Sodium
How much sodium per day, and why restaurant meals matter
Sodium is the number people notice last and restaurants supply most of. One order can carry a whole day of it.
The limits
| Guidance | Daily limit |
|---|---|
| US Dietary Guidelines, adults | Below 2,300 mg |
| World Health Organization | Below 2,000 mg |
| Physiological requirement | Far lower — a few hundred mg |
The gap between the requirement and the limit is deliberate: the limits are set where population blood-pressure risk begins to rise, not at the minimum needed to live.[1] For scale, 2,300 mg of sodium is about one level teaspoon of table salt.
Where it actually comes from
Most sodium is not added at the table. The large majority of intake in countries with a Western diet arrives already in packaged and restaurant food, which is why a salt shaker is a small lever and a menu is a large one.
- Bread and rolls contribute steadily rather than dramatically — modest per slice, frequent across a day.
- Cured and processed meats are dense sources.
- Sauces, dressings and cheese add up quietly on an otherwise reasonable plate.
- Soups and prepared sides are often higher than they taste.
Something does not have to taste salty to be high in sodium. Sweetness masks it, which is why bread and some sauces surprise people.
What one restaurant meal actually carries
Across the 74 tracked orders that publish a sodium value, the median is 840 mg — roughly 37 per cent of a day in a single sitting. 11 of them carry at least 1,500 mg, and 3 reach or exceed the whole 2,300 mg limit on their own.
That is the practical problem in one line: the limit is a day and the meal is an hour. It is not that any single order is unusually bad, it is that a normal-looking lunch can spend most of the budget before dinner exists.
The heaviest orders in our data
| Order | Chain | Sodium | Share of 2,300 mg |
|---|---|---|---|
| Bigger Plate: chow mein + grilled teriyaki + orange chicken + string bean chicken | Panda Express | 2,880 mg | 125% |
| Footlong Meatball Marinara | Subway | 2,740 mg | 119% |
| Bigger Plate: fried rice + 3 grilled teriyaki chicken entrées | Panda Express | 2,410 mg | 105% |
| Sofritas Bowl with brown rice and black beans | Chipotle | 1,990 mg | 87% |
| High-protein bulking order: Grilled Club, waffle fries and 12-count grilled nuggets | Chick-fil-A | 1,955 mg | 85% |
| High-protein bulking order: 30-count grilled nuggets, waffle fries and large fruit cup | Chick-fil-A | 1,950 mg | 85% |
Two patterns explain almost every entry above. Combination platters multiply the sauce, and cured or brined proteins bring their own. Neither is obvious from the calorie count — the highest-sodium order in the table is not the highest-calorie one.
Lower-sodium orders that are still real meals
The useful comparison is not against a salad. It is against another order with the same protein that happens to cost far less sodium. Every item below carries at least 20 g of protein.
| Order | Chain | Sodium | Share of 2,300 mg |
|---|---|---|---|
| Grilled Nuggets, 8 count | Chick-fil-A | 440 mg | 19% |
| Eggs & Cheddar Protein Box | Starbucks | 450 mg | 20% |
| Grilled Teriyaki Chicken | Panda Express | 470 mg | 20% |
| Broccoli Beef with white steamed rice | Panda Express | 520 mg | 23% |
| 3 Blackened Tenders | Popeyes | 550 mg | 24% |
| Grilled Chicken Salad | Subway | 610 mg | 27% |
The gap between the two tables is the whole argument for looking the number up. Same restaurants, same meal slot, several times the sodium.
This is why every meal in our data shows sodium beside calories and protein instead of hiding it, and why the finder can rank for lower sodium directly.
Who needs to pay closer attention
The population limit is a single line drawn across people whose responses differ. A few groups sit further from the average than the rest:
- Anyone with raised blood pressure. This is the group the limits were set for, and the group where reducing intake changes the number most reliably.
- People eating most meals out. Not a medical category, but a practical one: if the kitchen is someone else’s, you are working from the menu rather than the recipe.
- Endurance athletes in the heat. Sustained heavy sweating loses sodium in amounts that general guidance is not written for. Restricting hard while training hard is the wrong combination.
- Anyone given a specific figure by a clinician. That number outranks anything on this page.
For everyone else the honest summary is unglamorous: most people are somewhat over, the cost of being over is gradual rather than acute, and the fix is a handful of ordering habits rather than a diet.
Keeping the total sensible
- Budget by day, not by meal. A high-sodium lunch is fine if dinner is cooked at home.
- Sauce on the side removes a large share without changing the meal.
- Watch the combination, not the entrée. Sides and drinks are where a reasonable order becomes a high one.
- Potassium matters too. Vegetables, beans and fruit support the same blood-pressure outcome from the other direction.
If you have been told to restrict sodium for a medical reason, follow the figure your clinician gave you rather than a general population limit.

Frequently asked questions
Is 2,300 mg of sodium a target or a limit?
A limit, not a goal. There is no benefit in reaching it, and most guidance treats lower as better for blood pressure across a population.
Does drinking water cancel out a salty meal?
It helps with how you feel and with short-term water retention, but it does not change the sodium you consumed or its blood-pressure effect.
Why does bread contain so much sodium?
Salt controls fermentation and structure in baking, and bread is eaten often enough that a modest amount per slice becomes one of the larger contributors across a day.
