  • Natural and artificial flavors are made by chemists, called flavorists.
  • Benzaldehyde (almond flavoring) derived through a different process – by mixing oil of clove and the banana flavor, amyl acetate – does not contain any cyanide
  • 17 studies in humans and 223 studies of nutrient and contaminant levels in foods met inclusion criteria, but only three studies had clinical outcomes. Clinical outcomes were reactions, such as eczema, wheezing andatopicsensitization.They looked at pesticide levels in serum, urine, breast milk and semen and found no significant difference. Long term health effects have not been studied.

  • CHAPTER 12 Food Safety Nutrition HO-15
  • 48 million cases of foodborne illness 3,000 deaths annually
  • Microbes Infection Intoxication
  • E Coli O157:H7
  • bloody diarrhea severe intestinal cramping dehydration & even death
  • “You’d be better off eating a carrot stick that fell in your toilet than one that fell in your [kitchen] sink.” Charles Gerba, PhD
  • Keep hot food hot Keep cold food cold Keep raw food separate Keep your hands clean
  • Pesticides Control insects, weeds, diseases 4.5 billion lbs of pesticides/year Linked with birth defects, tumors in animals Effective?
  • Natural and Artificial Flavors Citromax Flavor
  • Spices Beef Veggies Chicken Fruits Herbs Yeast Natural Flavor Bark
  • Apricot pits Peach pits Bark Almond flavor + cyanide
  • Organic Foods and GMOs
  • Pros Cons Minimize pesticide exposure 25% of organics have pesticides Limits pesticide resistance High cost Benefits environment Not nutritional superior
  • “The published literature lacks strong evidence that organic foods are significantly more nutritious than conventional foods”. “Consumption of organic foods may reduce exposure to pesticide residues and antibiotic-resistant bacteria”.
  • GMO Pros GMO Cons Dwindling farmland Insects become resistant Medicine shortages Failure to confine Nutrient deficiencies Cross pollination Food shortages High cost to farmers
  • GMO Pros GMO Cons
  • Prop 37 Monsanto
  • THE Food Safety END
