Overview
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.

What trips people up
- 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

FAQ
Common questions about Baking soda
Is baking soda a food trigger?
For the sensitivities this app tracks, no. Baking soda grades A on histamine and histamine liberation, gluten, lactose, dairy protein, sulfites, nitrites, nickel, glutamates and nightshades, and it is a single mineral salt with no additives, flavourings or plant compounds behind it. The amount left in a finished bake is tiny and mostly neutralised by the acid it reacted with. If baked goods reliably bother you, log the flour, the milk or butter, and the dried fruit before you suspect the leavening.
Is it safe to drink baking soda for heartburn?
An occasional small dose is what antacid products are built on, but repeated or heaped spoonfuls are genuinely risky. Bicarbonate taken in quantity can push the blood alkaline, a state called metabolic alkalosis, and it raises blood sodium at the same time. There are published case reports of the stomach rupturing when a large dose was taken on a full stomach and released carbon dioxide faster than it could escape. If you need something regularly for reflux, that is a conversation with a clinician rather than a kitchen fix.
Is baking soda gluten free?
Yes. It is sodium bicarbonate and nothing else, a mined or manufactured mineral salt with no grain anywhere in it, so it is graded A for gluten and is safe for coeliac disease. This is different from baking powder, which contains a starch buffer that is usually cornstarch but is occasionally wheat starch, and therefore needs a label check.
What is the difference between baking soda and baking powder?
Baking soda is one chemical, sodium bicarbonate, and it only produces lift when something acidic in the batter reacts with it. Baking powder is baking soda that has already been packaged with a powdered acid plus a starch buffer to keep the two apart until they get wet, so it works in a batter with no acidic ingredient at all. Baking soda is far stronger by volume, which is why recipes call for a fraction of a teaspoon of soda where they would use several teaspoons of powder.
