  11. 11. What is a Healthy Diet? Atkins Diet? Vegetarian/Vegan? Zone Diet? Macrobiotic? South Beach Diet? Juicing? Food Combining? Metabolic Typing? All Raw?
  12. 12. Or is it the US Government Official Diet. . . . . . designed to promote the products of commodity agriculture?
  13. 14. Traditional Diets?
  14. 15. Primitive Aborigine Women
  15. 16. Primitive South Pacific Boys
  16. 17. Great Variety in Traditional Diets Some had no plant foods Some had few animal foods Some had mostly cooked foods Some had large amounts of raw foods Some had milk products; some did not Some had grains; some did not Some had fruits; some did not What are the underlying characteristics of these healthy diets?
  17. 18. 1. No refined or denatured foods Refined and Denatured Food Components 1930's Refined Sugar White Flour Vegetable Oils Canned Foods Condensed Milk Refined and Denatured Food Components Today Refined Sugar High Fructose Corn Syrup White Flour Pasteurized Milk Skim and Low Fat Milk Hydrogenated Fats Refined Vegetable Oils Isolated Protein Powders Additives
  18. 19. FISH AND SHELLFISH : including organs, oil, bones, heads, etc. Weston Price found the best bone structure among those eating seafood BIRDS : Chicken, ducks, geese, etc., including the organs, fat and skin. RED MEAT : Beef, goat, sheep, game, etc., with ORGAN MEATS and FAT preferred. MILK AND MILK PRODUCTS EGGS REPTILES INSECTS 2. Most diets contained animal products
  19. 20. THESE NUTRIENTS ARE MOSTLY or ONLY IN ANIMAL PRODUCTS Vitamin A Vitamin D Cholesterol Vitamin B12 Very Long Chain, Superunsaturated fatty acids (AA, EPA and DHA) Key Animal Food Nutrients THESE NUTRIENTS ARE MORE EASILY ABSORBED FROM ANIMAL PRODUCTS Calcium B6 Magnesium Iron Zinc Copper
  20. 21. 3. Calcium, Minerals and Fat-Soluble Vitamins “ Primitive” Diets contain 4 times the calcium and other minerals , and 10 times the fat-soluble vitamins as the modern American diet.
  21. 22. Bricks and Mortar The body is like a house or temple, built of bricks and mortar Bricks = Minerals Mortar = Fat-Soluble Activators A and D
  22. 23. Some Sources of Vitamins A and D SEAFOODS Fish Eggs Fish Livers Fish Liver Oil Fish Heads Shell Fish Oily Fish Sea Mammals LAND ANIMALS GRASS-FED! Insects Butter and Cream Egg Yolks Liver, Organ Meats Animal Fat (Especially mono-gastric animals such as (birds, pig, bear, Guinea pig)
  23. 24. Food Sources of Vitamin K TESTED SOURCES Natto (fermented soy) Goose Liver Cheeses Egg Yolk Butter Chicken Liver Fatty Meats Sauerkraut OTHER PROBABLE SOURCES Goose, Duck and Chicken Fat Crustacean “Butter” (Hepatopancreas) Bone Marrow Other Organ Meats Fish Eggs Fermented Cod Liver Oil
  24. 25. Calcium PRIMITIVE DIETS: At least 1500 mg per day US GOV’T RECOMMENDATION: 800-1200 mg per day 1500 Mg Calcium is in: 5 Cups Whole Milk = 805 calories 7-8 Ounces Cheese = 900 calories 40 Carrots = 1680 calories 9 Cups Ice Cream = 2517 calories 32 Chocolate Cupcakes = 4117 calories 4.5 Cups Almonds = 4077 calories 78 Slices Whole Wheat Bread = 4305 calories
  25. 26. 4. All cultures cooked some or most of their food… but they always ate some of their foods raw .
  26. 27. 5. High Levels of Enzymes and Beneficial Bacteria
  27. 28. Types of Enzymes METABOLIC (1,000s discovered) Delta desaturase Superoxide dismutase Gluththione peroxidase Catalase Lysyl oxidase DIGESTIVE (about 22) Pancreatin Pepsin Trypsin Lactase Galactase Phosphatase FOOD (3 types) Amalyses Lipases Proteases When the diet contains food enzymes, the body is spared from making some digestive enzymes and therefore has more energy. Food enzymes are destroyed at 118 o F wet heat, 150 o F dry heat.
  28. 29. Examples of Enzyme-Rich Foods Raw dairy products Raw meat and fish Raw honey Tropical fruits Cold pressed oils (extra virgin olive oil) Wine and unpasteurized beer Lacto-fermented (enzyme enhanced) vegetables fruits meats fish dairy products beverages
  29. 30. Beneficial Bacteria OLD PARADIGM: Healthy human body is sterile and microbes attack it, making us sick. NEW PARADIGM: Healthy human body lives in symbiotic relationship with microorganisms. SIX POUNDS of healthy bacteria in our digestive tract Digest our food Assist in assimilation Create nutrients Protect us against toxins Help us feel good Without good bacteria, we are dead!
  30. 31. Lacto-Fermented Condiments provide enzymes and good bacteria Beet relish Ginger carrots Cortido (spicy So. American sauerkraut) Pineapple chutney Raspberry syrup Apricot butter
  31. 32. Lacto-Fermented Beverages Kombucha Kvass Sour Grain Drink
  32. 33. 6. Seeds, grains, legumes & nuts are soaked, sprouted, fermented or naturally leavened Deactivates ENZYME INHIBITORS (block digestion) Neutralizes PHYTIC ACID (blocks mineral absorption) Neutralizes TANNINS and LECTINS (irritants) Pre-digests COMPLEX STARCHES & SUGARS (hard to digest) Begins breakdown of GLUTEN (hard to digest; can be toxic) Begins breakdown of CELLULOSE (impossible to digest) Proper preparation makes seed foods more digestible and their nutrients more available.
  33. 34. Proper Preparation of Seed Foods Imitates natural factors that neutralize the seed’s “preservatives” and allow it to sprout: Moisture Warmth Slight Acidity Time
  34. 35. 7. Total fat content of traditional diets varies from 30% to 80% of calories, but only about 4% of calories come from polyunsaturated fatty acids.
  35. 36. Longer-Chain Fatty Acids
  36. 37. 18-Carbon Fatty Acids
  37. 38. Arteries: The Good and the Pathological Good artery - smooth, elastic and pink. Saturated and mono-unsaturated fats do not react or harm arteries. Damaged arteries - crusty and yellowish. Damage caused by free radicals from rancid, processed vegetable oils!
  38. 39. Shorter-Chain Fatty Acids
  39. 40. Triglyceride
  40. 41. Who’s Afraid of Saturated Fat? Clogs arteries! Causes Cancer! Inflammation! Makes you fat! Bad for the liver! Heart attack!
  41. 42. The Many Roles of Saturated Fat CELL MEMBRANES – should be 50% saturated fatty acids. BONES – Saturated fats help the body put calcium in the bones. HEART DISEASE – Lower Lp(a), a marker for heart disease. HEART FUNCTION – Saturated fats are preferred food for the heart. LIVER – Saturated fats protect the liver from alcohol & other poisons. LUNGS – Can’t function without saturated fats. KIDNEYS – Can’t function without saturated fats. IMMUNE SYSTEM – Enhanced by saturated fats. ESSENTIAL FATTY ACIDS – Work together with saturated fats. DETOXIFICATION – Supports body’s detox mechanisms
  42. 43. The Many Roles of Short and Medium-Chain Fatty Acids METABOLISM – Raise body temperature and give quick energy WEIGHT LOSS – Never stored as fat; used for energy IMMUNE SYSTEM – Stimulate the immune system INTERCELLULAR COMMUNICATION – Help prevent cancer ANTI-MICROBIAL – Kill pathogens including candida in the gut
  43. 44. Modern Edible Oil Processing Source: Fats and Oils: Formulating and Processing for Applications , Richard D. O’Brien 1998
  44. 45. Problems Associated with Consumption of Polyunsaturated Oils Increased cancer Increased heart disease Increased wrinkles and premature aging Immune system dysfunction Disruption of prostaglandin production Depressed learning ability Liver damage Ceroid storage disease Damage to reproductive organs and the lungs Digestive disorders due to polymerization Increased levels of uric acid Impaired growth Lowered cholesterol Source: Pinckney, The Cholesterol Controversy
