It consists wholly of minerals, mainly sodium, but also calcium, manganese, copper, and others.

Calories in Table Salt

As table salt contains no macronutrients, it also provides no calories. Even a 100g serving of table salt contains 0 calories.

Regardless of the calorie content, increased salt intake has been associated with weight gain and obesity (1, 2). This correlation may be due to the fact that people with higher salt intake often present with worse eating habits.

A sudden rise in sodium intake may also lead to temporary weight gain through water retention in the body (3).

However, in many countries, about 80% of salt in the diet comes not from table salt but instead from processed foods (4).

Comparison to Other Seasonings

In the table below, we can see how different table salt’s calorie content is compared to the calories of popular seasonings and spices.

Health checks

Low in Cholesterol
 ⓘ Dietary cholesterol is not associated with an increased risk of coronary heart disease in healthy individuals. However, dietary cholesterol is common in foods that are high in harmful saturated fats.
No Trans Fats
 ⓘ Trans fat consumption increases the risk of cardiovascular disease and mortality by negatively affecting blood lipid levels.
Low in Saturated Fats
 ⓘ Saturated fat intake can raise total cholesterol and LDL (low-density lipoprotein) levels, leading to an increased risk of atherosclerosis. Dietary guidelines recommend limiting saturated fats to under 10% of calories a day.
Low in Sodium
limit break
 ⓘ Increased sodium consumption leads to elevated blood pressure.
Low in Sugars
 ⓘ While the consumption of moderate amounts of added sugars is not detrimental to health, an excessive intake can increase the risk of obesity, and therefore, diabetes.
