What to know about baking soda
Baking soda is pure sodium bicarbonate, a single inorganic salt, and it grades clean right across the food chemistry triggers: A for gluten, lactose, dairy protein, histamine and histamine liberation, sulfite, nitrite, nickel, glutamate and nightshade. If a muffin set you off, the culprit is almost certainly the flour, the dairy or the fruit, not the leavening. The two things genuinely worth knowing are that it is about a quarter sodium by weight, so a level teaspoon carries roughly 1,200 mg of sodium, and that swallowing it by the spoonful as a heartburn remedy is a documented safety problem rather than a folk cure. It also does nothing on its own: baking soda needs an acid in the batter to release its carbon dioxide, which is the practical difference between it and baking powder.
Watch for
- Sodium load: sodium bicarbonate is roughly 27 percent sodium by weight, so a teaspoon carries about 1,200 mg.Spread across a whole tray of scones that is trivial, but taken neat it is a serious salt dose
- Antacid misuse is the real hazard.Repeated spoonfuls for heartburn have caused metabolic alkalosis and high blood sodium, and there are case reports of gastric rupture when a large dose hit a full stomach and generated gas faster than it could be belched out. This is a dosing risk, not a sensitivity
- It needs an acid to work.Without buttermilk, yogurt, lemon, molasses or cocoa in the mix it does not fully react, and the leftover alkali leaves a soapy, metallic bitterness people sometimes misread as a reaction to the food
- Salicylate, oxalate and overall FODMAP are listed as unrated here.It is an inorganic mineral salt with no plant chemistry, so there is nothing in it for those particular triggers to come from, but the grade sheet does not state a value
- Free of the top allergens by its nature: one ingredient, no wheat, no milk, no soy, no additives to check
