Sodium carbonates (baking soda)

Group: Acidity regulators · in the book

Harm level1 of 5No concern

In plain words

These are sodium carbonates, including the familiar baking soda, which releases carbon dioxide and makes dough rise. You meet them in baking powder, biscuits, gingerbread and effervescent tablets.

Where you find it: baking powder, biscuits, baked goods

Our recommendation

No need to avoid it; on a sodium-restricted diet keep its sodium in mind.

Possible risks and effects

  • No relevant risk known at normal intake.
  • Adds to sodium intake – relevant on a low-salt diet.

For experts

The group covers sodium carbonate, sodium hydrogen carbonate and sodium sesquicarbonate, used as raising agents and acidity regulators. They are simple inorganic salts handled by the body as ordinary sodium and bicarbonate ions; in the EU they are authorised at quantum satis.
