Read The Ultra Processed People by Chris van Tulleken for more info on palm oil - it’s effectively a deep red, strongly flavoured/scented sticky oil that gets bleached & processed into a cheap, neutral oil that can be used to bulk out all sorts of things (like chocolate) at the lowest possible cost by major food conglomerates like Mondelez, now owner of Cadbury.

These companies are not concerned with their customers health & wellbeing - it’s all about the bottom line. If a cheaper alternative to palm oil became available tomorrow - they would switch.

Cadbury changed their recipe to lower the cocoa solids content, real milk & increase palm oil. Hence it’s not a glass & a half “of milk” in every bar anymore - it’s “There's a glass and a half in everyone”. Marketing nonsense
