Love this article from Keeper Of the Home.
She has done a beautiful job with links and back up information.
Take a moment, and take to heart what she says...do what you can to fix your family's food, but keep the joy. I am paraphrasing. She says it better.
You don't have to be perfect.
Don't stress out about it.
Make informed choices.
Our food is barely real food anymore, and our health reflects that.
Make some baby steps.
This article is a good place to start.
And her book sounds amazing!
