E500ii (Sodium Bicarbonate) and Gut Health
E500ii, also known as sodium bicarbonate or baking soda, is a common food additive used as a leavening agent and acidity regulator. It plays a unique role in food processing and may influence gut health in specific ways. Here are the key facts:
- E500ii is not a FODMAP and does not contain fermentable carbohydrates
- Does not contain histamine or act as a histamine liberator
- No fiber content; does not feed gut bacteria
- May temporarily neutralize stomach acid, affecting digestion and reflux
- Rarely causes allergies or intolerances
- Used in baking, antacid products, and as an anti-caking agent
E500ii and FODMAP
Sodium bicarbonate (E500ii) is not a FODMAP. It is a simple inorganic salt and contains no fermentable carbohydrates. This means it does not contribute to gas, bloating, or other FODMAP-related symptoms in people with irritable bowel syndrome (IBS) or sensitive guts. It is generally considered safe from a FODMAP perspective.

Histamine and E500ii
E500ii does not contain histamine, does not trigger histamine release, and does not block DAO (the enzyme that breaks down histamine). It is not considered a concern for people with histamine intolerance or mast cell activation issues. Sodium bicarbonate is chemically neutral in relation to histamine pathways.

Sodium Bicarbonate and Digestion
Sodium bicarbonate is alkaline and can temporarily neutralize stomach acid when consumed. This effect is why it is used in some antacid products for heartburn or acid reflux. However, regular or excessive use may interfere with normal digestion, as stomach acid is needed for protein breakdown and protecting against pathogens.
E500ii and Reflux Symptoms
Because sodium bicarbonate neutralizes acid, it can provide quick relief from reflux or heartburn. However, overuse may reduce stomach acidity too much, potentially leading to digestive discomfort or altered gut flora. Occasional use in food or as an antacid is generally safe for most people.
Fiber Content of E500ii
E500ii contains no dietary fiber, soluble or insoluble. It does not feed beneficial gut bacteria or contribute to bowel regularity. Its role in the gut is purely chemical and does not impact the microbiome through prebiotic effects.
Allergy and Intolerance to E500ii
Allergic reactions to sodium bicarbonate are extremely rare. Most people tolerate it well, even in sensitive populations. In rare cases, excessive intake may cause mild gastrointestinal upset, but true allergies are not reported in the scientific literature.

Common Uses and Preparation
E500ii is widely used in baking to help dough rise, as well as in processed foods as an acidity regulator and anti-caking agent. It is also found in some antacid tablets. Its use in typical food amounts is considered safe for most people with gut sensitivities.
