Low-sodium baking powder: check the potassium too

Calories per teaspoon and per recipe

The USDA low-sodium baking-powder record gives 97 kcal per 100 g. Its reference teaspoon weighs 5 g: 5 kcal per 5 g, or 2 kcal for half a reference teaspoon, 2.5 g. These are dry ingredient weights, not weights of the finished cake or bread. [1]

Adding 10 g contributes 10 kcal to the whole recipe. Divide that contribution between the equal servings you make. Not every sachet weighs 10 g, and a household spoon need not hold exactly 5 g. Weigh the powder when precision matters; the 100 g comparison column is not a serving recommendation.

Does low sodium make it suitable for a kidney diet?

Not automatically. In this reference, 5 g contains 4.5 mg sodium but 505 mg potassium. Two reference teaspoons, 10 g, contain 9 mg sodium and 1010 mg potassium. Low sodium does not mean low potassium.

If you have kidney disease, high blood potassium or take medicine affecting potassium, discuss the specific label with your care team before switching. Potassium-containing sodium alternatives are unsuitable for some people. The figures here do not establish an individual diet prescription. [2]

Is it the same as baking soda?

No. Baking soda is generally sodium bicarbonate; baking powder is a blend of leavening ingredients. Low-sodium blends vary by manufacturer. Do not calculate ordinary baking soda with this record's low sodium value, or exchange the two one-for-one without considering the recipe.

For coeliac disease, check the starch carrier and gluten statement on your own product. Drinking baking powder, treating reflux or using it for sports performance is outside this kitchen calculation.

Which product does the table describe?

The basis is historical USDA record 18371, not a laboratory analysis of every current low-sodium brand. A 5 g amount has 2.35 g carbohydrate; the source reports zero sugars. Use your product's table if its sodium or potassium differs. These values help count an ingredient in dough, not choose a mineral supplement.
