The American Heart Association says seed oils are heart-healthy. They’re wrong.
Seed oils aren’t food - they’re chemically extracted factory products created using solvents, bleaching, and deodorizing. You can’t squeeze a soybean and get oil like you do with an olive.
These oils didn’t exist in our diet until the 1920s-1940s.
The mainstream argument: Seed oils lower LDL cholesterol, so they must be good for your heart.
What they ignore: Omega-6 fats from seed oils oxidize inside LDL particles. Oxidized LDL drives atherosclerosis. Seed oils are causing the problem they claim to solve.
Our ancestral omega-6 to omega-3 ratio was 1:1. Today it’s 20:1. This shift matches the rise in heart disease perfectly. Meanwhile, saturated fat consumption stayed stable. Saturated fat isn’t the villain.
The Minnesota Coronary Experiment showed seed oil diets increased overall mortality. A 16-year study on ketogenic diets (high saturated fat, low seed oils) showed 24% lower all-cause mortality and significantly lower heart disease.
McDonald’s used beef tallow for fries until the 1990s. Then they switched to “healthy” vegetable oils under industry pressure. We got sicker.
What to use instead: Olive oil, avocado oil, coconut oil, grass-fed butter, ghee, beef tallow, lard. These are natural fats humans consumed for thousands of years.
The half-life of omega-6 in your cells is 2 years. It takes time to reverse the damage, but lowering omega-6 intake is one of the most important steps for longevity and metabolic health.
