Why it's used
Manufacturers add nutritional yeast for its savoury flavour profile, often used as a cheese substitute in vegan and vegetarian dishes. It can also contribute a 'meaty' or umami taste to savoury products like seasonings, sauces, and meat alternatives. Its mild flavour makes it versatile in various food types, including cheese substitutes, protein powders, and vegetarian ready meals.
Health notes
Nutritional yeast is not considered a food additive in the UK and does not have an E-number. It is a source of B vitamins, and some commercial products are fortified with vitamin B12. The European Food Safety Authority (EFSA) has evaluated *Saccharomyces cerevisiae* in the context of its use as a feed additive, but it is not subject to the same regulatory framework as food additives in the UK. There are no widespread controversies regarding its consumption at typical dietary levels.
