From Kitchen Staple to Nutritional Powerhouse: Exploring the Benefits of Nutritional Yeast

What is Nutritional Yeast?

Nutritional yeast is a type of deactivated yeast. It is grown on molasses and can be used like any other spice or condiment. Nutritional yeast has a nutty, cheese-like flavor and is commonly used as a flavor enhancer or cheese alternative due its savory flavor. The yeast is grown in large vats and then harvested, washed and dried. These days, nutritional yeast is primarily recommended as a supplement rather than a complete diet.

Nutritional Value of Yeast

Nutritional yeast is a highly nutritious food that is rich in several important vitamins and minerals. A one tablespoon serving of nutritional yeast contains:

- Protein (4 grams) - Nutritional Yeast is a great non-dairy source of complete protein that contains all essential amino acids. This makes it a suitable protein alternative for vegans.

- B-vitamins - It is exceptionally rich in B-vitamins like riboflavin (B2), niacin (B3), pyridoxine (B6) and folate. These B-vitamins help support energy production and metabolism.

- Minerals - It also contains minerals like selenium, iron and zinc in significant amounts that are beneficial for overall health and wellness.

- Fiber - One tablespoon of nutritional yeast provides about 1 gram of fiber which aids in digestion and heart health.

- Healthier unsaturated fats - Unlike regular yeast which contains unhealthy saturated fats, nutritional yeast is low in fat and contains heart-friendly unsaturated fatty acids.

Given its nutritional density, nutritional yeast is considered a highly functional food. Its rich vitamin and mineral profile makes it an excellent substitute for dairy, meat, and other animal products for vegans and vegetarians.

Health Benefits of Nutritional Yeast

1. Supports Heart Health

The abundance of B-vitamins like folate and vitamins B6, B12 and minerals like selenium in nutritional yeast help lower homocysteine and reduce the risk of heart diseases. The fiber and healthy fats also help regulate cholesterol levels and blood pressure.

2. Boosts Metabolism and Energy levels

Being packed with riboflavin, niacin and other B-complex vitamins, nutritional yeast is vital for carbohydrate, fat and protein metabolism in the body. This helps increase energy levels naturally.

3. Supports Bone Health

Nutritional yeast contains valuable minerals like calcium, magnesium, zinc and copper that support bone mineral density. Adequate intake can reduce the risk of osteoporosis and age-related bone loss.

4. May Aid Weight Loss

The protein and fiber content in nutritional yeast helps enhance satiety and reduces appetite. For this reason, incorporating nutritional yeast into the diet may support healthy weight management efforts.

5. Supports Immune Function

The selenium, zinc and vitamin B6 in nutritional yeast reinforce immune defenses against infections and diseases. It could lower the risk of respiratory illnesses.

Forms and Ways to Use Nutritional Yeast

Powdered or Flakes:

Nutritional yeast usually comes in the form of yellow flakes or powder. It can be easily stored in an airtight jar on the kitchen counter for future use. Due to its cheesy flavor, it is commonly used as a cheese alternative or flavor enhancer. It pairs well with popcorn, pasta, roasted vegetables, salads, dips and sauces.

Seasoning Blends:

Many brands also offer pre-made seasoning blends with nutritional yeast as the base ingredient. Popular ones are nutritional yeast seasoning with garlic powder, onion powder, salt for pizza, fries or popcorn. These blends allow people to easily add nutritional yeast's boost of umami and cheesy flavor profile to favorite recipes.

Supplements:

Nutritional yeast supplements exist in capsule and tablet form for people seeking its vitamin and mineral profile. These serve as convenient alternatives for those who don't use or like the flavor of nutritional yeast directly in cooking. Supplements allow reaping its benefits without having to consume it as food.

One thing to note is that not all nutritional yeast products are fortified equally. Brands that use the ‘Living Food’ method retain most naturally-occurring B-vitamins, while artificially fortified varieties may contain additional synthetic vitamins. Choosing minimally processed nutritional yeast from reputed brands is ideal.

Factors to Consider Before Using Nutritional Yeast

While nutritional yeast boasts many health advantages, some factors are worth considering:

- Allergies: People with yeast allergies may experience discomfort after consuming it. Similarly, those allergic to nutritional yeast should avoid it.

- B12 intake: Nutritional yeast is typically promoted as a non-meat source of B12. But frequent laboratory testing shows some brands may contain no active B12. Strict vegans need vitamin B12 supplements.

- Effect on blood thinning medications: The vitamin K content in nutritional yeast is negligible. However, those on blood thinners must check with a doctor before adding it to their diet.

- Amount and cooking method: Consuming more than the recommended one tablespoon serving of uncooked nutritional yeast may cause indigestion and bloating in some people. Gentle cooking helps improve digestibility.

- Interactions with certain medications unknown: Research on potential drug interactions is lacking. Caution is recommended especially if nutritional yeast intake is increased or decreased drastically while on prescription drugs. Medical supervision is best.
