I have yet to experience kidney stones and, knock on wood, pray I never will. A friend has been experiencing them this past week and because of that I Googled "kidney stones and diet" with many results.
One site listed 10 trigger foods to avoid and what was most telling was food item number 10 on the list. Genetically moified ingredients GMO's. It went on to state that "most processed foods....contain genetically modified ingredients—such as corn, soy, rice, and canola—to protect crops from pests resistance and herbicides. However, these products impair healthy kidney and liver function, encouraging kidney stones to form."
Why the FDA, the AMA and the CDC allow GMO's in American foodstuffs, against the wishes of The People, is mind-boggling and unethical!
