Description
Health food Business: Hippocrates  “let thy food be thy medicine” - visionary False: No empirical evidence - lettuce cools the body and curbs the passion - pigeon droppings are great for baldness - physician without a knowledge of astrology has no right to call himself a physician - flax is great for the intestines Food and the Prevention of Disease Sylvester graham (1794-1851) - little progress about quality of food  people too concerned about getting any food - son of a preacher o food for the body, not just the soul o “Dr. No”  no meat, spice, caffeine, alcohol (stimulants) o no doctors –doctors back then were not good o no self-abuse - should eat graham crackers  made of whole wheat flour o made to combat inflammatory factors in meat o high in fibre low in fat - “you are what you eat” o using food as prevention, not just medicine o food is the only raw material that goes into our body  they make up our molecules Health food stores: - rarely see any food  mostly supplements, juices o all hype Health food terms: Natural = no additives (no scientific definition) - “natural” does not mean “safe” - synthetic does not mean dangerous - ex. Hemlock plant contains coniine Organic - regulations: o no additives o no “chemical fertilizers” o no synthetic pesticides o no genetically modified components - why buy organic 1) for what it does not contain (no pesticide residues)  although most foods contain pesticides, danger depends on dosage of residue  presence of pesticides does not equal risk  pesticide levels in food are regulated  random samples  ex. EWG claims that Apples can have up to 36 pesticides  no farmer in the world would use all 36 acceptable pesticides  80% of fresh foods that are tested are residue free, 90% of processed foods are pesticide free  organic foods also contain pesticides  ex. Copper sulfate –natural substance  no safer than synthetic pesticides o both natural and synthetic pesticides have to pass the same regulations  parkinson’s has been linked to natural pesticide (derived from plant that contains rotenone) o Bacillus thuringiensis  insecticidal proteins  Insecticidal protein gene cannot be inserted into organic agriculture due to regulations o Organic foods are likely to contain e coli.  uses animal manure as fertilizer 2) for what it does contain (more nutrients) Nutritional quality depends on - variety type - soil quality - fertilizers - crop rotations - maturity at harvest - transportation no scientific studies show that organic foods are more nutritious o scientific data can be twisted to make it seem like it is more nutritious  organic soups have 6 times more salicylic acid (0.006mg vs 0.01mg)  absolute difference is insignificant  salicylic acid is good for the body  anti-coagulant (81mg in aspirin) o organic food has significantly higher contamination o benefits from eating organic only likely during embryonic stage and early feeding  nervous system, brain and organs are being formed  small interventions can have large effects 3) environmental concerns a. most supportable reason scientifically (no fertilizer run off ex.) Is “organic” organic? - Industry is full of fraud –hard to check - Canada o Mainly based on honor code o Must not have grown any conventional crops for 3 years o Follow national organic guidelines  No one checks! Only some random inspections Marketing Organic Ex 1. Natural lemon flavored crème pie - ingredients: sodium propionate, sodium benzoate, certified color, vegetable gum natural usually means additive free –how are they getting away with it? - they are using “natural” lemon flavoring Ex 2. Trader joe’s “all natural jelly beans” - no artifical flavouring Ex 3. – Organic chickens “hormone free” and “soybean fed” - chickens have hormones –its natural - what they imply is that there are no hormone additives - there are no hormones used in chickens-its illegal - chickens are meant to eat soybeans o attempt to “dress up organic to be more than what it really is” Fit for life: - Authors Harvey and Mary Diamond - “Greatest threat to your health is processed food. The day science entered the industry was a sad day.” - Attacked chemistry  “hydrogenated methyl chloride tree” - “within atoms and molecules, reside the vital elements we know as enzymes. Enzymes are not things or substances. They are the life principle in the atoms and molecules of every living cell.” o Purported the idea that enzymes are the living elements in food, and by processing them and using additives, we are destroying them o Nonsense!  Body produces its own enzymes  We don’t use enzymes from outside sources - “women must not have female orgasm during pregnancy because it cuts off the oxygen supply to the fetus and results in inferior brain development” o no scientific evidence - “there is only one body function that rivals the energy use of digestion and that is sexual activity. Overindulging in sex will bring on a toxic state.” o No scientific evidence o By eating the right way, you can still have sex safely o “nerve impulses don’t have to travel through a lot of muck and sludge to get to where they can register your pleasurable reaction if you are clean inside.” - Focus on combining foods in the right way  acid vs alkaline mediums to improve digestion Hippocrates diet - author: ann wigmore - “body enzyme energy at birth” o wrong  enzymes are constantly being produced by your body - “exercises for the colon” o sitting vs squatting Supplements: - cannot get enough nutrients from our food supply due to pesticides - people focus on polypharmacy story: Dominican republic - stands on the beach, selling branches and leaves - Mama-juana “mi don” curativa o “medicine…for everything” o Dosage: as much as you need o Good for sinusitis, ulcers, sexual problems etc. Historically: - Herbals  plants listed along with what they’re supposed to do o Ex. Egyptians, Sumerians (poppies = morphine) o Middle ages  herbalists = doctor o Apothecaries’ garden in London  plants in the garden were thought to have medicinal qualities  Autumn crocus-colchicine  grown for gout, arthritis  Different sections for different diseases (cardiology, oncology, dermatology) - Long history of plants as medicine - Still exists today many plant extracts sold Frequency of use of plant extracts/herbal remedy - 40% used within the last 12 months - 2.3 different herbs per person - Reason: “desire to improve general health”, “herbals are natural” - 40% used herbals before seeking medical help - 50% did not inform physicians that they were using herbals Composition of herbal remedies: - purple cone flower –Echinacea o Most widely sold herbal remedy in North America o History: 1800’s –one of the ingredients in Clark Stanley’s orginal snake remedy  People believed snakes were immune from aches/pains  If you can isolate the oil in snakes that makes them slither, you can use it as a cure  Snake oil –now a term to describe ineffective cures o Peop
