The Truth About Vegetable Oils and Your Skin - AI Podcast

8 minutes

Story at-a-glance

Linoleic acid (LA), the primary polyunsaturated fat in vegetable oils and commonly found in processed foods, accumulates in skin tissue and increases your risk of sun-induced oxidative damage
Once stored in body fat, LA leaks into circulation for years, continuously influencing your skin cell membranes even after your dietary intake of LA has stopped
Pentadecanoic acid (C15:0), found in grass fed dairy and ruminant animals, helps displace LA from cell membranes, reduces lipid peroxidation, and supports mitochondrial and structural integrity
Supplementing with 2 grams of C15:0 per day, combined with a low-LA diet and metabolic support, significantly shortens LA clearance from two to three years to 12 to 18 months
Proper sun exposure becomes safer once LA has been displaced from skin membranes, but caution is needed during early clearance stages to avoid UV-induced inflammation from residual LA
