What is the yeast that vegans eat?

5 min read

Over 79 million people worldwide are vegan, and many of them rely on a special type of inactive yeast to add a cheesy flavor and nutritional boost to their meals. This versatile ingredient, known as nutritional yeast or 'nooch', is a staple in plant-based cooking for its unique taste and impressive nutrient profile.

Quick Summary

This article explores what nutritional yeast is, how it is made, its nutritional benefits, how to use it in vegan cooking, and how it differs from other types of yeast. Discover why this cheesy, nutty seasoning is a vital ingredient for many following a plant-based diet.

Key Points

  • Nutritional Yeast is a Deactivated Fungus: Also known as 'nooch', it's a form of Saccharomyces cerevisiae that has been heat-treated so it can't ferment, distinguishing it from baker's or brewer's yeast.

  • Rich Source of Vitamin B12: Fortified nutritional yeast is a vital dietary source of vitamin B12 for vegans, a nutrient crucial for nerve and blood cell health.

  • Cheesy Flavor Profile: Its distinct savory, cheesy, and nutty taste makes it a popular vegan cheese substitute for dishes like mac and cheese or popcorn.

  • Contains Complete Protein: Nutritional yeast is one of the few plant-based sources that offers a complete protein, containing all nine essential amino acids.

  • Use as a Versatile Seasoning: It can be sprinkled over pasta, vegetables, and salads or used to thicken soups and sauces for added flavor and nutrients.

  • Provides Fiber and Antioxidants: The yeast contains beneficial beta-glucan fiber for immune and heart health, as well as antioxidants to fight cellular damage.

  • Check for Fortification: It is important for vegans seeking B12 to ensure the product label specifies it is 'fortified', as not all versions contain added vitamins.

  • Store Properly: For the longest shelf life, nutritional yeast should be stored in an airtight container in a cool, dark place, where it can last up to two years.

What is Nutritional Yeast?

Nutritional yeast is a deactivated yeast from the species Saccharomyces cerevisiae, the same yeast used in baking and brewing. However, unlike its active relatives, nutritional yeast has been heat-treated during manufacturing, killing the yeast cells. This deactivation process is crucial, as it means nutritional yeast cannot be used to leaven bread or ferment alcohol. Grown on a sugar-rich medium like molasses for several days, the yeast is then harvested, washed, and dried into the characteristic yellow flakes or powder you find in stores.

Nutritional Benefits for Vegans

Nutritional yeast earns its name from its impressive nutritional content, making it a valuable addition to a vegan diet. While unfortified versions naturally contain some vitamins and minerals, most products on the market are fortified, meaning extra nutrients are added during processing.

Key Nutrients

  • Vitamin B12: This is arguably the most critical nutrient provided by fortified nutritional yeast for vegans, as B12 is primarily found in animal products. A single serving can provide a significant portion of the recommended daily intake, helping to prevent fatigue and nerve damage.
  • Complete Protein: Nutritional yeast is a rare plant-based source of complete protein, containing all nine essential amino acids needed for muscle repair and maintenance.
  • Fiber: It contains dietary fiber, including beta-glucan, which can help lower cholesterol and support immune health.
  • Antioxidants: Nutritional yeast contains potent antioxidants like glutathione and selenomethionine, which help protect the body's cells from damage.

How to Use Nutritional Yeast in Vegan Cooking

Nutritional yeast is incredibly versatile in the kitchen, prized for its savory, cheesy, and nutty flavor profile.

Recipes and Applications

  • Vegan Cheese Sauce: It is the key ingredient in many dairy-free cheese sauces for mac and cheese, gratins, and nachos.
  • Popcorn Topping: For a cheesy, savory snack, sprinkle nutritional yeast over freshly popped popcorn instead of butter or salt.
  • Vegan Parmesan: Combine nutritional yeast with cashews, garlic powder, and salt in a food processor to create a convincing vegan Parmesan for pasta or salad.
  • Soups and Sauces: Stir it into creamy soups, gravies, and stews to add depth and a rich, umami flavor.
  • Scrambled Tofu: Add it to your tofu scramble to give it a savory, cheesy kick reminiscent of scrambled eggs.
  • Roasted Vegetables: Toss roasted vegetables like broccoli or brussels sprouts in nutritional yeast for an extra savory layer of flavor.

Important Considerations

While generally safe for most people, there are a few considerations when consuming nutritional yeast. Some individuals with inflammatory bowel diseases, yeast allergies, or migraines may need to avoid it. Additionally, those taking certain medications, such as MAOIs, should consult a doctor due to the presence of tyramine. The high vitamin levels in fortified nutritional yeast make it important to monitor intake, especially if also taking multivitamins. As with any dietary change, moderation is key.

Finding and Storing Nutritional Yeast

Nutritional yeast is widely available at health food stores and major supermarkets, often in the spice or bulk sections. It comes in flakes, granules, or powder form. Store it in an airtight container in a cool, dark, dry place, where it can last for up to two years. For the best nutritional benefits, always check the product label to ensure you are purchasing a fortified version.

Conclusion

For those on a plant-based diet, nutritional yeast is far more than just a seasoning; it's a culinary and nutritional powerhouse. Its ability to replicate a cheesy, savory flavor while providing essential nutrients like vitamin B12 makes it an invaluable staple. From sprinkling it on popcorn to creating creamy vegan sauces, 'nooch' offers a simple and delicious way to enhance flavor and boost nutritional intake, proving that vegan food can be just as satisfying and rich in flavor as any other.

Keypoints

  • Nutritional Yeast is Inactive: Unlike baking yeast, nutritional yeast is heat-treated and deactivated, meaning it cannot leaven bread.

  • Cheesy and Nutty Flavor: Its unique flavor profile makes it an excellent dairy-free substitute for cheese in many recipes.
  • Versatile Kitchen Staple: It can be used as a topping for popcorn, an ingredient in sauces, or a component of vegan Parmesan.
  • Rich in Nutrients: In addition to B12, nutritional yeast is a good source of complete protein, fiber, and antioxidants.
  • Different from Brewer's Yeast: While both are inactive, brewer's yeast is a bitter byproduct of beer brewing, whereas nutritional yeast is grown specifically for consumption and has a cheesy taste.
  • Side Effects are Rare: Most people can safely consume nutritional yeast, but those with yeast allergies, IBS, or on certain medications should exercise caution.
  • Check for Fortification: Not all brands are fortified with B12, so it is important to read the label to ensure you get the desired nutrients.
