Olive Oil Packaging: Glass Is Clean Until You Need a Cap
Olive oil packaging is usually judged by the bottle, but the bottle is rarely the problem. Glass is inert, yet it needs a cap, and plasticizers migrate from cap gaskets into the oil, sometimes above EU limits. Microplastics enter during milling, not the container. Oleaphen's Chief Scientist explains what keeps an olive oil clean: a plastic-free mill, no plastic closure, a cold chain, and testing.

High Phenolic Olive Oil and Brain Health: What the Evidence Actually Shows
What does the science really say about high phenolic olive oil and brain health? A large Harvard cohort linked daily olive oil to 28% lower dementia mortality, and a clinical trial found that only the phenol-rich oil, not refined oil, improved the blood-brain barrier. The molecules doing the work are the polyphenols, above all oleocanthal, and truly high-oleocanthal oil is rare. Written by Oleaphen's Chief Scientist, this evidence-weighted guide sorts the strong findings from the early ones.
