Too Much Sodium Linked to High Blood Pressure, Experts Say
Nov. 29, 2007 -- A scientific watchdog group is asking the government to cut the amount of sodium Americans consume, while regulators consider whether such a move would have widespread health benefits.
The group is calling on the FDA to set new standards limiting the sodium content of food. Americans on average consume far more that the recommended amount of sodium, a fact thought to play a key role in high rates of hypertension and cardiovascular disease.
Most of the sodium Americans eat is from packaged food or restaurant meals. The group, the Center for Science in the Public Interest (CSPI), says voluntary industry efforts to curb the use of salt have not gone far enough. The CSPI petitioned the FDA to compel more cuts.
"We have a health crisis on our hands, and history suggests that more certain and more permanent measures are needed," Michael Jacobson, PhD, the group's executive director, said at FDA hearings on the petition.
Cardiovascular disease, including strokes, heart attacks, and heart failure, is the No. 1 killer of Americans. Hypertension, or abnormally high blood pressure, is a major risk factor for cardiovascular disease.
Cutting Sodium Levels
The hearings mark the first time in 25 years that the FDA has considered measures to cut sodium levels in food. The agency concluded in 1982 that voluntary industry efforts were sufficient to protect the public's health.
Americans' average sodium intake did not drop appreciably, while rates of cardiovascular disease have gone up.
"I think the FDA's optimism about voluntary changes has proved unwarranted ... and many tens of thousands of people have died unnecessarily," Jacobson said.
Agency officials called Thursday's hearing an information-gathering session and said they have not determined when or if they will move to curb sodium in the food supply. The agency could enact new limits on the amount of sodium companies can add to food or come up with stricter labeling standards warning consumers about the dangers of sodium.
"There is a lot of research for us to consider," Barbara Schneeman, PhD, director of FDA's office of nutrition, labeling, and dietary supplements, told WebMD.
