I recently received an email with the subject line: "A well-balanced diet consists of a taco in each hand … on the beach (can’t forget that vitamin D)." The line was memorable and highlighted the fact that modern consumers have some novel ideas about what constitutes a healthy diet.

The dairy industry has long touted that “milk contains nine essential nutrients.” And while the nutritional content of milk, cheese and yogurt hasn’t changed, the claims that the industry can make about dairy will be modified in some important ways by the new Nutrition Facts regulations.
