Epilogue 324

The importance of long-term leakage as revealed by the New York Times,
A healthy gut is essential for a healthy life!

“Many of the diseases that modern people suffer from are caused by intestinal leaks.”
- Chris Cressey, New York Times bestselling author of Your Paleo Code

“Most of the patients I met had severe leaky gut problems.

“We have seen cases where other treatments did not work, but were completely cured through gut leak treatment.”
- Mark Hyman Box, eight-time New York Times bestselling author

The term 'leakage of intestines' probably sounds unfamiliar to most people.
Although it has recently become a hot topic and been introduced in the media as a 'leaky gut syndrome', there are still not many people who know the details about leaky gut.
This is because leaky gut is actually a serious cause of disease, but the medical community is overlooking this fact.
However, some experts in the United States, who were looking for the hidden causes of the disease, have recently started to inform the medical community about the effects of leaky gut after conducting in-depth research on it.
This became an issue when the New York Times' bestselling health authors wrote articles related to 'leaky gut'.

The intestines play a very important role in our body, as evidenced by the fact that Hippocrates said 2000 years ago, “All disease begins in the intestines.”
If your gut is healthy, you can live a healthy life free of disease, but if your gut health is disrupted, a domino effect of disease begins.
Unfortunately, however, only a very small number of people maintain good intestinal health.
Our intestines, which are now at extreme risk due to modern people's westernized diet, stress, and drug abuse, are finally on the verge of developing holes.


In this situation, the author has been treating patients with chronic diseases, focusing on the fact that what modern people need most is 'root cause treatment' of the disease, and through numerous successful experiences, he has finally come to realize that 'leaky gut' is the root cause.
Gut health is the root of all diseases and the key to treatment.
This book contains detailed information on how to protect our intestines from intestinal leakage.

If you don't treat the leaky gut, you can't cure any disease!

Leaky gut literally means a condition in which a hole develops in our intestines and leaks.
What happens to our bodies if the intestinal wall becomes inflamed and perforated by various stimuli within the intestines, or if the intestinal wall remains open? Undigested food particles that pass through the intestines will become toxic to our bodies.
These toxins travel through the bloodstream to various parts of the body and cause inflammation in the weakest parts of the body, which in turn leads to various systemic diseases.
The author calls this the “domino effect of systemic disease.”
If this condition persists, multiple diseases will appear simultaneously, not just one.
This can eventually lead to psychological illness.
Many people go to many hospitals until their body reaches this point, but in the end, they give up without finding a treatment method.
However, all of these diseases can be treated by 'blocking the intestinal leakage.'


So how do we know if we have a leaky gut? It's no exaggeration to say that the symptom we often feel, "indigestion," is the first sign of a leaky gut.
But many people ignore these signals and leave their bodies untreated.
Eventually, when symptoms worsen, we go to the hospital, but in most cases, our body has become so severe that it cannot be cured with temporary treatment alone.
When you experience mild symptoms such as 'indigestion', 'extreme fatigue', 'persistent pain', or 'your body feels different than before', you should suspect a leaky gut and seek treatment immediately to protect yourself from serious illness.

No matter how good the nutritional supplements you take, if you have leaky gut, it's like flushing a lot of money down the toilet.
Medication prescribed to relieve painful symptoms may have a temporary effect, but in the long run, it will only make the illness worse.
No matter how much you cry out in pain, “Please don’t hurt me,” you cannot find a fundamental solution.
There is only one way, 'to prevent the leakage of intestines'.

The author dares to assert:
“99% of all diseases are caused by leaky gut.”
This means that maintaining intestinal health and treating leaky gut are important.
In this book, we will learn how to restore the health of our gut, often called the second brain, and keep our brain and body healthy throughout our lives.
