“Ironclad” Heart Health With The Secret of Japan’s Samurai
For centuries, Japanese families buried bundles bound in rice straw in the ground. After a week or so, they would dig these bundles up, and serve the contents at meals. Inside the straw was a food prized by Samurai warriors. A secret that goes back some 1,000 years…
Today, it’s recognized as one of the great heart-health discoveries of the 20th century. Nobody knew why this food was so good for you until 1987, when a Japanese scientist uncovered its secret.
A heart-health secret we’ve captured for you in Best Life Herbals’ Nattokinase.
Here’s the story of this Samurai secret… and the many heart-health benefits it offers.
The Warrior Food Discovered by Accident
Some 1,000 years ago, a Samurai general and his officers sat by the campfire. Spent after a hard day of battle, they were boiling soybeans to feed their horses.
Suddenly, someone raised the alarm. The enemy had launched a sneak attack under cover of darkness. The general and his men broke camp, dumped the horses’ food in a rice straw bag, and fled into the night.
As dawn arrived, they finally rested. One of the officers fetched the bag of soybeans for their now-exhausted horses. Inside the bag, instead of just boiled beans, was a sticky mess.
But the men were as hungry as their horses… and it smelled slightly sweet. They tasted the goopy beans. They were good! That morning, the horses shared their meal with their hungry riders… and natto was born.
Or so goes the story. We know natto has been around for about 1,000 years. We also know the Japanese are among the longest-lived people on Earth. And have far fewer heart problems than Americans.
Just 20 years ago – in 1987 – scientists proved natto was part of the reason. It contains a unique enzyme called nattokinase.
But this enzyme isn’t found in soybeans. It can only be made when you combine soybeans with something else.
The Rice Straw Secret
Studies show nattokinase breaks up clumps of protein fibers that form in your blood stream. These clumps can lead to blocked arteries or free-floating clots. And either one is bad news for your heart.
But why does natto contain nattokinase? Other forms of soy don’t have it. That’s where the rice straw comes in.
The Japanese discovered boiled soybeans only become natto when they’re packed in rice straw. Rice straw had an almost “magical” effect. You couldn’t get natto any other way. But when you wrapped the boiled soybeans in rice straw, you always got natto.
Now we know it’s because of a bacterium that lives on the rice straw. It reacts with boiled soybeans. In fact, it ferments them. The result is natto… and the formation of nattokinase.
And 30 years of research shows nattokinase offers remarkable heart-health benefits.
Fighting Dangerous Clots
When you cut your hand (or any other part), one of your body’s first reactions is to rush a compound called fibrinogen to the wound. Fibrinogen then forms a protein called fibrin, which forms into a sort of mesh. Blood cells build up on this mesh and dry, forming a clot.
It’s a marvelously effective defense. But the process sometimes gets started without the cut.
For instance, widespread low-level irritation – which may be caused by stress, a poor diet, or any number of other problems – may trigger the release of unnecessary fibrinogen.
The resulting fibrin meshes may form partial blockages in blood vessels or tiny free-floating clots. Both can lead to serious health effects.
In a 2015 study, Japanese and U.S. scientists found just a single dose of nattokinase makes a difference. Within hours of taking a dose of the enzyme, volunteers’ blood showed signs of the breakdown of fibrin and at least two key clotting factors.
Perhaps more importantly, blood levels of these important compounds never dropped below normal.1
In 2006, doctors at the University of Southern California tested nattokinase on blood samples. They found the enzyme “thinned” blood and discouraged abnormal clumping of red blood cells.2
A research team in Taiwan tested nattokinase with human volunteers. After 8 weeks, all the volunteers showed lower levels of fibrin, and the two key clotting factors mentioned above.
But in volunteers at risk of heart trouble, the drop of fibrin was the highest – a remarkable 10% decrease.3
And that’s not the only way nattokinase promotes heart health.
The Evidence for Blood Pressure Support
You’ve probably heard 1,000 times how high blood pressure puts your heart at risk. And it’s a remarkably common problem. Which is another good reason to consider nattokinase.
Because several studies have found this enzyme supports healthy blood pressure levels.
A Korean study looked at 86 adults aged 20 – 80. For 8 weeks the volunteers took either nattokinase or a placebo. Until the study was done, neither the doctors nor the volunteers knew who was taking what.
After the 8 weeks, the nattokinase had a significantly greater drop in blood pressure than the placebo group. And the drop occurred in both systolic and diastolic readings.4
In 2011, scientists at Hiroshima International University tested nattokinase on animals with high blood pressure.
Over the course of the study, the subjects eating the enzyme-enhanced diet saw drops in systolic and diastolic blood pressure. Their fibrinogen levels also dropped. Subjects eating a normal diet didn’t see these improvements.5
U.S. researchers tested nattokinase on 74 volunteers with high blood pressure. Half took the enzyme, while the other half got a placebo. At the end of the study, the nattokinase group showed improvements the placebo group didn’t.
In this study, men seemed to see a greater benefit than women… but both saw healthier blood pressure levels after taking nattokinase.
Other studies suggest nattokinase may boost heart health in even more ways.
“Bonus” Heart Benefits From Nattokinase
We’ve only known about this amazing enzyme for 30 years. But evidence is piling up for its heart-health benefits. Here are just a few studies that point to nattokinase as an overall heart defender…
- Cholesterol – Chinese doctors tested nattokinase on volunteers for 8 weeks. Volunteers taking nattokinase saw a much bigger drop in total cholesterol than those taking a placebo.7
- Arterial thickening – One of the early signs of blocked arteries is thickening of the artery walls. In an animal study, Japanese doctors discovered taking nattokinase regularly may defend against the thickening process.8
- Blocked arteries – Scientists in China gave nattokinase to volunteers with partially blocked arteries. After 26 weeks, the blockages were less, and their total cholesterol levels were lower.9
Perhaps best of all, nattokinase is 100% natural – and is backed by a 1,000-year safety record.
