Sodium gets a lot of attention, but cutting back is not as simple as putting away the salt shaker.
In fact, most of the sodium Americans eat is already in packaged and prepared foods before the food reaches the table.
That makes the Nutrition Facts label one of the most useful tools for keeping sodium in perspective.
Here is how to use it without turning every meal into a math problem.
The Short Version
- The Daily Value for sodium is less than 2,300 mg per day.
- Americans consume about 3,400 mg per day on average.
- More than 70% of dietary sodium comes from packaged and prepared foods.
- 5% Daily Value or less per serving is considered low in sodium.
- 20% Daily Value or more per serving is considered high.
- Serving size matters: eating two servings means getting twice the listed sodium.
- You do not need to eliminate sodium. The goal is to make lower-sodium choices more often.
How Much Sodium Should You Get?
Sodium is an essential nutrient. Your body needs a relatively small amount to help maintain fluid balance and normal nerve and muscle function.
The problem is usually not getting too little.
According to the U.S. Food and Drug Administration's sodium guidance, the Daily Value is less than 2,300 mg per day for adults and children ages 4 and older.
For perspective, Americans currently consume about 3,400 mg per day on average.
That difference can add up over time. Diets higher in sodium are associated with higher blood pressure, an important risk factor for cardiovascular disease.
A newly published 2026 systematic review and meta-analysis of 23 randomized controlled trials also found that sodium-reduction interventions lowered home systolic and diastolic blood pressure, with larger effects in populations with hypertension.
That does not mean everyone needs an extremely low-sodium diet. Individual needs can vary, especially with heavy sweating, certain medical conditions, or medications.
For most people, however, the useful target is simply to avoid routinely exceeding the recommended limit.
Where Does All That Sodium Come From?
The salt shaker is the obvious suspect, but it is not the main source.
The FDA estimates that more than 70% of dietary sodium comes from packaged and prepared foods.
That can include foods that do not even taste particularly salty:
- Bread and baked goods
- Sauces and condiments
- Soups
- Deli meats
- Cheese
- Frozen meals
- Snack foods
- Restaurant meals
This is why simply avoiding obviously salty foods does not tell you much about your total intake.
The label does.
The Easiest Way to Read Sodium on a Food Label
You do not need to memorize milligrams for every food.
Use % Daily Value (%DV) instead.
The FDA's Nutrition Facts guidance gives a very simple rule:
5% DV or less per serving = low
20% DV or more per serving = high
Suppose two similar soups contain:
Soup A: 180 mg sodium — 8% DV
Soup B: 690 mg sodium — 30% DV
You do not need to decide that Soup B is a “bad food.” But if soup is something you eat frequently, choosing the lower-sodium option most of the time can make a meaningful difference.
That is what the label is best at: comparison.
Do Not Forget Serving Size
There is one catch.
Nutrition Facts numbers usually apply to one serving, not necessarily the whole package.
If a food contains 400 mg of sodium per serving and you eat two servings, you consumed 800 mg.
The same applies to %DV.
A product showing 15% DV per serving becomes 30% if you eat twice the listed serving.
This sounds obvious, but it is one of the easiest ways to underestimate sodium in snacks, soups, sauces, and packaged meals.
“Low Sodium” vs. “Reduced Sodium”
These phrases do not mean exactly the same thing.
A food labeled “low sodium” must meet a defined sodium limit.
“Reduced sodium,” on the other hand, is a comparison with the regular version of that particular food. It can still contain a meaningful amount of sodium.
So even when the front of the package sounds reassuring, turn it around.
The Nutrition Facts panel tells you what you are actually getting.
What About Sea Salt and Himalayan Pink Salt?
Sea salt, kosher salt, and Himalayan pink salt may differ in texture, flavor, processing, or trace mineral content.
But they are still salt and still contribute sodium.
Switching from ordinary table salt to a specialty salt does not automatically turn a high-sodium diet into a low-sodium one.
There is also another practical consideration: some specialty salts are not iodized. Iodized salt is an important dietary source of iodine for many people.
Choose salt for flavor and cooking preference—not because one variety is marketed as a nutritional shortcut.
Simple Ways to Cut Back Without Eating Bland Food
Reducing sodium does not require eating flavorless meals.
Start with the changes that are easiest to repeat:
- Compare similar products using %DV.
- Choose unsalted nuts and seeds more often.
- Look for low-sodium or no-salt-added beans and vegetables.
- Rinse canned beans and vegetables when appropriate.
- Use herbs, garlic, citrus, vinegar, pepper, and spices for flavor.
- Keep sauces and dressings on the side.
- Taste food before automatically adding salt.
The FDA specifically recommends rinsing sodium-containing canned foods and choosing low-sodium or no-salt-added nuts, seeds, and vegetables when possible.
Small swaps across several meals are usually more realistic than trying to eliminate salt completely.
Frequently Asked Questions
Is 2,300 mg of sodium the same as 2,300 mg of salt?
No. Sodium is only one component of salt. The 2,300 mg recommendation refers specifically to sodium, not the total weight of salt.
Is sodium always unhealthy?
No. Sodium is an essential nutrient. The concern is routinely consuming more than the body needs, not eliminating sodium altogether.
Is sea salt healthier than regular salt?
Not in a way that eliminates the need to watch sodium. Different salts can vary in texture and trace minerals, but all contribute sodium.
Should everyone follow the same sodium limit?
Not necessarily. People with certain health conditions, medications, or unusually high sweat losses may have different needs. Follow individualized advice from your healthcare professional when applicable.
The Bottom Line
You do not need to fear salt or count every milligram of sodium.
A much easier habit is to look at the % Daily Value.
Remember two numbers: 5% is low and 20% is high.
Compare similar foods, pay attention to serving size, and choose lower-sodium versions when the difference is meaningful.
Because most sodium is already in packaged and prepared foods, those small label-reading decisions can matter more than simply hiding the salt shaker.
