Truth be told, there really is no clarity to what food is really about in the US. It seriously takes a determined effort to tease out the truth regarding food production and real nutritional benefit of the commodities that are being offered to the US public under the guise of "food". Now, don't everone get in an uproar over what I'm saying. Just do your own research as to what constitutes real nutrition, what you eat and what is involved in the production of that food regarding it's affects on your body and your health. Maybe then, when the average consumer becomes more educated to the fact that there is a problem, we all can have real talks about the food policies that dictate what we eat and what are food markets are doing.
In the meantime, remember two things: 1) I, Elaine Parny, wrote this blurp and 2) do your own research. It's easy, especially with the use of the internet.
As usual, here are a few links to get you thinking. Bon Apetit!
