(BeWellBuzz) The first lifetime feeding study assessing the health risks of GM foods has confirmed that genetically engineered foods are harmful. The results of this 2-year long study were published online on 19th September.
In the study, rats were fed genetically engineered corn that is being sold in the US for last two years. Scientists found that rats that were fed genetically engineered corn, the test group that is, developed tumors and many other serious health problems.
The scientists made the following observations:
- Mortality rate of female rats in all treated groups was significantly higher than the subjects in the control group
- The mammary glands in females that were fed genetically engineered cord developed faster than subjects in the control group. Also, the size of the mammary gland in female rats in all treated groups was bigger than those in control groups
- The hormonal balance in females in all treated groups was altered
- Male rats in all treated groups recorded up to 5.5 times higher instances of necrosis and liver congestion
- Male rats that were fed genetically engineered corn recorded up to 2.3 higher instances of severe kidney nephropathies
- Male rats in target groups recorded significantly large number of tumors than rats in the controlled group
- Both male and female rats in all treated groups recorded substantial kidney chronic deficiencies
The average life expectancy for Americans is approximately 80 years. Rats, on the other hand, live for only 2 to 3 years. So, it is natural that the effects of GM-foods are visible in rats long before they start appearing in humans. GM foods are only a decade old. According to experts, it will be many years before we see the proof of harmful effects of GM foods on humans.
Animal studies have consistently demonstrated the dangerous effects of GM foods. The effect of GM foods on humans cannot be seen right now because we have not been eating these foods for long enough. So, what should we do? Do we wait until the negative effects of GM foods start appearing in humans, which can be decades from now?
Animal studies, this two-year long study being the latest one, suggest that we handle the issue of GM foods now. If we wait, it may just be too late.
Biotech companies’ claim that GM foods are safe is a weak one
In their defense, the biotech companies mention various peer-reviewed studies and other studies that have found GM foods to be safe.
It is true that hundreds of peer-reviewed scientific studies, including many feeding studies, have found GM foods to be safe. However, what is also true, and of utmost concern, is that all these studies, including the feeding studies cited by biotech companies, inexplicably had too short a time frame to record any abnormalities.
All studies cited by biotech companies were small-term studies, the longest lasting just 90 days. While the adverse effects of GM foods on rats in all longer studies were not recorded until a few months. In long-duration studies, such as the aforementioned two year study, the real onslaught of diseases happened from the 13th month onwards, although male rats started showing signs of severe kidney and liver damage from the fourth month itself. In the case of females, signs of kidney and liver damage were seen as early as in the sixth month.
With damaging effects of GM foods taking at least 4 months to surface in animal subjects, it is no wonder then that the 90-days long feeding studies did not record any harmful effects of GM foods. Maybe these studies were not meant to record any harmful effects and that is why they were completed so quickly.
