how much – Most Americans consume about 3,400 milligrams of sodium per day—well above recommended limits—driven largely by processed, packaged, and restaurant foods. Dietitians stress that sodium is essential, but the margin between “enough” and “too much” is where heart
When the soup comes out too salty, it’s tempting to blame the cook. But in the United States, the bigger problem isn’t just occasional oversalting—it’s a daily pattern. On average. people in the country consume roughly 3. 400 milligrams of sodium per day. a level far above recommended limits and higher than many global averages. largely because of processed and packaged or restaurant foods rather than the saltshaker.
That gap matters because excess sodium has been tied to serious health outcomes. Too much salt is linked to high blood pressure, stroke, and heart disease—concerns that turn a kitchen habit into a public health issue.
What complicates the picture is that the story isn’t “salt is bad.” Sodium is an essential nutrient your body needs to function properly. The real issue is balance.
Salt isn’t automatically the enemy—sodium is needed
“Sodium chloride” plays a fundamental role in keeping the body running smoothly. and it is essential for normal functioning. according to Monica Kelly. a registered dietitian at Montefiore Health System in New York. Sodium is also one of the body’s key electrolytes. a group of minerals that help regulate fluid balance and other important functions.
Lisa Young, a registered dietitian nutritionist, author of “Finally Full, Finally Slim” and an adjunct professor of nutrition at New York University, says sodium supports nerve signaling and is important for proper muscle contraction.
In rare cases, very low sodium intake or excessive fluid loss can cause hyponatremia, a condition in which sodium levels in the blood become dangerously diluted. Young explains that symptoms can include headaches, confusion, nausea—and in severe cases, seizures.
For most people eating a typical diet, sodium deficiency is very rare. It also isn’t inherently harmful because the body needs sodium in far smaller amounts than most people consume.
What happens when sodium tips too far
Consistently eating too much sodium can strain nearly every major system in the body. The most well-known impact is blood pressure.
Kelly describes the mechanism this way: high sodium intake causes the body to hold onto water, which increases blood volume and makes the heart work harder. Over time, that added pressure can stiffen blood vessels and raise the risk of hypertension, a major contributor to heart disease and stroke.
Excess salt intake has also been linked in studies to other health concerns. Research suggests a connection between high salt intake and reduced bone density. since excess sodium can increase calcium loss through urine. Some research has also associated high-sodium diets with a greater risk of stomach cancer. possibly due to damage of the stomach lining.
Young adds that too much sodium can cause kidney disease by straining the kidneys. emphasizing that the kidneys play a key role in regulating fluid balance and filtering waste from the body. She also notes that. though less serious. eating too much salt can leave people feeling bloated. thirsty. and sluggish due to fluid retention and dehydration imbalances.
A daily number to aim for—hard for many to hit
So how much sodium should people actually eat? The American Heart Association recommends that most adults consume no more than 2,300 milligrams of sodium per day—roughly equivalent to 1 teaspoon of salt—with an ideal target of no more than 1,500 milligrams daily for most people, Young says.
Young adds that this lower target is especially important for those with high blood pressure or those at risk for heart disease.
The challenge is that the majority of sodium in the American diet doesn’t come from the saltshaker. It comes from packaged, processed, and restaurant foods.
That’s why Kelly advises people to read food labels carefully and choose items with 140 mg of sodium or less per serving. She says this is the threshold considered “low sodium.” Another step she points to is rinsing canned foods such as beans or vegetables before eating them.
Practical steps that don’t require giving up flavor
Keeping intake in a healthier range can come down to a few concrete habits. Kelly recommends cooking more meals at home, explaining that it lets people control how food is seasoned. Instead of leaning on salt. she suggests herbs. spices. citrus. and garlic—ingredients that can bring big flavor without adding salt.
Young similarly urges people to choose fresh foods such as fruits, vegetables, beans, whole grains, and lean proteins, saying these options are typically much lower in sodium than other products.
Eating out can still fit, but it requires a different approach. Kelly says opting for grilled, baked, or steamed dishes—and asking for sauces and dressings on the side—can make a meaningful difference.
Strategies like these, Young adds, make it possible to enjoy delicious food while keeping sodium intake in a healthy range.
In a household setting, the line between “seasoned” and “over-salted” often comes down to attention. In the broader U.S. diet, the same question follows a person every day—written into packaged labels, restaurant portions, and the sodium totals that add up long before the saltshaker ever gets used.
