Most major health organizations recommend keeping sodium intake under 2,300mg per day for the general population, with an ideal target closer to 1,500mg for those managing blood pressure concerns. Since most dietary sodium comes from processed and restaurant foods rather than the salt shaker, tracking your intake can help identify hidden sources in your diet. Sodium regulates fluid balance, enables nerve signaling, and supports muscle function — including the heart — which is why it can't simply be eliminated. The bigger issue is that most modern diets, especially those heavy in processed and restaurant food, deliver far more than the roughly 2,300 mg daily upper limit recommended by major health organizations, with most of that excess hidden in packaged food rather than the salt shaker. Because most excess sodium in a typical diet comes from packaged and restaurant food rather than the salt shaker at home, checking nutrition labels on frequently-eaten packaged items usually reveals more actionable opportunities to reduce intake than trying to track every gram of salt added while cooking.
Sodium plays essential physiological roles — regulating fluid balance, enabling nerve signal transmission, and supporting proper muscle function, including the heart muscle — which is why it can't simply be eliminated from the diet without serious health consequences. The issue for most people in modern diets isn't sodium's function but its quantity: health organizations like the World Health Organization recommend under 2,000 mg per day, while actual average intake in many countries runs considerably higher, often 3,000-4,000 mg or more, largely due to sodium hidden in processed and restaurant food rather than the salt shaker at home.
Roughly 70-80% of dietary sodium in a typical Western diet comes from processed and prepared foods — bread, deli meat, canned soup, sauces, and restaurant meals — rather than salt added during home cooking or at the table, which is a genuinely surprising statistic to most people and explains why "I don't add much salt" doesn't reliably predict low sodium intake. This hidden-source pattern is precisely why reading nutrition labels matters more for controlling sodium than adjusting the salt shaker at home.
Excess sodium intake is most strongly linked to elevated blood pressure, since sodium causes the body to retain more fluid, increasing blood volume and the pressure on artery walls — a well-established relationship that makes sodium reduction a standard first-line recommendation for managing hypertension, alongside broader dietary patterns like the DASH diet, which emphasizes fruits, vegetables, and low-fat dairy while limiting sodium.
Individual sodium sensitivity varies — some people's blood pressure responds much more strongly to sodium intake than others, a trait partly genetic and partly related to existing kidney function and overall health — but general population-level guidance to reduce processed food intake and check labels remains sound advice for most people, particularly anyone with existing high blood pressure, kidney disease, or a family history of cardiovascular disease.
Table salt is about 40% sodium by weight — 2,300mg sodium equals roughly 1 teaspoon of salt.
Not the salt shaker — most comes from processed, packaged, and restaurant food, often making up more than three-quarters of total daily sodium without the person realizing it.
Primarily from processed, packaged, and restaurant foods rather than salt added at home.
