There are two things that will make finger-wagging food cops go ballistic: sugar and salt. They may not use unnecessary force if you violate their food “laws,” but they do create unnecessary hysteria and, even worse, unnecessary regulation. For years, the food police have been warning that salt (of all things) is a silent killer. And now, based on a new move by U.S. government agencies, our food could soon be a little blander at their behest.
