A conversation with Charles Platkin at 12:30 p.m. on The Wisdom of 90 Years: Dr. Marion Nestle on Food and Living Your Best Life. Registration is here.

Parke Wilde, a professor at Tufts who writes a blog on food policy, has just sent me his analysis of food companies’ attempts to self-regulate the way they market junk foods to children. As he puts it, self-regulation is at a “critical juncture.” Translation: the voluntary system isn’t working very well. Food companies, he suggests, must do a better job or expect others to do it for them.
