Key Moments
Seed oils aren't toxic: 25 years of research shows benefits
Professor Sarah Berry, with 25 years of fat research, debunks the seed oil panic. The correlation between seed oil consumption and disease rates ignores confounders like ultra-processed food, sedentary lifestyles, and stress. Epidemiological studies consistently show that increasing omega-6 polyunsaturated fat intake reduces coronary heart disease risk by up to 30% and lowers LDL cholesterol.
"What you see is consistently there is a favourable effect from increasing omega-6, which is a good marker of seed oil intake, with a reduction in coronary heart disease."
Cold-pressed and refined seed oils show no health difference in trials
Randomized controlled trials comparing cold-pressed versus refined seed oils show no difference in inflammation or oxidative stress outcomes. While refining removes some phytonutrients like vitamin E and polyphenols, the end product is safe with no harmful chemicals remaining. The price premium for cold-pressed may not be justified for most people.
"There's been a couple of randomized control trials that have actually compared coal press versus the refined oil, and they actually don't show any difference in many of the different outcomes."
