Daily sodium intake and how to choose a target

The FDA Daily Value for sodium is less than 2,300 mg per day. The American Heart Association recommends no more than 2,300 mg and an ideal limit of 1,500 mg for most adults, while personal targets can differ with health history and clinical advice.

FDA vs. AHA: the two daily sodium intake numbers

Two different numbers show up whenever sodium comes up, and they don't match — which is confusing if you assume there's one official target.

The FDA sets the Daily Value (DV) that appears on every Nutrition Facts label: 2,300mg. That's the figure the %DV column is calculated against, and it's the number most general nutrition guidance treats as the ceiling for a healthy adult.

The AHA goes further. It recommends an ideal limit of no more than 1,500mg a day for most adults, and calls that out specifically for people managing blood pressure. The AHA isn't contradicting the FDA — it treats 2,300mg as the outer boundary and 1,500mg as the better target if you can work down to it gradually.

Source	Recommended daily sodium	Who it applies to
FDA Daily Value	2,300 mg	General reference used on nutrition labels
AHA ideal limit	1,500 mg	Most adults, especially those managing blood pressure
Average U.S. adult intake	~3,400 mg	What people actually eat, per federal dietary survey estimates

The FDA number is a labeling reference for the general population, while the AHA describes 1,500 mg as an ideal limit for most adults. Neither replaces individualized advice, especially when kidney, heart, liver, endocrine, or fluid-balance conditions affect sodium needs.

Why sodium intake adds up before you touch the salt shaker

Here's the part that trips people up: most sodium in the U.S. diet comes from packaged, prepared, and restaurant food. Much of it is already in the food before it reaches your kitchen.

Bread and rolls are a leading source — not because any one slice is loaded with sodium, but because bread shows up in so many meals that the totals stack up fast. Cold cuts and cured meats run high by design; two slices of deli turkey can carry 400-600mg. Cheese, canned soup, bottled sauces, and frozen entrées all lean on sodium as a preservative and flavor carrier, often at levels that surprise people who assume they're eating "clean" because nothing looks salty.

Restaurant food compounds the problem. A single fast-casual meal — a sandwich, a side, a sauce — may approach or exceed 2,300 mg before you've added a grain of salt yourself. None of this requires a heavy hand with the shaker. It requires understanding that sodium is baked into the food supply, largely as a function of how packaged and prepared food is made shelf-stable and flavorful.

This is why cutting back on "salty-tasting" food isn't a reliable strategy. Some genuinely high-sodium foods — bread, cereal, cottage cheese — don't taste salty at all, while some foods that taste intensely salty, like a pickle or a handful of chips, are actually a smaller share of your daily total than a bland-tasting bowl of canned soup. The only way to know what you're actually eating is to look at the numbers, not the taste.

Cooking from scratch helps for exactly this reason — it moves the sodium decision back into your hands. A homemade soup made with fresh vegetables and a light hand with the salt can carry a few hundred milligrams per serving, compared to 700-900mg or more in a canned equivalent. That's not a rule to follow rigidly, but it explains why people who track their intake for a week or two often end up cooking more at home without ever deciding to "eat healthier" in the abstract — the numbers make the trade-off obvious.

How to set your own daily sodium target

For most healthy adults without a specific medical restriction, 2,300mg is a sensible starting target — it matches the FDA's Daily Value, so every nutrition label is already doing part of the math for you. If you're comfortable there and want a tighter goal, stepping down toward the AHA's 1,500mg over a few weeks is a reasonable next move, since a sudden, sharp cut can make food taste flat and hard to stick with.

Some people need a different number for medical reasons. If you have kidney disease, heart failure, or you're on medication that affects sodium or fluid balance, your target may need to be set by a doctor rather than a general guideline, and it's worth asking at your next appointment rather than guessing. The same goes if you're already on a low-sodium diet and unsure whether 1,500mg or something lower is appropriate for your situation.

Age, activity level, and sweat rate can shift the picture too, but for the overwhelming majority of adults, "start at 2,300mg, work toward 1,500mg if you can" covers the guidance from both major U.S. sources without needing anything more specific.

The WHO takes a similar approach on the global stage, recommending less than 2,000mg a day — lower than either U.S. figure. You'll see all three numbers cited depending on the source, which is less a contradiction than a reminder that "daily sodium intake" guidance sits on a spectrum from "don't exceed this" to "this is the more protective target," rather than one fixed rule everyone is expected to hit exactly.

Why tracking against a target beats tracking nothing

A daily sodium number is only useful if you know where you stand against it in real time. "Eat less sodium" is vague enough to ignore; "you've had 1,850mg by 2pm and your limit is 2,300mg" is a decision you can actually act on before dinner.

The problem is that sodium is nearly impossible to estimate by memory. It doesn't correlate with how salty something tastes, and it hides in foods most people don't think to question — bread, sauce, broth, cereal. Without a running total, most people find out they've blown past their target only after the fact, if they find out at all.

This is the gap a food log closes that willpower alone can't. Sodium Tracker is an iPhone app that logs food against a daily sodium limit set from FDA, AHA, and WHO guidance, with fast logging by barcode, photo, or voice, and a library of high-sodium foods — so instead of guessing at dinner, you can see exactly what's left in your budget.

Whatever target you land on — 2,300mg, 1,500mg, or a number set by your doctor — the target only does its job if you're checking your actual intake against it, meal by meal, rather than at the end of the week when the pattern's already set.

FAQ

How much sodium should I eat per day?

The FDA's Daily Value is 2,300mg a day, which is the standard reference for a healthy adult and the number used to calculate %DV on nutrition labels. The AHA recommends an ideal limit of 1,500mg for most adults, especially those managing blood pressure. If you have a medical condition affecting sodium tolerance, ask your doctor for a specific number rather than defaulting to either guideline.

Is 2,300mg of sodium a lot?

It's the upper limit the FDA considers appropriate for a healthy adult, not a target to hit every day. In practice it's easy to exceed — a single restaurant meal or a can of soup plus a sandwich can approach or exceed it before you've eaten anything else that day.

What's the difference between the FDA and AHA sodium guidelines?

The FDA's 2,300mg is the Daily Value used on nutrition labels and represents a general ceiling. The AHA's 1,500mg is a more conservative ideal limit recommended for most adults, particularly those managing blood pressure. Both are guidance figures, not personalized medical advice.

Where does most dietary sodium actually come from?

Roughly three-quarters of sodium in a typical American diet comes from processed and restaurant food — bread, cold cuts, cheese, canned soup, sauces, and prepared meals — rather than salt added during cooking or at the table. That's why cutting back on visible salt use often has less impact than people expect.

Do I need a lower sodium limit if I have high blood pressure or kidney disease?

Possibly — these are exactly the conditions where a general guideline like 2,300mg or 1,500mg may not fit your situation. Talk to your doctor about a specific target rather than assuming either the FDA or AHA number applies to you.
