In the United States, more than 40% of sodium people eat comes from the following 10 types of processed foods:9

  1. Deli meat sandwiches
  2. Pizza
  3. Burritos and tacos
  4. Soups
  5. Savory snacks, such as chips, popcorn, pretzels, snack mixes, and crackers
  6. Poultry
  7. Pasta mixed dishes
  8. Vegetables
  9. Burgers
  10. Eggs and omelets

Most of the sodium you eat comes from processed foods (e.g., hot dogs, sausages, ham, luncheon meats) and restaurant foods. You can’t control the amount of sodium in these foods, so it’s important to limit them in your diet.7

“Processed food” includes food that has been cooked, canned, frozen, packaged, or changed in nutritional composition by fortifying, preserving, or preparing it in different ways.8

To learn how much sodium a processed food has, check the Nutrition Facts label. The sodium content is listed in milligrams.10

What is the difference between sodium and salt?

Sodium, which is a mineral, is an element found in salt.11 The chemical name for salt that you eat or drink (e.g., salt in the saltshaker) is sodium chloride.5 The terms are not the same but are often used interchangeably, and both may appear on a food label. For example, the Nutrition Facts label uses “sodium,” while the front of the package may say “salt free.”12

What do the different sodium-related terms mean on food packages?

  • Sodium free—contains less than 5 mg of sodium per serving and no sodium chloride
  • Very low sodium—contains 35 mg of sodium or less per serving
  • Low sodium—contains 140 mg of sodium or less per serving
  • Reduced sodium—contains at least 25% less sodium per serving than usual
  • Light (for reduced sodium products)—the food is “low calorie” and “low fat” and sodium is reduced by at least 50% per serving
  • Light in sodium—sodium is reduced by at least 50% per serving13

What does “salt sensitive” mean? Who is “salt sensitive”?

When a person is salt sensitive, their blood pressure goes up more than usual when they consume sodium.5

People with salt sensitivity often are older, are Black, and/or have high blood pressure, diabetes, or chronic kidney disease.5 There is no screening test for salt sensitivity.
