That's not even true any more with all the GMO being used in our food supply and poor treatment of the soil. It's gotten to the point where you have to buy from someone you trust or grow everything yourself to know what you're truly eating.
I almost to late to grow ur own or buy local. Cargill, Monsanto, ADM have been buying up every seed company they can find. It's amazing how many patents these companies have for just corn. GMO corn has been proven to cross contaminate unmodified varieties. Then they can claim the farmers are stealing there GMO corn. They force farmers to buy their seeds and those crops only work with the GMO inputs. The terminator genes that Monsanto used in some tomato varietals. It's a mess. Ur right man this is bad! Food is like UGL gear, we don't know what we are putting into our bodies and it's scary!
