Seed Oils Take Nearly 2 Years to Clear Out of Fat Stores.

A 1966 study revealed that linoleic acid, the main omega-6 fat in seed oils like soybean and sunflower, lingers in your body’s fat tissue with a half-life of ~680 days (~1.9 years). Men switching to high-LA diets saw adipose LA rise from 11% to 32% over 5 years, showing it takes years to fully reflect dietary shifts. While fat tissue changes slowly, linoleic acid in blood or cell membranes turns over in days to months, meaning health benefits from cutting seed oils could appear sooner.

Why does this matter? Too much linoleic acid from seed oils can tip your body's omega-6 to omega-3 balance, leading to inflammation that might cause heart issues or joint pain over time. It's like junk food sticking around in your system, making it harder for healthier fats to do their job.

Reduce seed oil intake by swapping for olive oil or avocado oil, which are lower in omega-6 and richer in heart-healthy fats, to potentially speed up benefits to your lipid profile.
