can occur at any age.
All people diagnosed with CD will have intestinal damage.
The villi become inflamed, flattened and disappear.
Nutrients, including carbohydrates, proteins, fats, vitamins and minerals, can no longer be absorbed.
This leads to malnutrition and other serious health problems.
4. Genetic Properties
Celiac Disease is a true autoimmune disease
The genetic predisposition (HLA), the exogenous trigger (Gluten) and the autoantigen (tTG) are all known
CD is currently the only autoimmune disease for which all three factors are known
Unlike many other autoimmune diseases, the cause of the disease has been identified
5. Frequency of Occurrence CD occurs in almost 1% of the population.
CD occurs in 1 in 22 first degree relatives. Canadian Research 12-15 per cent
CD occurs in 1 in 39 second degree relatives. Canadian Research 5-12 percent
CD occurs in 1 in 56 people with gastro-intestinal symptoms.
CD occurs in 1 in 133 of the ‘not at risk population.
6. Diagnosing Celiac Disease
A series of serologic tests can assist in the preliminary screening for CD
An intestinal biopsy must be performed to confirm the diagnosis of CD
The Gluten-Free Diet should never be started without an accurate diagnosis of Celiac Disease
7. The only treatment for Celiac Disease is a
STRICT GLUTEN-FREE DIET FOR LIFE
Even small amounts of gluten can be harmful to people with Celiac Disease and can cause continued small bowel damage. Treatment of CD
8. What Happens When We’re Glutened? The accidental ingestion of gluten does not cause the profound anaphylactic response that is common with peanuts and other allergens.
9. Many people with CD will have immediate intestinal symptoms.
Many will have headaches or other non- intestinal symptoms.
Many will have delayed symptoms.
Many will have no symptoms but will still have intestinal damage which can lead to other illnesses. What Happens When We’re Glutened?

13. Major Concerns
Increase Awareness
Safe Ingredients
Hidden Sources of Gluten
CROSS CONTAMINATION
14. What is Gluten ?
Gluten refers to several different cereal grain storage proteins, or prolamins.
Gliadin in wheat
Secalin in rye
Hordein in barley
15. Gluten Containing Grains & Grain Products Barley Bulgar Cereal Binding
Couscous Durum Einkorn
Emmer Filler Farro
Graham flour Kamut Malt
Oats* Roux Rye
Semolina Spelt(Dinkel) Triticale
Wheat
Oats are currently excluded from the gluten-free diet because of the high risk of contamination from gluten containing grains
16. Gluten-Free Grains & Grain Substitutes Amaranth Arrowroot Buckwheat
Cassava Corn (Maize) Dahl
Flax Legumes Millet

19. Preventing Contamination &Cross-contamination When preparing a gluten-free meal, it is important to prevent contamination of the gluten-free foods with gluten-containing food particles and residues.
Even small amounts of gluten can result in continued intestinal damage for people with CD and DH
Care must be taken to ensure that gluten-free foods remain gluten-free.
20. Preventing Contamination &Cross-contamination Select a preparation area that is separate from other food preparation areas.
Air-borne flour and other gluten-containing particles can contaminate gluten-free foods.
Ensure all preparation surfaces, cooking surfaces and cooking utensils have been thoroughly cleaned, including counter top, meat slicer, grill surface, cutting boards, bowls, knives, utensils, thermometers, cleaning cloths.
21. Use dedicated pots, pans, utensils and cutting boards whenever possible.
Rolled edge pans are easier to clean.
Scrub with soap and water to ensure removal of gluten-containing particle. Disinfect according to current standards of practice. Preventing Contamination &Cross-contamination
22.
Follow impeccable hand washing practices.
Use sanitary gloves for food preparation and change them before handling GF foods.
Ensure the powder used is gluten-free. Even powder-free gloves can have trace amounts of powder.
Become knowledgeable about special needs diets and menu selections.
Educational programs are offered through many of the local chapters of the Canadian Celiac Association. Preventing Contamination &Cross-contamination
23. Ensure all ingredients are gluten-free.
Check product ingredients regularly. Manufacturers and suppliers can change ingredients without notice.
Ensure that anti-caking and flow agents are GF. These agents may not be identified in the ingredient lists.
Use boldly labeled, air tight containers for all products designated as GF.
Prepare GF meals before other menu selections Preventing Contamination &Cross-contamination
24. Preventing Contamination &Cross-contamination Clean utensils must be used for each condiment, butter, sauce and all other items.
Use individual portions and/or squeeze bottles.
Deep fryer oil previously used for gluten-containing foods is unsafe for gluten-free cooking.
Fresh water must always be used for boiling, poaching or steaming.
25. Preventing Contamination & Cross-contamination Use the top oven racks.
Use caution with convection ovens.
Use toaster bags to prevent contamination of GF bread products.
Arrange buffet tables with gluten-free selections first and separated from the gluten-containing selections. Label them.
Bulk bins can be a source for cross-contamination.
26. Using Safe Alternatives Many common food products have safe alternatives: Eg. Soy sauce.
Safe thickening agents can be used in place of flour: Eg. Potato starch, tapioca starch.
Select pure spice blends rather than seasoning blends that may contain gluten-containing fillers.
27. Using Safe Alternatives
Many foods start out gluten-free and are glutened in menu preparation: Eg. Salads
Many food items have gluten-free alternatives: Eg. Pizza shells, pasta
Develop clearly identified gluten-free alternatives as part of a standard menu.
28. Baking Gluten-Free
Gluten-free baking can be very challenging
Gluten is the ingredient that allows bread to rise and stay moist and fluffy
Gluten-free products can be dry and dense
Where do you start to make it great???
29. Baking Gluten-Free
Use a combination of gluten-free flours
Course flours require more leavening than wheat flour – 2 ˝ tsp B Powder per cup
Using buttermilk in place of regular milk gives a lighter texture
Add more egg or oil to increase moisture
Gelatin also increases moisture
30. Baking Gluten-Free Xanthan gum can be used as a stabilizer and binder – 1 tsp per cup
Guar gum is also a stabilizer and is less expensive
Guar gum is best used in baking that doesn’t require yeast
Bake in small portions at a lower temperature for a longer time
Use dull or dark pans to absorb heat for better browning
31. Baking Gluten-Free
Adding chips, nuts and dried fruits improves the flavour
Let non-yeast doughs rest for 30 minutes before baking
Cornstarch and tapioca can be used to thicken sauces and fruit pies
Let pancake batter rest for 15 minutes before cooking. Do not stir before use
32. Baking Gluten-Free
Brown rice cereal or flaked rice can be substituted for oatmeal
Instant potato flakes and crushed rice cakes can be substituted for bread crumbs
Store baked products in plastic bags while still warm
Freeze baked products to minimize loss of moisture and flavour
33. Bread and Buns
Use fresh ingredients
Be exact in your measurements
Use ingredients at room temperature
Different brands and grinds of rice flour may require a variation in the amount of liquid
Whipping the eggs or egg substitutes gives a better texture
34. Bread and Buns Unflavoured gelatin adds spring to the texture of the bread
A teaspoon of vinegar or dough enhancer helps the yeast to work
Changes in weather and season can affect bread making. It may be necessary to adjust ingredients
Gluten-free dough has the consistency of thick cake batter
Gluten-free bread doesn’t require kneading
35. Bread and Buns It is not necessary to let gluten-free bread rise twice as there is no gluten to develop
Gluten-free dough likes to be cuddled – use small loaf pans
Place a pan of water in the oven during baking
Allow the bread to cool before slicing.
Separate slices with wax paper before freezing
36. Cookies
Use glutenous flour for ˝ the flour requirement in a recipe
Use crumbled sliced almonds, flaked GF cereal or textured soy protein to replace oatmeal
For delicate butter cookies, choose a flour mix with more starch (tapioca or potato) and sweet rice
37. Cookies
Xanthan and/or guar gum are seldom needed in cookie dough
Add an extra egg to prevent crumbling
Rice bran and rice polish add flavour, fiber and nutrition
38. Pastry GF pastry does not toughen when rolled repeatedly
When mixed, pastry should be very moist
Wrap in plastic and chill several hours, until cold and firm
Use white rice flour to flour the surface for pastry rolling
When used for quiche, bake the unfilled shell 5 minutes before filling
