Packaged Grocery Foods Often High in Salt, Study Finds

THURSDAY, April 2, 2015 (HealthDay News) — More than half of packaged grocery store foods included in a new study contained too much added salt, U.S. health officials reported Thursday.

That’s important because eating too much salt (sodium) is a risk factor for developing high blood pressure, according to the study authors. And high blood pressure can contribute to heart disease and strokes.


“We looked at packaged food sales in grocery stores,” said study researcher Linda Schieb, an epidemiologist in the division of heart disease and stroke prevention at the U.S. Centers for Disease Control and Prevention. “What we found was more than 50 percent of those products exceeded the FDA healthy food label guidelines for sodium.”

Under the U.S. Food and Drug Administration healthy food label guideline, only 480 milligrams (mg) of sodium per serving are allowed for individual foods — such as cheese, cold cuts and bread — to use the “healthy” label claim, Schieb said. And, 600 mg is allowed for meals, such as pasta dishes, pizza and sandwiches.

Schieb’s team analyzed product sales from 2009 for U.S. grocery stores from 52 markets in three of nine U.S. census divisions, which represents about half the country’s population. The researchers didn’t include warehouse stores or Walmart, according to the study.

The investigators found that more than 70 percent of pizza, pasta mixed dishes or meat mixed dishes (such as meat loaf or pork with BBQ sauce), as well as 50 to 70 percent of cold cuts, soups and sandwiches surpassed the FDA “healthy” labeling for sodium.

But only 10 percent of breads, savory snacks and cheese went over the healthy label guidelines, according to the report.

The researchers didn’t find any significant differences between the markets studied with regard to sodium content in foods.

The study is published in the April issue of the journal Preventing Chronic Disease.

Under the current U.S. Dietary Guidelines for Americans, the general population is advised to keep daily salt intake under 2,300 milligrams, or about a teaspoon. For people over 51, African-Americans and those with health conditions such as high blood pressure, diabetes or chronic kidney disease, the recommended daily sodium intake is 1,500 mg or less.
