Baking soda is harmless to the body, please rest assured! It's just that it tastes bad when put too much. Isn't there another drink called soda water? Many people like it, and its main ingredient is baking soda. If baking soda is put too much when making cakes or steamed bread, you can add a little edible vinegar to neutralize it. Because baking soda is alkaline, adding vinegar will play a role in acid-base neutralization, so the cakes made will not be bitter.
