Walk into just about any elementary school classroom in America and certain "things" are always there. Across the top of at least one wall is the alphabet. One wall is always given over to a collection of the latest papers and projects turned in by the students, somewhere a globe of the earth rests, and somewhere on a wall is the USDA nutritional pyramid chart. The charts is usually brightly colored with clipart drawings of the various food types.
Tomorrow morning the USDA will unveil their new "symbol and food guidance system" in response to criticism that the old daily nutrition guidelines have been a contributor to obesity in children.
Next week classrooms will start sporting this new chart. Changes that matter are often subtle, but definitely universal.
