Choice among good options: Good for children
This article, from sensible Canada, reminds me of the wisdom of the inimitable Lisle V. Roberts, aka "Dad," who specialized in creating choice for his picky three-year-old eater: "Where would you like your lima beans?" he would ask. I got to choose the three beans' location on my plate, and (after he peeled them) I got around my suspicious nature enough to taste them.
I'm less sure about the focus on grains in this article (since I buy the notion that wheat, particularly, has been engineered into something a lot of us treat as alien once we ingest it) but I like the idea of making lots of good options available to children, and getting out of the food cop business.
