Recently, I was in a discussion with people about our decision to grow our own vegetables, fruit and our chicken coop. I explained that our decision (I should say my wife's push), was centered around knowing where our food came from and knowing that all of our food is organically grown without any chemicals.
One of the people I had the discussion with mentioned a recent study that found corn was the main chemical component found in all fast foods. It took me a while but I finally tracked down the article, it really is quite interesting. The source can be found here: http://www.pnas.org/content/105/46/17855.full.pdf+html
There is a great movie about corn in all foods, it is called King Corn. You can view it online here:
Corn? If I am going to eat corn, I would rather eat it boiled in water with a slab of buttered melted on it.
My curiosity didn't stop there. In my research I found that the meats that were not raised on corn or soybeans were raised on eating plant combination's (often with corn) or animal byproducts! If you get squeamish, don't read this one: http://www.seattlepi.com/local/158359_feed28.html
You can eat the products derived with corn or meat raised on byproducts, I'll stick with our garden or locally grown vegetables.
