Shit I have been reading lately is definitely pushing me back to Organic foods. Ate Organic (Ital) for about a lil over a decade then couple years back due to money and time constraints. Here is a little quote from the response section on one of these articles on GMOs..

Since the vast majority of processed foods contain GMO corn or soy, and since chicken and beef are fed GM corn, so that dairy and eggs come from animals raised on GM foods, and since even non-GM foods are often cooked in GM corn or soy oil, the only way to avoid regular exposure to GM foods in the US is to eat organic foods.
and here are some of the effects seen in test animals..

Studies showed stunted growth, impaired immune systems, bleeding stomachs, abnormal and potentially pre-cancerous cell growth in the intestines, impaired blood cell development, misshaped cell structures in the liver, pancreas and testicles, altered gene expression and cell metabolism, liver and kidney lesions, partially atrophied livers, inflamed kidneys, less developed organs, reduced digestive enzymes, higher blood sugar, inflamed lung tissue, increased death rates and higher offspring mortality as well
