Understanding the Calorie Count in Nutritional Yeast
Nutritional yeast, affectionately known as 'nooch', is a deactivated yeast product with a distinct nutty, cheesy flavor. Its popularity has surged, especially within vegan and vegetarian communities, as a flavor-enhancing ingredient and a nutritional supplement. When considering its place in a balanced diet, understanding its caloric content is crucial.
Why the Calorie Count Varies
While the search results show a range of 30 to 40 calories for a 10g serving, this variation is due to several factors, primarily the specific brand and whether the product is fortified. Different manufacturers may use different growing mediums, and the final drying process can impact the macronutrient composition. Some brands are also more heavily fortified with vitamins, which can slightly affect the overall weight and calorie density. It is always recommended to check the specific nutrition facts on the product label for the most accurate information.
Macronutrient Breakdown for 10g
In addition to its low calorie count, 10 grams of nutritional yeast offers an impressive nutritional profile. The macronutrient breakdown for a typical 10g serving reveals why it is a favored dietary supplement:
- Protein: Approximately 4 to 5 grams, making it a valuable source of complete protein for plant-based diets.
- Carbohydrates: Roughly 3 to 4 grams, with some variations depending on fiber content.
- Fat: Generally very low, often less than 1 gram per 10g serving.
The Health and Nutritional Benefits Beyond Calories
Nutritional yeast's benefits extend far beyond its low-calorie, cheese-like flavor. It is a dense source of several vital nutrients that contribute to overall well-being.
Key Nutrients in a Small Serving
- B Vitamins: Many nutritional yeast products are fortified with B vitamins, including B1 (Thiamin), B2 (Riboflavin), B3 (Niacin), B6, and most importantly, B12. Fortified nutritional yeast can be a critical source of B12 for vegans, as this vitamin is not naturally found in plant foods.
- Complete Protein: As mentioned, it contains all nine essential amino acids, which are the building blocks of protein that the body cannot produce on its own. This is a significant advantage for those on plant-based diets.
- Dietary Fiber: The fiber content in nutritional yeast aids in digestive health. It contains beta-glucan, a type of soluble fiber also found in oats and barley, which has been linked to heart health benefits.
- Trace Minerals: Depending on the fortification, it can also provide trace minerals such as zinc, which supports immune function, and iron, crucial for red blood cell production.
Comparison Table: Nutritional Yeast vs. Dairy Cheese
To illustrate its value as a lower-calorie alternative to dairy cheese, consider this comparison based on a similar serving size.

| Fat | <1g | ~2.5g | ~3.3g |
| B Vitamins | High (often fortified) | Very Low | Very Low |
| Sodium | Low | High | High |
| Dairy-Free | Yes | No | No |
Note: Nutritional values for cheese are estimates and vary by type and brand.
Versatile Uses in a Low-Calorie Diet
Incorporating nutritional yeast into your cooking is straightforward and can help maintain a low-calorie diet while satisfying cravings for cheesy, savory flavors.
A Few Simple Culinary Ideas
- Sprinkle on Popcorn: A classic use for nooch, adding a cheesy, salty flavor without the fat and calories of butter or cheese.
- Make Vegan Cheese Sauces: Create a creamy, dairy-free sauce for pasta, potatoes, or steamed vegetables by blending nutritional yeast with a base of soaked cashews or flour.
- Enhance Soups and Stews: Stir into creamy soups or stews to add a savory, umami richness. It can also help to thicken the consistency.
- Roast Vegetables: Toss vegetables with a little olive oil and nutritional yeast before roasting for a cheesy, nutty crust.
- Boost Scrambles and Tofu: Sprinkle over scrambled eggs or a tofu scramble for added flavor and a nutritional boost.
Conclusion
In summary, 10 grams of nutritional yeast is a low-calorie powerhouse, providing a significant amount of protein and crucial B vitamins, especially when fortified with B12. With an average calorie count between 30 and 40 kcal per 10g serving, it serves as an excellent low-fat, high-flavor substitute for dairy cheese in numerous recipes. For anyone looking to reduce their caloric intake while increasing their nutrient density, nutritional yeast is an effective and versatile dietary ally. Its wide range of applications from popcorn topping to creamy sauces makes it a simple addition to any healthy eating plan.

Is Nutritional Yeast Right For You?
Nutritional yeast offers many benefits, but it's not suitable for everyone. Individuals with inflammatory bowel disease, glaucoma, or certain yeast sensitivities should consult a doctor before incorporating it into their diet. People with a higher risk of gout may also need to be cautious due to the purine content in yeast. As with any dietary change, moderation and consideration of personal health are key.
Choosing the Best Nutritional Yeast
When purchasing nutritional yeast, remember to check the label for fortification, particularly for Vitamin B12, if you are relying on it as a primary source. Fortified varieties offer the most comprehensive nutritional profile. Pay attention to serving size suggestions to ensure you get the intended nutritional benefits without over-consuming. You can find nutritional yeast in most health food stores and well-stocked supermarkets, often in flake or powder form.
How Nutritional Yeast Compares to Other Yeasts
It is important to differentiate nutritional yeast from other types. Unlike brewer's yeast, which is a byproduct of brewing beer and often has a bitter taste, nutritional yeast is grown specifically for consumption and is deactivated, so it can't be used for baking. Baker's yeast, conversely, is an active yeast used to make bread rise. Understanding these differences helps in using the correct product for your culinary needs.
Storage and Shelf Life
Properly storing nutritional yeast is simple. Keep it in a cool, dark, and dry place in a well-sealed container. It has a long shelf life, often lasting up to two years, ensuring you can enjoy its benefits over a long period.
