What is Natto Powder?
Natto powder is a freeze-dried version of natto, a traditional Japanese food made by fermenting soybeans with the bacterium Bacillus subtilis var. natto. The process of freeze-drying involves rapidly freezing the fermented natto and then drying it under a vacuum to remove moisture, preserving its nutritional value without the strong smell or sticky texture of traditional natto. This makes natto powder a highly versatile ingredient for people who want the benefits of natto but find its original form and texture unappealing. A key advantage of the freeze-drying process is that it puts the beneficial Bacillus subtilis bacteria into a dormant, spore state, allowing them to survive the harsh acidity of the stomach and arrive intact in the intestines, where they can be most effective.
Nutritional Powerhouses in Natto Powder
While traditional natto is nutritious, the concentrated form of natto powder is a nutritional powerhouse, delivering high levels of specific beneficial compounds.
Nattokinase
Nattokinase is a unique enzyme produced during the fermentation of soybeans into natto. This potent enzyme is believed to have significant benefits for cardiovascular health due to its fibrinolytic properties, meaning it helps dissolve blood clots. This action helps maintain healthy blood flow and blood vessel structure. Studies suggest nattokinase can reduce blood pressure and may lower the risk of heart-related issues.
Vitamin K2 (Menaquinone-7)
Natto is one of the richest food sources of Vitamin K2, with natto powder containing a concentrated dose. Unlike Vitamin K1 found in leafy greens, K2 plays a vital role in bone health by activating proteins that help build and maintain strong bones. It is also crucial for heart health, as it helps prevent arterial calcification by directing calcium to the bones and away from the arteries. This makes natto powder an excellent supplement for maintaining bone density, especially for postmenopausal women.
Probiotics (Bacillus subtilis natto)
The fermentation of soybeans with Bacillus subtilis is what creates the probiotics in natto. In powdered form, these probiotics are highly stable and resilient. Once consumed, they contribute to a balanced and diverse gut microbiota, which is linked to a wide range of health benefits, from improved digestion and immunity to mood regulation.
Protein and Fiber
As a soy-based product, natto powder is an excellent source of high-quality plant protein and dietary fiber. This combination supports satiety, aids digestion, and can be a valuable component of a healthy diet, especially for those following a plant-based or vegan lifestyle.
What is natto powder good for? Major Health Benefits
The synergistic effect of natto powder's unique compounds provides a wide spectrum of health benefits.
Supports Cardiovascular Health
The enzyme nattokinase and ample Vitamin K2 content make natto powder a powerful ally for heart health. Nattokinase's ability to help dissolve blood clots, combined with Vitamin K2's role in keeping arteries clear, creates a dual-action benefit for blood pressure and circulation. The fiber and polyunsaturated fats also contribute by helping to manage cholesterol levels.
Promotes Stronger Bones
For individuals concerned about bone density, especially postmenopausal women, natto powder is a highly effective dietary addition. The concentrated Vitamin K2 (Menaquinone-7) helps activate bone-building proteins, while the ample calcium content provides the necessary building blocks for strong bones.
Improves Gut Health and Digestion
The spore-forming probiotics in natto powder effectively colonize the gut, promoting a healthier microbial balance. This can lead to better nutrient absorption and help alleviate common digestive issues like bloating, constipation, and diarrhea. The dietary fiber further supports regular and healthy bowel movements.
Boosts Immune Function
With a majority of the body's immune cells residing in the gut, a healthy microbiome is directly linked to a robust immune system. The probiotics in natto powder help ward off harmful bacteria and promote the production of natural antibodies. Some studies have even shown that regular consumption of natto powder can reduce the incidence of respiratory infections.
Aids Weight Management
As a high-protein, high-fiber food, natto powder promotes a feeling of fullness, which can help control appetite and support weight loss goals. Additionally, research suggests that a healthy gut microbiome, supported by probiotics, is associated with a lower body mass index and reduced fat mass.
How to Incorporate Natto Powder into Your Diet
Thanks to its mild flavor and versatility, natto powder is easy to add to many dishes:
- Smoothies: Blend a teaspoon into your morning fruit or protein smoothie for a nutritional boost.
- Soups and Sauces: Stir into miso soup, ramen, or add to pasta sauces for a rich, umami flavor.
- Rice Dishes: Sprinkle over warm rice, curry, or risotto.
- Dips and Dressings: Mix into mayonnaise, ketchup, or salad dressings.
- Yogurt: Stir into yogurt for added protein and probiotics.
- Baking: Add to breads or pastries for a savory twist and enhanced nutritional content.
Natto Powder vs. Traditional Natto
This table outlines the key differences between natto powder and traditional natto to help you decide which is right for you.
| Feature | Natto Powder | Traditional Natto |
|---|---|---|
| Flavor/Smell | Significantly milder; can be almost unnoticeable. | Pungent, nutty, and earthy; an acquired taste. |
| Texture | Fine, dry powder that dissolves or thickens liquids. | Sticky, stringy, and slimy due to the polyglutamic acid. |
| Convenience | Easy to store, travel with, and use in a variety of recipes. | Sold in refrigerated or frozen packets; less versatile in application. |
| Probiotic Delivery | Spore form of B. subtilis survives gastric acid better, reaching the intestines alive. | Vegetative cells may be damaged by stomach acid, limiting probiotic effect. |
| Use Case | Versatile supplement for smoothies, soups, and dressings. | Traditionally eaten over rice for breakfast or as a side dish. |
Important Considerations and Side Effects
While natto powder is generally safe for most people, some precautions are necessary. The high Vitamin K2 content means that individuals taking blood-thinning medication, such as Warfarin, should consult a doctor before use, as it can interfere with medication. People with soy allergies should also avoid natto products entirely. When first introducing natto powder into your diet, some mild digestive upset like gas or bloating can occur, especially for those not accustomed to high-fiber foods. It is best to start with small amounts and gradually increase your intake.
Conclusion
Natto powder is an exceptional superfood offering a concentrated dose of nutrients with immense health benefits. Its convenience and milder taste profile make it an excellent alternative for those who find traditional natto unappealing. From supporting cardiovascular health and strengthening bones to improving gut health and boosting the immune system, the benefits of incorporating natto powder into a regular diet are substantial. By simply adding this versatile powder to your daily meals, you can take a significant step towards improved wellness.
