Seed oils, often marketed as “heart-healthy,” come with serious health risks due to their high levels of polyunsaturated fatty acids (PUFAs), especially omega-6 fatty acids.
These oils include soybean, canola, corn, sunflower, safflower, cottonseed, and grapeseed oil.
Why you Need To Avoid Seed Oils
- High in Omega-6 Fatty Acids (Causes Chronic Inflammation)
Excessive omega-6 intake disrupts the omega-3 to omega-6 ratio, leading to chronic inflammation, a root cause of obesity, diabetes, heart disease, and cancer.
Historically, humans had an omega-6 to omega-3 ratio of 1:1, but modern diets push it to 20:1 or worse due to seed oil consumption.
- Oxidative Stress and Cellular Damage
Seed oils are highly unstable and oxidize easily, forming toxic aldehydes and lipid peroxides that damage cells, DNA, and proteins.
These oxidized fats accelerate aging, neurodegeneration (Alzheimer’s, Parkinson’s), and heart disease.
- Endocrine Disruption (Lowers Testosterone, Raises Estrogen)
The breakdown of seed oils produces compounds that disrupt hormone balance, reducing testosterone levels in men and increasing estrogen dominance.
This contributes to low libido, infertility, gynecomastia (“man boobs”), and feminization in men.
- Promotes Insulin Resistance and Obesity
Seed oils damage mitochondrial function, impairing the body’s ability to use fat for energy.
They are linked to fatty liver disease, metabolic syndrome, and insulin resistance, which leads to diabetes and obesity.
- Raises Risk of Heart Disease (Despite the Lies)
While seed oils lower LDL cholesterol, they increase small, dense LDL particles, which are more likely to cause arterial plaque buildup.
High omega-6 intake is associated with higher cardiovascular mortality, despite being falsely promoted as “heart-healthy.”
- Heat Instability (Creates Toxic Byproducts in Cooking)
When heated, seed oils release acrolein, trans fats, and toxic aldehydes, which are linked to cancer, lung damage, and inflammation.
Unlike stable saturated fats (like beef tallow, butter, and coconut oil), seed oils turn rancid quickly when exposed to light, heat, or oxygen.
Best Alternatives to Seed Oils
To avoid the dangers of seed oils, use stable, natural fats:
Beef Tallow (Best for deep frying, cooking)
Butter or Ghee (Rich in fat-soluble vitamins)
Coconut Oil (Highly stable, antimicrobial)
Olive Oil (Cold use, avoid heating)
Avocado Oil (Higher smoke point, but still limited heat use)
Seed oils are toxic, inflammatory, and hormone-disrupting substances that should be avoided.
Stick to natural animal fats and traditional saturated fats to protect your testosterone, metabolism, and overall health.
