Is Nutritional Yeast Healthy? All You Need to Know

What is nutritional yeast?

Nutritional yeast, often referred to as "nooch," is a popular dietary supplement known for its rich nutrient profile and unique flavor. This deactivated yeast, typically derived from Saccharomyces cerevisiae, is celebrated for its health benefits, versatility in cooking, and savory taste reminiscent of cheese. Nutritional yeast is grown on molasses, then harvested, washed, and dried to deactivate the yeast. Unlike baker's or brewer's yeast, nutritional yeast does not leaven bread or brew beer. Its deactivation process ensures it won't cause yeast overgrowth in the body, making it safe for consumption even in larger quantities.

Nutritional Profile

Nutritional yeast is a powerhouse of essential nutrients, particularly beneficial for those following vegetarian or vegan diets. Its nutritional highlights include:

1. Protein: Contains all nine essential amino acids, making it a complete protein source. Typically, two tablespoons provide around 4-5 grams of protein.
2. B Vitamins: Rich in B vitamins, especially B12, which is crucial for vegans since B12 is primarily found in animal products.
3. Minerals: Contains trace minerals like zinc, selenium, and manganese.
4. Fiber: A good source of dietary fiber, aiding in digestion.
5. Antioxidants: Nutritional yeast contains the antioxidants glutathione and selenomethionine, which may protect your body from chronic diseases.

Health Benefits

1. Boosts Immunity: The beta-glucans in nutritional yeast have immune-enhancing properties.
2. Supports Energy Metabolism: High levels of B vitamins, especially B12, help convert food into energy.
3. Promotes Skin, Hair, and Nail Health: B vitamins and proteins support healthy skin, hair, and nails.
4. Aids Digestion: The fiber content promotes healthy digestion and regular bowel movements.
5. Potential Antioxidant Effects: Contains antioxidants that may help protect the body from oxidative stress and chronic diseases.

Conclusion

Nutritional yeast is a nutrient-dense, versatile ingredient that can enhance the flavor of many dishes while providing significant health benefits. Whether you’re a vegan looking for a source of B12, someone seeking to boost your protein intake, or just a foodie in search of a new culinary twist, nutritional yeast is a worthy addition to your pantry.
