Part 1: Documentary on Genetically Modified Food from UK


Weight Loss Tip: Don't skip meals. Skipping meals is one of the biggest mistakes anyone trying to lose weight can make. Skipping meals not only deprives your body of precious energy it could be using to workout, it also messes with your metabolism. Instead of skipping meals, plan healthy ones full of nutrients.

Genetically modified foods (or GM foods) are foods derived from genetically modified organisms. Genetically modified organisms have had specific changes introduced into their DNA by genetic engineering techniques. These techniques are much more precise[1] than mutagenesis (mutation breeding) where an organism is exposed to radiation or chemicals to create a non-specific but stable change. Other techniques by which humans modify food organisms include selective breeding; plant breeding, and animal breeding, and somaclonal variation.
GM foods were first put on the market in the early 1990s. Typically, genetically modified foods are transgenic plant products: soybean, corn, canola, and cotton seed oil. Animal products have also been developed, although as of July 2010 none are currently on the market.[2] In 2006 a pig was controversially[3][4] engineered to produce omega-3 fatty acids through the expression of a roundworm gene.[5] Researchers have also developed a genetically-modified breed of pigs that are able to absorb plant phosphorus more efficiently, and as a consequence the phosphorus content of their manure is reduced by as much as 60%.[6]

Method
”Genetic modification involves the insertion or deletion of genes. In the process of cisgenesis, genes are artificially transferred between organisms that could be conventionally bred. In the process of transgenesis, genes from a different species are inserted, which is a form of horizontal gene transfer. In nature this can occur when exogenous DNA penetrates the cell membrane for any reason. To do this artificially may require transferring genes as part of an attenuated virus genome or physically inserting the extra DNA into the nucleus of the intended host using a microsyringe, or as a coating on gold nanoparticles fired from a gene gun. However, other methods exploit natural forms of gene transfer, such as the ability of Agrobacterium to transfer genetic material to plants, and the ability of lentiviruses to transfer genes to animal cells.
Development
The first commercially grown genetically modified whole food crop was a tomato (called FlavrSavr), which was modified to ripen without softening, by Calgene, later a subsidiary of Monsanto.[8] Calgene took the initiative to obtain FDA approval for its release in 1994 without any special labeling, although legally no such approval was required.[9] It was welcomed by consumers who purchased the fruit at a substantial premium over the price of regular tomatoes. However, production problems[8] and competition from a conventionally bred, longer shelf-life variety prevented the product from becoming profitable. A tomato produced using similar technology to the Flavr Savr was used by Zeneca to produce tomato paste which was sold in Europe during the summer of 1996.[10][11] The labeling and pricing were designed as a marketing experiment, which proved, at the time, that European consumers would accept genetically engineered foods. Currently, there are a number of food species in which a genetically modified version exists
In addition, various genetically engineered micro-organisms are routinely used as sources of enzymes for the manufacture of a variety of processed foods. These include alpha-amylase from bacteria, which converts starch to simple sugars, chymosin from bacteria or fungi that clots milk protein for cheese making, and pectinesterase from fungi which improves fruit juice clarity.

  1. Poor kid. You do realise one of the reasons you get bored so easily and
    can’t comprehend the importance of this subject is probably because your
    brain is being retarded by all the GM food that you’re eating without even
    knowing it. For your sake (and your children’s if you choose to have them)
    take these matters more seriously. Good luck and all the best.

  3. Its disappointing to have this stuff even BE our food to begin with. Why.
    Just why. There are obviously unfavorable effects. I DONT WANT TO BE AN
    EXPERIMENT. All of these unhealthy foods with fats and oils and fast food
    meats.. Ever consider maybe its not just the developed world’s increasing
    sedentary lifestyles causing health complications such as diabetes BUT ALSO
    the use of GMOs? It’s probably just an excuse for big corporations so we
    can be distracted and not the underlying issue.

  4. most of australia is uninhabitable desert… thats why nobody lives out in
    its centre, its literally just sand 

  5. Scorpion cabbage? Round up weed killer ready soy and corn? The great rise
    in allergies and sicknesses in the last decade? I want this stuff banned or
    labeled at least.We have no rights in the USA.We are owned by giant
    corporations.

  6. Who should at least be beaten or more… responsibles, politics, farmers,
    lobbyist, shareholders – or consumers, paying for crap food, opening their
    hungry mouth widely, swallowing “jummie GM foods”, letting themselves feed
    to sickness or death. Welcome to Guinea pig club… Long live good old
    mobile free times, abeling people to think and react properly by their own.
    Viva former revolutions…

  7. To HTHAMMACK1 + Fritzli bürli People have been eating GMO corps for 20
    years with no negative health effects whatsoever.

    Well, HTHAMMACK1, you don’t say Mr. Brainiac! Anyhow, I presume (almost)
    everbody (with a well-functioning brain), that nothing comes from nothing.
    Perhaps that’s why I guess, you have been consuming healthful GMO stuff for
    a very long time…

    Enjoy your health-meals – together with the circumstance of not risking too
    much, when lack of brain seems to taken over, while beeing (at least!) two
    steps ahead of any comprehension and understanding…

    Nevertheless LOVE, PEACE and MERCI, for all liar liars, rednecks incl. a
    new?! world’s order GMO section prepared to be very precisely. Cheeerio!

  8. ENGLAND and the rest of the world needs to stop eating this food and say
    YES to self government and self reliance and VICTORY gardens and small
    plots of land for all people and control of what one feeds themselves as
    well as family … even in apartments people can grow vegetables, herbs, as
    well as make your own baby formula … IT IS SO doable in many peoples
    lives and fun !!! EVERY school needs to have a victory garden and also
    give lessons to the kids and youth about growing their own foods and
    gardening … aka jungle gardens and wild produce … GO BACK to good old
    school values EVERYONE!

  9. since embarking on a strictly organic diet..my wife’s Diverticulitis has
    not flared up in over four months! so ends the inflammations caused by the
    dreaded..Glyphospates in Round Up!
