№ 10 Nutritional Yeast

Nutritional yeast is a deactivated yeast, specifically Saccharomyces cerevisiae, valued for its nutritional profile and savory umami flavor rather than its omega content. This means it’s not a live yeast like the kind used in baking and brewing. This inactive yeast is sold as a supplement in the form of flakes or powder. The name “nooch” has gained popularity as a vegan-friendly superfood due to its impressive nutritional profile. The golden-colored supplement is a complete protein (9/9 essential amino acids), containing all nine essential amino acids that the body cannot produce on its own. What makes nutritional yeast particularly valuable is its exceptional B-vitamin content, especially vitamin B12 which is primarily found in animal products. Fortified nutritional yeast can provide more than 300% of the recommended daily amount of vitamin B12 in just one tablespoon, making it an essential supplement for vegans and vegetarians.

Beyond its protein and vitamin content, nutritional yeast contains beneficial compounds like beta-glucan, a type of fiber that may help lower cholesterol levels and support immune function. It also provides important minerals such as zinc, which aids in immune support and wound healing, and selenium, which acts as an antioxidant. The savory, cheese-like flavor makes it an excellent dairy-free alternative for adding umami taste to various dishes, from pasta to popcorn.

The Omega Reality: Nutritional yeast has a poor 50:1 omega-6 to omega-3 ratio, but this is nutritionally irrelevant because it’s extremely low in total fat (only 1-3g per serving). You’re not using nutritional yeast as a fat source—you’re using it for complete protein, B-vitamins (especially B12), and savory umami flavor. A typical 2-tablespoon serving contains less than 1g of fat, so the omega ratio has virtually no impact on your overall dietary omega balance.

Why Use Nutritional Yeast: Think of it as a B-vitamin powerhouse and flavor enhancer, not a fat source. It’s perfect for adding to popcorn, pasta, salads, and sauces for a cheesy, savory boost while delivering essential nutrients—especially critical B12 for plant-based diets.
