“Indigestion is the root of all diseases!”
A meal that provides both nutrition and detoxification
How to revive my broken body!

When I was working as a new drug development researcher, the author had several questions.
Modern medicine and science have advanced at the speed of light, but ironically, the types of diseases and the number of patients are increasing, and chronic diseases account for 80% of deaths worldwide.
In our country, the population suffering from diabetes and pre-diabetes, which are representative chronic diseases, has exceeded 51%.

Modern medicine approaches chronic diseases as if it were emergency treatment, aiming only at temporary symptom relief.
The solution that seeks to get to the root of the problem is entirely up to the individual.
I also used to think that medicine was the best treatment.
However, when we focused our research on 'health' rather than medicine, the root of the problem began to become more apparent.

Everyone wants to maintain a healthy and slim body.
The way to become healthy must be found in the laws of nature, not in science.
Overly complex science, medicine, and nutrition are actually making us sick.
Even foods that we believe are full of nutrients can turn out to be poisonous.
In fact, excessive intake of carbohydrates, proteins, and fats can lead to serious nutritional imbalances and adult diseases.

If the cause of all diseases starts from what you eat, you can get better by eating again.
The purpose of this book is to improve the eating habits of modern people who suffer from serious nutritional imbalance due to a diet centered on rice, bread, and meat.
We will talk about how to properly nourish and detoxify the digestive organs, especially the stomach, liver, intestines, and pancreas.
And at the heart of that solution is fruit.

“Just eat 3 pieces of fruit on an empty stomach in the morning and 1 piece of fruit before meals!”
Lifelong habits of people who live long and healthy lives
The best diet to live a long and healthy life

The author studied the cases of people who lived long and healthy lives.
And we found that the longer a person lives in good health, the stronger their digestive system, which extends from the stomach to the liver to the intestines and pancreas, is.
They never suffered from illness even if they did not take medicine or eat health food.
Instead, I ate fruit in the morning, fruit before lunch and dinner, and ate simple meals mainly consisting of brown rice and raw vegetables.
In this way, the natural eating habits with living enzymes kept the stomach, which is responsible for digestion, the liver, which is responsible for detoxification, and the intestines, which are responsible for absorption and excretion, strong.

People with strong digestive systems have a healthy metabolism from head to toe, so they don't gain weight.
I maintained a slim and healthy body by eating until I was full without having to diet separately.
Because my bowel movements were active, I never suffered from constipation, and I never complained of chronic fatigue.
This is because the dietary fiber, antioxidants, and essential amino acids abundant in fruits and vegetables maximize the body's functions.
The natural, fully digestible diet, which supplies our bodies with living enzymes, has been proven effective in treating various diseases through the treatment of the world's top doctors, including former President Clinton's personal physician John McDougall, Hiromi Shinya, and Colin Campbell.
In fact, it has been confirmed that people who eat fruits and brown rice have lower blood sugar levels and are cured of various adult diseases such as hyperlipidemia, high blood pressure, and obesity.

The revised and expanded edition of the health bestseller "Complete Digestion" has been published!
A viral video with over 10 million views! The originator of the "fruit breakfast" reveals the secrets of natural eating!

Since its first publication in 2018, "Complete Digestion" has quickly become a #1 health bestseller, capturing readers' attention.
Since then, it has been a bestseller and has shown steady interest until 2019, and since 2023, it has been continuously appearing in 'You and My Retirement School', recording 5.3 million views in one video and causing a huge stir with the cumulative views reaching 10 million.
Thanks to the enthusiastic support of readers, a revised and expanded edition was published after six years.

In this revised and expanded edition, pancreatic health methods have been added to the existing stomach-liver-intestine methods.


More than half of the Korean population, approximately 22.48 million people, have diabetes or are in the pre-diabetic stage.
As of 2022, diabetes is the 8th leading cause of death in Korea and the 7th leading cause of death in the United States.
Moreover, it is a chronic disease that cannot be overlooked as it can easily lead to painful complications.
Diabetes is most closely related to the pancreas, because when an autoimmune reaction occurs in the beta cells of the pancreas, insulin, which transports sugar throughout the body, is not secreted.


The book points out that eating refined white rice three times a day is the main cause of damage to the pancreas, an important organ.
This is why Koreans, who need to eat rice to gain strength, are prone to diabetes.
To prevent this, we will discuss what eating habits will be helpful through the ‘cellular detox diet.’

Additionally, the revised and expanded edition includes a variety of appendices for those starting a natural fruit diet.
It includes 'Fruit combinations when eaten with different types of fruit', 'Step-by-step main diet for those starting a fruit diet', and '4 habits practiced by long-lived people' selected by researching the diets and lifestyles of people in longevity villages around the world.
