The most popular genetically engineered (GE) crops planted on millions of U.S. acres each year are designed to withstand heavy dousing of glyphosate. Chemical companies are making a killing on this, since they produce both the unnatural GE seed and the chemical that needs to be used on those seeds. But glyphosate is a systemic chemical, meaning its taken up inside of the plants that weand farm animalseat. This spring,Norwegian scientists studying U.S. soy found excessive levels of glyphosate inside of the food crop. Dont eat tofu? Doesnt matter: GE corn and soy fall under dozens of different ingredient names in most processed foods.

The study authors theorize that glyphosate disrupts the normal functioning of white blood cells, throwing your immune system into a sickened, dysfunctional state.

3. Its raining Roundup. Each year, nonorganic farmers dump millions of pounds of glyphosate on food crops. The levels are so excessive, that the federal scientists recently detected the weed killer in the air and rain. Veteran pesticide-exposure scientist Warren Porter, PhD, professor of environmental toxicology and zoology at the University of WisconsinMadison, crunched the numbers and found the data collected by the United States Geological Survey scientists reveal exposure that could potentially alter your hormones, leading to obesity, heart problems, and diabetes.
