Fattening Our Kids on GMO Foods

As if there were not already enough concern about the impact of GMO crops on agriculture and the environment, a new international study raises the worry that a diet including genetically modified ingredients may be contributing to obesity.

The effect of GM foods on rats, mice, pig and salmon is being studied by an international team from Hungary, Austria, Ireland, Turkey, Australia and Norway. In March they reported preliminary findings that found no negative metabolic changes in the pigs, salmon or mice they tested.

The results released in July link GM corn with modest weight gain in rats. The animals were fed corn with an insect-resistant gene. The control group ate unmodified corn. During the course of the 90-day study, the gm-fed rats gained more weight than the others.

Professor Åshild Krog Dahl cautions more study is needed but that if the impact on humans is similar, long-term consumption of genetically modified food or the meat from animals fed a GM diet could be contributing to the increase in obesity.

Although the study’s initial findings show no major negative health impacts, Professor Krog Dahl points out the need for more investigations. She says:

It has often been claimed that the new genes in genetically modified foods can not do any harm because all genes are decomposed beyond recognition in the intestine. Our results show the contrary that genes can be absorbed across the intestinal wall, transferred to the blood and are found in blood, muscle and liver in such large chunks that they can easily be recognized.

The researchers also found a slight impact on the immune systems of the rats who ate genetically modified food. For scientists, health effects such as those already revealed in the study are not yet alarming but suggest more research is needed.

For consumers, the precautionary principle suggests avoiding GMO ingredients until they have been proven safe rather than consuming them until their risks have been proven beyond a shadow of a doubt. Compelling reasons for caution are laid out by two genetic engineers in GMO Myths and Truths.

GM foods can work? Maybe meals prepared from scratch at home for GM workers at the truck/car assembly plants needing a good meal but as far as GMO food goes one has to be suspicious given all the problems with animals and even wildlife dying as a result of eating GMO crops in the fields.

Who knows what the long term effects on the human body will be and that of animals, birds and other wildlife? Not to mention animals on factory farms already given hormones and antibiotics added to the GMO crops they eat unlike the free range animals raised organically on a natural diet.


Simon says, don't worry to much, be trusting that GMOs can do good. If Monsanto is involved on has many doubts about that!


All of this is very unnerving and interfering with Nature's foods will result in many problems. At least if it is labelled people have the choice to avoid it.

I recently read that Monsanto & Cargill, are big among those trying to use the soy into a GMO "sustainable" food source (feed) for farm raised fish..... They may even be or start dumping it into our waters and oceanic aquaculture. There are so many big problems today that it takes many if not all of us in this site to participate and take action any way you can.
