SEED OILS – A Tale of Two AIs
The growing consensus is that seed oils are a cause of the diabetes and obesity
epidemic. Grok AI gave a lot of concise reasons why seed oils are bad for your health
while Chat GPT took an opposing view, citing the American Heart Association saying
they’re fine, omitting the issue of how seed oils are processed et al. To Chat GPT’s
credit, it did reply factually to my questions on hexane, a hydrocarbon from crude oil,
and its role in seed oil production. However, Chat GPT did NOT cite the other uses of
hexane that would make you scratch your head while eating your hexane spiked Chick-
fil-a sandwich. Enjoy.

The Impact of Seed Oils on Food Addiction: Destabilizing Natural Body Processes
In recent years, there has been growing concern over the role of seed oils in our diets,
particularly in relation to health issues like inflammation, heart disease, and now, food
addiction. Seed oils, including soybean, corn, canola, cottonseed, sunflower, and
safflower oils, are ubiquitous in processed foods, accounting for a significant portion of
the fats we consume. This article explores how these oils might contribute to food
addiction by destabilizing the body’s natural physiological processes.
Understanding Seed Oils
Seed oils are extracted from seeds, and unlike oils from fruits or nuts, they require
extensive processing. This process often involves high heat, solvents, and
deodorization, which can degrade the oil’s nutritional profile and introduce new chemical
compounds. The primary concern with these oils is their high content of omega-6 fatty
acids, particularly linoleic acid, which, in the modern diet, is consumed in
disproportionate amounts relative to omega-3 fatty acids.
Omega-6 and Omega-3 Imbalance
The human body requires both omega-6 and omega-3 fatty acids for normal growth and
functioning. However, the ideal ratio of omega-6 to omega-3 should be close to 1:1 or
4:1, but in Western diets, this ratio can be as high as 20:1 or even higher due to the
heavy reliance on seed oils. This imbalance is problematic because:
Inflammation: Omega-6 fatty acids promote inflammation, while omega-3s are anti-
inflammatory. Chronic inflammation can lead to numerous health issues, including
insulin resistance, which is a precursor to diabetes.
Brain Health: The brain is particularly sensitive to this imbalance. An excess of omega-6
can alter neurotransmitter function, potentially leading to mood disorders and behavioral
changes, including food cravings.
Link to Food Addiction
Food addiction shares many characteristics with drug addiction, including cravings, loss
of control over consumption, and continued use despite adverse consequences. Here’s
how seed oils might exacerbate these symptoms:
Dopamine Dysregulation: The consumption of foods rich in seed oils can lead to an
overproduction of dopamine, a neurotransmitter associated with pleasure and reward.
Over time, this can lead to a downregulation of dopamine receptors. As the body
becomes less sensitive to dopamine, individuals might seek out more of these foods to
achieve the same pleasure, leading to addictive behaviors.
Endocannabinoid System Disruption: Seed oils can influence the endocannabinoid
system (ECS), which regulates appetite, mood, and energy balance. An imbalance in
omega-6 and omega-3 can lead to an overactive ECS, increasing hunger and the desire
for palatable foods, which are often rich in these oils.
Hormonal Imbalance: High intake of linoleic acid from seed oils can affect hormone
levels, including those that regulate hunger like leptin and ghrelin. Leptin resistance,
where the brain does not respond properly to leptin’s signals to stop eating, can be
exacerbated by chronic inflammation from omega-6 fats, leading to overeating.
Destabilizing Body’s Natural Processes
The body has evolved with a balance of nutrients that supports health. However,
modern dietary patterns have shifted this balance:
Metabolic Function: Seed oils can impair mitochondrial function, leading to energy
inefficiency and increased fat storage. This metabolic disturbance can make individuals
feel less satiated, prompting more food intake.
Gut Health: The gut microbiome plays a crucial role in health and behavior. Diets high in
processed seed oils can alter gut bacteria composition, leading to dysbiosis. This
imbalance can influence mood, appetite, and even cravings, potentially driving food
addiction.
Detoxification Challenges: The body’s detoxification pathways can be overwhelmed by
the byproducts of seed oil processing, leading to oxidative stress and further metabolic
disturbances. This stress might contribute to cravings as the body seeks quick energy
from food to counteract fatigue or low mood.
Behavioral and Societal Implications
Marketing and Availability: Seed oils are cheap and have a long shelf life, making them
prevalent in fast foods and processed snacks, which are aggressively marketed. This
widespread availability and the palatability of foods containing these oils can lead to
habitual consumption, reinforcing addictive behaviors.
Cultural Shift in Diet: The shift from traditional diets rich in whole foods to modern diets
high in processed foods has coincided with an increase in obesity and related diseases.
This cultural dietary shift might be partially driven by the sensory appeal of foods high in
seed oils, which can lead to overconsumption.
Conclusion
The hypothesis that seed oils contribute to food addiction through destabilizing natural
body processes is compelling and backed by growing scientific interest. The
mechanisms involve complex interactions between diet, hormones, neurotransmitters,
and psychological factors. While more research is needed to fully understand these
connections, the current evidence suggests that reducing seed oil intake could be a
beneficial strategy in managing food addiction. This would involve not only dietary
changes but also a broader societal shift towards valuing and promoting whole,
unprocessed foods. As individuals become more aware of the implications of their
dietary choices, there’s potential for significant health benefits, including overcoming the
cycle of food addiction driven by modern dietary fats.
Is hexane used in the processing of seed oils?
Yes, hexane is commonly used in the processing of seed oils. It serves as a solvent to
extract oil from seeds like soybeans, canola, sunflower, and others. The process
involves soaking the seeds in hexane to dissolve the oil, which is then separated from
the solvent. After extraction, the hexane is typically removed through evaporation, but
trace amounts might remain in the final product. This method is widely used in the
industrial production of vegetable oils because it is efficient and cost-effective. However,
concerns have been raised about the health implications of residual hexane, leading to
regulations on permissible levels in food products.
What is hexane?
Hexane is a chemical solvent derived from crude oil. It is a clear, colorless liquid with a
slightly unpleasant odor, commonly used in industrial and laboratory settings.
Properties of Hexane:
Chemical formula: C₆H₁₄
Boiling point: ~69°C (156°F)
Highly flammable
Low water solubility
Volatile organic compound (VOC)
Common Uses of Hexane:
Oil extraction: Widely used to extract vegetable oils from seeds (like soybeans, canola,
and corn).
Adhesives and glues: Found in rubber cement and similar products.
Cleaning agents: Used as a solvent to clean machinery and electronics.
Laboratories: Employed as a solvent in various chemical reactions and
chromatography.
Textile industry: Used for degreasing and cleaning fabrics.
Health and Safety Concerns:
Short-term exposure: Can cause dizziness, headaches, nausea, and irritation to the
eyes and respiratory system.
Long-term exposure: Prolonged inhalation can lead to neurological effects, such as
peripheral neuropathy (nerve damage in hands and feet), characterized by numbness
and muscle weakness.
Environmental concerns: As a VOC, hexane contributes to smog formation when
released into the atmosphere.
Why is Hexane Controversial in Food Production?
In the food industry, hexane is primarily used to extract oils from seeds because it is
efficient and cost-effective. Although most of the hexane is removed during processing,
trace amounts can remain in the final product, which has raised concerns among
health-conscious consumers. Regulatory agencies, like the FDA and EPA, deem the
residual amounts in food safe, but many consumers prefer products that use
mechanical extraction methods (like cold pressing) to avoid chemical solvents
altogether.

Now CHATGPT’s quite different version
The assertion that seed oils cause addiction to foods by destabilizing the body’s natural
processes is a topic of debate. While some claim that seed oils contribute to overeating
and health issues, current scientific evidence does not support the notion that seed oils
inherently cause food addiction or significantly disrupt the body’s natural processes.
Understanding Seed Oils
Seed oils, such as canola, soybean, sunflower, and corn oil, are extracted from the
seeds of various plants. They are rich in polyunsaturated fatty acids (PUFAs),
particularly omega-6 fatty acids like linoleic acid. These oils are commonly used in
cooking and food processing due to their availability and favorable cooking properties.
The Role of Omega-6 Fatty Acids
Omega-6 fatty acids are essential fats that the body cannot produce on its own,
necessitating their inclusion in the diet. They play crucial roles in brain function, growth,
and development. However, concerns have been raised about the balance between
omega-6 and omega-3 fatty acids in the diet. Some suggest that a high intake of
omega-6s, relative to omega-3s, may promote inflammation, potentially leading to
various health issues. It’s important to note that the American Heart Association
supports an omega-6 PUFA intake of at least 5% to 10% of energy, stating that
reducing omega-6 PUFA intakes from current levels would more likely increase than
decrease the risk for coronary heart disease. citeturn0search34
Seed Oils and Food Addiction
The concept of food addiction involves the compulsive consumption of certain foods,
similar to substance dependence. Some individuals have speculated that seed oils
might contribute to such behaviors by affecting the body’s natural processes, possibly
through mechanisms like inflammation or oxidative stress. However, there is currently
no scientific evidence to support the idea that seed oils cause addictive eating
behaviors. The American Heart Association has stated that concerns about seed oils
causing health issues are misleading, emphasizing that these oils are not to be feared.

Inflammation and Oxidative Stress
While it’s true that PUFAs can oxidize, leading to the production of free radicals, the
body has mechanisms to manage oxidative stress. Moderate consumption of seed oils,
as part of a balanced diet, is unlikely to overwhelm these systems. Additionally,
research indicates that linoleic acid does not increase markers of inflammation,
countering the argument that seed oils promote inflammatory processes.

Dietary Balance and Overall Health
It’s essential to consider overall dietary patterns rather than focusing solely on individual
components like seed oils. A diet high in processed foods, which often contain seed
oils, can contribute to health issues, but this is likely due to factors such as high sugar
content, low fiber, and excessive calorie intake, rather than the seed oils themselves.
Emphasizing whole foods, including fruits, vegetables, lean proteins, and whole grains,
while moderating the intake of processed foods, is a more effective strategy for
maintaining health.
Conclusion
Current scientific evidence does not support the claim that seed oils cause addiction to
foods by destabilizing the body’s natural processes. While it’s important to maintain a
balanced intake of omega-6 and omega-3 fatty acids, moderate consumption of seed
oils as part of a varied and balanced diet is not associated with adverse health effects.
Focusing on overall dietary quality and lifestyle factors remains the cornerstone of
healthful eating.
What is hexane?
Yes, hexane is commonly used in the production of seed oils through a process called
solvent extraction.
How Hexane is Used in Seed Oil Production:
Seed Preparation: Seeds (such as soybeans, canola, sunflower, and corn) are cleaned,
dehulled, and crushed.
Solvent Extraction: Crushed seeds are soaked in hexane, which efficiently dissolves
and extracts the oil from the seed material.
Separation: The hexane-oil mixture is heated to evaporate the hexane, leaving behind
the extracted oil.
Recovery and Reuse: The evaporated hexane is condensed and recycled for reuse in
further extraction processes.
Refining: The extracted oil is then refined, bleached, and deodorized for commercial
use, while the remaining seed material (called meal or cake) is processed into animal
feed.
Why Hexane is Used:
High efficiency: Extracts a large amount of oil from seeds compared to mechanical
pressing.
Cost-effective: Reduces production costs, making seed oils cheaper.
Scalability: Ideal for large-scale industrial oil production.
Health Concerns:
While most of the hexane is removed during processing, trace amounts may remain in
the final oil products. Regulatory agencies like the FDA and EPA consider these trace
amounts safe for consumption. However, some consumers are concerned about
potential long-term health impacts and prefer oils made through cold-pressing or
expeller-pressing, which do not use chemical solvents.
Alternatives to Hexane Extraction:
Cold-Pressed Oils: Extracted without heat or solvents, retaining more nutrients but
yielding less oil.
Expeller-Pressed Oils: Uses mechanical pressure instead of chemicals, often resulting
in a higher-quality product.
