Salt has no calories, fat, carbohydrate or protein

Plain table salt provides 0 calories. It is sodium chloride, not an energy-supplying food. Its lack of calories does not make unlimited use harmless; sodium is the relevant figure to watch. Seasoning mixtures containing sugar or other ingredients need their own labels. [1]

Sodium in one gram, one teaspoon and one tablespoon

The source contains 387.58 milligrams of sodium per gram of salt. Its teaspoon weighs 6 grams, giving 0 calories and 2325.48 milligrams of sodium. A source tablespoon weighs 18 grams and contains 6976.44 milligrams of sodium. Grain size and how the spoon is filled can change those weights.

A source dash is 0.4 grams, but your pinch may differ. Use a suitable scale when a small weight matters. The 100-gram comparison basis is not a serving suggestion. For a ready meal, the total salt in a 200 g Tada stuffed-leaf pack needs to be read alongside the pack size. The salt and sodium calculation for 30 g of Pringles Original shows the distinction on a packaged-food label. Larger amounts still have no calories; that arithmetic says nothing about a safe amount to consume.

A 220 g portion of the pomegranate shepherd salad reference contains about 992 mg sodium, equivalent to 2.48 g salt. The 5 g salt listed for the full recipe does not mean another 5 g was added to that one plate.

Dividing bouillon’s salt between portions likewise requires the dry grams added and the number of equal shares.

Does the daily limit mean salt you can add at the table?

No. WHO recommends adults keep total salt below 5 grams a day, corresponding to less than 2,000 milligrams of sodium. Salt in bread, cheese, sauces and prepared foods counts too. The sodium calculation for dried salted jellyfish is another example of low calories not implying low sodium. WHO's practical conversion is roughly 400 milligrams of sodium per gram of salt; the 387.58 milligrams here comes from the specific USDA entry.

Salt and sodium are not interchangeable label numbers. Seasoning with a herb such as dried oregano is one option, while sodium from the other ingredients still counts. Use a calculation for the portion you actually eat. Not adding table salt does not mean you get no sodium from food; canned hominy is one grain product where the brand label and portion weight both matter. For other examples, the FDA sodium guide explains these less obvious sources. The 18 g spoon calculation for hydrolysed-protein soy sauce shows how even a small condiment serving can contribute to total sodium.

Can salt affect the scale without adding calories?

Yes. Sodium can affect fluid balance, so a short-term rise after a salty meal is not automatically body-fat gain. There is no reliable rule that one gram of salt holds a fixed amount of water in every person. Kidney function, medication and the rest of the diet matter. The FDA explanation of sodium, water and blood pressure concerns fluid regulation, not calories.

Iodized, sea salt or a lower-sodium substitute?

Iodization does not add calories, but this generic entry cannot tell you a product's iodine content. A sea-salt or rock-salt name does not establish lower sodium either. In other kitchen ingredients, such as low-sodium baking powder, check potassium separately: low sodium does not mean low potassium. Read the label. Potassium-based substitutes are different products and may be unsuitable with kidney disease or medicines that affect potassium. See the guidance on individual sodium and potassium needs before treating them as an automatic swap.
