- can insert a gene from a bean that codes for ferritin , an iron storage protein - beans are rich in iron because they can suck it from soil; GMO rice can then do the same - cabbage has indole-3-carbinol , an anti-carcinogen - put cabbage gene into potato so potato can create indole-3-carbinol - can insert a gene that allows plants to adapt to dry soil - trans fats raise cholesterol - can create low linolenic acid soybeans à no trans fat & used at high temps for frying - normal veg oils can’t be used for frying bc they break down/oxidize at high temps - trans fat are often used bc they stand up to high heat - like trans fat, linolenic acid is less prone to oxidation à less need for hydrogenation - hydrogenation used on ordinary veggie oils to convert them to frying oils - papaya (big crop in Hawaii) can get Papaya Ring Spot Virus - GMO papaya can be resistant to it - GMO Arctic Apple does not go brown easily (used because kids don’t like brown apples) - take gene from apples that naturally don’t brown & insert them into apples that do - GMO potatoes with less black spots that also produce less acrylamide (natural toxin that forms when foods with carbs & asparagine are heated to a high temp) - these potatoes use genes only from other potatoes, but they still have to be called “GMO” Video 4 - “precautionary principle”: proof of no harm before introducing product of novel technology - a demand that science can’t meet - can’t prove that something will never cause harm; can just make educated guesses - with zero risk mentality we would have to reject all grain crops bc they are commonly contaminated with fungi, rodent droppings & insect parts - labeling requirements should be based on food content, not on the way it’s produced - labeling required for any GMO that is nutritionally or compositionally different from its traditional counterpart - 4 main GMO crops: corn, soy, canola, sugar beets - every 3.5 seconds someone dies from hunger à GMO risk vs. benefit to feed the hungry - Pontifical Academy of Sciences (Catholic Church) à scientists have a right & moral duty to be “stewards of god” by genetically modifying crops to help the world’s poor - Conventional cross breeding is limited to the incorporation of characteristics from related species Topic 6: Food Additives Topic 6: Lesson 1: Food Additives 1 Video1 - billboard “Made with no caffeine, sodium or scientists”, but scientists make sure our food is safe! - “Une cire toxique sur les fruits et legumes” - beeswax , carnauba wax (used in shoe polish), candelilla wax , shellac are added to some fruits - when apples are washed to eliminate pesticide residue, the natural wax is washed away - wax coating added to replace natural wax removed during washing & to prevent moisture loss - morpholine in wax converts to nitroso-morpholine - in v high amounts nitroso-morpholine might be carcinogenic to test animals
