Natto (nattokinase)
Natto is a traditional Japanese food made from fermented soybeans, and nattokinase is a potent blood-clot dissolving protein produced by the bacterium Bacillus subtilis during the fermentation process. Nattokinase has been extensively studied for its potential health benefits, particularly in the prevention of cardiovascular disease.
Production and Characteristics
Nattokinase is found in the sticky part of Natto, which is made by fermenting boiled soybeans with the bacteria Bacillus subtilis. The enzyme is responsible for degrading fibrin proteins, which are a cause of thrombi. The level of nattokinase activity in commercially available Natto foods varies, and the activity level can decrease due to cooking or preparation methods. However, dietary supplements often offer a more stable level of nattokinase activity.
Health Benefits
Nattokinase has been studied for its potential health benefits, including:
Thinning the blood and breaking up blood clots, which may protect against heart disease and conditions caused by blood clots, such as stroke and heart attack Increasing the activities of naturally occurring proteins in the body, such as tissue plasminogen activator (tPA) and urokinase, which may help prevent cardiovascular disease Side Effects and Precautions
While nattokinase side effects are generally mild, it may increase the risk of bleeding. It is recommended to consult with a healthcare provider to determine the appropriate dosage and potential interactions with other medications. Additionally, nattokinase may not be suitable for pregnant or breastfeeding individuals, as there is limited information on its effects and safety in these populations.
Conclusion
Natto (nattokinase) is a traditional Japanese food with potential health benefits, particularly in the prevention of cardiovascular disease. While it is generally considered safe, it is essential to consult with a healthcare provider before adding it to your diet or using it as a supplement.
It does not taste good but is eminently available as capsules which taste like capsules. Take it as it says on the bottle. You can get it as a food additive in a Japanese or other East Asian food store but it requires patience and fortitude until your taste buds are properly trained, sort of like double salted licorice which has no known benefits except that no one will ask you for any.
