An open letter to Michael Bloomberg, Mayor of New York
On January 11 of this year, you announced an ambitious program dubbed the "National Salt Reduction Program." This program was patterned after the Food Standards Agency salt reduction program in the UK, which you characterized as a success. Considering the economic, social and infrastructural problems that New York City faces, you clearly believe that a population-wide reduction of salt intake is a very high priority issue. Yet, the issue of population-wide salt reduction remains deeply mired in controversy. The majority of meta-analyses on the subject do not conclude that population-wide salt reduction is warranted. Some even state that there may be an unintended consequence resulting from such an action.
As you are so devoted to this program, I believe that you should have an opportunity to openly demonstrate the depth of this commitment. It would certainly not be the first time that political leaders have stood up to demonstrate the courage of their convictions. In 1991, in an effort to stave off international criticism regarding Peru's polluted fishery, President Alberto Fujimori dined on local ceviche in front of news cameras to demonstrate his faith in the quality of their fish. It is of no consequence that he came down with cholera the next day - the important thing is he had the courage to stand up for what he believed in.
As a public leader, I feel that you should have the same opportunity and hope that you would demonstrate the same degree of courage. I propose that you go on a 1,500 mg sodium/day diet, as recommended by the CDC and I will maintain my 3,500-4,500 mg sodium/day level for a full month. During that time, we should have our blood chemistry (renin, aldosterone, cortisol, etc.), blood pressure, arterial pulse wave velocity (a measure of arterial stiffness) and urinary sodium levels checked weekly. I would further invite Drs. Larry Apell, Chairman of the Dietary Guidelines Sub-Committee on Electrolytes and Michael Jacobson of the Center for Science in the Public Interest, two individuals who have repeatedly stated that humans do not require more than 500 mg of sodium/day to join in this demonstration by consuming that 500 mg sodium/day for one month as well and undergo the same tests.
Finally, I propose that Dr. Mehmet Oz use his good facilities to manage the clinical tests and report the results on his television program.
Mr. Mayor, I have no doubt that you wish to do what is right. I do as well, however, we are operating from a totally different set of peer-reviewed data. A task as simple as the one I suggest may well resolve this issue to everyone's satisfaction and will set the salt and health debate upon a course that should benefit all citizens.
Yours sincerely,
