The researchers from the U.S. Centers for Disease Control and Prevention examined nearly 4,000 product labels from three different regions.
The investigators examined 10 packaged grocery items for the salt content.
“We looked at bread, cold cuts, pizza, poultry, soup, sandwiches, cheese, pasta-mixed dishes, meat-mixed dishes and savory snacks,” said Linda Scheib, an epidemiologist with the center’s Division for Heart Disease and Stroke Prevention.
Ten percent of the snack food, breads and cheese exceed the threshold. Food that is generally considered healthy like the bread is the number one contributor for salt.
Scheib said, “A lot of foods that people don’t think taste salty do actually have a lot of sodium in them, so, we recommend people just read those nutrition labels, make comparisons, try to choose lower sodium options, be sure to eat more fresh fruits, vegetables and meats and cook more at home because that way you have more control over the amount of sodium.”
Prepared meals should contain less than 600 milligrams of salt and the individual food must contain less than 480 milligrams of salt.
2,200 milligrams or one teaspoon of salt per day is recommended and for the people suffering from kidney disease, heart disease and high blood pressure their daily intake of salt should be less than 1,500 milligrams.
The findings are published in journal Preventing Chronic Disease.
