Myths and Misperceptions- Pet Food Ingredients

  1. 1. Alexia Heldman DVM June 2, 2016 MYTHS AND MISPERCEPTIONS PET FOOD INGREDIENTS
  2. 2.  1. Pet owners are concerned about the ingredients.  2. Ingredients should be selected for their nutrient content 3. Finished product also depends on processing and cooking KEY POINTS
  3. 3.  Lots of folks think, “Oh my gosh there’s chemicals in my food! I’m here to tell you that food is made of chemicals, that’s the way it’s made here on planet earth. Everything is a chemical”- Dr. Nathan Myhrvold  Why are chemicals included?  Are actually essential vitamins and minerals  Meat byproducts are scary  Organs and other nutritious parts  Too many believe what they read on the internet despite peer reviewed published data PET OWNERS DO NOT WANT CHEMICALS
  4. 4.  AAFCO- Voluntary charged by law to regulate the sale and distribution of animal feed  Nutritional claims, acceptable ingredients  Animal digest- highly palatable protein  BHA- Butylated Hydroxyanisole Antioxidant  Brewer rice- broken grains  Meat byproducts- protein source of organ meats, scrap meat, bone, blood, and fatty tissue----which do not include hair, hide, horns, hooves, teeth, or intestinal content!  Menadione Sodium- Vitamin K  Tocopherols- Natural source Vitamin E  TBHQ- Tertiary butyl hydroquinone  Whole Grain- bran, germ, and endosperm COMMONLY USED INGREDIENT TERMS
  5. 5.  Why?  1. Often called a “filler”  2. Quality of grains are questioned  3. Grain can manifest as allergies GRAIN FREE PET FOOD
  6. 6.  Good carbohydrate source  75% starch  6-10% protein  4% fat  7% fiber  Legal definition of filler is little to no nutritional value WHOLE CORN
  7. 7.  Abnormal reaction to a normal food or ingredient  Signs:  GI or dermatologic or both  Vast majority are to the proteins or glycoproteins ALLERGIES AND GRAINS
  8. 8. MOST COMMON FOOD ALLERGENS FOR DOGS AND CATS Beef- 36% Beef- 20% Dairy-28% Dairy -14.6% Wheat- 15% Fish- 13% Egg-10% Lamb- 6.7% Chicken 9.6% Poultry- 4.5% Lamb 6.6% Barley/Wheat- 4.5% Soy 6% Dog Cat Verlinden A, Hesta M, Millet S, et al. Food allergy in dogs and cats: a review.
  9. 9.  Needed in a form of glucose for the brain, nervous tissues, and RBC.  If not provided you have de novo gluconeogenesis from amino acids and glycerol backbone of triglycerides. ARE CARBOHYDRATES A DIETARY REQUIREMENT FOR CATS AND DOGS?
  10. 10.  Not necessarily low in dietary carbohydrates  Other sources of carbohydrates  Potatoes  Beans  Tapioca  Peas GRAIN FREE DIETS
  11. 11.  Can they digest carbohydrates?  Both cats and dogs lack salivary amylase  Both have pancreatic amylase, and have intestinal disaccharides  Dietary carbohydrates/simple sugars, starches, fiber  Proper processing is crucial  Poorly digestible carbohydrates or an overload of simple sugars may induce adverse changes in intestinal metabolism. True for cats given 25-40% sugar or starches CATS ARE CARNIVORES
  12. 12.  Pet owners are concerned about the meaning, content, and source  Lack of understanding may confuse pet owners, and they perceive that these are poor quality ingredients  Consists of edible parts and organs such as; heart, lungs, liver, meat trimmings, and bone  Do not include hair, hide, horns, hooves, teeth, or intestinal content  May actually provide more nutritional benefits  Many are considered a delicacy in other cultures MEAT AND POULTRY BY PRODUCTS
  13. 13.  May greatly influence the quality of protein produced  Can affect protein digestibility of finished pet food  Pet food companies contract with specific supplier for consistent quality  Those affiliated with USDA inspected plants receive animal products only from those facilities Urban legend is that pet foods contain rendered remains of pets RENDERING
  14. 14.  Rendering is recycling  A secret no more  Good for animal health  Rendering is sustainable  Clean and safe  Consumers can have confidence  Volume in/quality out 56B # raw10B # fats and 9B#protein RENDERING FACTS
  15. 15.  Quality is determined  By amino acid composition  Digestibility  Ability to meet amino acid requirements  Example- Soy protein provides 100% of essential amino acids, but is deficient in methionine and scores lower.  By mixing proteins in a diet, the finished product can provide excellent protein quality, even though individual components have limitations ANIMAL VS VEGETABLE PROTEIN
  16. 16.  Raw food diets suggests that cooking decreases nutritional value and destroying inherent enzymes.  Natural enzymes add little, if any, value to digestibility  Are not specialized and do not help digestion  Grains benefit from cooking  Cooking increases digestibility between 14-208% Carmody RN, Wrangham RW. The energetic significance of cooking. EFFECT COOKING HAS ON QUALITY AND DIGESTIBILITY
  17. 17.  Effect on nutrient quality and digestibility can vary with type of cooking method, temperature, time, and moisture.  Extrusion uses a combination of:  Moisture (25-35%)  Temperature between 100 and 150C  Pressure 20-30 bars  Mechanical sheer (0.5- 5 minutes)  Correct extrusion favors higher retention of amino acids, protein and starch digestibility, decreased lipid oxidation, higher retention of vitamins.  Extrusion denatures undesirable enzymes such as: trypsin inhibitors and phytates. Sterilizes the finished product EXTRUSION COOKING
  18. 18.  Pyridoxine hydrochloride- Vitamin B6  Menadione sodium bisulfite- Vitamin K  Copper Proteinate- Dietary copper  40+ essential nutrients that dogs and cats need  Tocopherols or vitamin E- natural antioxidant  BHA, TBHQ or ethoxyquin- synthetic antioxidant  Without antioxidants essential fatty acids become oxidized or rancid and nutritional value is destroyed PET OWNERS MAY NOT RECOGNIZE
  19. 19.  Pet parents want transparency and trust  Pet specialty rules:  3278 new pet food products introduced in to the US in 2015, Maria Lange Business Group Director for GFK  Sustainability is a main concept  Pet food purchasing patterns are related to the type and amount of protein content TRANSPARENCY
  20. 20.  Paleo, GMO free, grain free, natural, freeze dried  US sales- $5.5 billion, representing 10% growth BUZZWORDS BACKED BY NUMBERS
  21. 21.  Pets require specific nutrients not specific ingredients  Pet food manufacturers formulate diets to be complete and balanced  Ingredients should be selected for nutrient content, as well as impact for palatability, digestibility, and consumer preferences.  Finished product also depends on processing and cooking SUMMARY
