The Hidden Dangers of Vegetable Oils

This documentary sheds light on the shocking truth behind the consumption of vegetable oils, revealing how they may be far more harmful to our health than previously thought. The film follows the history of these oils, their rise to ubiquity in our diets, and the serious implications for our long-term health. Let’s break down the key moments and insights covered in the documentary.

0:00 - The Switcheroo
The film opens by describing what the creators call "The Switcheroo"—a shift in public perception that occurred in the mid-20th century. Animal fats, which had been a dietary staple for centuries, were suddenly demonized, while vegetable oils were promoted as a heart-healthy alternative. This switch, the documentary argues, was based on questionable science and driven by powerful food and medical organizations.

1:52 - History of Vegetable Oils
The documentary delves into the origins of vegetable oils, originally introduced as cheap by-products of the industrial revolution. These oils, including canola, soybean, and corn oil, were never part of the human diet until modern processing techniques made them readily available. Despite their industrial beginnings, they quickly found their way into the food supply as replacements for butter and lard.

3:50 - Enter the American Heart Association
The American Heart Association (AHA) played a pivotal role in promoting vegetable oils as a healthier alternative to saturated fats. Backed by commercial interests, the AHA endorsed vegetable oils to help reduce cholesterol and prevent heart disease. The film points out, however, that this was based on flawed studies that failed to address the negative long-term effects of these oils.

5:27 - The Massive Increase in Vegetable Oil Consumption
Since the mid-20th century, the consumption of vegetable oils has skyrocketed. The documentary highlights data showing a dramatic increase in the use of vegetable oils in processed foods, leading to widespread exposure to their harmful effects.

6:06 - Is Vegetable Oil Bad or Benign?
While some argue that vegetable oils are neutral or even beneficial, the documentary challenges this notion. It raises questions about whether these oils are truly benign, pointing to emerging evidence of their links to chronic diseases and oxidative stress in the body.

6:55 - Why do some animals live longer than others?
In this segment, the film explores how the types of fats consumed by different animals affect their longevity. Animals that consume saturated fats tend to live longer, while those that rely on polyunsaturated fats—like those found in vegetable oils—show shorter lifespans. This raises concerns about how human health might be impacted by the widespread use of these oils.

7:51 - Vegetable Oil Stays in Your Body for Years
The documentary provides startling information about how vegetable oils accumulate in our tissues and remain in the body for years. These oils are stored in fat cells and can lead to inflammation and oxidative damage over time, contributing to the development of various diseases.

9:11 - Hidden Data
Throughout the documentary, the creators expose hidden data that was either ignored or suppressed by the food and medical industries. This includes studies that revealed the harmful effects of vegetable oils but were never given public attention due to commercial interests.

12:08 - Vegetable Oils are in EVERYTHING
One of the most alarming points is just how pervasive vegetable oils have become. They are found in nearly all processed foods, from snacks to salad dressings. The documentary emphasizes how difficult it is to avoid these oils, making it almost impossible for consumers to make informed choices about their health.

13:07 - Why Vegetable Oils are Bad for Health
The film explains that vegetable oils are high in omega-6 fatty acids, which promote inflammation in the body when consumed in excess. Chronic inflammation is a known contributor to heart disease, cancer, and autoimmune conditions. The imbalance between omega-6 and omega-3 fatty acids in modern diets is a key factor in the negative health outcomes associated with vegetable oil consumption.

15:04 - The Toxic Oxidation Products
When vegetable oils are heated, they produce toxic oxidation products, including aldehydes and other harmful compounds. These substances can damage cells, tissues, and DNA, increasing the risk of diseases such as cancer and neurodegenerative conditions. The film underscores the importance of avoiding fried foods cooked in vegetable oils.

16:28 - How Vegetable Oils are Made
The documentary offers a detailed look at the industrial process used to create vegetable oils, which involves high heat, chemical solvents, and deodorizers. This process strips the oils of any beneficial nutrients and creates harmful by-products. The film suggests that these oils are far from the "natural" products they are often marketed as.

18:33 - Are Vegetable Oils Linked to Alzheimer’s?
Emerging research is exploring the potential link between vegetable oils and Alzheimer’s disease. The documentary discusses how the inflammatory and oxidative properties of these oils may contribute to the development of neurodegenerative diseases by damaging brain cells over time.

20:06 - Mitochondria, The Powerhouse of the Cell
The film highlights the role of mitochondria—the cell’s energy producers—in relation to vegetable oil consumption. It argues that the toxic by-products of these oils can impair mitochondrial function, leading to reduced energy production, fatigue, and an increased risk of chronic illness.

24:35 - Most Studies on Vegetable Oils Aren’t Long Enough
Many studies that claim vegetable oils are safe are often too short to capture the long-term effects of consumption. The documentary argues that because these oils accumulate in the body over time, their health impacts may not become apparent until much later in life. Longer studies are needed to truly understand the risks.

26:04 - Why Aren’t More People Talking About This?
The documentary concludes by exploring why the dangers of vegetable oils are not more widely discussed. It points to conflicts of interest in the food and pharmaceutical industries, where financial incentives often overshadow public health concerns. Despite mounting evidence, the widespread promotion of vegetable oils continues, leaving consumers unaware of the potential harm.


The documentary presents a compelling case against the consumption of vegetable oils, revealing the hidden dangers of these seemingly harmless products. From their inflammatory effects to their role in chronic disease, the film makes a strong argument for rethinking the way we approach fats in our diet. With vegetable oils found in nearly every processed food, it’s important for consumers to be aware of the potential risks and seek healthier alternatives.
