If the effort is successful, most Americans won't even notice the change. The idea is to lower sodium levels gradually so consumers' taste buds can adjust, and to give the industry time to develop lower-sodium food. Voluntary guidance proposed by the Food and Drug Administration sets two-year and 10-year sodium targets for around 150 categories of food.
It's the first time the government has recommended such limits. Sodium content already is included on existing food labels, but the government has not previously set specific sodium recommendations.
Things for consumers to know about the new guidelines -1. You probably eat too much salt
Health officials from the FDA and the Centers for Disease Control and Prevention say 9 out of 10 Americans are eating too much salt. The recommended amount is 2,300 milligrams a day, or about a teaspoon. But most people eat closer to 3,400 milligrams a day. That number has stayed steady over the years.
The government says overwhelming scientific evidence shows that blood pressure increases when sodium intake increases, upping the chances of heart disease and stroke. Most of that sodium is hidden inside common processed foods and restaurant meals, making it harder for consumers to control how much salt they eat.
2. From soups to donut to deli meat
The new targets cover a wide variety of processed and packaged foods. The guidelines propose average sodium amounts for categories of food and also upper limits for individual foods.
For some foods levels of sodium can vary widely. According to the CDC, sodium in a slice of white bread ranges from 80 milligrams to 230 milligrams. The new guidelines are designed to encourage more consistency, and for companies to aim for the lower ranges.
When lowering sodium levels, companies say that in some cases, just removing added salt or switching ingredients does the trick. Potassium chloride can also substitute for common salt (sodium chloride), though too much can cause a metallic taste.
In addition to flavor, companies use sodium to increase shelf life, prevent the growth of bacteria or improve texture and appearance. That can make it more difficult to remove from some products.
3. Dines may not taste the change
While those companies have touted their reductions, others have kept them quiet, fearing consumers may think their foods don't taste as good.
The food industry has lobbied against the guidelines, noting companies are already making changes. Leon Bruner of the Grocery Manufacturers Association, an industry group, said Wednesday that companies will work with the FDA on the guidelines and will ensure the agency is using the most recent science. FDA officials say they expect companies to eventually comply.
Guidelines Coming for a Long Time
The guidelines were delayed for several years amid the backlash from the food industry. The FDA first said it would issue voluntary guidelines in 2010, after an Institute of Medicine report said companies had not made enough progress on reducing sodium and advised the government to establish maximum levels for different foods. The FDA decided to go with a voluntary route instead.
In the meantime, the institute issued another report in 2013 that said there is no good evidence that eating sodium at very low levels — below the 2,300 milligrams a day that the government recommends — offers benefits. The food industry touted that report.
Some companies have worried that the guidelines are more warning than suggestion. But the wait means that Obama administration officials probably won't be around to see if individual companies follow the guidelines. A new administration will be likely be tasked with making them final, as they could take a year or more to complete.
Some Think They Should be Mandatory, Others Don't Like Them At All
Health groups have argued for mandatory standards, but say voluntary guidelines are a good first step. Michael Jacobson, the head of the Center for Science in the Public Interest, says the government should assess how the voluntary standards work and set mandatory targets if they don't.
The guidelines could face some backlash in Congress. Republicans have already fought the Obama administration over efforts to require calorie labels on menus and make school lunches healthier. And at least one group is totally opposed to the guidelines: The American Salt Institute. The group says lowering levels could be harmful if people don't get enough sodium.
"Americans should be extremely skeptical," the group said in a release.(This story has not been edited by NDTV staff and is auto-generated from a syndicated feed.)
