For adults, anything above 2,300 milligrams of sodium per day is considered too much. That’s roughly one teaspoon of table salt. The World Health Organization sets the bar even lower at 2,000 mg. Yet the average American consumes over 3,300 mg daily, which means most people are regularly eating what qualifies as “a lot” of sodium without realizing it.
The Daily Limits That Define “Too Much”
The number you’ll see most often is 2,300 mg per day, which is the cap set by the Dietary Guidelines for Americans for anyone age 14 and older. For context, that 2,300 mg is the sodium in about one teaspoon of table salt. If you’re working to lower your blood pressure, the National Heart, Lung, and Blood Institute recommends going further, down to 1,500 mg per day, a level shown to produce additional drops in blood pressure beyond what the standard limit achieves.
Children under 14 should stay even lower than 2,300 mg, with limits varying by age. And globally, the WHO has been pushing member nations toward a target of under 2,000 mg per day, with a goal of reducing average population intake by 30% by 2025.
The gap between what’s recommended and what people actually eat is striking. At 3,300+ mg per day on average, most Americans exceed the recommended ceiling by roughly 50%. That’s not because people are heavy-handed with the salt shaker. Most excess sodium comes from packaged and restaurant foods, not salt added at the table.
What High Sodium Looks Like in a Single Meal
A useful way to think about “a lot” is at the meal level. If the daily cap is 2,300 mg, a single meal probably shouldn’t exceed 600 to 800 mg. But fast-food and sit-down restaurant meals regularly blow past that. Research tracking sodium in fast-food menus found that a typical combo meal (entrée, side, and condiment) averaged nearly 2,000 mg of sodium. That’s almost an entire day’s worth in one sitting. Individual menu items at major chains have been documented as high as 3,150 mg, and during some periods, the highest single items reached over 4,600 mg.
Frozen dinners, canned soups, deli meats, and sauces are common culprits in grocery stores. A single cup of canned soup can contain 800 to 1,000 mg. Two slices of deli turkey might add 400 to 500 mg. These numbers add up fast, especially when you’re eating multiple processed foods in a day.
How to Read Sodium on a Label
When you’re scanning nutrition labels, the Daily Value percentage is the quickest shortcut. Labels are based on the 2,300 mg daily limit. A food with 5% DV or less per serving is low in sodium. A food with 20% DV or more per serving (that’s 460 mg or above) is high. Anything in between is moderate.
You’ll also see marketing terms on packaging. “Sodium free” means less than 5 mg per serving. “Very low sodium” means 35 mg or less. “Low sodium” means 140 mg or less. “Reduced sodium” only means the product has 25% less sodium than the original version, which can still be a lot if the original was loaded. Always check the actual milligrams rather than trusting front-of-package claims.
One conversion worth knowing: sodium and salt aren’t the same measurement. One gram of sodium equals about 2.5 grams of salt. So when a label says 920 mg of sodium, that’s equivalent to about 2.3 grams of salt.
Why Excess Sodium Raises Blood Pressure
When you eat more sodium than your body needs, your kidneys hold onto extra water to dilute it. That increases the total volume of fluid in your bloodstream. More fluid means more pressure against your artery walls, which is, in simple terms, high blood pressure. Over time, that extra pressure damages blood vessels, strains the heart, and increases the risk of heart attack and stroke.
This effect is more pronounced in some people than others. Body weight plays a role: research has shown that people with a higher BMI tend to retain more fluid during periods of high salt intake, suggesting that sodium and weight compound each other’s effects on blood pressure. The combination of excess sodium and excess weight may be especially harmful even in younger adults.
Salt Sensitivity Varies From Person to Person
Not everyone’s blood pressure responds to sodium the same way. Roughly 40% of people with high blood pressure and about 20% of people with normal blood pressure are “salt-sensitive,” meaning their blood pressure rises more sharply in response to sodium and drops more noticeably when they cut back. If you’ve noticed that a salty meal leaves you puffy, bloated, or with a headache, you may be on the more sensitive end of the spectrum.
There’s no widely available consumer test for salt sensitivity, so the practical advice is the same for most people: keep sodium under 2,300 mg, and aim for closer to 1,500 mg if you have high blood pressure, kidney disease, or diabetes. People who are salt-sensitive simply stand to benefit even more from staying at the lower end.
Practical Ways to Cut Back
The most effective single change is cooking more meals at home with whole ingredients. When you control what goes into the pot, you control the sodium. Fresh vegetables, plain grains, unseasoned meats, and legumes are all naturally very low in sodium. The salt you add while cooking is typically far less than what a manufacturer or restaurant adds for you.
When buying packaged foods, compare brands. Sodium content can vary wildly between two nearly identical products. One brand of pasta sauce might have 300 mg per serving while another has 600 mg. Rinsing canned beans and vegetables under water removes a meaningful portion of the added sodium. Choosing fresh or frozen vegetables over canned versions eliminates the problem entirely.
At restaurants, asking for sauces and dressings on the side gives you control over the biggest sodium contributors in most dishes. Soups, anything described as “crispy” (usually breaded and seasoned), and combination dishes like stir-fries and pasta tend to be the highest-sodium options on a menu. Grilled proteins and simple sides are generally safer bets.
Your taste buds adjust. People who reduce sodium intake consistently report that after two to three weeks, food at their previous salt level starts tasting too salty. The adjustment period is real but temporary, and most people find they start noticing other flavors in food that the salt was masking.
