Genetically Modified Food

Gene – A gene is the molecular unit of heredity of a living organism. It is used extensively by the scientific community as a name given to some stretches of deoxyribonucleic acids (DNA) and ribonucleic acids (RNA) that code for a polypeptide or for an RNA chain that has a function in the organism. Living beings depend on genes, as they specify all proteins and functional RNA chains. Genes hold the information to build and maintain an organism’s cells and pass genetic traits to offspring.

◾You are a tomato farmer whose crops are threatened by a persistent species of beetle. Each year, you spend large sums of money for pesticides to protect your crops. A biotechnology company introduces a new strain of tomato plant that produces a natural pesticide, making it resistant to the beetle. By switching to this new strain, you could avoid both the beetle and the chemical pesticides traditionally needed to fight it.

◾As a family physician, you often treat children who suffer from infectious diseases that could easily be prevented through vaccination. But the parents of many of your patients cannot afford the cost of vaccinations. You hear of a new approach that would reduce the cost to a fraction of its current price: genetically modified fruits and vegetables that contain various vaccines. By simply eating a banana, a child could be protected against disease—without getting a shot!

◾You are the leader of a developing nation. Hunger is a problem among your citizens: the salty coastal wetlands of your country can’t support the growth of needed crops, and your slow economy can’t support importing enough food for everyone. A biotechnology company has genetically modified a rice plant that can thrive in salt water, providing your nation with the opportunity to feed its citizens while bolstering its economy.

As you can see what the Utah education website had to say about what a modified food can do to the body. “By simply eating a banana, a child could be protected against disease—without getting a shot!” That’s just by eating a banana. What if someone eats more than the average person? What if Aunt Nana likes to eat her banana splits more than just once a day? What is happening in the body when we are consuming these foods?

Technology now allows us to transfer genes between organisms. For example, the tomato plant’s beetle resistance relies on a gene from a bacterium (Bacillus thuringiensis), which scientists inserted into the tomato plant’s genome. This gene, called cry1Ac, encodes a protein that is poisonous to certain types of insects, including the beetle.

Bacillus thuringiensis

From Wikipedia, the free encyclopedia

Bacillus thuringiensis (or Bt) is a Gram-positive, soil-dwelling bacterium, commonly used as a biological pesticide. B. thuringiensis also occurs naturally in the gut of caterpillars of various types of moths and butterflies, as well on leaf surfaces, aquatic environments, animal feces, insect-rich environments, and flour mills and grain-storage facilities.[1][2]

During sporulation, many Bt strains produce crystal proteins (proteinaceous inclusions), called δ-endotoxins, that have insecticidal action. This has led to their use as insecticides, and more recently to genetically modified crops using Bt genes. Many crystal-producing Bt strains, though, do not have insecticidal properties.

Toxicity

– B.t. is of low threat to humans because it does not persist in the digestive tracts of mammals. Classified as “slightly toxic,” the most common side-effects are skin and eye irritation.

Allergens trigger 75 percent of asthma cases:

Allergenicity is of particular concern because approximately 75 percent of asthma cases are triggered by allergens [9] and illnesses and deaths due to asthma have rocketed in recent years. Asthma deaths tripled in the United States from 1 674 in 1977 to 5 438 in 1998. The costs of asthma doubled from $6.2 billion in 1990 to $12.7 billion in 2000 [10].

Bt crops were first introduced in the United States in 1996, and have expanded substantially in acreage since, with little or no further research on the toxicity or allergenicity of the Cry proteins released in greater and greater abundance into the environment. Limited studies carried out by a research team in Cuba showed that Cry1Ac is a powerful immunogen, and when fed to mice, induced antibody responses similar to those obtained with the cholera toxin. Furthermore, Cry1Ac actively binds to the inner surface of the mouse small intestine, especially to the ‘brush border’ membranes on the cells lining the small intestine [11].

It has also been shown that all the Cry proteins in Bt crops have amino acid sequence similarities to known allergens [12-14], and are hence potential allergens.

A woman exposed to an B.t.k. formulation as a result of drift went to the hospital due to burning, itching-and swelling of her face and upper chest. She later exhibited a fever, altered consciousness, and suffered seizures.24 No B.t. was cultured from tissue samples, but her doctor believed that B.t. was the cause of the clinical symptoms.25

Low threat to humans, slightly toxic. That’s just from a tomato, which is supposed to be good for you.

‘….cows that ate Roundup Ready soybeans produced milk with more fat in it. In another example, milk from cows injected with a genetically engineered growth hormone was found by a number of researchers, including those published in the journal Lancet, to have substantially higher levels of a compound known as insulin-like growth factor-1, which is linked to human breast, colon and prostate cancers. The milk also has higher levels of bovine growth hormones in it, along with pus and sometimes antibiotics. GM crops have been linked to health problems as diverse as reproductive damage, cancer, Alzheimer’s disease and diabetes. Concerned scientists have been outspoken about these risks.’

I shouldn’t have read these articles. I have a burger on the frying pan right now, waiting to be flipped, then lightly padded with some tomatoes. The bad thing about these is that I can’t tell if the meat I’m eating was from a cow that was eating these genetically modified food, the same also goes to the fruits and vegetables I consume every day. Are they labeled?

Time will tell, if this food we eat is good for us. Or, maybe there are cases around the world right now, but we are not paying any attention. Maybe there are things that are happening in our bodies that we can’t yet notice…… But, until then, I’m going to go enjoy this genetically modified Cheese Burger, and look around youtube for some more info. Mmmm

I finished my food and then watched a video that I found on youtube. Titled ‘Seeds of Death’. It was Interesting, I used to brush off these type of videos before. There’s a guy at 56 min named Bruce Lipton, who talks about the RNA in food and in our own cells. I used to think that the body only takes what it needs from the foods we consume, then expels the rest. But, there is a lot more than that.

With our understanding of Evo gynetics, the new science of how environment signals control our genes. We’re introducing into the chemistry of where do the signals come from that select the genes that modify our genetic activity? Well, we used to say everything is due to the genes. But, now we find there’s a class of molecules called micro RNA. Their very small micro RNA molecules and they are found in all the cells. And these micro RNA molecules are molecules that adjust the reading of our genes, well a new understanding have been found on micro RNA molecules. When we eat food, the micro RNA from the food is picked up by the digestive system and not broken down. The micro RNA is taken in into our own body in tacked. And now what they found is the micro RNA from food ends up in our own cells, our liver and other cells in our body. These micro RNA’s still have the same function. They change our genetics and they change our read out of our Genome. And the significance is profound. It says when you eat genetically modified foods, we are eating a new class of micro RNA’s that never really have been in the world before. And yet these micro RNA’s are picked up by our biology and adjust our own genetics. So, in a sense the old story “We are what we eat” actually now has a biochemical foundation.
