Baking Soda's High Sodium Content
Baking soda has long been an essential leavening ingredient for baking, but sometimes its high sodium content can be a problem for those who need to restrict their salt consumption. Finding low-sodium substitutions for baking soda without sacrificing leavening can be trickier than it sounds because an obvious choice, baking soda, contains sodium.
Baking soda's beneficial leavening quality comes at a high cost in sodium. There are 150 milligrams of sodium in 1/8 teaspoon of baking soda. That's almost as much as the human body actually needs in one day, which ranges between 180 and 500 milligrams, according to a study by the CDC.
