问题 【F1】A leaked study examining genetically-modified corn reveals that the lab-made alternative to organic crops contains a startling level of toxic chemicals.
【F2】An anti-GMO website has posted the results of an education-based consulting company’s comparison of corn types, and the results reveal that genetically modified foods may be more hazardous than once thought.
The study, the 2012 Corn Comparison Report by Profit Pro, was published recently on the website for Moms Across America March to Label GMOs, a group that says they wish to "raise awareness and support Moms with solutions to eat GMO Free as we demand GMO labeling locally and nationally simultaneously." They are plotting nationwide protests scheduled for later this year.
The report, writes the website’s Zen Honeycutt, was provided by a representative for De Dell Seed Company, an Ontario-based farm that’s touted as being Canadian only non-GMO corn seed company. "The claims that ’There is no difference between GMO corn and NON Gmo corn’ are false," says Honeycutt, who adds she was "floored" after reading the study. According to the analysis, GMO corn tested by Profit Pro contains a number of elements absent from traditional corn, including chlorides, formaldehyde and glyphosate.【F3】While those elements don’t appear naturally in corn, they were present in GMO samples to the tune of 60 ppm, 200 ppm and 13 ppm, respectively.
Honecutt says that the United States Environmental Protection Agency(FDA)mandates that the level of glyphosate in American drinking water not exceed 0.7 ppm and adds that organ damage in some animals has been linked to glyphosate exposure exceeding 0.1 ppm. "Glyphosate is a strong organic phosphate chelator that immobilizes positively charged minerals such as manganese, cobalt, iron, zinc and copper."【F4】Dr. Don Huber attested during a separate GMO study recently released, adding that those elements "are essential for normal physiological functions in soils, plants and animals". "Glyphosate draws out the vital nutrients of living things and GMO corn is covered with it." adds Honeycutt, who notes that the nutritional benefits rampant in natural corn are almost entirely removed from lab-made seeds:【F5】in the samples used during the study, non-GMO corn is alleged to have 437-times the amount of calcium in genetically modified versions, and 56-and 7-times the level of magnesium and manganese, respectively.
