Low to MediumHealth & Lifestyle, Culinary, Informal
Definition
Meaning
A deactivated, processed form of yeast (often Saccharomyces cerevisiae) sold as flakes or powder, used as a food ingredient, especially in vegan cooking for its cheesy, nutty flavour and nutrient content.
A health-food product valued for its high content of protein, B vitamins (including B12 when fortified), and minerals, often used as a condiment, seasoning, or dietary supplement. It is distinct from baker's or brewer's yeast.
Linguistics
Semantic Notes
Always used as a compound noun (adj.+noun). The term denotes a specific product category, not a natural state of yeast. It often carries positive connotations of health, veganism, and natural eating.
Dialectal Variation
British vs American Usage
Differences
No significant lexical differences. The product name is identical. Spelling: 'flavour' (UK) vs. 'flavor' (US) in surrounding descriptions.
Connotations
Slightly more mainstream in US health-food culture; in the UK, it may still be perceived as a more niche, specialist vegan ingredient.
Frequency
Higher frequency in US English due to larger vegan/health-food market penetration.

Watch out
Common Pitfalls
Translation Traps (for Russian speakers)
- Avoid translating as 'пищевые дрожжи' (which typically means baker's/brewer's yeast). The correct equivalent is 'питательные дрожжи' or 'неактивные дрожжи'.
- It is not 'дрожжевая паста' or 'дрожжевой экстракт' (like Marmite).
Common Mistakes
- Using it as a leavening agent in baking (it is deactivated).
- Confusing it with Brewer's yeast, which has a bitter taste.
- Pronouncing 'yeast' as /ji:st/ in American English (it's /jist/).

FAQ
Frequently Asked Questions
No. Nutritional yeast is deactivated (killed with heat) and has a cheesy, nutty flavour. Baker's yeast is alive and used to make bread rise, and it tastes bitter.
No, it does not naturally contain B12. Most commercial nutritional yeast is fortified with synthetic B12, which is essential for vegans.
Probably not. Although processed, it is derived from yeast and may trigger a reaction in those with a Candida or true yeast sensitivity. Consult a doctor.
Store it in a cool, dark place in an airtight container. Refrigeration after opening can extend its shelf life and prevent clumping.
