We are eating poison every day.

The poison is none other than 'vegetable oil'!

Modern people's tables have long been filled with the message that "healthy fats are vegetable oils."
Doctors, nutritionists, and textbooks have all said the same thing.
To reduce cholesterol, it has been recommended to use vegetable oils instead of animal fats.
But what has been the result? The world is now facing an epidemic of unmanageable chronic diseases, including obesity, diabetes, high blood pressure, cardiovascular disease, Alzheimer's, depression, and autism.

This book, The Betrayal of Vegetable Oils, exposes the true nature of this silent catastrophe.
The author, Dr. Catherine Shanahan, is a leading expert in the field of functional medicine, working as a physician, biochemist, and nutritionist in the United States and has experience as a dietary advisor to an NBA team.
Drawing on her extensive clinical experience and biochemical research, she meticulously demonstrates, through scientific data and historical context, how the vegetable oils we consume every day have become "chronic disease generators."

A colorless and odorless substance that accounts for 30% of the calories consumed by modern people
Vegetable oil is the 'dark calorie' of modern people!

Vegetable oils are colorless, odorless, and tasteless, so they don't seem harmful on the outside, but they are actually a secret hazard that accounts for about 30 percent of the calories we eat.
The fact that "at least one type of vegetable oil can be found in the ingredients list of over 80 percent of foods" is a warning that we are constantly exposed to vegetable oils without even realizing it.

The crux of the problem is polyunsaturated fatty acids (PUFAs).
The "bad eight" vegetable oils, including canola oil, grapeseed oil, soybean oil, corn oil, sunflower oil, cottonseed oil, safflower oil, and rice bran oil, are high in PUFAs.
This oil is refined, deodorized, and treated with chemicals in factories.
A single drop of oil undergoes more than 40 industrial processes, resulting in a mass of unstable fatty acids that are prone to oxidation.
When this oil enters our body, it attacks cell membranes, causes oxidative stress, induces inflammation, increases insulin resistance, and destroys the brain nerves and immune system.
This causes a wide range of 'unexplained symptoms' including fatigue, insomnia, headaches, obesity, depression, skin problems, and poor concentration, but most people don't think the oil is the cause.
The author says, "The true nature of vegetable oil is dark calories.
He describes it as "the 'dark calories' of the table," and points out the structural blind spot where this oil, which causes disease, goes unnoticed by the medical community.

The sicker you get, the richer they get.
The Collusion of Distorted Medicine and Industry: Why Vegetable Oils Became "Healthy Oils"

The belief that vegetable oils are good for you is the result of marketing and industry collusion, not science.
The author attributes all this chaos to "the collusion between the vegetable oil industry and the medical establishment that has existed since just after World War II."
The book details how vegetable oils were first developed for industrial use and how organized lobbying was conducted to convert them into food.
Nutrition textbooks, public guidelines, physician training programs, large hospitals, food company advertising and packaging claims—all these have contributed to the portrayal of vegetable oils as "healthy fats."

Vegetable oils are not taught in medical curricula, and research funding and access to resources are biased in certain directions.
Doctors are forced to follow practice guidelines under the health insurance system, and those guidelines are subject to industry influence.
Therefore, doctors are structured in such a way that they cannot help but be subordinate to the interests of the system rather than the health of the patients.
Moreover, while we repeat the old narrative that “cholesterol is the problem,” it is actually polyunsaturated fatty acids that threaten our health.
The author says:
"Even healthy people undergo annual health checkups, paving the way for lifelong illness." Under the guise of health, we were ingesting poison every day.

What to remove and what to put on your table
The ultimate 'diet detox' plan to restore your natural, true health.

The author stumbled upon the problem of vegetable oils while struggling with his own serious illness, and has since experienced remarkable changes as he has improved his diet with NBA players, college basketball teams, and renowned doctors.
"Who would believe that I could improve this much in just two weeks by cutting out vegetable oil? I wouldn't believe it either," a famous broadcaster said, exemplifying a typical response from a real-life recovery story.

As the team began to see noticeable results, including faster recovery times and improved energy, other NBA teams, including the Los Angeles Lakers, Golden State Warriors, and Oklahoma City Thunder, followed suit.
The anecdote that "Kyle Lowry quit vegetable oil immediately after signing and led the team to a championship that year" symbolically shows the impact such a change can have on individual and organizational performance.

《The Betrayal of Vegetable Oils》 presents a practical path to 'diet detoxification'.
The second half of the book contains a two-week diet detox plan.
This plan isn't simply about "cutting out oil."
It's a practical guide to health restoration that clearly tells you what to remove from your diet and what to put in, and biochemically explains the stages of your body's recovery.
There's no need for complicated recipes or expensive supplements.
From now on, you only need to change one oil.
In just two weeks, your body will begin to respond.

The root cause of all the problems you experience—fatigue, inflammation, brain fog, depression, obesity, high blood pressure, diabetes, fatty liver—may lie in vegetable oils.
And now we can cut that thread.
《The Betrayal of Vegetable Oils》 is not just a health book.
This book is a social indictment that shows how the health common sense we take for granted can be distorted and manipulated. It is also a guide to breaking free from that false health and beginning true recovery and healing.
The road to regaining health is not grand.
It starts right now, by changing the oil on your table.
That small, powerful choice will change your entire life.

In an age where people who follow diets that doctors confidently believe are healthy are falling ill, your health decline isn't simply the result of ignorance.
It is the result of structural deception and consumer manipulation.
The author earnestly hopes that this book will spark a health revolution that will drive out vegetable oils.

Recommendation

People tend to regard the products of modern science as complete truth.
When pointing out the harmful effects of seed oil, people ask, “How can edible oil that has passed the food standards set by the government be that bad?”
But the numbers on your report card never guarantee your health.
This book compellingly tells the story of how vegetable oils came to be and the vested interests behind them. It delves into PUFAs in depth, yet presents them from a life science perspective in an accessible manner. It also explains why the medical industry isn't interested in helping you "restore your health."
Since I started eliminating vegetable oils, I've been freed from chronic conditions I thought were incurable, and I've regained control of my healthy lifestyle, rather than dwelling on the vague fear of illness as I age.
I don't want to experience this miracle alone.
I sincerely hope that many people will relate to the message of this book.
― Nickname: Himi, a 20-year-old who completely stopped eating vegetable oil and all her insomnia, polycystic ovary syndrome, and rhinitis improved.

Since I was young, there was no place on my body that was clean.
While childhood obesity led to adult obesity, I lived with dermatitis of unknown cause, taking antihistamines and steroids, and suffered from chronic rhinitis and sinusitis.
If you say that all these symptoms disappeared after you stopped eating vegetable 'seed oils', no one will believe you.
The author clearly explains why these miracles were possible through controlled experiments and chemical and biological mechanisms.
“So, are you saying all the cooking oils on display at the supermarket are food waste?” No, this book starts from the fact that they were never ‘food’ in the first place.
― Nickname: Jay, lost 24kg in 7 months by quitting vegetable oil, completely quitting vegetable oil

I had given up on acne, thinking it was due to my constitution, but after learning about the harmful effects of vegetable oil, I threw away all the oil in my house and stopped using it. My skin changed dramatically.
The terrible pustular acne had disappeared, and after a few months, not even the smallest pimples could be found.
I am a police officer who works shifts.
I was always tired and suffered from minor illnesses, and I thought that was also due to my constitution.
But after I stopped eating vegetable oil, my fatigue decreased and my cold disappeared.
Only then did I realize.
The real reason I was sick was not my body, but the oil.
To my younger sibling who used to ask, “If it’s harmful, why would they sell it in the supermarket?” this book will now provide a clear answer.
It contains the shocking truth about why vegetable oils are dangerous and how they are disguised as health foods.
This book clearly shows that vegetable oil is not just cooking oil, but the main culprit that destroys our bodies.
Just changing one oil can change your life.
― Nickname: Honey Meow, a 30-year-old who stopped eating vegetable oil and got rid of acne and minor ailments.

I've heard from many sources that vegetable oils are bad for you, but I didn't really understand what the problem was or why it caused these results.
This book explains in detail and logically how vegetable oils are manufactured, the oxidation process, and how oxidative stress causes inflammation and causes disease throughout the body.
If you find yourself wondering, “Why is that?” while reading, the question will be naturally resolved in the next chapter, and you will experience the blurry puzzle pieces falling into place clearly.
I highly recommend this to anyone who wants to know the root cause of why vegetable oils are harmful.
―Nickname: Thomas, a 30-year-old who quits vegetable oil to improve obesity and lethargy.

As a young diabetic, this book gave me the best insight.
I read every book on diabetes in the library, but no one told me anything I'd never heard before.
All they did was emphasize advice to increase vegetables and unsaturated fats, and post-exposure measures like a reverse diet. Although I'd been tested numerous times at the hospital, and surprisingly, my levels were always within the normal range, Catherine Shanahan was the first doctor to tell me I had insulin resistance.
I'm glad I finally met a serious doctor who gave me a convincing explanation of my irrational blood sugar levels and health issues, which were always diagnosed as "unknown cause" or "stress," focusing on PUFAs.
We cannot escape death, but we do have the right to reject the poisons created by mankind.
I strongly recommend this book to anyone who wants to regain their lost health.
― Nickname: Milky Joy, cut off vegetable oil

This book asks you, who have been choosing canola oil over butter and 'healthy' vegetable oils over animal fats:
"But why was my body always tired and inflamed?" This book scientifically uncovers that the common sense we've believed in is actually a huge misunderstanding created by the food industry and the medical community.
If you've been struggling to find the cause of your chronic fatigue and pain, this book will bring a small revolution to your diet and amazing recovery to your body.
― Nickname: Gogirakani, quitting vegetable oil

The privileged class dominates the discourse on nutrition based on theories and papers published in the medical and scientific communities.
As a result, the vegetable oil manufacturing industry is thriving, and the pharmaceutical industry is also growing thanks to the health problems caused by vegetable oil consumption.
In a social structure where such a vicious cycle repeats itself, this book presents specific ways to protect one's own health by opposing the hegemony of the privileged class.
We hope that small changes starting in the kitchen will empower you to reflect on your eating habits and make better choices.
― Nickname: Dusty, a 30-year-old who completely stopped eating vegetable oil and had autoimmune and inflammatory bowel diseases disappear.

Sometimes my mind is so full of thoughts about food that I can't focus on anything else but eating.
But it's quite shocking to learn that this loss of self-control may not be due to simple gluttony or lack of willpower, but rather a symptom of low blood sugar.
What's even more surprising is that the cause may be hidden in vegetable oils (seed oils) and numerous processed foods that we use in our daily cooking, believing they are healthy.
This book challenges the assumptions we take for granted about diet.
If you are a modern person pursuing well-being, you should learn again what 'truly healthy fat' is through this book.
― Nickname Jolie, completely cut out vegetable oil and became listless? A 30-year-old who has overcome bulimia.

This book, which scientifically reveals the truth about vegetable oil, which has long been believed to be a symbol of health, was a refreshing shock.
When I learned of the harmful effects of vegetable oils, hidden under the shadowy thumb of multinational food corporations, through radical theory and genetic perspectives, I was able to feel anew the nobility of animal fats, which had been looked down upon, and the greatness of nature's creations.
This book, which makes us question and rethink the truths we have believed in throughout our lives, can be boldly called a 'guide to life.'
If the human diet follows the natural order, it will naturally become healthy.
Using this book as a springboard, let's take a step further by questioning, not just exclamation, the knowledge we already know.
