Transcript of How Genetically Modified Foods Affect Our Society

How Genetically Modified Foods Affect Our Society and Health
What Is Genetically Modified Food?
Large percentages of sugar cane, canola, and sugar beets are genetically modified. GM crops serve as feed for the majority of our country’s livestock.
What role do Genetically Modified Foods play in our Society?
Soybean and corn seeds that have been genetically modified make up 90% and 80% respectively of the total seeds on the market!
How do they affect our health?
Interesting Facts and Opinions
"Rats fed GM potatoes had smaller livers, hearts, and brains, damaged immune systems, and showed structural changes in their white blood cells making them more vulnerable to infection and disease compared to other rats fed non-GMO potatoes. It gets worse. Thymus and spleen damage showed up; enlarged tissues, including the pancreas and intestines; and there were cases of liver atrophy as well as significant proliferation of stomach and intestines cells that could be a sign of greater future risk of cancer. Equally alarming, results showed up after 10 days of testing, and they persisted after 110 days which is the human equivalent of 10 years" (Lendman, 2008)

Genetically modified foods are foods derived from genetically modified organisms or GMO’s. GMO’s have had changes introduced into their DNA by genetically engineering techniques. Genetically engineered plants are made in a laboratory and are tested for desired qualities. GMO’s are engineered to grow faster, resist pathogens, and produce extra nutrients.
What are they used for and in?
60% to 70% of all processed foods in the U.S. have genetically modified ingredients in them.
About 90 million metric tons of GM corn grains are produced worldwide and of that 70% goes to livestock feed.
That's a lot of GMO's!
Positive Affects
Negative Affects
GMOs allow crops to be grown in environments where they could not be otherwise
GMOs make easier farming with resulting cheaper food prices making it easier to feed populations worldwide
Chemicals like Monsanto's Roundup can be sprayed on fields and kill off all unwanted plants while leaving the GMO crop
GMOS can result in foods with higher nutritional value, one example being much higher amounts of vitamin A contained in genetically modified rice
No long term studies of GMO effects on humans have been done
Feared possible health risks are allergen exposure, antibiotic resistance, endocrine disruption, reproductive disorders, tumors and accelerated aging
No GMO labeling or testing is currently required by the Food and Drug Administration (FDA) which limits consumers' knowledge of whether their food was bioengineered. 50 countries require GMO labeling.
With that being said, supporters say GMOs could help solve world hunger by providing more efficient crops that can grow in less ideal climates or soils.
Adversely changing the nutrient content of a crop
Creation of "super" weeds and other environmental risks
Drought tolerance
Increased pest and disease resistance
A man by the name Pusztai conducted an experiment on rats who ate just genetically modified foods, the results were shocking...
Thanks for watching!
