Understanding the Calorie Count in Nutritional Yeast
Nutritional yeast, affectionately nicknamed "nooch," has become a popular pantry staple, celebrated for its savory, cheese-like flavor and robust nutritional profile. When it comes to managing dietary intake, knowing the calorie content of your favorite foods is crucial. For a standard 20g serving of nutritional yeast, the calorie count typically falls within a narrow range. For example, some brands may list a 20g portion at 67 calories, while others could be slightly lower. This slight variation is normal and can depend on processing and specific brand fortification. The overall takeaway is that nutritional yeast is relatively low in calories, especially when considering its nutritional density. Its low-fat, sugar-free, and gluten-free nature makes it a great addition for many dietary plans.
The Macronutrient Breakdown
Beyond just calories, the macronutrient composition of nutritional yeast reveals its true value as a health food. For a 20g serving, the macros are very favorable, consisting mostly of protein and carbohydrates, with minimal fat. A typical 20g serving provides approximately:
- Protein: Around 8 grams. This makes it an excellent source of complete plant-based protein, which contains all nine essential amino acids.
- Carbohydrates: Approximately 8 grams. Of this, a significant portion is dietary fiber, with about 4 grams per 20g serving.
- Fat: Around 1 gram, or less. Nutritional yeast is naturally low in fat, making it a heart-healthy alternative to high-fat seasonings.
The Vitamin and Mineral Powerhouse
Nutritional yeast is not just about macronutrients; it is also a fantastic source of vitamins and minerals, especially when fortified. Most varieties are fortified with significant levels of B vitamins, a common deficiency in many vegan and vegetarian diets. A 20g serving of fortified nutritional yeast can deliver a substantial percentage of your daily intake for many essential nutrients:
- Vitamin B12: Crucial for nerve health and red blood cell production, fortified nutritional yeast offers a reliable vegan source of this vitamin.
- Riboflavin (B2) & Niacin (B3): Important for energy metabolism and cell function.
- Folate (B9): Vital for DNA synthesis and repair.
- Zinc: An antioxidant with anti-inflammatory properties that also supports immune function.
- Fiber: The beta-glucan fiber in nutritional yeast can help lower cholesterol and support digestive health.
Using Nutritional Yeast in Your Cooking
Thanks to its unique umami, cheesy, and nutty flavor profile, nutritional yeast is incredibly versatile. Here are some popular ways to incorporate it into your meals:
- As a cheese substitute: Sprinkle it over pasta, popcorn, or roasted vegetables for a cheesy taste without the dairy.
- To thicken sauces: Add it to sauces, dips, and gravies for a richer, creamier consistency.
- In vegan recipes: It is a key ingredient in many vegan versions of mac and cheese, creamy soups, and plant-based scrambles.
- On salads and tofu: Dust it over salads or mix into tofu scrambles for added flavor and nutrients.
Nutritional Yeast vs. Parmesan Cheese: A Comparison
For many, nutritional yeast serves as a direct alternative to Parmesan cheese. The following table highlights the key nutritional differences, using a standard 20g serving for nutritional yeast and a comparable portion for Parmesan.
| Feature | Nutritional Yeast (20g) | Parmesan Cheese (20g) | Difference & Benefit of Nooch |
|---|---|---|---|
| Calories | ~60-70 kcal | ~80-90 kcal | Lower calorie count. |
| Protein | ~8g | ~7g | Slightly higher protein content per gram. |
| Fat | ~1g or less | ~6g | Significantly lower fat, no saturated fat. |
| Saturated Fat | 0g | ~4g | Heart-healthy option. |
| Sodium | Low, approx. 20-30mg | Higher, approx. 300mg+ | Much lower sodium content, better for blood pressure. |
| Vitamin B12 | Often fortified with high levels | Not a significant source | Crucial for vegan diets. |
| Dietary Fiber | ~4g | 0g | Supports digestion and satiety. |
Potential Considerations
While generally very healthy, it's worth noting a few potential considerations for certain individuals. Nutritional yeast contains tyramine, an amino acid that can trigger headaches in some people with migraines. Additionally, for those with inflammatory bowel conditions like Crohn's disease, consuming large amounts could exacerbate symptoms due to the high fiber content. As with any dietary change, moderation and monitoring your body's response is key. It's always a good idea to consult a doctor before making significant changes to your diet, especially if you have existing health conditions.
Conclusion
In summary, 20g of nutritional yeast offers a modest calorie count of approximately 60 to 70 calories, delivering a powerful punch of protein, fiber, and B vitamins in return. Its low-fat, low-sodium, and sugar-free profile makes it a stellar nutritional choice for adding a savory, cheese-like flavor to a wide variety of dishes. Whether you are vegan, vegetarian, or simply looking to boost the nutrient content of your meals, a sprinkle of nooch is a healthy, delicious, and easy-to-use option.

Practical Uses for a Healthier Diet
To make the most of nutritional yeast, integrate it strategically into your diet. For a quick snack, toss a couple of tablespoons with freshly popped popcorn for a cheesy flavor. For a meal, stir it into creamy soups or sauces at the end of cooking to maintain its potent vitamin content, as heating can degrade some B vitamins. Its thickening properties also work well in plant-based gravies and dressings. Starting with smaller amounts and increasing as you get used to the flavor and texture can prevent digestive issues from the sudden fiber increase. Overall, its versatility and nutritional benefits make it an excellent choice for enhancing both flavor and health in your culinary creations.
