CDC: Most Adults Consume Too Much Sodium

ATLANTALess than 10 percent of U.S. adults limit their daily sodium intake to recommended levels, according to a new report, "Sodium Intake in Adults United States, 2005-2006," published today in the Center for Disease Control's (CDC) Morbidity and Mortality Weekly Report. The report also finds that most sodium in the American diet comes from processed grains such as pizza and cookies, and meats, including poultry and luncheon meats.

According to the report, U.S. adults consume an average of 3,466 mg of sodium per day, more than twice the current recommended limit for most Americans. Grains provide 36.9 percent of this total, followed by dishes containing meat, poultry and fish (27.9 percent). These two categories combined account for almost two-thirds of the daily sodium intake for Americans.

An estimated 77 percent of dietary sodium comes from processed and restaurant foods. Many of these foods, such as breads and cookies, may not even taste salty. "Sodium has become so pervasive in our food supply that it's difficult for the vast majority of Americans to stay within recommended limits," said Janelle Peralez Gunn, public health analyst with CDC's Division for Heart Disease and Stroke Prevention and lead author of the report. "Public health professionals, together with food manufacturers, retailers and health care providers, must take action now to help support people's efforts to reduce their sodium consumption."

The 2005 Dietary Guidelines for Americans recommends that people consume less than 2,300 mg of sodium per day. Specific groups, including persons with high blood pressure, all middle-aged and older adults and all blacks, should limit intake to 1500 mg per day. These specific groups comprise nearly 70 percent of the U.S. adult population. This study found that only 9.6 percent of all participants met their applicable dietary recommendation, including 5.5 percent of the group limited to 1,500 mg per day and 18.8 percent of the 2,300 mg per day group.

The report examined data for 20052006 from the National Health and Nutrition Examination Survey (NHANES), an ongoing study that explores the health and nutritional status of adults and children in the United States. Researchers used information from 24-hour dietary recall and the USDA National Nutrient Database to estimate the daily sodium intake and sources of sodium intake for U.S. adults.
